Problems solved by technology

The first method mentioned above is only redundant for the pump. Once the heat exchanger in the CDU fails, the entire system will be in a state of paralysis
The second method requires the purchase of two CDUs, which is costly and takes up a lot of space, which will reduce the deployment density of server cabinets

Embodiment Construction

[0030] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding and should be considered as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted from the following description for clarity and conciseness.

[0031] In the existing CDU redundancy technical solutions, only the liquid conveying device (such as a pump) is redundant, which cannot cope with the failure of the heat exchanger; or two CDUs are used as backups for each other, which will increase the cost and occupy the larger space. In view of the above defects, in the embodiment of the present invention, a single CDU can ...

Abstract

The invention discloses a cold liquid heat exchange system and a liquid cooling system, and relates to the technical field of liquid cooling. A specific embodiment of the cold liquid heat exchange system includes: a first heat exchange device, a second heat exchange device, a first liquid conveying device and a second liquid conveying device; wherein, the liquid provided on the cooling side can pass through the first heat exchange device. The heating device returns to the cooling side; the liquid provided on the cooling side can be returned to the cooling side through the second heat exchange device; the liquid output from the heat-dissipating side can pass through the first liquid conveying device and the first heat exchange device in turn and return to the cooling side. Radiation side; the liquid output from the side to be radiated can return to the side to be radiated through the first liquid conveying device and the second heat exchange device in sequence; the liquid output from the side to be radiated can be returned to the side through the second liquid conveying device and the first heat exchange device in sequence. to the side to be radiated; the liquid output from the side to be radiated can be returned to the side to be radiated through the second liquid conveying device and the second heat exchange device in sequence. This embodiment enables the cold-liquid heat exchange system to realize a highly reliable redundant function.

Description

technical field [0001] The invention relates to the technical field of liquid cooling, in particular to a cold liquid heat exchange system and a liquid cooling system. Background technique [0002] In the existing cooling capacity distribution unit CDU (Chill water Distribution Unit) of the liquid cooling system of the data center, in order to realize the redundant function, a double pump design of the main pump plus a backup pump is usually adopted, or two CDUs are used as backup for each other. The first method mentioned above is only for redundancy of the pump. Once the heat exchanger in the CDU fails, the entire system is in a state of paralysis. The second method requires the purchase of two CDUs, which is costly and occupies a large space, which will reduce the deployment density of server cabinets. SUMMARY OF THE INVENTION [0003] In view of this, the embodiments of the present invention provide a cold liquid heat exchange system and a liquid cooling system, where...
