Description

technical field

The utility model relates to a heat dissipation device of an air conditioner, in particular to a novel heat dissipation device of an air conditioner frequency conversion module.

Background technique

In the field of existing water source multi-connected air conditioners, the heat dissipation method of the frequency conversion module is mostly air-cooled. Due to the impact of the life of the cooling fan, it directly affects the failure rate of the air conditioner inverter module.

At the same time, the air-cooled heat sink is greatly affected by the ambient temperature; in order to meet the heat dissipation effect of the frequency conversion module, the area of the heat sink and the height of the fins must be increased, and the material cost is relatively high.

In addition, in addition to the noise of the motor, the air-cooled heat sink also has the noise of the fan, which causes great damage to the mute effect of the entire air conditioner.

Therefore, a new heat dissipation device is needed to better solve the heat dissipation problem of the water source air conditioner frequency conversion module, the noise and the cost of the heat dissipation device.

Detailed ways

In order to solve the heat dissipation problem of the frequency conversion module of the water source air conditioner, the noise and the cost of the heat dissipation device, the utility model provides a new type of heat dissipation device for the frequency conversion module of the air conditioner. Next, the new heat sink will be described in detail.

Fig. 1 shows the left view of the utility model, Fig. 2 shows the front sectional view of the utility model, Fig. 2 shows the perspective view of the utility model, as shown in Fig. 1, Fig. 2 and Fig. 3, the air conditioner frequency conversion A novel cooling device for a module, including a cooling element and a cooling driver.

The heat dissipation part includes a heat dissipation pipe 4 and a heat dissipation housing 3 with a built-in heat dissipation pipe; the heat dissipation drive part includes a frequency conversion water pump and an external pipeline; wherein, the water supply pipe and the return pipe of the external pipeline are respectively connected to the water inlet 1 of the heat dissipation pipe and the water outlet 2 to form a closed circulation pipeline, and the frequency conversion water pump drives the water in the circulation pipeline to exchange heat.

The heat dissipation tube of the heat dissipation element is made of metal material; and/or, the external pipeline of the heat dissipation drive element is made of metal material. Since there is a certain pressure in the circulation process, the water pressure must be considered when manufacturing the heat dissipation tube of the heat sink and the external pipeline of the heat dissipation drive. It must have sufficient strength to ensure that it can work safely under the maximum water pressure. . The heat dissipation pipeline can be made of iron, copper, aluminum and other metal materials with good heat dissipation effect, and at the same time, it must have sufficient strength.

The heat dissipation shell 3 of the heat dissipation element is made of metal material, such as iron, copper, aluminum and other metal materials with good heat dissipation effect.

The heat dissipation housing 3 of the heat dissipation element is in the shape of a cuboid, and since there are no usual heat dissipation fins, a more regular shape can be adopted.

The upper water pipe and the water return pipe of the above-mentioned external pipeline are respectively connected to the water inlet and water outlet of the heat dissipation pipe by screw connection or welding, and this connection method can ensure greater strength.

The radiating pipes 3 of the above-mentioned radiating elements are U-shaped tubes or scales in a circuitous shape, so as to achieve the best effect of heat exchange.

The installation surface of the air conditioner frequency conversion module is not larger than the installation surface of the heat sink. Due to the high heat dissipation efficiency of the water source, the heat dissipation device does not need to increase the area to enhance the heat dissipation effect. The heat sink only needs to be the same as or slightly larger than the installation surface of the frequency conversion module, which saves the material cost of the heat sink.

The installation surface of the frequency conversion module of the above-mentioned air conditioner and the installation surface of the heat sink are evenly coated with heat-conducting silica gel to ensure better contact and heat transfer effects.

The heat dissipation element of the heat dissipation device is fixed above the frequency conversion module of the air conditioner by screws.

The water in the above circulation pipeline directly uses the circulating water of the water source air conditioner. Directly use the circulating water of the water source air conditioner to flow in the heat dissipation pipe of the heat sink to exchange heat to cool down the frequency conversion module. Due to the low temperature of the water, the heat exchange efficiency is high, the life of the frequency conversion module is prolonged, and the frequency conversion module can work efficiently; The power consumption caused by temperature rise is reduced, and a good energy saving effect is achieved. Due to the use of water source for heat dissipation, the original cooling fan can be removed, which saves energy. At the same time, because there is no cooling fan, the noise of the motor and the fan are eliminated, which has an obvious effect on reducing the noise of the whole machine. In addition, the water circulation is stable and reliable, improving the service life of the air conditioner.

The above specific description of the utility model is intended to illustrate the implementation of specific embodiments, and should not be construed as a limitation of the utility model. Those skilled in the art can make various modifications on the basis of the detailed embodiments under the teaching of the utility model, and these variations should be included in the concept of the utility model. The scope of protection required by the utility model is only limited by the claims.
