Double-runner same-layer heat exchange type total heat exchange core body, air conditioner and home appliance

Abstract

The invention provides a double-runner same-layer heat exchange type total heat exchange core body, an air conditioner and a home appliance. The double-runner same-layer heat exchange type total heatexchange core body comprises multiple heat exchange monomers staggered and laminated; the heat exchange monomers comprise first cross flow sections, reverse flow sections and second cross flow sections; the first cross flow sections and the second cross flow sections are arranged at the two ends of the reverse flow sections for connection; the first cross flow sections are divided into upper and lower layers for air feeding and discharging; and the second cross flow sections are divided into upper and lower layers for air feeding and discharging. Runners in the total heat exchange core body are recombined to convert traditional upper / lower-layer heat exchange of cold and hot airs to synchronous implementation of upper / lower-layer heat exchange and left / right-layer heat exchange; and freshair channels and air return channels exchange heat on the same heat exchange layers of the reverse flow sections, so that the heat exchange area of the reverse flow sections is increased, and the heatexchange efficiency of the total heat exchange core body is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange cores, in particular to a dual-flow same-layer heat exchange type full heat exchange core, air conditioners and home appliances. Background technique [0002] People's increasing requirements for indoor air quality and health and comfort have resulted in a high energy consumption of fresh air. The application of air waste heat recovery technology can alleviate the contradiction between ensuring fresh air quality and increasing energy consumption, but the problems of low heat exchange efficiency and large resistance loss of the traditional total heat recovery core restrict its development and popularization. The main factors affecting the heat exchange efficiency of the core body are: the internal heat exchange surface area of ​​the core body, the form of the heat exchange channel of the core body, the circulation time of the air in the full heat exchange core body, and so on.

AI Technical Summary

Problems solved by technology

[0004] In the prior art, such as the Chinese patent CN206669981U discloses a spiral rotating core body, but its structure is complex and the air circulation resistance is large; the total heat exchange core skeleton support structure described in the Chinese patent CN208312643U has uniformly distributed through holes, forming The honeycomb-like shape can prolong the exchange and time of hot and cold air in the total heat exchange core, but cannot increase the heat exchange area; the total heat exchange core described in patent CN207865646U has an S-shaped channel, and the structure is simple, but the heat exchange efficiency is not high. The circulation area is still the upper and lower layers, but the S-shaped channel increases the circulation time of the air in the core; the total heat exchange core described in patent CN206479068U is a quadrilateral heat exchange core made of aluminum and has high thermal conductivity, but Can not transfer mass
