Description

Liquid cooling converter assembly, refrigerating system and air conditioning unit

Technical Field

The utility model is used in the field of temperature regulating equipment, and particularly relates to a liquid cooling frequency converter assembly, a refrigerating system and an air conditioning unit.

Background

With the popularization of air conditioner frequency conversion technology, frequency converters play an increasingly important role in air conditioner refrigeration systems. The frequency converter can produce a large amount of heat in the in-process of operation, if can not in time arrange the heat, can lead to the reduction of frequency converter drive power ability even stop work. Therefore, how to efficiently and stably radiate heat to the frequency converter becomes a major consideration for the skilled person.

The current heat dissipation mode for the frequency converter is divided into: air cooling and liquid cooling.

1. And (3) an air cooling mode: the radiating fins are added to the rear of the main board of the frequency converter, and the surface of the radiating fins needs to be ensured to maintain a certain wind speed, for example, the required wind speed is more than or equal to 2.5m/s; if less than this wind speed, the radiator drive power capacity will decrease with decreasing wind speed.

This way of dissipating heat has the following drawbacks: 1) In order to maintain a certain wind speed on the surface of the radiator, a fan is sometimes additionally arranged for forcing air to flow on the surface of the radiator. This increases the complexity of the structure and control and increases the cost. 2) The air in the high altitude area is rarefied, and the heat dissipation performance of the air-cooled radiator can be poor under the same heat dissipation area. 3) The heat sink and the fan occupy more space.

2. Liquid cooling mode: a heat dissipation base is added behind the main board of the frequency converter, a copper pipe passes through the heat dissipation base, and liquid refrigerant flows in the copper pipe. This liquid refrigerant comes from the refrigerant at the condenser outlet in the air conditioning refrigeration system.

Because the temperature of the liquid refrigerant at the outlet of the condenser in the air-conditioning refrigerating system is about 50 ℃, the temperature can take away the heat generated by the frequency converter, thereby achieving the purpose of cooling the frequency converter. And the temperature of the refrigerant does not have the problems of condensation and the like. However, in practical applications, the evaporator and the condenser of the air conditioning system are interchanged during refrigeration and heating, that is, the condenser which performs condensation during refrigeration and heating is not the same heat exchanger. Therefore, in order to realize the liquid cooling heat dissipation, 4 one-way stop valves are added in a single refrigeration system, so that the refrigerant flowing through the copper pipe of the heat dissipation base of the heat exchanger is all from the outlet of the condenser. The design of the pipeline of the air conditioner refrigerating system is complicated, welding spots are increased, and cooling protection measures are needed to be taken when the check valves are welded, so that the production process is complicated, and the cost of 4 check valve materials per se is increased, so that the product cost of an air conditioner host manufacturer is increased, and a liquid cooling scheme is abandoned.
