After cooling, the fluid flows into the computer main body 110.

  The refrigerant that has passed through the heat exchange device 120 is cooled while passing through the cooler 123 and is collected in the cooling tank 130.

The cooling means 80 generates cooling air through a process of supplying, circulating, and collecting the refrigerant in the refrigerant tank 30 installed inside the case 20 detachably installed on one side of the computer main body 10 by the pumping action. The cooling air generated by the heat exchange device 40 is supplied to the inside of the computer main body 10 by the blowing force of the blower fan 50.

  First, cooling air is generated by the cooling means 80 through a process of supplying, circulating, and collecting the refrigerant in the refrigerant tank 30 installed inside the case 20 detachably installed on one side of the computer main body 10 by a pumping action. To do.

  Here, exhaust holes 21 for exhaust are formed in the front and rear wall surfaces of the case 20, and cooling air holes 22 to which cooling air is supplied are formed on opposite sides of the exhaust holes 21.

  Here, the cooling unit 80 includes a refrigerant tank 30 and a compressor 81 that raises the pressure of the low-temperature and low-pressure gaseous refrigerant to a saturation pressure corresponding to a condensing temperature that can be condensed and liquefied.

  Further, the heat generated when the high-temperature and high-pressure gaseous refrigerant received by the pumping action is changed into a cold and cooled low-temperature liquid refrigerant by the pumping action is sent to the outside by the ventilation of the condenser fan 82a. Is provided with a condenser 82 for discharging.

  The condenser 82 is installed behind the exhaust hole 21, and is configured by a refrigerant pipe 41 passing in a zigzag manner through a large number of heat radiating plates 42 arranged in parallel. The heat radiating plate 42 in which the exhaust hole 21 is formed. On the opposite side, a condenser fan 82a is installed in a space formed by cutting a part of the heat radiating plate 42 so as not to interfere with the refrigerant pipe 41.

  The condenser 82 is formed so as to be surrounded by a cover 82b attached to the case 20 so that heat generated by the condenser 82 does not flow into the case 20.

  Furthermore, an expansion valve 83 is provided so that when the liquefied refrigerant having passed through the condenser 82 is moved from a narrow passage to a wide passage, the pressure is reduced and evaporated.

On the opposite side of the heat radiating plate 42, the blower fan 50 is installed in a space formed by cutting a part of the heat radiating plate 42 so as not to interfere with the refrigerant pipe 41.

  As shown in FIGS. 10 to 13, a cooling device for cooling by cooling air flowing into a computer main body according to another embodiment of the present invention is a device for cooling heat generated in the computer main body 10, and includes a case. 20, a refrigerant tank 30 for storing and storing the refrigerant, a heat exchange device 40 in which the refrigerant supplied from the refrigerant tank 30 circulates, and cooling air generated by the heat exchange device 40 is forcibly used as a computer main body. 10 is a computer cooling device 100 including a blower fan 50 supplied to the inside of the computer 10.

  The case 20 is installed on one side of the computer main body 10, and a display 60 for displaying the operating state of the blower fan 50 and the internal temperature of the computer main body 10 is provided on one side of the case 20.

  The blower fan 50, a power switch 71 for controlling the power of the refrigerant circulation pump 31 for forcibly circulating the refrigerant, and an operation switch 72 for controlling the operation are provided.

  Here, the case 20 can be made of a metal material or a plastic material. In the present invention, the case 20 is manufactured in a rectangular parallelepiped shape so as to be easily attached to and detached from the computer main body 10.

  Cooling air is generated by the heat exchange device 40 while supplying, circulating, and collecting the refrigerant in the refrigerant tank 30 installed inside the case 10 by a pumping action.

  That is, the refrigerant in the refrigerant tank 30 is supplied, circulated and recovered by the pumping action by the refrigerant circulation pump 31.

  At this time, the heat exchanging device 40 is configured such that the refrigerant pipe 41 through which the refrigerant in the refrigerant tank 30 is circulated is positioned in a zigzag shape, and a heat radiating plate 42 that radiates heat is coupled between the refrigerant pipes 41. The

  That is, the cooling air generated in the heat exchange device 40 is supplied to the inside of the computer main body 10 by the forced air blowing force of the blower fan 50.

  Further, the case 20 can be detachably attached to the computer main body 10.

  The blower fan 50 and the refrigerant circulation pump 31 are configured to receive power from the computer main body 10 or to operate by receiving power separately.

  Further, the case 20 is configured such that the opposite side surface of the computer main body 10 is open to the outside among both side surfaces, and the heat radiating plate 42 of the heat exchange device 40 is exposed, and the blower fan 50 is exposed on the other side surface. Therefore, the cooling air can be supplied to the inside of the computer main body 10.

  A filter for removing foreign substances contained in the external air flowing in through the opening by the suction input of the blower fan 50 is further installed on the front surface of the heat exchange device 40.

  The operation and action of the present invention configured as described above will be described as follows.

  As shown in FIGS. 1 and 2, the cooling means 170 of the computer cooling apparatus 1000 according to an embodiment of the present invention is a saturation corresponding to a condensation temperature at which a compressor 171 can condense and liquefy the pressure of a low-temperature and low-pressure gaseous refrigerant. The pressure is raised to the condenser 172 in a state where the pressure is increased.

  Then, the refrigerant sent out to the condenser 172 is sent out to the expansion valve 173 instead of the low-temperature liquid refrigerant cooled from the high-temperature and high-pressure gaseous refrigerant.

  At this time, the heat generated in the condenser 172 does not flow into the computer main body 110 by the cover 172b but is discharged to the outside through the opening hole 112 by the blowing action of the condenser fan 172a.

  As described above, the liquefied refrigerant transmitted to the expansion valve 173 evaporates while being reduced in pressure when it is moved from the narrow passage to the wide passage and is transmitted to the evaporator 174.

  Further, cold air is obtained by the evaporation heat of the low-temperature and low-pressure gas refrigerant supplied to the evaporator 174 and blown into the computer main body 110 by the operation of the blower fan 140.

  That is, the evaporator 174 rapidly cools the air around the heat radiating plates 122 to form cold air.

  In addition, the low-temperature and low-pressure gaseous refrigerant transmitted to the evaporator 174 is transmitted to the compressor 171.

  At this time, the refrigerant circulating in the order of the compressor 171> the condenser 172> the expansion valve 173> the evaporator 174 flows by the pumping action of the refrigerant circulation pump 131.

  As shown in FIGS. 3 to 5 b, in order to use the computer cooling apparatus 1000 according to another embodiment of the present invention, an open hole 112 through which external air flows is formed in one side cover 111 of the computer main body 110. .

  At this time, the open hole 112 may be formed by a single number or a large number of small holes.

  The cooler 123 and the heat exchanging device 120 are installed so as to close the opening hole 112 of the side cover 111, and the blower fan 140 is fixedly installed behind the heat exchanging device 120. The side cover 111 is coupled to the case 113 in a state where it is directed toward the inside of the case 113.

  Next, power is supplied to the refrigerant circulation pump 131 and the blower fan 140 of the refrigerant tank 130. At this time, in the embodiment of the present invention, a case where power is received from the power supply unit 114 of the computer main body 110 will be described.

  As described above, when power is supplied to the refrigerant circulation pump 131, the refrigerant stored in the refrigerant tank 130 is supplied to the heat exchange device 120.

  Thus, the refrigerant by the operation of the refrigerant circulation pump 131 circulates in the refrigerant pipe 121 of the heat exchange device 120 and the blower fan 140 operates.

  At this time, the ambient air of the heat exchange device 120 is cooled by the refrigerant circulating through the refrigerant pipe 121, and passes through the heat radiation plate 122 of the heat exchange device 120 from the outside of the computer cooling device 1000 through the opening hole 111 by the operation of the blower fan 140. The air to be cooled is cooled and flows into the computer main body 110.

  The refrigerant circulating in the heat exchange device 120 for generating the cooling air is cooled while flowing in the cooling pipe 123a of the cooler 123 for re-cooling and re-enters the refrigerant tank 130, and then the heat exchange device. The circulation-recovery process sent to 120 is repeated.

  Here, heat generated in the process of cooling the refrigerant flowing in the cooler 123 is released to the outside through the cooling hole 115 and is not transmitted to the inside of the computer main body 110 by the closing plate 116, so that the cooling efficiency is lowered. To prevent that.

  In this way, the cooling air flows into the computer main body 110 and performs a cooling function together with a cooling cooler that cools the heat generated when the CPU board or graphic card of the computer main body 110 operates. .

  As a result, there is an advantage that the cooling efficiency can be increased by letting cooling air flow into the inside from the outside by removing the method of exhausting the heat generated during the operation of the existing apparatus in the computer main body 110 to the outside. .

  Further, since the computer cooling apparatus 1000 can be attached and detached as necessary, there is an advantage that it can be selectively used as necessary in use.

  A filter for removing foreign substances contained in the external air flowing in through the opening hole 112 by the suction input of the blower fan 140 is further installed on the front surface of the opening hole 112.

  As shown in FIGS. 8 and 9, the cooling means 80 of the computer cooling apparatus 100 according to still another embodiment of the present invention uses a compressor 81 to reduce the pressure of the low-temperature and low-pressure gaseous refrigerant to a condensing temperature at which condensation can be achieved. It is transmitted to the condenser 82 in a state where it is increased to a corresponding saturation pressure.

  Then, the refrigerant transmitted to the condenser 82 is transferred from the high-temperature and high-pressure gaseous refrigerant to the low-temperature liquid refrigerant and transmitted to the expansion valve 83.

  At this time, the heat generated in the condenser 82 does not flow into the case 20 by the cover 82b but is exhausted to the outside through the exhaust hole 21 by the blowing action of the condenser fan 82a.

  Thus, the liquefied refrigerant transmitted to the expansion valve 83 evaporates while being reduced in pressure when it is moved from the narrow passage to the wide passage and is transmitted to the evaporator 84.

  Further, cold air is obtained by the evaporation heat of the low-temperature and low-pressure gas refrigerant supplied to the evaporator 84 and blown into the computer main body 10 by the operation of the blower fan 50.

  That is, the air is rapidly cooled by a large number of heat radiating plates 42 installed in the evaporator 84 to form cold air.

  The low-temperature and low-pressure gaseous refrigerant transmitted to the evaporator 84 is transmitted to the compressor 81.

  At this time, the refrigerant circulating in the order of the compressor 81> the condenser 82> the expansion valve 83> the evaporator 84 flows by the pumping action of the refrigerant circulation pump 31.

  As shown in FIGS. 10 to 13, in order to use the computer cooling apparatus 100 according to another embodiment of the present invention, a supply hole 11 for supplying cooling air to one side of the computer main body 10 is formed. The

  At this time, the supply hole 11 can be formed by a single number or a plurality of small holes.

  One side surface of the case 20 of the computer cooling device 100 where the blower fan 50 is exposed is aligned with the supply hole 11 and attached to the computer main body 10.

  The case 20 and the computer main body 10 can be attached using a magnetic force or fastened with bolts. In the present invention, the case of fastening with bolts will be described as an example.

  Next, power is supplied to the refrigerant circulation pump 31 and the blower fan 50 of the refrigerant tank 30. In the present invention, a case where power is received from the power supply unit 12 of the computer main body 10 will be described as an example.

  As described above, when power is supplied to the refrigerant circulation pump 31, the refrigerant stored in the refrigerant tank 30 is supplied to the heat exchange device 40.

  Thus, the refrigerant is circulated through the refrigerant pipe 41 of the heat exchange device 40 and the blower fan 50 is activated by the operation of the refrigerant circulation pump 31.

  At this time, since the ambient air of the heat exchange device 40 is cooled by the refrigerant circulated through the refrigerant pipe 41, the blower fan 50 operates to pass through the heat radiation plate 42 of the heat exchange device 40 from the outside of the computer cooling device 100. The air is cooled and flows through the supply hole 11 of the computer main body 10.

  In this way, the cooling air flows into the computer main body 10 through the supply hole 11 and cools the heat generated when the CPU board or graphic card of the computer main body 10 operates.

  Accordingly, there is an advantage that the cooling efficiency can be improved by removing the method of discharging the heat generated during the operation of the existing apparatus in the computer main body 10 to the outside and allowing the cooling air to flow into the inside from the outside.

  Further, since the computer cooling device 100 can be attached and detached as necessary, there is an advantage that it can be selectively used as necessary in use.

  The present invention has been shown and described based on specific preferred embodiments. However, the present invention is not limited to the above-described embodiments, and the general knowledge in the technical field is within the scope of the present invention. Various changes and modifications may be possible depending on the owner.

  The present invention can be applied to various types of cooling devices for removing heat from heat-generating components in order to keep the computer within the operating temperature range.
