[0034] Existing computer rooms are usually equipped with multiple energy-intensive devices to achieve high-performance computing or data transmission and exchange functions. In order to keep high-energy-consuming devices operating at a suitable temperature, computer rooms are usually equipped with air-conditioning systems for heating and cooling.

[0035] In some harsh environments, such as those with large temperature differences between day and night, the fluctuating temperatures can easily affect the performance of the equipment in the computer room. In some environments with distinct four seasons, the temperature changes with the seasons can also affect the performance of the equipment in the computer room. In order to keep high-energy-consuming equipment operating at a suitable temperature, the computer room is usually equipped with two air-conditioning systems, one for heating and one for cooling. This greatly occupies the remaining space in the computer room and increases the cost of setting up the computer room.

[0036] In order to solve the above problems, the present invention proposes a liquid cooling air conditioning temperature control system, which aims to provide a liquid cooling air conditioning temperature control system that can achieve heating and cooling at the same time, occupies a small area and is low in cost. Figures 1 to 2This is a structural diagram of an embodiment of the liquid cooling air conditioning temperature control system provided by the present utility model.

[0037] Please refer to Figures 1 to 2 In one embodiment of the present invention, the liquid-cooled air-conditioning temperature control system 100 includes a water delivery device 1, a regulating device 2 and a reversing device 3; the water delivery device 1 is used to deliver hot water and cold water; the regulating device 2 includes a fluid pipeline 21, each having a water inlet port 211 and a water outlet port 212 at both ends; the reversing device 3 is arranged between the water delivery device 1 and the regulating device 2, and is connected to the water delivery device 1 through the reversing device 3 to deliver hot water or cold water to the fluid pipeline 21; wherein, the liquid-cooled air-conditioning temperature control system 100 has a heating mode and a cooling mode. When in the heating mode, the fluid pipeline 21 circulates hot water from the water inlet port 211 to the water outlet port 212; when in the cooling mode, the fluid pipeline 21 circulates cold water from the water inlet port 211 to the water outlet port 212.

[0038] The technical solution of the present invention adopts the reversing device 3 to connect the water delivery device 1 to deliver hot water or cold water to the fluid pipeline 21. When in the heating mode, the fluid pipeline 21 circulates hot water from the water inlet port 211 to the water outlet port 212; when in the cooling mode, the fluid pipeline 21 circulates cold water from the water inlet port 211 to the water outlet port 212. With this arrangement, both the heating and cooling functions can be realized for the computer room, thereby keeping the computer room at an appropriate temperature at all times. At the same time, the heating and cooling functions are from the same system, thereby greatly saving the space of the computer room in terms of structure, saving the cost of setting up the computer room, and improving the economy.

[0039] For further information, please refer to Figures 1 to 2 The water delivery device 1 includes a cooling water tower 11, a water inlet pipe 12 and a water outlet pipe 13; the water inlet pipe 12 is used to provide hot water to the cooling water tower 11, and the water inlet pipe 12 is provided with a first diversion pipe 121 for connecting to the water inlet port 211 in the heating mode; the water outlet pipe 13 is used to discharge the cold water cooled by the cooling water tower 11; the water outlet pipe 13 is provided with a second diversion pipe 131 for connecting to the water inlet port 211 in the cooling mode.

[0040] Understandably, please refer to Figures 1 to 2In order to achieve the technical purpose that, in the same system, when in heating mode, the fluid pipeline 21 circulates hot water from the water inlet port 211 to the water outlet port 212; when in cooling mode, the fluid pipeline 21 circulates cold water from the water inlet port 211 to the water outlet port 212, the water delivery device 1 includes the cooling water tower 11, the water inlet pipe 12 and the water outlet pipe 13; specifically, the water inlet pipe 12 is used to provide hot water to the cooling water tower 11, and the water outlet pipe 13 is used to discharge the cold water cooled by the cooling water tower 11. In this way, the water delivery device 1 is configured to pass through the water inlet pipe 12, the cooling water tower 11 and the water outlet pipe 13. The water outlet pipe 13 forms a heat circulation path. Then, the water inlet pipe 12 and the water outlet pipe 13 are respectively provided with the first diversion pipe 121 and the second diversion pipe 131. Through the reversing device 3, when in the heating mode, the first diversion pipe 121 is connected to the water inlet port 211 of the fluid pipeline 21, so that the fluid pipeline 21 is filled with hot water, thereby generating a heating function; or through the reversing device 3, when in the cooling mode, the second diversion pipe 131 is connected to the water inlet port 211 of the fluid pipeline 21, so that the fluid pipeline 21 is filled with cold water, thereby generating a cooling function.

[0041] For further information, please refer to Figures 1 to 2 The liquid-cooled air conditioning temperature control system 100 also includes a connecting device, which includes a first tee and a second tee; the first diversion pipe 121 is connected to the water inlet pipe 12 through the first tee; the second diversion pipe 131 is connected to the water outlet pipe 13 through the second tee. It is understandable that in this embodiment, in order to more conveniently control the direction of liquid flow in the circulation loop, the first shunt pipe 121 is connected to the water inlet pipe 12 through the first tee, and the second shunt pipe 131 is connected to the water outlet pipe 13 through the second tee. In this way, without affecting the self-circulation of the water inlet pipe 12 providing hot water to the cooling water tower 11 and the cooling water tower 11 discharging the cooled cold water from the water outlet pipe 13, it is also possible to further connect the water inlet port 211 of the fluid pipeline 21 to the first shunt pipe 121 or the second shunt pipe 131 according to actual needs through the reversing device 3, so that hot water or cold water circulates in the fluid pipeline 21, thereby achieving the function of heating or cooling, that is, keeping the machine room at a suitable temperature. It should be noted that the first tee and the second tee are not marked in the drawings of the specification.

[0042] In addition, please refer to Figures 1 to 2The reversing device 3 includes a water pump 31, which is connected in series to the fluid pipeline 21 near the water inlet port 211. It can be understood that in this embodiment, in order to increase the speed of extracting liquid from the water inlet port 211 of the fluid pipeline 21 and thereby accelerate the efficiency of the circulation, the reversing device 3 includes the water pump 31, which is connected in series to the fluid pipeline 21 near the water inlet port 211. The operation of the water pump 31 generates a negative pressure in the fluid pipeline 21, thereby quickly pressing hot water or cold water into the fluid pipeline 21, thereby causing the fluid pipeline 21 to cool down or increase the temperature of the equipment in the machine room, so that the equipment in the machine room operates at a suitable temperature.

[0043] For further information, please refer to Figures 1 to 2 The reversing device 3 further includes a four-way valve 32, wherein one side of the four-way valve 32 is connected in parallel to the first shunt pipe 121 and the second shunt pipe 131, and the other side is connected in parallel to the water inlet port 211 and the water outlet port 212 of the fluid pipeline 21. In order to realize the reversing function of the reversing device 3, that is, when in the heating mode, the first shunt pipe 121 of the water inlet pipe 12 is connected to the water inlet port 211 of the fluid pipeline 21, and the water outlet port 212 is connected to the second shunt pipe 131, thereby realizing the thermal cycle of the regulating device 2 and playing a heating role for the equipment in the machine room; when in the cooling mode, the second shunt pipe 131 of the water outlet pipe 13 is connected to the water inlet port 211 of the fluid pipeline 21, and the water outlet port 212 is connected to the first shunt pipe 121. The four-way valve 32 is connected to the first shunt pipe 121 and the second shunt pipe 131 in parallel on one side, and the water inlet port 211 and the water outlet port 212 of the fluid pipeline 21 on the other side are connected in parallel. In this way, through the setting of the four-way valve 32, both the heating effect and the cooling effect can be achieved in the liquid-cooled air-conditioning temperature control system 100.

[0044] In addition, please refer to Figures 1 to 2The liquid cooling air conditioning temperature control system 100 further includes a control system, which is electrically connected to the water pump 31 to control the flow rate of the water pump 31. It is understandable that under different temperature environments, the efficiency of the heat cycle or the cold cycle is different. For example, taking 20 degrees Celsius as an example, at 20 degrees Celsius, neither cooling nor heating is required. When the temperature is below 20 degrees Celsius, heating is required. It can be seen that the lower the temperature, the more it is necessary to improve the efficiency of the heat cycle so that the temperature can be increased as quickly as possible and maintained at 20 degrees Celsius. It is understandable that the heating efficiency at 0 degrees Celsius must be higher than the heating efficiency at 10 degrees Celsius. In order to achieve the above technical effects, the liquid-cooled air-conditioning temperature control system 100 also includes the above-mentioned control system, which is electrically connected to the water pump 31 to control the flow rate of the water pump 31. In this way, the cooling efficiency or heating efficiency of the liquid-cooled air-conditioning temperature control system 100 can be precisely controlled. Specifically, the larger the flow rate of the water pump 31, that is, the faster the flow rate, the higher the heating or cooling efficiency.

[0045] For further information, please refer to Figures 1 to 2 The control system is electrically connected to the four-way valve 32 to control the opening of the four-way valve 32 and the direction of liquid flow. It is understood that in order to further improve the control accuracy of the flow rate and flow direction of the water delivery device 1 input into the fluid pipeline 21, the control system is electrically connected to the four-way valve 32 to control the valve opening and liquid flow direction of the four-way valve 32, thereby further controlling the flow rate and direction of cold water or hot water flowing into the fluid pipeline 21.

[0046] For further information, please refer to Figures 1 to 2 The control system is also electrically connected to the cooling water tower 11 to control the flow rate of the cooling water tower 11. It is understood that in order to further improve the control accuracy of the flow rate of hot water or cold water input into the fluid pipeline 21, by setting a control system electrically connected to the cooling water tower 11, by controlling the flow rate and pressure provided by the cooling water tower 11, the flow rate of hot water or cold water flowing into the first diversion pipe 121 and the second diversion pipe 131 is controlled, thereby controlling the cooling or heating efficiency of the entire liquid-cooled air conditioning temperature control system 100.

[0047] In addition, please refer to Figures 1 to 2The liquid-cooled air conditioning temperature control system 100 further includes a battery device housing 4, which is provided with the radiator, or the radiator is attached to the battery device housing 4. It is understood that in this embodiment, the radiator can be used for heat dissipation or heating. By attaching the radiator to the device or providing the radiator as part of the battery device housing 4, the heating or cooling efficiency of the radiator for the battery device can be improved.

[0048] In another embodiment, the liquid-cooled air-conditioning temperature control system 100 further includes a cabinet having multiple power modules and multiple IT modules therein. The radiator can be configured as a heat sink in multiple numbers, and the multiple heat sinks are spaced apart between the multiple power modules or the multiple IT modules so that the heat sinks provide heat dissipation or heating for the power modules or the IT modules through single-sided or double-sided lamination, thereby improving the heat dissipation or heating efficiency of the heat sinks.

[0049] Furthermore, the radiator includes cooling fins and a cooling fan, which are spaced apart and arranged on the battery device housing 4. It will be appreciated that in this embodiment, the radiator utilizes cooling fins (unlabeled) in conjunction with a cooling fan (unlabeled) to promote rapid circulation of air near the radiator, thereby regulating the temperature of the device's surroundings and improving the radiator's heat dissipation efficiency for the device.

[0050] It can be understood that the fluid pipeline 21 of the regulating device 2 is prone to heat loss when its temperature is too high, which is not conducive to the overall cooling of the regulating device 2 and is prone to damage. Therefore, in order to avoid damage to the fluid pipeline 21 and ensure the stability of the regulating device 2, the fluid pipeline 21 is also provided with the radiator with the cooling fins, which is used to take away the heat in the space of the regulating device 2 or dissipate the heat outward, thereby ensuring the stability and reliability of the adjusting device 2.

[0051] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
