Server cabinet and phase-change thermoelectric composite heat dissipation system thereof

Abstract

The invention discloses a phase-change thermoelectric composite heat dissipation system. The system comprises a cabinet body, a phase change heat dissipation mechanism and a thermoelectric heat dissipation mechanism. The phase change heat dissipation mechanism is arranged on the cabinet body and is used for carrying out heat dissipation on the cabinet body in a refrigerant phase change refrigeration mode, and the thermoelectric heat dissipation mechanism is arranged on the cabinet body and is used for carrying out forced heat dissipation on a condensation end of the phase change heat dissipation mechanism in a thermoelectric refrigeration mode. Thus, the cabinet body is cooled through the change of the refrigerant medium state of the phase change cooling mechanism; and meanwhile, the condensation end of the phase change heat dissipation mechanism is subjected to forced heat dissipation in a thermoelectric refrigeration mode through the electric heat dissipation mechanism, continuous and stable operation of the phase change heat dissipation mechanism is guaranteed, the heat dissipation efficiency can be greatly improved through combined use of the two heat dissipation modes, and thehigh heat dissipation performance is guaranteed. Compared with the prior art, on the basis that the heat dissipation performance of the server cabinet is guaranteed, the requirement for the operationenvironment is lowered, the operation noise is lowered, and the arrangement cost is reduced. The invention also discloses a server cabinet, and the beneficial effects of the server cabinet are as described above.

Description

Technical field [0001] The invention relates to the technical field of servers, in particular to a phase-change thermoelectric composite heat dissipation system. The invention also relates to a server cabinet. Background technique [0002] With the development and implementation of technologies such as edge computing and 5G, the application of small-scale, decentralized micro data centers has become more and more extensive. Data centers mainly include server cabinets and several servers integrated in the cabinets. [0003] At present, this type of data center mainly has two forms in application, including: [0004] 1. Contains the form of air conditioning unit. This type of data center is an integrated product that inherits rack-mounted air conditioners or inter-row air conditioners, and is designed with closed aisles. This form has the following characteristics: a. It is a complete system and does not depend on the external environment; b. It can be designed as a fully enclosed c...

AI Technical Summary

Problems solved by technology

This is a data center that does not include a cooling system. It is characterized by the fact that the front and rear doors of the cabinet are all mesh doors, relying on the cooling capacity of the deployment environment to dissipate heat from the server. The advantage is that it can be used out of the box, and the disadvantage is that it is harmful to the environment. It is highly dependent and cannot be deployed in an environment with a lot of dust

Moreover, the noise of equipment such as servers is relatively high during operation, so it cannot be deployed in an office environment.

[0006] Small-scale, dispersedly deployed micro-data centers are more and more widely used. A large part of the application scenarios of such data centers are in office areas, industrial plants and other environments. The characteristics of these two types of environments are that they can ensure that the ambient temperature The stability of the environment, and there is a high requirement for the noise level (office environment), the cleanliness of the air cannot be guaranteed (factory environment)

In the above environment, if there is a need for rapid and decentralized deployment, the two product forms in the prior art cannot meet the requirements
