Heat exchange core for bidirectional air inlet and outlet pipe

Abstract

The invention relates to the field of air conditioning, in particular to a heat exchange core for a bidirectional air inlet and outlet pipe. According to the heat exchange core the problem that an existing fresh air system adopting a prismatic heat exchange core is large in occupied space and high in transformation cost. The heat exchange core comprises an annular body, the annular body is provided with a first inner ring surface and a first outer ring surface along the axial first side, the annular body is provided with a second inner ring surface and a second outer ring surface along the axial second side, a plurality of air inlet flow channels are formed between the second outer ring surface and the first inner ring surface, a plurality of air outlet flow channels are formed between thefirst outer ring surface and the second inner ring surface, and the plurality of air inlet flow channels and the plurality of air outlet flow channels are arranged in a crossed mode. The heat exchange core can be applied to the bidirectional air inlet and outlet pipe, the occupied space of the heat exchange core is reduced, and the transformation cost is reduced.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a heat exchange core for a bidirectional air inlet and outlet duct. Background technique [0002] The air pollution report released by the International Energy Agency clearly mentioned that as many as 97% of Chinese people are exposed to the harm of PM2. The cardiopulmonary immunity of people in heavy smog areas has dropped by 10%. In recent years, due to the intensification of air pollution and frequent smog, people cannot often open windows for ventilation. As a result, bacterial particles such as PM2.5 in the indoor air can easily invade the lungs and respiratory tract, causing cough, asthma, pneumonia and even lung cancer. At the same time, it also causes cross-infection among people, which is regarded as the root cause of respiratory epidemics. In addition, people stay in a closed indoor environment for a long time, and the decoration pollutants such as formaldehyde and TVO...

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problems that the existing fresh air system using a prismatic heat exchange core occupies a large space and the cost of renovation is high, the present invention provides a two-way inlet and outlet air duct A heat exchange core, the heat exchange core includes an annular body, a first inner annular surface and a first outer annular surface are formed on the first side of the annular main body along the axial direction, and a second inner annular surface is formed on the second axial side of the annular main body. A second inner ring surface and a second outer ring surface are formed on the side, and a plurality of air inlet channels are formed between the second outer ring surface and the first inner ring surface, and the first outer ring surface and the A plurality of air outlet runners are formed between the second inner ring surface, and the plurality of air inlet runners and the plurality of outlet runners are arranged in a cross manner
