Description
One subject in accordance with the invention at hand is a ventilation system in accordance with the generic term of claim 1. The system may be used e.g. for climate control of seat surfaces, particularly in vehicles.
For the ventilation of seat surfaces, it has been known, for example from DE 197 36 951, to arrange a space fabric on the surface of the seat and to guide a flow of air through it.
From DE 195 27 352 C2 it has been known to design the foam padding of a seat in the shape of nubs.
Some applications require alternative or improved options that are advantageous with regard to their manufacturing costs, to their ability to create a pleasant climate, to an efficient distribution of thermal energy and/or to their energy consumption.
Summary of the invention
To improve the prior art, a technical concept with the characteristics of claim 1 is being proposed. Additional advantageous embodiments can be gleaned from the additional claims and the subsequent description.
In the following, details of the invention will be explained. These statements should make the invention comprehensible. However, they have only exemplary character. Of course, individual or several characteristics as described may be omitted, modified or supplemented within the framework of the invention defined by independent claims. Also, the characteristics of various embodiments may be combined with each other. The decisive factor is that the concept of the invention be essentially implemented. If one characteristic can be partially fulfilled, this will include that this characteristic is fulfilled completely as well, or is essentially completely fulfilled. "Essentially" shall denote in this context in particular that the implementation permits obtaining the desired benefit to a recognizable extent. This may mean in
particular that a corresponding characteristic is met at least at 50%, 90%, 95% or 99%. If a minimum amount is indicated, it will of course be possible to use more than such a minimum amount. If the number of a component is indicated with at least one, this shall also include embodiments with two, three or any other multitude of components. What is described for one object may also be applied to the overwhelming part or totality of all other objects of the same type. Unless stated to the contrary, intervals shall include their boundary points.
In the following, reference will be made to:
FIG. 1 Vehicle 1 with a seat as climate conditioned object 2 in a partial longitudinal cut
FIG. 2 Enlarged view of a climate conditioning device 10 for the climate conditioned object 2 of Fig. 1 in a length section of a seat cushion
FIG. 3 Perspective view of a climate control device 20 of climate conditioned object 2 of Fig. 2
FIG. 4 Alternative embodiment of a climate control device 20’ of a climate conditioned object 2 of Fig. 2
The invention is particularly well suited for use in a vehicle 1 as in Fig. 1. This denotes in particular all land, water or aircraft such as, for example, an airplane, a rail vehicle, a ship or a motor vehicle.
The invention is moreover suited for use in all objects, whose surface is to be conditioned at least partially in such a way that at least certain climatic parameters, for example temperature or humidity, are kept at a desired interval or at a certain value at least close to the surface. Beds in vehicles, in tents or in houses are one field of possible use. Therefore, "climate conditioned object" denotes in particular all components with which a user may come in contact, especially in a passenger compartment of a vehicle 1, such as a steering mechanism for a vehicle, a dashboard, an armrest, a door paneling, a seat cover, a seat or a cup holder. It may be useful for at least one vehicle to have at least one climate conditioned object 2,
such as, for example, a seat. This permits a pleasant climate of a passenger even during long trips under extreme conditions.
Figure 1 shows a vehicle seat 5 with a seat part 6 and a backrest 7. In the exemplary embodiment these are covered with a non-perforated leather cover. The seat part has a contact surface, which is usually occupied by a passenger when the seat is in use.
It may be useful for at least one climate conditioned object 2 to have at least one cushion 8, such as a block of foam polyurethane.
The cushion 8 has a surface 30, which is divided into several air exchange surfaces 35, divided by grooves in a user directed A-side.
The cushion is provided with a multitude of through-holes 88, connecting A-and B-side, which is oriented away from the user.
Preferably each of the air exchange surfaces 35 has at least one through-hole 88.
It may be useful for at least one climate conditioned object to have at least one cover 9. This denotes any kind of surface covering the padding, for example textile covers or an external skin of a padding foam. But the invention is especially suitable to improve the comfort of leather surfaces.
It may be useful for at least one climate conditioned object 2 to have at least one climate conditioning device 10. This denotes all devices that serve to regulate one or more climate parameters, like temperature, humidity and air movement in an area to be conditioned, for example surfaces touched by the user (s) in the passenger compartment of a vehicle 1.
It may be useful for at least one climate conditioning device 10 to have at least one temperature control device 70, e.g. a thermoelectric device. A thermoelectric device shall especially mean a solid-state active heat pump. It usually is a flat part, which under consumption of electrical energy transfers heat from its one side to its other side. PTC-heaters, heating wires or ventilators are other examples for a temperature control device.
The climate conditioning device 10 preferably has an air guiding device 90, which allows a fluid to pass through it or along its surface. Therefor it is provided with one or more hollow spaces 74. Such a hollow space can be formed e.g. like a channel or a multitude of channels running in parallel, side-by-side or interwoven with each other. The fluid preferably is air. The channels are preferably tubes or tubes with side branches.
It may be useful for at least one climate conditioning device 10 to have at least one air moving device 57. This denotes any device that can be used for a change of air in a specific area, for example, an on-board air conditioner or axial or radial ventilators. Some applications require two air moving devices 57 per climate conditioned object 2 or per temperature conditioned surface. The air moving device 57 pulls air from the surrounding into the air moving device 57 and pushes it into a main channel 82 of the air guiding device 90. The main channel 82 can be a part of the housing of the air moving device 57, like in Fig. 4. It can also be a separate component like in Fig. 2 + 3. The main channel can contain at least one climate conditioning device 10, like TEDs (thermoelectric devices) and/or resistor heaters. Preferably it contains TEDs and a resistor heater.
In a preferred embodiment the air moving device 57 is a flat axial ventilator, combined with a temperature control device 70 as a preassembled module. The ventilator preferably has a thickness of less than 2 centimeters, preferably less than 15 mm. This leads to a very flat unit, which can be put under any vehicle seat.
The main air channel 82 provided with at least one fork, resulting the central air collector to split up into at least two or more air guiding branches 60 A, B.
An air guiding branch is preferably at least partly built of one or more fluid conductors, e.g. pipes or tubes. Such a fluid conductor 60 is preferable at least partly made of an elastic but tear-resistant and pressure-resistant material. That can be one or more of these components: rubber, polyurethane (especially resistant to hydrolysis) , silicone, latex, PVC or a gel of synthetic material like polyurethane gel. The material should have an elongation rupture of at least 100%. Alternatively or additionally, a fluid conductor can be made at least partially of a textile material, for example of a weave, fabric, knit or mesh. This will permit high flexibility with low weight. The fluid conductor 60 can have an outer cross-sectional diameter of e.g. between 3 and
10 mm, especially for areas, where much heat shall transfer through the walls of the fluid conductor 60, while the fluid is transported through the fluid conductor 60. The fluid conductor 60 can have an outer cross-sectional diameter of e.g. between 26 and 36 mm, especially for sections, where the fluid 44 shall pass through the fluid conductor 60 with a minimum heat transfer via the walls of the fluid conductor 60.
At least one fluid conductor 60 serves as a supply tube to supply at least one air exchange surface 35 with thermally conditioned air. In summer this air is cooled by the temperature control device 70. In winter it is heated. Especially big air exchange surfaces 35 are better supplied with a multitude of supply tubes. It is possible to connect each air exchange surface 35 with its own supply tube. But in one preferred embodiment the air exchange surface 35A of a central seat cushion are supplied via two main branches 60A and 60B having a multitude of side branches 62.
In a not shown vehicle, cabin or building the invention could be used to control the temperature of a bed, a cover sheet or a mattress. For that purpose one or a multitude of air exchange surfaces 35 are arranged in one or more of these subjects. Preferably an air exchange surface 35 in an area of a head of a user is provided with cooled air. Additionally or alternatively an area of feet of a user is warmed. A simultaneous combination is be possible, e.g. if at least one air exchange surface 35 is warmed in the waste air stream of the heat removal device or if the waste air is directed to the feet of the user.
Any application described above can also be used for heating purpose just by changing the operation direction of the heat pipes, by inverting the circulation direction of the air and/or by switching the polarity of temperature control device 70.
