Claims (8)

A cylindrical body part is provided, and heat exchange fins are provided outside and inside the cylindrical body part to exchange heat between gases passing through the inside and outside of the cylindrical body part. A heat exchanger made of a metal material,
The heat exchange fin is formed of a metal plate-like body, and the metal plate-like body is inserted into a slit provided in the cylindrical body portion and fixed, thereby being disposed at a predetermined position. The heat exchanger is characterized in that the space between the slit and the metal plate-like body is hermetically sealed by being applied. The heat exchanger according to claim 1, wherein the coating material contains a crystalline carbon material such as a carbon nanotube and is applied to at least a part of the surface of the metal material . The heat exchanger according to claim 1 or 2 , wherein the coating material is applied to at least a part of the surface of the metal material outside the cylindrical body portion . The metal plate-like body constituting the fin for heat exchange is provided with a step portion for positioning to prevent the metal plate-like body from being inserted into the slit beyond a predetermined dimension. The heat exchanger according to 2 or 3 . The cylindrical body portion and the fin for heat exchange provided in a plurality of stages in the axial direction of the cylindrical body portion are formed in a plate shape, and the fin surface is inclined in the axial direction of the cylindrical body portion. ,
The heat exchanging fin extends across the inner side of the cylindrical part with a gap extending between the inner side surface of the cylindrical part and an end extending to the outer side of the cylindrical part. Provided,
5. The heat exchanger according to claim 1, wherein the heat exchange fins adjacent to each other in the axial direction are provided so as to intersect each other in a planar arrangement. A heat exchanger that heats the air while the air is sent by the air blower, and a heat exchanger that absorbs heat of the air on the exhaust side heated by the heater and gives heat to the air on the air intake side A deodorizing and sterilizing apparatus for decomposing odorous components in the air and sterilizing bacteria and viruses in the air, etc., in the heat exchange unit, according to claim 1, 2, 3, 4 or 5. A deodorizing and sterilizing apparatus using a heat exchanger . The blower means is constituted by a first blower fan arranged at the intake port of the device and a second blower fan arranged at the exhaust port of the device,
The first blower fan and the second blower fan are arranged in the casing in the order of the heating unit, the catalyst unit, and the heat exchanger from the first blower fan side to the second blower fan. The deodorizing and sterilizing device according to claim 6, wherein the deodorizing and sterilizing device is arranged in series with the internal structure interposed therebetween . In order to prevent the gas from flowing directly from the first blower fan to the heating unit, it has a bottom portion arranged on the first blower fan side, and the heating unit, the catalyst unit, and the heat exchanger are inside. 8. A deodorizing and sterilizing apparatus according to claim 7, further comprising a bottomed cylindrical body disposed on the bottom .
