Description

Technical Field

[0001] This utility model relates to a heat dissipation device, and more particularly to a cooling system. Background Technology

[0002] For devices such as server hosts that operate at extremely high temperatures, heat dissipation mechanisms must be considered during the design phase. Commonly used heat dissipation devices include power plate heat exchangers (PHE) and refrigerants (RAD). While power plate heat exchangers offer superior cooling performance, the necessary cooling fluid circulation loop occupies considerable space, making them less economical unless high-efficiency cooling is required. Refrigerants, on the other hand, primarily work with fan-driven airflow, achieving cooling through heat conduction and convection. They offer advantages such as a larger heat dissipation area and easier installation, but their cooling efficiency is not as high as that of power plate heat exchangers.

[0003] Considering the current operation of server hosts, whether high-density processing is performed will affect the waste heat generated during operation, which in turn will directly affect the required cooling performance. In other words, server hosts may require different cooling mechanisms at different times. Therefore, the aforementioned water-cooled plate heat exchangers and radiators each have their advantages and disadvantages, and may provide a better cooling solution at specific times. If the two cooling mechanisms can be properly integrated, their respective advantages can be leveraged to meet a wider range of cooling needs. Utility Model Content

[0004] The purpose of this invention is to provide a cooling system that can properly integrate two or more heat dissipation mechanisms.

[0005] This utility model relates to a cooling system suitable for connecting an operating unit, the operating unit including a server and two heat dissipation pipes connected in parallel to each other, forming a primary side and a secondary side respectively. The cooling system includes a water-cooled plate unit, a radiator unit connected to the water-cooled plate unit, and a control unit connected to the water-cooled plate unit and the radiator unit.

[0006] The water-cooled plate unit includes a plate heat exchanger connected to the heat dissipation side between the primary side and the secondary side, a first circulation loop of the heat dissipation pipe connected to the primary side, and a cooling water source connected to the first circulation loop.

[0007] The radiator unit includes a liquid-gas heat exchanger connected to the plate heat exchanger of the water-cooled plate unit via the heat dissipation pipes on the secondary side, an air-cooling module spaced apart from the liquid-gas heat exchanger, a second circulation loop connected between the heat dissipation pipes on the secondary side and the first circulation loop, a heat dissipation water source connected to the second circulation loop and used to provide heat dissipation water, and a circulating water pump disposed in the second circulation loop.

[0008] The cooling system of this utility model has at least one fan mechanism in the air-cooled module of the radiator unit.

[0009] The cooling system of this utility model has an air-cooling module having a plurality of fan mechanisms arranged in a longitudinal and transverse pattern.

[0011] The cooling system of this utility model further includes a temperature detector configured in the second circulation loop for detecting the water temperature information of the cooling water in the radiator unit.

[0012] The cooling system of this utility model includes a control unit for controlling the operation of the water-cooled plate unit and the radiator unit to dissipate heat from the operating unit, and for activating the water-cooled plate unit when the water temperature information is higher than the default value.

[0014] The cooling system of this utility model includes a control unit comprising a judgment module disposed on the radiator unit.

[0015] The beneficial effects of this utility model are as follows: it integrates the two heat dissipation mechanisms of the water-cooled plate unit and the radiator unit, which can be switched and selected according to different heat dissipation needs. Furthermore, the control unit can simultaneously activate the water-cooled plate unit and the radiator unit when necessary to cope with the high load operation of the operating unit, thereby forming a backup mechanism and providing more diversified heat dissipation modes.

[0019] See Figure 1 This invention relates to an embodiment of a cooling system, applicable to a connected operating unit 1. The operating unit 1 includes a server 11 and two parallel heat dissipation pipes 12 forming a primary side 101 and a secondary side 102, respectively. See also... Figure 1 and Figure 2 This embodiment includes a water-cooled plate unit 2, a heat sink unit 3 connected to the water-cooled plate unit 2, and a control unit 4 connected to the water-cooled plate unit 2 and the heat sink unit 3. It should be noted that although this embodiment describes the operating unit 1 as a data server host, in actual operation, the form of the operating unit 1 is not limited, as long as it can be supplied with coolant (in this embodiment, cooling water is used as an example) to form one of the heat dissipation mechanisms.

[0020] The water-cooled plate unit 2 includes a plate heat exchanger 21 with a heat dissipation side 103 connected between the primary side 101 and the secondary side 102, a first circulation loop 22 connected to the heat dissipation pipe 12 of the primary side 101, and a cooling water source 23 connected to the first circulation loop 22. The water-cooled plate unit 2 utilizes a heat conduction mechanism, using the heat absorption effect of the coolant to remove heat energy from the heat dissipation side 103 of the operating unit 1. Then, through the connection between the first circulation loop 22 and the heat dissipation pipe 12 of the primary side 101, a heat dissipation cycle is formed by introducing the cooling water source 23, and finally, the heat dissipation effect is achieved through the plate heat exchanger 21.

[0021] The radiator unit 3 includes a liquid-gas heat exchanger 31 connected to the plate heat exchanger 21 via the heat dissipation pipe 12 on the secondary side 102; an air-cooling module 32 spaced apart from the liquid-gas heat exchanger 31; a second circulation loop 33 connected between the heat dissipation pipe 12 on the secondary side 102 and the first circulation loop 22; a heat dissipation water source 34 connected to the second circulation loop 33 and used to provide heat dissipation water; a circulating water pump 35 disposed in the second circulation loop 33; and a temperature detector 36 disposed in the second circulation loop 33 and used to detect the water temperature information of the heat dissipation water. Through the interconnected flow path configuration of the first circulation loop 22 and the second circulation loop 33, the coolant can circulate and conduct within them, achieving proper integration of the water-cooled plate unit 2 and the radiator unit 3. The heat energy absorbed by the coolant in the radiator unit 3 is exchanged in the liquid-gas heat exchanger 31 through a heat absorption and release mechanism involving the phase change of liquid and gas. Subsequently, the heat can be dissipated by the airflow from the air-cooling module 32.

[0022] The air-cooling module 32 has multiple fan mechanisms 321 arranged longitudinally and laterally. The specifications of the fan mechanisms 321 can be selected according to the heat dissipation requirements, and the number of fan mechanisms can be considered to meet the heat dissipation needs of the liquid-gas heat exchanger 31. In other embodiments, the air-cooling module 32 has at least one blower. That is, the air-cooling module 32 can also be configured with a blower to meet the requirements or cooperate with other environmental conditions to achieve the required heat dissipation effect.

[0023] See Figure 3 The control unit 4 includes two judgment modules 41 respectively disposed on the water-cooled plate unit 2 and the heat sink unit 3, which can be used to confirm whether the water-cooled plate unit 2 and the heat sink unit 3 are operating normally. Specifically, the control unit 4 can be a control chip that has pre-written control rules and issues control commands for the operation of the water-cooled plate unit 2 and the heat sink unit 3 after processing specific parameters.

[0024] Further reference Figure 1 , 2For example, depending on the actual operation of the server 11 in the operating unit 1, when faster, real-time heat dissipation is needed, the radiator unit 3 can be used for heat dissipation first. Furthermore, since the water-cooled plate unit 2 does not need to be activated, heat dissipation can be achieved in a relatively energy-efficient manner. At this time, the temperature sensor 36 continuously monitors the temperature of the cooling water to determine whether the radiator unit 3 is sufficient to meet the heat dissipation requirements. If the temperature of the cooling water, i.e., the water temperature information, is higher than a default value, it indicates that the server 11 is operating under high load and the temperature is high. In this case, the water-cooled plate unit 2 can be activated, and both the water-cooled plate unit 2 and the radiator unit 3 can be connected in parallel for heat dissipation, thereby improving heat dissipation efficiency and meeting the demand.

[0025] Furthermore, if the radiator unit 3 is used solely for heat dissipation, and the judgment module 41 corresponding to the radiator unit 3 determines that the radiator unit 3 is not operating normally, the control unit 4 will activate the water-cooled plate unit 2 as a backup to continuously dissipate heat from the operating unit 1. See next... Figure 4 and cooperate Figure 1 If the water-cooled plate unit 2 or the heat sink unit 3 are used at the same time, as long as the judgment module 41 determines that either the water-cooled plate unit 2 or the heat sink unit 3 is not operating normally, the other one can continue to operate, thereby ensuring that at least the heat dissipation effect on the operating unit 1 can continue, thus forming a "two-way backup" in this embodiment.

[0026] The above description is merely an embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the claims and description of the present utility model shall still fall within the scope of the present utility model.
