An oblique crossed type heat recovery device for a pipeline is composed of variable-diameter joints (1), adapting pipes (2), a heat-exchange air hose (3) and heat exchange cores (4). The four variable-diameter joints are arranged, and the two adapting pipes (2) are arranged. Each heat exchange core (4) is made of a multi-layer aluminum film (4-1). The heat exchange cores (4) are correspondingly arranged in the heat exchange air hose (3) and the adapting pipes (2). Each heat exchange core (4) is of a layered structure, every two layers are separated by an aluminum film, the end of each heat exchange core (4) is an intermittent plugging state, and each plugged three-dimensional face shape is an outwardly-protruding V-type triangular body (4-3); inlet air and exhausted air fully exchange heatin the heat exchange cores, after flow guide of adapting openings, staggered exhausted air layers and inlet air layers are formed in the heat exchange cores, each of the heat exchange cores is made of the aluminum film or other materials high in heat exchange efficiency, heat conduction between the inlet air and the exhausted air can be fully achieved, and the conduction efficiency is improved.
Description
technical field [0001] The invention relates to an obliquely crossed pipeline heat recovery device. More specifically, it involves using part of the pipelines in the fresh air system as the heat exchange medium to perform heat exchange between the air intake and exhaust air in the parallel section of the air intake / exhaust pipeline, and it is used as an oblique cross pipeline of the ventilation system alone Heat recovery unit. Background technique [0002] The heat recovery device in the ventilation system can complete the heat exchange between the air sent into the room and the air discharged from the outside, so that the fresh air can obtain a suitable temperature and humidity before it is sent into the room, thereby increasing comfort and reducing the heating / cooling system. purpose of energy consumption. The current fresh air system realizes this function by setting a heat recovery device in the main unit. [0003] The method of built-in heat recoverer in the host in ...
