Counter-flow type efficient energy-saving fresh air machine heat exchanger core

Abstract

The invention discloses a reverse-flow type efficient energy-saving fresh air machine heat exchanger core body, particularly conducts ventilation and heat exchange on indoor and outdoor cold and hot air in a reverse-flow mode, and belongs to the technical field of heat exchange. The flowing directions of the outdoor fresh air and the indoor exhaust air in the core body are reverse flow directions; a plurality of layers of heat-conducting fins are arranged in the core body; a plurality of layers of heat-conducting fin supporting bodies are arranged in the core body; the core body is formed by alternately stacking a layer of heat-conducting sheet support body and a layer of heat-conducting sheet; outdoor fresh air and indoor exhaust air flow in the core body in a mutually alternate interlayer mode. An outdoor fresh air inlet and an indoor exhaust air outlet are formed in one side of the core body; an indoor exhaust air inlet and an outdoor fresh air outlet are formed in the other side of the core body; the two column-shaped air ports of the heat-conducting fin supporting body are arranged in a crossed mode and provided with a plurality of air flow guide plates and a plurality of heat-conducting fin supporting points. A heat exchanger core body of a reverse-flow type efficient energy-saving fresh air ventilator is an important component for cold and hot energy recovery of the fresh air ventilator.

Description

technical field [0001] The invention belongs to the technical field of heat exchange, and in particular relates to a counter-flow high-efficiency and energy-saving fresh fan heat exchanger core. Background technique [0002] With the continuous development of science and technology, the varieties of interior decoration materials are changing with each passing day, and various styles of decoration effects are emerging in an endless stream, but the problem of indoor air pollution is becoming more and more serious. On the agenda, people urgently need to solve the problem of indoor air pollution and poor indoor air. Among many methods, indoor ventilation is a better method: it not only solves the problem of indoor air pollution, but also solves the problem of unfresh indoor air, so the products of fresh air fans have gradually entered people's lives. [0003] When the new fan is used for air conditioning and cooling in summer and indoor heating in winter, it is necessary to ens...

AI Technical Summary

Problems solved by technology

[0005] Due to the existing fresh air fans on the market, the flow mode of outdoor fresh air and indoor exhaust air in the core body of the fresh air fan heat exchanger is a positive cross flow instead of a counter flow method, so the sensible heat and total heat exchange of the fresh air fan heat exchanger core low efficiency
