Description

Technical Field

[0001] This utility model belongs to the technical field of electrical structure layout of air conditioning units, and specifically relates to a high-efficiency and energy-saving compressor inverter heat dissipation structure. Background Technology

[0002] In recent years, with the advent of the big data era, data centers have increasingly higher requirements for the stability and reliability of their air conditioning systems. To adapt to the rapid development of data centers, the power of frequency converters has also been continuously increasing, leading to the generation of a large amount of heat. If this heat cannot be dissipated in time, the frequency converter temperature will rise, affecting its performance and reliability, and even causing malfunctions, resulting in the interruption of the computer room air conditioning operation and affecting the temperature control of the computer room environment. Traditional frequency converters are mostly installed in the electrical box of the unit. In order to dissipate heat from the frequency converter, each frequency converter needs to be equipped with a corresponding cooling fan, which consumes a lot of energy. Therefore, it is necessary to develop a more energy-efficient, efficient, reliable, and easy-to-maintain heat dissipation structure to meet the heat dissipation requirements of computer room air conditioning frequency converters under different operating conditions, ensure the stable operation of the computer room air conditioning system, and provide a good operating environment for computer room equipment. Summary of the Invention

[0003] To address the high energy consumption problem of traditional frequency converters, this invention provides a high-efficiency and energy-saving heat dissipation structure for compressor frequency converters.

[0004] The high-efficiency and energy-saving compressor inverter heat dissipation structure of this utility model includes a vertical inverted triangular plate for installation at the bottom of the fan of a computer room air conditioning unit, an inverter box, an auxiliary cooling fan, and a fan duct all mounted on the inverted triangular plate. The inverter box is located on the upper part of the outer side of the inverted triangular plate, and contains an inverter. The inverter is mounted on the inverted triangular plate and has heat sinks that pass through the inverted triangular plate and extend out of the inner side. The fan duct is located on the inner side of the inverted triangular plate, and the auxiliary cooling fan is located on the lower part of the inverted triangular plate. The fan duct connects the heat sinks and the auxiliary cooling fan.

[0005] Furthermore, the ventilation duct includes a trapezoidal plate and two side plates arranged along two waists on one side of the trapezoidal plate. The side plates are attached and fixed to the inverted triangular plate, and the air duct is formed by the trapezoidal plate, the side plates, and the inverted triangular plate. In this way, the structure is simple and uses less material.

[0006] Furthermore, the auxiliary cooling fan is located inside the air duct of the fan casing. This ensures good airflow and facilitates heat dissipation.

[0007] Furthermore, a rain shield is installed on the outer surface of the inverted triangular plate above the auxiliary cooling fan to protect it from rain. This prevents rainwater from adversely affecting the auxiliary cooling fan.

[0008] Beneficial effects: The compressor inverter heat dissipation structure of this utility model can be installed at the bottom of the fan of the computer room air conditioning unit and located in the air duct of the unit. When the unit fan is running normally, the airflow of the entire unit passes through the heat sink and carries away the heat generated by the inverter during operation, thereby achieving the effect of heat dissipation for the inverter. When the unit fan is running at low speed, the airflow of the unit is insufficient to carry away all the heat generated by the inverter during operation. At this time, the auxiliary cooling fan can be driven to start working, and the airflow through the air duct can supplement the heat dissipation of the inverter's heat sink. The structure of the air duct is simple and uses less material. By placing the auxiliary cooling fan in the air duct, the airflow effect is good, which is conducive to heat dissipation. By setting up a rain shield, rainwater can be prevented from having an adverse effect on the auxiliary cooling fan. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] like Figure 1-4As shown, this utility model provides a high-efficiency and energy-saving compressor inverter heat dissipation structure, including a vertical inverted triangular plate 1 for installation at the bottom of the fan of a computer room air conditioning unit, an inverter box 2, an auxiliary cooling fan 3, and a fan duct 4, all mounted on the inverted triangular plate 1. The inverter box 2 is located on the upper part of the outer side of the inverted triangular plate 1. The inverter box 2 includes a box shell and an inverter 21 inside the box shell. Both the box shell and the inverter 21 are mounted on the inverted triangular plate 1. The inverter 21 has heat sinks 22, which pass through the inverted triangular plate 1 and extend out of the inner side of the inverted triangular plate 1. The fan duct 4 is located on the inner side of the inverted triangular plate 1, and the auxiliary cooling fan 3 is located on the lower part of the inverted triangular plate 1. Specifically, a through hole is opened on the lower part of the inverted triangular plate 1, the auxiliary cooling fan 3 is installed in the through hole, and the fan duct 4 connects the heat sink 22 and the auxiliary cooling fan 3.

[0016] The aforementioned air duct 4 includes a trapezoidal plate and two side plates arranged along two waists on one side of the trapezoidal plate. The side plates are attached and fixed to the inverted triangular plate 1. The trapezoidal plate, the side plates, and the inverted triangular plate 1 form the air duct 4. The auxiliary cooling fan 3 is located inside the air duct 4.

[0017] A rain shield 5 is provided on the outer side of the inverted triangle plate 1 above the auxiliary cooling fan 3 to protect the auxiliary cooling fan 3 from rain.

[0018] In practical use, the top of the inverted triangle plate 1 is installed at the bottom of the fan of the computer room air conditioning unit, the inverter box 2 is located on the outer side of the inverted triangle plate 1, and the heat sink 22 is located on the inner side of the inverted triangle plate 1, i.e., in the air duct of the unit fan. When the computer room air conditioning unit is running normally, it can dissipate heat by means of the ventilation it generates. When the speed of the computer room air conditioning unit is low, it can also dissipate heat through its own auxiliary cooling fan 3 and air duct 4, thereby removing the heat from the heat sink and reducing the temperature of the heat sink, which can greatly save energy consumption.

[0019] Unless otherwise specified, all technologies mentioned above refer to existing technologies.

[0020] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification.
