Cooling distribution device

Abstract

This application relates to the field of thermal management technology for data centers, and more particularly to a cooling distribution device. The cooling distribution device includes a housing and a cooling distribution assembly. The housing has an installation cavity and a maintenance passage. The installation cavity and the maintenance passage are distributed and connected along a first horizontal direction of the cooling distribution device. The opposite ends of the maintenance passage extend along a second horizontal direction of the cooling distribution device to opposite sides within the housing. The cooling distribution assembly is at least partially located in the installation cavity and at least partially located outside the maintenance passage. The housing includes a maintenance door located at one end of the maintenance passage. The maintenance door can be opened, opening the maintenance passage and allowing maintenance personnel to enter the maintenance passage to perform maintenance on the cooling distribution device, which facilitates flexible arrangement of the cooling distribution device.

Claims

1. A cooling distribution device for providing a cooling medium to the built-in liquid cooling pipeline of a server, wherein, The cooling distribution device includes a housing and a cooling distribution apparatus. The housing has an installation cavity and a maintenance channel. The installation cavity and the maintenance channel are distributed and connected along a first horizontal direction of the cooling distribution device. The opposite ends of the maintenance channel extend along a second horizontal direction of the cooling distribution device to opposite sides of the housing. The cooling distribution apparatus is at least partially located in the installation cavity and at least partially located outside the maintenance channel. The housing includes a maintenance door located at one end of the maintenance channel. The maintenance door can be opened to open the maintenance channel. The second horizontal direction is different from the first horizontal direction.

2. The cooling distribution device as described in claim 1, wherein, The first horizontal direction is the left-right direction of the cooling distribution device, and the second horizontal direction is the front-back direction of the cooling distribution device; or, the first horizontal direction is the front-back direction of the cooling distribution device, and the second horizontal direction is the left-right direction of the cooling distribution device.

3. The cooling distribution device as described in claim 1, wherein, The width of the maintenance passage along the first horizontal direction is 20%-30% of the width of the cooling distribution equipment along the first horizontal direction.

4. The cooling distribution device as described in claim 1, wherein, The maintenance door is equipped with a control box that rotates with the maintenance door. The control box is electrically connected to the cooling distribution device. When the maintenance door closes the maintenance passage, the control box is at least partially located within the maintenance passage.

5. The cooling distribution device as described in claim 4, wherein, The control box includes a box body and a box door. The box body is located inside the maintenance door body, and the box door is hinged to the maintenance door body. The box door and the maintenance door body can rotate relative to each other.

6. The cooling distribution apparatus as described in claim 1, wherein, The cooling distribution device includes a primary side loop, a secondary side loop, and a heat exchanger. Both the primary side loop and the secondary side loop pass through the heat exchanger. The primary side loop is connected to an external cold source, and the secondary side loop is connected to the built-in liquid cooling pipeline of the server. The heat exchanger realizes heat exchange between the primary side loop and the secondary side loop, and the heat exchanger is arranged close to the maintenance passage.

7. The cooling distribution device as described in claim 6, wherein, The primary side circuit includes a primary side inlet pipe, a primary side outlet pipe, and a replenishment pipe. The heat exchanger is located between the primary side inlet pipe and the primary side outlet pipe. The replenishment pipe is connected to the primary side inlet pipe and provides the cooling medium to the primary side inlet pipe. The primary side inlet pipe, the primary side outlet pipe, and the replenishment pipe are all connected to the heat exchanger from one side away from the maintenance passage.

8. The cooling distribution device as described in claim 6, wherein, The secondary side circuit includes a secondary side inlet pipe and a secondary side outlet pipe. The heat exchanger is located between the secondary side inlet pipe and the secondary side outlet pipe. The secondary side outlet pipe is connected to a circulation pump. The circulation pump is used to drive the cold medium in the secondary side inlet pipe through the heat exchanger into the secondary side outlet pipe. The circulation pump is arranged close to the maintenance passage.

9. The cooling distribution device as described in claim 8, wherein, The circulating pump is provided in multiple sets, and the multiple sets of circulating pumps are connected in parallel to the secondary side outlet pipeline.

10. The cooling distribution device as described in claim 6, wherein, The secondary side circuit is also connected to an expansion tank, which is located near the maintenance passage and above the heat exchanger.
