BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to a separable liquid-cooling heat-dissipation module, which provides a modular structure formed by combining a plurality of heat conduction blocks in combination with pipelines, so as to eliminate a disorderly state of pipelines and achieve the effects of heat-dissipation and energy-saving.

2. Related Art

In recent years, the heat dissipation problem for computers is always an important issue, especially for servers. Common heat-dissipation methods include a gas-cooling mode and a liquid-cooling mode.

In the gas-cooling heat dissipation mode, heat-sink fin groups are adhered to electronic components that need heat dissipation, for example, a central processing unit (CPU) or a memory. Then, heat energy generated by the electronic components is conducted to the heat-sink fin groups. Then, heat-sink fans blow the heats to the open air, thereby achieving the effect of heat dissipation.

In the liquid-cooling heat dissipation mode, a heat conduction block is adhered to electronic components that need heat dissipation and has a water channel, in which the water channel is respectively connected to a water flow-in pipe and a water flow-out pipe. Heat energy generated by the electronic components is conducted to the heat conduction block, and a coolant enters the heat conduction block via the water flow-in pipe, and then leaves the heat conduction block via the water flow-out pipe, thereby taking the heat energy away and achieving the heat dissipation effect.

Both the above two heat dissipation modes can achieve the heat dissipation effect and the two modes have their respective defects. The gas-cooling heat dissipation mode mainly relies on heat-sink fans, but the heat-sink fans produce a lot of noises during operation, and a high cost is required for solving the noise problem. Thus, the gas-cooling heat dissipation mode is restricted by the equipment cost problem and the noise problem. In addition, the heat-sink fans consume a lot of electric energy during operation.

The liquid-cooling heat dissipation mode mainly uses a coolant. However, the current devices adopting the liquid-cooling heat dissipation mode can only be used for a single electronic component. If a plurality of electronic components requires heat dissipation, a plurality of groups of devices needs to be installed, resulting in disorderly pipelines within the computer or server, and even worse, the problem of coolant leakage may probably occur.

To sum up, the common gas-cooling heat dissipation mode and liquid-cooling heat dissipation mode respectively have the above defects, so that the existing heat dissipation modes further need to be improved to a large extent.

SUMMARY OF THE INVENTION

In view of the above defects, the present invention is directed to a separable liquid-cooling heat-dissipation module, in which a plurality of heat conduction blocks and pipelines are modularized, so as to eliminate a disorderly state of pipelines and avoid a problem of coolant leakage caused by disorderly pipelines. In addition, phase state conversion of a refrigerant is used to realize automatic cycling of the refrigerant, thereby achieving the effects of heat-dissipation and energy-saving.

In order to achieve the above objective, the present invention provides a separable liquid-cooling heat-dissipation module, which comprises a first flow pipe, a second flow pipe, and a plurality of heat conduction blocks. The first flow pipe has a first flow channel and a plurality of flow-out holes. The flow-out holes are respectively located at two sides of the first flow pipe, and are communicated with the first flow channel. The first flow pipe has a gap at a bottom end. The second flow pipe is set on a top end of the first flow pipe and has a gap at a bottom end. The second flow pipe has a second flow channel and a plurality of flow-in holes. The flow-in holes are communicated with the second flow channel, and are respectively located at two sides of the second flow pipe. Each heat conduction block has a water channel respectively connected to an inlet pipe and an outlet pipe. The other end of each inlet pipe is connected to the corresponding flow-out hole, and the other end of each outlet pipe is connected to the corresponding flow-in hole.

An end of the first flow pipe is connected to a flow-in pipe communicated with the first flow channel. An end of the second flow pipe is connected to a flow-out pipe communicated with the second flow channel. The other end of the flow-in pipe and the other end of the flow-out pipe are connected with a quick coupler. The quick coupler has a flow-in hole and a flow-out hole, in which the flow-in hole is connected to the flow-in pipe, and the flow-out hole is connected to the flow-out pipe. An end of the first flow pipe and an end of the second flow pipe are disposed with a seal plate, and a leak proof washer is respectively disposed between the seal plate and the first flow pipe and the second flow pipe.

A hole sectional area of the second flow channel is approximately twice as much as a pipe sectional area of the outlet pipe, the pipe sectional area of the outlet pipe is larger than that of the inlet pipe, and the hole sectional area of the second flow channel equals that of the first flow channel.

Each heat conduction block has a through hole respectively located at two opposite angles. Each through hole is disposed with a fixture, and the fixture has an elastomer.

With the above structure, each heat conduction block may be disposed at an electronic component which needs heat dissipation within a server. A liquid-state refrigerant at a low temperature sequentially flows into the first flow channel and the water channel from the flow-in pipe, and absorbs heat energy generated by the electronic components, so as to realize heat dissipation for the electronic components. Thus, the liquid-state refrigerant at a low temperature is converted into gas-state refrigerant at a high temperature, which passes through the second flow channel and the flow-out pipe, and leaves the second flow pipe, and is converted back to the liquid-state refrigerant at a low temperature.

Through the phase state conversion, the refrigerant produces an automatic cycling effect, so as to realize effects of heat-dissipation and energy-saving. In addition, with the structure combined by a plurality of heat conduction blocks with the first flow pipe and the second flow pipe, the liquid-cooling heat dissipation device modularized, thereby reducing the number of pipelines to be configured within the server for cooling, eliminating a disorderly state of pipelines, and preventing a possible problem of coolant leakage caused by pipelines.

Furthermore, the gap of the second flow pipe forms an isolating and heat-insulating structure between the first flow pipe and the second flow pipe, so that the influences on the liquid-state refrigerant at a low temperature flowing in the first flow pipe caused by the gas-state refrigerant at a high temperature flowing in the second flow pipe are reduced to the minimum level, so that the liquid-state refrigerant at a low temperature can achieve an optimal heat-dissipation effect.

DETAILED DESCRIPTION OF THE INVENTION

The implementation of the present invention is described below through specific embodiments, and those skilled in the art can easily understand other advantages and efficacy of the present invention based on the disclosure of the specification.

Referring toFIG. 1andFIG. 2, a separable liquid-cooling heat-dissipation module of the present invention has a first flow pipe1, a second flow pipe2, a plurality of heat conduction blocks3, and a quick coupler4.

The first flow pipe1has a first flow channel10, and a plurality of flow-out holes11respectively at two sides of the first flow pipe1. The flow-out holes11are communicated with the first flow channel10. An end of the first flow pipe1is connected with a flow-in pipe12, and the other end has two fixing holes13. The first flow pipe1has a gap14at a bottom end. In addition, the flow-in pipe12is communicated with the first flow channel10.

The second flow pipe2is set on a top end of the first flow pipe1and has a second flow channel20, and a plurality of flow-in holes21are respectively located at two sides of the second flow pipe2. The flow-in holes21are communicated with the second flow channel20. An end portion of an end of the second flow pipe2has two fixing holes23, and the other end is connected with a flow-out pipe22. A gap24is formed between the second flow pipe2and the first flow pipe1, so as to reduce a contact area between the second flow pipe2and the first flow pipe1and form an isolating and heat-insulating structure. In addition, the flow-out pipe22is communicated with the second flow channel20.

A seal plate5is disposed at positions of the first flow pipe1and the second flow pipe2having the fixing holes13and23. A plurality of fixtures50passes through the seal plate5, and is screwed at the fixing holes13and23, so that the seal plate5is fixed at end portions of the first flow pipe1and the second flow pipe2. A leak proof washer51is respectively disposed between the seal plate5and the first flow pipe1and the second flow pipe2, so as to prevent the leakage phenomenon between the first flow channel10and the second flow channel20.

Each heat conduction block3has a water channel30respectively connected to an inlet pipe31and an outlet pipe32. The other end of each inlet pipe31is connected to the corresponding flow-out hole11, and the other end of each outlet pipe32is connected to the corresponding flow-in hole21. Each heat conduction block3has a through hole33respectively located at two opposite angles. Each through hole33is disposed with a fixture34, and the fixture34has an elastomer35. The elastomer35may be a spring. A cross-sectional area of the inlet pipe31is smaller than that of the outlet pipe32, and the cross-sectional area of the outlet pipe32is smaller than a cross-sectional area of the second flow channel20, and the cross-sectional area of the second flow channel20equals that of the first flow channel10.

The quick coupler4has a flow-in hole40and a flow-out hole41. The flow-in hole40is connected to the flow-in pipe12, and the flow-out hole41is connected to the flow-out pipe22.

Referring toFIG. 3, a server6has a plurality of electronic components which need heat dissipation therein. Each heat conduction block3is disposed at a position corresponding to the electronic component. An end of each fixture34is fastened within the server6. Each elastomer35forces the heat conduction block3to be further closely adhered to the electronic component.

The quick coupler4is connected to a refrigerant source60. A liquid-state refrigerant at a low temperature coming from the refrigerant source60sequentially passes through the flow-in hole40and the flow-in pipe12, enters the first flow channel10, and then passes through the flow-out holes11and the inlet pipe31, and enters the water channel30.

The heat energy generated by the electronic components during operation is conducted to the heat conduction blocks3, and the liquid-state refrigerant at a low temperature within the water channel30absorbs the heat energy, so as to realize an objective of heat dissipation for the electronic components. Then, after absorbing the heat energy, the liquid-state refrigerant at a low temperature is converted into gas-state refrigerant at a high temperature.

The gas-state refrigerant at a high temperature passes through the outlet pipes32and the flow-in holes21, enters the second flow channel20, and then returns to the refrigerant source60via the flow-out pipe22, so as to be converted back to the liquid-state refrigerant at a low temperature. When the gas-state refrigerant at a high temperature passes within the second flow channel20, the gap24reduces a contact area between the second flow pipe2and the first flow pipe1, so that the gap24forms an isolating and heat-insulating structure. Thus, the gas-state refrigerant at a high temperature produces no influence on the liquid-state refrigerant at a low temperature flowing within the first flow channel10, so that the liquid-state refrigerant at a low temperature can achieve the expected heat dissipation effects.

The above differences in cross-sectional area ensure easy flowing of the gas-state refrigerant to, and ensure that the pressure generated by the refrigerant during phase state conversion has a buffering space. Thus, through the phase state conversion, the refrigerant generates an automatic cycling effect, thereby achieving the heat-dissipation and energy-saving effects.

Furthermore, by using the quick coupler4, the present invention can be quickly connected to or disconnected from the refrigerant source60, so that the present invention also has conveniences in assembling and disassembling.
