However, as the number of devices described above increases, the number of heat sources increases and a large amount of heat is generated from the apparatus, which may cause the system to become unstable and increase the power consumption required for operation.

  Conventionally, in order to solve the problems caused by heat dissipation, electronic equipment, power equipment, etc. arranged in a sealed space such as a machine room are provided in the equipment body when the number of equipment is small using a cooling air conditioning system. In general, cooling is performed by a heat dissipating fan. However, as the number of devices increases, the density of rack cabinets increases, and cold air does not reach all corners of the machine room, creating a place where hot air tends to concentrate, effectively reducing the temperature of the devices in the machine room There is a possibility that it cannot be done.

  In view of the above problems, some manufacturers have developed cooling devices that use liquids. The cooling device is disposed outside an electronic device, a power device, or the like, and includes a pump and a fan. A plurality of circuits are configured by connecting pipe lines between the cooling device and the heat source. The heat of the heat source is radiated by conducting heat to a cooling device arranged outside by a reflux method.

  The advantage of the cooling device described above is that heat can be moved by controlling the direction due to the high thermal conductivity and controllability of the liquid itself. However, in general, the liquid cooling device has an external structure, and a plurality of cooling circuits in the main body need to inject liquid from the outside as necessary. May enter the cooling circuit. Therefore, the cooling device not only has a complicated overall structure, but also has a drawback of being easily damaged and having a short service life. Further, each cooling circuit cannot adjust the rotation speed of the fan in accordance with the temperature change of the cooling main body and the environment, and thus there is a possibility that heat cannot be radiated stably and effectively.

  In addition, conventional cooling equipment is complex in structure and not modularized, which can be costly to install and assemble.

The first object of the present invention is that it is not necessary to supply liquid from the outside using a closed circuit, so that it is possible to prevent liquid from evaporating and impurities from entering the circuit, and the structure is simple.

The second object of the present invention is to provide a cooling system that uses a general air-conditioning outdoor unit as a condensing unit, thereby reducing the cost of the system and reducing the cost of the initial equipment of the client.
A third object of the present invention is to provide a cooling system that transmits a signal to a circuit in accordance with a load condition of a heat generation source and adjusts the amount of heat to be released and the circulation flow rate.

  In order to solve the above problems, according to a first embodiment of the present invention, a cooling system including a heat absorption circuit, a heat exchanger, a condensing unit, and a control unit, the heat absorption circuit includes a heat absorption plate, a water storage tank , Having a drain pipe and a water inlet pipe communicating with the heat absorption plate and the water storage tank, the hydraulic fluid stored in the water drain tank and the water inlet pipe being stored in the water reservoir, Connected to the heat absorption circuit, the condensing unit is connected to the heat exchanger and has at least one set of a compressor, a radiator and an expansion valve communicating with each other, and the control unit includes the compressor and the A cooling system is provided in which the expansion valve is electrically connected.

1 is a structural diagram illustrating a cooling system according to an embodiment of the present invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited thereby.

  Please refer to FIG. As shown in FIG. 1, the cooling system according to an embodiment of the present invention includes at least a heat absorption circuit 1, a heat exchanger 2, a condensing unit 3, and a control unit 4.

  The heat absorption circuit 1 includes a heat absorption plate 10, a water storage tank 11, and a drain pipe 12 and a water intake pipe 13 that communicate with the heat absorption plate 10 and the water storage tank 11, respectively. A hydraulic fluid 112 to be injected into the drain pipe 12 and the water inlet pipe 13 is stored in the water storage tank 11. The heat exchanger 2 is connected to the heat absorption circuit 1. The condensing unit 3 is connected to the heat exchanger 2 and includes at least one set of a compressor 31, a radiator 30, and an expansion valve 32 that communicate with each other. A compressor 31 and an expansion valve 32 are electrically connected to the control unit 4.

  When actually used, the heat absorbing plate 10 of the heat absorbing circuit 1 is connected to an electronic device, a power device (not shown), etc., which are objects to be radiated. The control unit 4 controls and starts up the heat absorption circuit 1, the heat exchanger 2, and the condensing unit 3, and heat generated from electronic devices, power devices and the like is absorbed by the heat absorption plate 10 and passes through the drain pipe 12. Heat is conducted to the heat exchanger 2 by the hydraulic fluid 112 and is exchanged with the condensing unit 3. The cooled working fluid 112 passes through the water storage tank 11 and is sent from the water inlet pipe 13 into the heat absorbing plate 10 to circulate. The condensing unit 3 performs a heat cycle by the compressor 31, the radiator 30 and the expansion valve 32 to radiate heat.

  In this way, since a closed circuit that does not require the supply of liquid from the outside is used, it is possible to prevent liquid from evaporating and impurities from entering the circuit, and the structure is simple and the cooling system is stable. The heat can be effectively dissipated.

  In the present embodiment, two sets of the compressor 31, the radiator 30 and the expansion valve 32 of the condensing unit 3 are provided in order to enhance the heat dissipation effect.

  In the condensing unit 3 described above, a general air-conditioning outdoor unit is installed so that the cost for the system can be reduced and the initial cost for the client (for example, construction in a building, a house, etc.) can be reduced. May be used.

  The above-described electronic device, power device, and the like may be an information device (for example, a server), a communication device (for example, a television, a radio, a wireless transmitter), a transformer rectifier (for example, an inverse conversion device, a rectifier), or the like. .

  The water storage tank 11 may be connected to an exhaust valve 111 used for venting gas generated in the drain pipe 12 and / or the water inlet pipe 13 of the heat absorption circuit 1.

  An expansion tank 14, a filling pump 15, a first pressure sensor 16, a second pressure sensor 17, a temperature sensor 18, and a main pump 19 may be disposed in the above-described inlet pipe 13. The first pressure sensor 16, the second pressure sensor 17, the temperature sensor 18, and the main pump 19 are electrically connected to the control unit 4, respectively. Therefore, the control unit 4 can control the operating state of the entire cooling system by detecting and feeding back the parameters.

  The control unit 4 includes an operation interface 21, an environmental temperature / humidity sensor 22, a communication interface 23, a speed control device 24, and at least one fan 25 (this book) connected to the speed control device 24 and corresponding to the radiator 30. In the embodiment, as illustrated in FIG. 1, the number of fans 25 may be two so as to correspond to the radiator 30. The control unit 4 can control the operating status of the entire cooling system by detecting and feeding back the parameters.

  Specifically, when the entire cooling system is activated, the user 20 presets the related condition values of the environmental temperature / humidity sensor 22 and the speed control device 24 through the operation interface 21 or sets the related condition values through the communication interface 23. The heat absorption circuit 1 and the condensing unit 3 perform the heat exchange based on the set condition value, and also the load condition of the information device and the temperature / humidity detected by the environmental temperature / humidity sensor 22. Based on the change and the change in temperature detected by the temperature sensor 18, a signal is transmitted from the speed control device 24 to the fan 25 to control the rotation speed (that is, the fan 25 blows gas to the radiator 30). . Thereby, the amount of heat released can be adjusted, and the main pump 19 of the heat absorption circuit 1 can adjust the circulation flow rate of the working fluid 112 passing through the drain pipe 12 or the water inlet pipe 13 based on various signals. The main pump 19 may use an inverter type pump or a double pump structure as required.

  When the hydraulic fluid 112 passing through the inlet pipe 13 of the heat absorption circuit 1 circulates, the pressure in the heat absorption circuit 1 is detected by the first pressure sensor 16 and the second pressure sensor 17. When it is detected that an abnormality has occurred, a warning is issued by the operation interface 21 and the pressure is released by the expansion tank 14. When a special situation occurs and the hydraulic fluid 112 decreases, the hydraulic fluid 112 may be replenished by the filling pump 15.

  That is, the entire cooling system transmits a signal to the circuit in accordance with the load condition of the heat source, and adjusts the amount of heat released and the circulation flow rate.

  The hydraulic fluid 112 described above may be cooling water or other cooling medium. The heat absorption circuit 1 and the condensing unit 3 are closed circuits, and the working fluid 112 in the closed circuit may be cooling water or a coolant to which additives such as antibiotics and rust inhibitors are added.

  Since the heat absorption circuit 1 and the condensing unit 3 are closed circuits, it is not necessary to supply hydraulic fluid from the outside. Therefore, it is possible to prevent the working fluid from evaporating and impurities from entering the circuit.

  The communication interface 23 described above may be a Web protocol, SNMP protocol, MODBUS (registered trademark) protocol, LONWORKS (registered trademark) protocol, or N20 pen protocol.

  Quick joints 121 and 131 may be attached to the drain pipe 12 and the water inlet pipe 13 so that they can be easily attached and detached.

  Since the cooling system of the present invention uses a closed circuit, it is not necessary to supply liquid from the outside, the liquid can be prevented from evaporating and impurities, and the structure is simple and the system is stable. The heat can be effectively dissipated. Further, by using a general air-conditioning outdoor unit as a condensing unit, the cost for the system can be reduced and the cost for the initial equipment of the client can be reduced. Furthermore, according to the load condition of the heat source, a signal can be transmitted to the circuit to adjust the amount of heat to be released and the circulation flow rate.

  The preferred embodiments of the present invention have been disclosed as described above so that those skilled in the art can understand them, but these do not limit the present invention in any way. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the utility model registration claim of the present invention should be broadly interpreted including such changes and modifications.
