1 Claim. (Cl. 210150.5)

This invention relates to heat transfer apparatus and is particularly concerned with a combination heat transfer device and filter.

An object of the invention is to provide a heat transfer device in combination with a filter 5 24 and 26 are spaced by means of two side porwherein, due to the peculiar nature of the filtertions or rails 28 and 30 which assembly forms a ing medium, the effective area of the heat transframe open at both sides thereof. fer surface is greatly increased. The frame, formed by the two side rails 28 and Another object of the invention is to provide 30 of the headers 24 and 26, together with the an oil cooler and filter wherein water or other in attached tubes is then preferably placed on a cooling medium may be circulated through a graphite plate and metal powder is poured plurality of conduits such as, tubes which are around the tubes and into the frame which concarried by and bonded to a porous metal block fines the powder.

These connections ,36 and 38 or 48 and 50.

tubes, spaced in the desired relation to one another, are held between a pair of spaced headers 24 and 28 to which they are brazed or welded or otherwise hermetically secured. The headers gsomw is obteined which provides excellent conduction between the filter block and the cooling medium. While the description herein has been limited for my desired purpose. Likewise any other hsve in the filter block. The sintering temperstures are well-known in the srt as ere alloy types of powders. The descriptions of various silo! powders will be found in Olt Patent 2,273,589. Oombinstions 0! metal powder used to mske filtering or metering elements may be noted in Koehring Patent 2,198,702. Both of the foregoing petents ere assigned to the assignee of the present invention.
