Heat exchange core plate, total heat exchange module, air interchanger and air conditioner

Abstract

The invention provides a heat exchange core plate, a total heat exchange module, an air interchanger and an air conditioner. A first flow channel, a second flow channel and a steering flow channel connected between the first flow channel and the second flow channel are formed in one side face of the heat exchange core plate; an inclined flow guide surface is formed on the outer flow guide edge ofthe steering flow channel, and extends from a first flow channel side to a second flow channel side; the second flow channel comprises a plurality of parallel sub-flow channels; a flow channel communicating opening communicated with the steering flow channel is formed in the end, close to / connected with the steering flow channel, of each sub-flow channel; and the flow channel communicating openings of the plurality of parallel sub-flow channels are formed in the mode that the opening direction corresponds to the inclination direction of the inclined flow guide surface in a staggered way. By means of the technical scheme, under the cooperation of the inclined flow guide surface and the flow channel communicating openings formed in a staggered mode, fluid flowing out of the steering flow channel is evenly distributed into the plurality of sub-flow channels, so that even distribution of the fluid is achieved; and uniform heat exchange in the heat exchange process is further ensured.

Description

technical field [0001] The invention relates to a total heat exchanger for an air conditioner, in particular to a heat exchange core plate, a total heat exchange module, a ventilation device and an air conditioner. Background technique [0002] With the development of society, people's living standards have been greatly improved, and air conditioners have become one of the requisite household appliances in people's lives. However, the traditional air conditioner has a single function and cannot meet people's pursuit of high-quality healthy life. The outbreak of the new crown virus has aroused people's attention to healthy life. Therefore, the development of healthy and energy-saving air conditioners has become one of the future development trends. [0003] The existing total heat exchange core is used as air-conditioning exhaust ventilation equipment. Its working principle is: when the product is working, when the indoor exhaust air and the fresh air flow through the core ...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the working efficiency of the total heat exchange core determines the working efficiency of the total heat exchanger product. In the prior art, the vertical cross flow of air between the layers is mostly used for heat exchange, and the heat exchange time is shorter than the heat exchange efficiency. Low; in order to improve the working efficiency of total heat exchanger products and reduce operating costs, a total heat exchange core with a higher heat exchange rate is urgently needed
