Novel micro-through plate and heating radiator and air conditioner tail end equipment provided with same

Abstract

The invention relates to the field of heat exchange, and discloses a novel micro-flow plate. The micro-flow plate is formed by compounding two plate pieces and comprises an inner side medium flow channel and two outer side heat exchange surfaces; the inner side medium flow channel is composed of a distribution channel, a collecting channel and net-shaped crossed micro heat exchange channels; a first medium enters the micro-flow plate and is distributed by the distribution channel and then enters the net-shaped crossed micro heat exchange channels to be sufficiently turbulent, heat is exchangedbetween the two outer side heat exchange surfaces and the second medium on the outer side of the micro-through plate when flowing through the micro heat exchange channels; a heat conduction componentused for increasing the heat exchange area of the second medium is arranged on the outer side heat exchange surface of at least one of the two plate pieces. The micro heat exchange channels are uniformly distributed in the whole novel micro-through plates in a net-shaped staggered mode and ensures that the first medium fully utilizes the heat exchange surface; further, a heat conduction part is arranged on the outer side heat exchange surface of at least one plate piece, the heat exchange area of the second medium is increased through the arrangement of the heat conduction component, and themaximization of the heat exchange effect is facilitated.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to a novel micro-channel plate, radiators and air-conditioning terminal equipment provided with the micro-channel plate. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in the field of home appliances, or in chemical, petroleum, power, food and many other industrial productions, and can be used as heaters, coolers, condensers, evaporators and reboilers. [0003] In my country, indoor heating devices in winter in the north have become a standard configuration for families, and indoor heating in winter in the south has also received increasing attention and gradually entered thousands of households. With the improvement of national environmental protection requirements, coal boilers that provide 60-90°C circulating hot water will be required to...

AI Technical Summary

Problems solved by technology

[0006] At present, radiator heat exchangers generally have one or more of the following problems. 1) Metal parts with thicker materials are used, which are heavy and costly

2) There are many welding processes or complex assembly processes, the manufacturability is not good, and the subsequent surface treatment affects the heat transfer effect

3) The distribution of the heat exchange medium is uneven, the diameter of some flow channels is large, there is temperature stratification, and the heat exchange efficiency is low

4) It is suitable for heat exchange at high water temperature of 60-90 degrees, but the heating effect is poor for low water temperature of 40-60 degrees

5) There is a large amount of water stored in the heat exchanger, which increases the total weight of the radiator, reduces the response speed of heat exchange, and causes heat loss
