Total heat exchanger

Abstract

This invention discloses one total heat exchanger device, which comprises one total heat exchanger filter chip, one heat conductive tube and one wind machine, wherein, the wind machine provides the dirty air for indoor and absorbs fresh air from outdoor tow flows; the total heat exchanger filter chip is relative to the above two flows with crossed distribution channels and gas-in channels to make the gas pass for total heat exchanging; the exchanger comprises at least one branch heat tube with multiple fins located on the conductive tube.

Description

【Technical field】 [0001] The invention relates to a heat exchange device, in particular to a total heat exchange device for improving indoor air quality and having a total heat exchange function. 【Background technique】 [0002] In actual daily life, in order to ensure the indoor air quality, it is often necessary to install an air conditioning system, especially in places where people are concentrated, such as auditoriums, large supermarkets, office buildings, etc., in order to discharge indoor pollutants and dirty air in a timely manner. Outdoors, and at the same time supplement the outdoor fresh air (fresh air) into the room to meet the needs of human health standards. [0003] However, directly replacing the indoor and outdoor air will bring a lot of energy loss. For example, in summer, the energy loss generated when a large number of fresh air (hot air) with a high outdoor temperature is used to replace the indoor cold air treated by air conditioning is very big.

AI Technical Summary

Problems solved by technology

Since the exchange of latent heat and sensible heat is completed by the two airflows of the intake air and the exhaust air passing through the multi-layer cross channels separated by the partitions, the exchange efficiency is completely determined by the functional paper between the partitions of the channels, but Functional paper is mainly appealing to the characteristics of strong hydrophilicity, which often cannot take into account the improvement of heat transfer, and there is still a lot of room for improvement in the efficiency of sensible heat exchange

[0009] (2) The air flow rate entering the air inlet of the corrugated plate is not uniform

Because the wind direction blown from the fan and the wind direction entering the small channel in the total heat exchange filter element are often not on a straight line, but at a certain angle, and at the end of the flow path formed by the filter element and the casing, there is a machine facing the main airflow. The end plate of the shell is subjected to the interaction between the secondary air flow directly impacting the end plate and the incoming main air flow and the turning effect, making the flow field in between very chaotic, resulting in most of the air flow entering the filter element converging on only a small part of the wave-shaped air inlet On the other hand, the uneven air volume distribution between the above-mentioned inlets is very unfavorable to the overall exchange efficiency
