Heat exchange core for two-way inlet/outlet air hose

Abstract

The invention relates to the field of air regulation, in particular to a heat exchange core for a two-way inlet / outlet air hose. The invention aims to solve the problems of great occupied space and high reformation cost of an existing fresh air system adopting a prismatic heat exchange core. To achieve the aim, the heat exchange core disclosed by the invention comprises a prismatic main body, wherein at least two first inner edge surfaces and at least two first outer edge surfaces are formed on the first side of the prismatic main body in the X direction; at least two second inner edge surfaces and at least two second outer edge surfaces are formed on the second side of the prismatic main body in the X direction; a plurality of air inlet flow channels are formed between the second outer edge surfaces and the corresponding first inner edge surfaces; a plurality of air outlet flow channels are formed between the first outer edge surfaces and the corresponding second inner edge surfaces;the plurality of air inlet flow channels and the plurality of air outlet flow channels are arranged in a cross manner. The heat exchange core disclosed by the invention can be applied to the two-way inlet / outlet air hose; occupied space of the heat exchange core is reduced and reformation 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...
