Description

Technical Field

[0001] This utility model relates to a heat dissipation cabinet, and more particularly to a modular liquid-cooled heat dissipation cabinet that constitutes a modular and integrated closed-loop liquid cooling circulation heat dissipation structure. Background Technology

[0002] With the increasing demand for artificial intelligence training, big data analysis, cloud computing, and high-performance computing, data center servers consume a considerable amount of power. Traditional air cooling is no longer sufficient to meet the cooling needs of such high-power servers because air cooling is inefficient and requires a large number of fans and air conditioning units, resulting in high energy consumption. Therefore, liquid cooling is gradually replacing traditional air cooling, which can more efficiently remove heat from the server's heat-generating components and extend the equipment's lifespan.

[0003] Current liquid chiller cabinet designs, which include heat exchangers and coolant supply via external chillers and CDUs (Cooling Distribution Units), have at least the following disadvantages:

[0004] 1. The wiring and installation are complex, requiring long-distance pipelines, which increases construction costs.

[0005] 2. CDUs need to be placed independently in the data center, occupying a large amount of data center space. This is not conducive to the deployment of high-density server clusters.

[0006] 3. Chillers and CDUs are expensive and require regular maintenance, resulting in high overall setup and maintenance costs.

[0007] 4. The cooling capacity of an external CDU or chiller needs to be transferred through long pipelines, resulting in temperature delay and efficiency loss. For instantaneous high power consumption, the response speed is insufficient.

[0008] 5. If the CDU or chiller fails, it will affect the cooling capacity of the entire computer room, and the lack of modular structure is not conducive to small-scale construction or expansion.

[0009] 6. Most only provide fixed coolant flow and temperature settings, lacking dynamic adjustment, and the host cannot collect energy consumption and carbon footprint data in real time. Utility Model Content

[0010] In view of the above, the purpose of this utility model is to provide a modular liquid-cooled heat dissipation cabinet that constitutes a modular and integrated closed-loop liquid-cooled heat dissipation structure.

[0011] To achieve the above objectives, this utility model provides a modular liquid-cooled heat dissipation cabinet, comprising a cabinet body, a transmission unit, a return water pipe, and a condensation unit. The cabinet body has an internal accommodating space for housing a heat source device. The cabinet body includes at least one heat exchange unit for cooling and dissipating heat from the heat source device using coolant. The transmission unit is movably disposed within the accommodating space of the cabinet body. The transmission unit includes a water tank and at least one pump. The water tank is connected to an inlet pipe for introducing coolant into the water tank. The pump is connected to the water tank and an outlet pipe, which is connected to the heat exchange unit. The system uses a pump to draw coolant from the water tank and output it through the outlet pipe, thereby delivering the coolant to the heat exchange unit. The return pipe connects to the heat exchange unit to receive the coolant that has been heated after heat exchange. The condenser unit has an input end connected to the return pipe and an output end connected to the inlet pipe to return the cooled coolant output from the return pipe to the condenser unit. The condenser unit can cool and reduce the temperature of the cooled coolant and output it to the inlet pipe. The heat exchange unit, the transmission unit, the return pipe, and the condenser unit constitute a coolant circulation loop structure.

[0012] The cabinet is further equipped with a movable electrical control unit, which includes a power input terminal, a power switch, a cooling fan, a plurality of power line interfaces, and a plurality of signal line interfaces. The cooling fan is used to exhaust the heat inside the electrical control unit to perform a cooling function. The plurality of power line interfaces and the plurality of signal line interfaces are used to connect to the transmission unit, the condensation unit, or an environmental control host via power lines and signal lines to provide power and perform signal transmission.

[0013] The electronic control unit is connected to a plurality of sensors to sense the coolant temperature and flow rate. The electronic control unit is connected to an artificial intelligence platform, which adjusts the coolant temperature and flow rate based on real-time data of the coolant temperature and flow rate.

[0014] The water tank is connected to an expansion tank, an exhaust end, a water supply pipe, and a drain pipe, and the water supply pipe has a water supply pump.

[0015] The output end of the condenser unit is connected to the inlet pipe via a cold water outlet pipe, and the input end of the condenser unit is connected to the return pipe via a hot water return pipe. The cold water outlet pipe and the hot water return pipe are selected from flexible hoses and have quick-connect structures at both ends to connect to the inlet pipe and the return pipe.

[0016] The heat exchange unit is configured in multiple ways. The cabinet is further configured with a piping unit. The piping unit is constructed such that the outlet water pipe is connected to the multiple heat exchange units through an inlet water manifold valve and several inlet water manifolds, and the return water pipe is connected to the multiple heat exchange units through a return water manifold valve and several return water manifolds.

[0017] The cabinet can be connected in parallel with multiple cabinets through the condensation unit to form a liquid-cooled cabinet group.

[0018] It further includes an ESG data collection module for collecting data on energy consumption, water use and carbon emissions, and transmitting the collected data to an external environmental control host or an ESG platform server for immutable decentralized storage and visualization analysis via blockchain technology.

[0019] The transmission unit has a handle on its surface for hand gripping and operation, facilitating its installation, replacement, and maintenance.

[0020] The cabinet is equipped with a door and an electronic lock for opening and closing control and to enhance security. The cabinet also has a remote control module that connects to a remote control platform via a network communication interface for monitoring the operating parameters of the coolant circulation loop, controlling start and stop, and providing feedback on abnormal conditions.

[0021] This invention constitutes a modular and integrated closed-loop liquid cooling circulation heat dissipation structure, which carries away the heat generated by the operation of the heat source equipment through the circulation of coolant and performs high-efficiency heat dissipation.

[0022] Modular construction enhances installation flexibility, allowing for the replacement of different drive units to suit different heat loads. It integrates conventional technologies such as CDU and chiller, directly supplying coolant with a suitable temperature range, such as approximately 7°C to 25°C. This can precisely match the heat dissipation needs of heat source equipment and prevent condensation. It eliminates the need for long-distance piping, reduces costs, avoids the risk of leakage, reduces space occupation, and avoids temperature delay and efficiency loss.
