Total heat exchanger core and total heat exchanger

Abstract

The invention provides a total heat exchanger core and a total heat exchanger. The machining efficiency and the heat exchange efficiency are improved, and even if degumming occurs between a core plate and a film, the problems of air leakage and air mixing can be effectively solved. The total heat exchanger core comprises a frame and a heat exchange core, the heat exchange core comprises a plurality of heat exchange core plates, the heat exchange core plates are vertically stacked, a plurality of airflow channels are formed in each heat exchange core plate, and the extending directions of the airflow channels of every two adjacent heat exchange core plates intersect with each other; and in every two adjacent heat exchange core plates, one heat exchange core plate is wrapped with a heat exchange film, and in every two adjacent heat exchange core plates, the air flow channel port part of one heat exchange core plate is sealed with the corresponding part of the other heat exchange core plate. According to the total heat exchanger core, the machining efficiency and the heat exchange efficiency of the core can be improved, and even though the heat exchange core plates and the heat exchange films are degummed, the problems of air leakage and air mixing between the adjacent heat exchange core plates can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of ventilation systems, in particular to a total heat exchanger core and a total heat exchanger with the total heat exchanger core. Background technique [0002] With the improvement of people's living standards, people's requirements for quality of life are also getting higher and higher. And because when the air conditioner works, the room is usually closed, resulting in long-term air stagnation in the room, and people's requirements for indoor fresh air are becoming more and more intense. The total heat exchanger is a kind of air purification equipment that discharges indoor dirty air and introduces outdoor fresh air to meet the user's requirements for indoor fresh air. When the total heat exchanger is working, it can use the core to exchange heat between the indoor dirty air and the outdoor fresh air, so as to preheat (cool) the introduced outdoor fresh air, thereby reducing energy consumption and impro...

Problems solved by technology

[0005] 1. When processing the total heat exchanger, after laying the bottom heat exchange core plate, apply glue on the surface of the heat exchange core plate ( figure 1 A is part of the glue-coated surface, including the surface of the connecting hoop of the core plate and each edge surface), and then covered with a layer of heat exchange film, and then the upper and lower surfaces of the penultimate heat exchange core plate are coated with glue and placed in place , and then cover another layer of heat exchange film until the uppermost heat exchange core board is laid, that is, except that the uppermost heat exchange core board only needs to be glued on its lower surface, and the lowermost heat exchange core board only needs to be glued on its upper surface. , the heat exchange core boards of other layers need to be glued on the upper and lower sides (the glued surface on the upper surface is the same as the figure 1 The glued surface on the upper surface of the middle and lowermost heat exchange core plate is the same, and the glued surface on the lower surface is symmetrical to the glued surface on the upper surface) to ensure reliable sealing with the heat exchange membrane, resulting in complicated installation process, low processing efficiency, and poor heat exchange performance. The glue coating area between the membrane and the heat exchange core plate is large, which seriously affects the heat exchange efficiency of the entire core;

[0006] 2. Once there is degumming between the heat exchange core board and the heat exchange membrane, the airflow will flow to other directions through the degumming gap between the membrane and the board, resulting in air leakage and cross air between adjacent core boards, affecting fresh air exchange wind effect
