Heat transmission belt of household air conditioner and its special structure during application

Abstract

The invention relates to a heat transmitting belt used for a household air conditioner and a special structure applied by the belt. The invention comprises a line of heat transmitting belts arranged in parallel, and a flow collecting tube is sheathed on the two ports of the heat transmitting belt. The heat transmitting belt is characterized in that the heat transmitting belt is a flat belt with a clear spacing which is more than 1mm and is less then 6mm. A refrigerant enters the belt through the flow collecting tube at the port of one side of the flat belts arranged in parallel and then flows over the flat belts which are arranged in parallel; the refrigerant flows out from the flow collecting tube at the port of the other end and flows over the flat belts which are arranged in parallel and finally carries out heat exchanging with the outside air to achieve the purpose of heat absorption. The invention is a heat exchanger which is wholly made of aluminum, which leads the manufacturing cost to be greatly reduced. The heat transmitting belt is also characterized in that the heat exchanging capability is high and the muff coupling of radiation aluminum plates can be avoided.

Description

technical field [0001] The invention relates to a heat transfer belt of a household air conditioner, in particular to a heat transfer belt in a heat exchanger of a household air conditioner. Background technique [0002] Currently known household air conditioners are generally divided into two categories: integral type and split type. The integral type is mainly window type air conditioner, while the split type includes wall-mounted air conditioner, ceiling type air conditioner, cabinet type air conditioner and other styles. Whether it is an integral household air conditioner or a split household air conditioner, its basic structure is composed of two parts, that is, an evaporator unit that absorbs heat by evaporating the refrigerant and a condensing unit that condenses and releases heat from the refrigerant. The part of the evaporating unit where the refrigerant evaporates and absorbs the heat of the indoor air is usually called the evaporator, and the part of the condensi...

AI Technical Summary

Problems solved by technology

The distance between tubes and tubes that make up such channels cannot be designed too small, usually more than 15mm. One is technical limitations, and the other is to allow aluminum fins to be sleeved to increase the heat exchange surface. If the distance is too small, the heat exchange capacity required by the air conditioner will not be achieved due to too much wind resistance

The disadvantage of this type of heat exchanger is that the heat exchange efficiency is not high, and a large number of copper tubes and aluminum heat sinks need to be used, and the manufacturing cost is relatively high.

Recently, people are trying to apply the parallel flow condenser technology that has been widely used in automobile air conditioners to household air conditioners. Any creative modification will copy the parallel flow condenser technology to the household air conditioner, and the result is that the cooling effect cannot meet the requirements of the household air conditioner and cannot be used instead

In addition, the parallel flow condenser also needs to insert corrugated aluminum fins between the flat parallel tubes to increase the heat exchange area, otherwise, the heat exchange capacity of the condenser will not meet the requirements

Since these two heat exchangers all need to weld heat-dissipating aluminum fins outside the tubes, there are two major disadvantages: one is that with use for a certain period of time, the welds between the welds will accelerate oxidation, and the heat-dissipating fins are too hot due to excessive heat dissipation. It is easy to deform if it is thin, and the heat dissipation performance will decline sharply. Second, due to the limitation of technical conditions, the gap between the heat dissipation aluminum sheets is very small, and the dirt and dust between the heat dissipation aluminum sheets cannot be cleaned thoroughly. After long-term use, it will also cause replacement. The sharp attenuation of thermal performance, if it is an evaporator, the dirt remaining on it will also cause a large number of germs to multiply, affecting the health of users
