Sensible heat air heat exchanger

Abstract

The invention discloses a sensible heat air heat exchanger comprising an upper base and a lower base. Four corners of the upper base and four corners of the lower base are supported by four supportingbars and an external frame is formed therefore; a plurality of first corrugated sheets and a plurality of second corrugated sheets perpendicular to the first corrugated sheets in a wave form are laminated in the external frame at intervals; air flow two air ducts flows oppositely from a lower side surface of a prism-tank shaped heat exchanger; a wave form direction is perpendicular to air duct flow directions; two ends of the wave form extend to form plane structures; each plane structure forms a water introducing groove on a prism lower side surface air duct entrance; and the first or secondcorrugated sheets are upwardly or downwardly perpendicular to two sides parallel to the wave form to form a wave crest equal to or higher than the wave form and raised sides sealed to corresponding sides of the adjacent second corrugated sheets or the first corrugated sheets. The sensible heat air heat exchanger is advantaged by high heat exchanging efficiency, small wind resistance, great air intake, noise prevention, large wind amount production, low die cost, great material utilization rate, great sealing property and easy condensate water collection.

Description

technical field [0001] The invention relates to an air heat exchanger, in particular to an air heat exchanger with high heat exchange efficiency, small air resistance, large air inlet area, no noise, favorable for making large air volume, low mold cost, high material utilization rate, good sealing performance and extremely low condensation water. Sensible heat air heat exchanger for easy collection. Background technique [0002] With the rapid improvement of people's living standards, people pay more and more attention to the comfort and health of the indoor environment. While regulating the temperature and humidity of the air, there are also requirements for indoor air quality (IAQ). In this context, small household air heat exchangers are being accepted and paid attention to by more and more families. In the indoor cooling and heating load, the fresh air load can often account for about 35%. For some particularly cold and hot areas, the indoor and outdoor temperature dif...

AI Technical Summary

Problems solved by technology

At present, the plate-type air sensible heat exchanger mainly adopts the following two methods: 1. Prismatic arrow-shaped air duct, this kind of heat exchanger has higher efficiency, but the disadvantage is that the wind resistance is large and the air inlet area is small, which is not conducive to the exchange of large air volume. High mold cost, low material utilization rate, poor sealing and poor collection of condensate, etc.; 2. Square bump type air duct, this kind of heat exchanger can save mold costs, has low requirements for materials, and has low material utilization. High efficiency and low wind resistance, but the disadvantages are low efficiency, insufficient material support, high vibration and noise, poor sealing and poor condensate collection, etc.
