Abstract

A device may include: a frame having an interior; an electronic component; a heat conducting body in thermal contact with the electronic component; a conduit containing a liquid coolant, the conduit being coupled to the heat conducting body to deliver the liquid coolant to and from the heat conducting body; and a pump positioned within the interior of the frame, the pump being removably insertable into the interior of the frame and being removably couplable to the conduit to circulate the liquid coolant through the conduit.

First claim

1 . A device comprising:
a frame comprising: a first end, a second end, a bottom surface, a first side wall and a second side wall extending between the first end and the second end, and an interior; a first pump drawer and a second pump drawer positioned within the interior of the frame, the first pump drawer positioned above the second pump drawer, relative to the bottom surface of the frame and along the first side wall of the frame; and a first pump positioned within the first pump drawer and a second pump positioned within the second pump drawer, the first pump and the second pump being removably coupled to a conduit using a plurality of dripless blind-mate connectors; wherein each of the first pump drawer with the first pump and the second pump drawer with the second pump is replaceable without terminating the operation of the device.

2 . The device of claim 1 , comprising a plurality of fans positioned at the first end of the frame between the first side wall and the second side wall, the fans to introduce an airflow into the interior of the frame, wherein the first pump drawer and the second pump drawer are positioned in front of a fan of the plurality of fans.

3 . The device of claim 2 , wherein each of the first pump drawer and the second pump drawer tapers towards the first side wall of the frame in a direction towards the first end of the frame comprising the fans.

4 . The device of claim 2 , wherein a fan of the plurality of fans that is positioned adjacent to the first side wall is removably received within a fan receptacle, the fan being replaceable without terminating the operation of the device, and wherein each of the first pump drawer with the first pump and the second pump drawer with the second pump is replaceable through the fan receptacle.

5 . The device of claim 2 , wherein a width of the first pump drawer and the second pump drawer is smaller than a width of a fan of the plurality of fans that is positioned adjacent to the first side wall of the frame.

6 . The device of claim 2 , wherein the first pump drawer and the second pump drawer partly interfere with the airflow into the interior of the frame provided by a fan of the plurality of fans that is positioned adjacent to the first side wall of the frame.

7 . The device of claim 1 , wherein the first pump and the second pump operate simultaneously.

8 . The device of claim 1 , wherein the first pump operates, and the second pump a is activated if a rotational speed of the first pump reduces below a predefined threshold.

9 . The device of claim 1 , comprising a controller to control the first pump and the second pump to maintain a desired flow rate of the liquid coolant through the conduit.

10 . The device of claim 9 , wherein the controller is a central processing unit of the device.

11 . The device of claim 1 , comprising a heat sink positioned within the interior of the frame, wherein a portion of the conduit passes through the heat sink, the heat sink to cause heat to dissipate from the liquid coolant through the portion of the conduit passing through the heat sink to cool the liquid coolant.

12 . The device of claim 1 , comprising:
an electronic component positioned in the interior of the frame, a cooling body in thermal contact with the electronic component, the cooling body being coupled to the conduit to deliver a liquid coolant to and from the cooling body.

13 . A device comprising:
a frame comprising an interior; a cooling body positioned in the interior of the frame; a conduit containing a liquid coolant, the conduit being coupled to the cooling body; and a pump removably coupled to the conduit using a plurality of dripless connectors, the pump being positioned within the interior of the frame along a side wall of the frame, the pump being replaceable without terminating the operation of the device.

14 . The device of claim 13 , comprising a plurality of fans positioned at one end of the frame.

15 . The device of claim 14 , wherein a fan of the plurality of fans that is positioned adjacent to the side wall of the frame is removably received within a fan receptacle, the fan being replaceable without terminating the operation of the device.

16 . The device of claim 15 , wherein the pump is replaceable through the fan receptacle.

17 . The device of claim 14 , wherein a width of the pump is smaller than a width of a fan of the plurality of fans that is positioned adjacent to the side wall of the frame.

18 . The device of claim 14 , wherein the pump partly interferes with an airflow into the interior of the frame provided by a fan of the plurality of fans that is positioned adjacent to the side wall of the frame.

19 . The device of claim 18 , wherein the pump is supported within a pump drawer, the pump drawer extending along the side wall of the frame.

20 . The device of claim 19 , wherein the pump drawer tapers towards the side wall of the frame in a direction towards an end of the frame comprising a plurality of fans.
