  Hereinafter, embodiments of the present invention will be described in detail.

  In the present invention, the liquid circulation type cooling module with a cold insulation material according to the first embodiment is solidified or melted at a set temperature higher than normal temperature through a tube having good thermal conductivity connecting the circulation path through which the liquid for water cooling flows. A cold insulation material tank filled with a cold insulation material so as to cover the tube with good thermal conductivity, a liquid tank for storing liquid that has passed through the tube with good thermal conductivity of the cold insulation material tank, and a liquid in the liquid tank A pump that sucks and delivers the heat to the circulation path, a heat absorption jacket that absorbs the heat of the heating element through the heat exchange fins through the liquid that is sent from the pump and passes through the inside, and that is sent from the heat absorption jacket and passes through the inside It consists of a radiator that dissipates the heat of the liquid to the air sent by the fan motor through the air cooling fins and sends the liquid to the heat-conductive tube in the cold insulation tank. When the temperature of the liquid reaches or exceeds the set temperature by utilizing the latent heat of the state when the change of cold insulating material, characterized in that cooling the liquid.

  In addition, the liquid circulation cooling module with a cold insulation material according to the second embodiment is an uneven flow formed on the upper surface by filling the lower space where the cooling fins are formed with a cold insulation material that solidifies or melts at a set temperature higher than normal temperature. When the temperature of the liquid flowing through the passage exceeds the set temperature, the cold insulation heat exchanger that cools the liquid using latent heat when the state of the cold insulation changes, and the liquid that has passed through the cold insulation heat exchanger is sucked and circulated. A pump to be sent to the path, a heat absorption jacket for absorbing the heat of the heating element through the heat exchange fins into the liquid sent from the pump, and the heat of the liquid sent from the heat absorption jacket through the air cooling fins It comprises a radiator that radiates heat to the air sent out by a fan and sends the liquid to the upper surface of the cold insulation heat exchanger, and is characterized in that each component is arranged in a storage space and is thinned.

  A liquid circulation cooling module with a cold insulating material according to the first embodiment will be described. 1 is a perspective view of a liquid circulation cooling module with a cold insulation material according to a first embodiment of the present invention, and FIG. 2 is a block diagram of the liquid circulation cooling module with a cold insulation material according to a first embodiment of the present invention. is there.

  The liquid circulation cooling module 1 with a cold insulation material includes a cold insulation material tank 2, a liquid tank 3, a pump 4, a heat absorption jacket 5, a radiator 6, and the like, and cools the liquid 3d for cooling the heating element 9 with water.

  The cold insulation material tank 2 and the liquid tank 3, the liquid tank 3 and the pump 4, the pump 4 and the heat absorption jacket 5, the heat absorption jacket 5 and the radiator 6, and the radiator 6 and the cold insulation material tank 2 are connected by elastic tubes 8 to 8 d, and the liquid A 3d circulation path is formed.

  The liquid 3d stored in the liquid tank 3 is sucked into the pump 4, and the liquid 3d sent out from the pump 4 absorbs the heat of the heating element 9 in the endothermic jacket 5 and the temperature rises. The heat generating element 9 is cooled by heat exchange at this time.

  The liquid 3d that has passed through the endothermic jacket 5 dissipates heat to the air 7b sent out by the fan motor 7 in the radiator 6. While the temperature of the air 7b is low, the liquid 3d is cooled by exchanging heat with the air 7b by the radiator 6.

  Since the radiator 6 cannot be made lower than the temperature of the air 7b, the cooling effect is weakened when the temperature of the air 7b rises. If the temperature of the heating element 9 rises and exceeds the limit, the heating element 9 may be damaged. Operation may be restricted.

  The liquid 3 d that can no longer be air-cooled by the radiator 6 is cooled by the cold insulating material 2 e filled in the cold insulating material tank 2. The liquid 3 d cooled by the cold insulation material tank 2 or the radiator 6 is stored in the liquid tank 3.

  FIG. 3 is a graph showing the function of the cold insulating material used in the liquid circulation cooling module with the cold insulating material according to the first embodiment of the present invention.

  The cold insulating material 2e is a heat storage material that uses latent heat (absorption / release action of thermal energy) at the time of state change (melting / solidification) of a substance. For example, in the case of water, the specific heat is about 4.2 J / g, but when it melts from ice to water at 0 ° C. or higher, it absorbs about 335 J / g of heat energy from the outside.

  If the material of the cold insulating material 2e is made to be a substance that melts at a temperature higher than normal temperature, it is possible to cool to the vicinity of the melting point while the material is melting. The material for the cold insulating material 2e includes an organic material that is soft at the time of solidification and an inorganic material that is hard at the time of solidification.

  For example, organic materials include polyalkylene glycol (melting temperature 31.2 ° C., coagulation temperature 29 ° C., latent heat 86.1 J / g), and inorganic materials include sodium sulfate decahydrate (melting temperature). 32 ° C., solidification temperature 30 ° C., latent heat amount 147 J / g) and the like.

  Moreover, the set temperature of the cold insulating material 2e can be freely adjusted according to a use condition. If the melting or solidifying temperature is set to be close to the human body temperature (about 36 ° C.), the body can be cooled to 40 ° C. or lower even when the temperature of the air 7b is 40 ° C. or higher.

  The state of the cold insulator 2e (first state 9a, second state 9b, third state 9c, first state) when the environmental temperature gradually increases with time in a state where the heating element 9 continuously generates heat. Four states 9d) will be described.

  In the first state 9a, since the air temperature is lower than the temperature of the liquid 3d, the temperature of the heating element 9 can be lowered by cooling the liquid 3d with the air 7b. Since the temperature of the liquid 3d is lower than the set temperature of the cold insulating material 2e, the cold insulating material 2e is also cooled by the liquid 3d and remains in a solidified state.

  In the second state 9b, as the temperature rises, the effect of cooling the liquid 3d with the air 7b is weakened, and the effect of cooling the heating element 9 is also weakened. Along with this, the temperature of the heating element 9 also rises, and the temperature of the liquid 3d also rises.

  The melting of the cold insulating material 2e starts when the temperature of the liquid 3d becomes higher than the set temperature of the cold insulating material 2e. Further, since the air temperature is still lower than the temperature of the liquid 3d, if the temperature of the liquid 3d becomes lower than the set temperature of the cold insulating material 2e by cooling with the air 7b, the cold insulating material 2e is solidified.

  That is, melting and solidification are repeated, and the cooling function by the cold insulator 2e and the cooling function by the radiator 6 work in parallel, so that the cooling function can be maintained for a long time. The duration varies depending on the performance of the radiator 6 and the air volume of the fan motor 7.

  In the third state 9c, when the temperature further rises and becomes higher than the set temperature of the cold insulating material 2e, the temperature of the liquid 3d cannot be lowered below the set temperature of the cold insulating material 2e with the air 7b, and the melting of the cold insulating material 2e is prevented. move on.

  Since the cold insulating material 2e is used to melt the absorbed heat, the temperature is kept almost constant without increasing. Therefore, while the cold insulating material 2e is melted, the temperature of the liquid 3d is kept at the cold insulating material 2e. The temperature of the heat generating element 9 is also maintained.

  In the fourth state 9d, the cold insulating material 2e is completely melted and cannot be cooled using the latent heat of the cold insulating material 2e. The cooling effect of the liquid 3d is almost lost, and the cooling effect of the heating element 9 is almost lost.

  Accordingly, the temperature of the heating element 9 rises, the temperature of the liquid 3d rises, and the temperature of the cold insulating material 2e also rises. When the temperature of the heating element 9 reaches the heat resistant temperature, the operation is restricted and the heat generation is suppressed when the protection circuit is activated, but if the protection circuit is not provided, the temperature rises and may be damaged in some cases.

  When the cold insulation material tank 2 is opened, a tube 2d having a good thermal conductivity such as metal is curved and accommodated in the cold insulation material tank 2. The start end is connected to the inlet nozzle 2b and the end is connected to the outlet nozzle 2c. The liquid 3d passes through the tube 2d having good thermal conductivity.

  When the liquid tank 3 is opened, the inside of the liquid tank 3 becomes a storage space for the liquid 3d, and the liquid 3d that has entered from the inlet nozzle 3b is stored in the liquid tank 3 and is sucked from the pump 4 to the outlet nozzle 2c. Go out from.

  The pump 4 is a mechanism for delivering the liquid 3d to the circulation path. The pump 4 takes in the liquid 3d in the liquid tank 3 from the suction nozzle 4a, sends out the energized liquid 3d from the discharge nozzle 4b, and circulates in the path.

  When the lid 5c of the endothermic jacket 5 is opened, a heat exchanging fin 5d is provided in the endothermic jacket 5, heat exchange is performed with the liquid 3d entering from the inlet nozzle 5a, and the liquid 3d that has absorbed the heat is discharged to the outlet nozzle 5b. Get out of.

  The radiator 6 is provided with a large number of air-cooling fins 6c. The radiator 6 receives heat from the flow path of the liquid 3d from the inlet nozzle 6a to the outlet nozzle 6b and releases it into the air 7b. By blowing air by rotation, the heated air 7b is driven out. Note that heat may be radiated to the air 7b sucked by the fan 7a by reversing the blowing direction of the fan motor 7.

  FIG. 5 is a structural diagram of a cold insulation material tank in the liquid circulation cooling module with a cold insulation material according to the first embodiment of the present invention.

  The cold insulation material tank 2 is a container in which the cold insulation material 2e is put. The cold insulating material 2e is injected and filled from the lid 2a. However, in the case of the cold insulating material 2e whose melting temperature is higher than room temperature, it is injected in a heated and liquefied state.

  When the temperature of the cold insulation material 2e is reduced and solidified, the volume of the cold insulation material 2e may increase, and the internal pressure will rise abnormally. To prevent this, a little space is provided when filling. It is desirable to keep it.

  By filling the periphery of the tube 2d with good thermal conductivity disposed in the cold insulation material tank 2 with the cold insulation material 2e, the liquid 3d flowing in the tube 2d with good thermal conductivity is cooled. By accommodating the tube 2d having good thermal conductivity as long as possible by bending it, the contact area with the cold insulating material 2e is increased and the cooling effect is improved.

  The tube 2d with good thermal conductivity uses a metal or other tube with good thermal conductivity in order to conduct heat well from the liquid 3d to the cold insulation material 2e. By providing this, heat exchange can be further improved.

  In addition, since the amount of heat energy that can be absorbed from the liquid 3d is determined by the amount of the cold insulating material 2e, the size of the cold insulating material tank 2 and the amount of the cold insulating material 2e to be injected are adjusted in accordance with the time required for the cold insulating effect. .

  An elastic tube 8d that is easily bent, such as rubber, is attached to the inlet nozzle 2b, and is connected to the outlet nozzle 6b of the radiator 6. The outlet nozzle 2 c is also attached with an elastic tube 8 that is easy to bend and is connected to the inlet nozzle 3 b of the liquid tank 3.

  FIG. 6 is a structural diagram of a liquid tank in the liquid circulation cooling module with a cold insulator according to the first embodiment of the present invention.

  The liquid tank 3 is a container for storing the liquid 3d flowing through the circulation path. When the liquid 3d is initially filled, the liquid 3d is injected from the lid 3a. Note that an antifreeze such as a propylene glycol aqueous solution is used for the liquid 3d.

  When the inside of the circulation path is completely filled with the liquid 3d, the internal pressure becomes very large when the temperature rises. Therefore, the liquid tank 3 is necessary to create a space for relaxing the internal pressure. Therefore, it is desirable to provide a little space in the liquid tank 3.

  Since liquid 3d permeates through piping such as elastic tubes 8 to 8d as time elapses, a small amount of reduction occurs. Therefore, in order to use the liquid 3d for a long time, the volume of the liquid tank 3 is taken into consideration. And the amount of liquid 3d.

  Further, when gas is mixed in the circulation path, the flow of the liquid 3d tends to be stagnant and the cooling effect is lowered. Therefore, it is possible to remove the gas from the circulation path by carrying the gas to the liquid tank 3 during the circulation. is there.

  The inlet nozzle 3 b is attached with a flexible tube 8 such as rubber, which is easily bent, and is connected to the outlet nozzle 2 c of the cold insulation material tank 2. The outlet nozzle 3 c is also attached with an elastic tube 8 a that is easy to bend, and is connected to the suction nozzle 4 a of the pump 4.

  FIG. 7 is a structural diagram of an endothermic jacket in the liquid circulation cooling module with a cold insulator according to the first embodiment of the present invention.

  The endothermic jacket 5 transfers the heat of the heat generating element 9 in contact with the heat absorbing part 5e on the back surface to the heat exchanging fin 5d provided therein, and transfers the heat to the liquid 3d passing through the heat exchanging fin 5d, thereby generating the heat generating element. Reduce the temperature of 9.

  The inlet nozzle 5 a is attached with a flexible tube 8 b that is easily bent, such as rubber, and is connected to the discharge nozzle 4 b of the pump 4. In addition, an elastic tube 8c that is easily bent is attached to the outlet nozzle 5b, and is connected to the inlet nozzle 6a of the radiator 6.

  A liquid circulation cooling module 1a with a cold insulating material according to a second embodiment will be described.

  The liquid 3d existing in the cold insulator heat exchanger 10 is sucked into the pump 11, and the liquid 3d sent out from the pump 11 absorbs the heat of the heating element 9 in contact with the heat absorbing portion 12c in the heat absorbing jacket 12, and the temperature rises.

  The liquid 3d that has passed through the heat absorbing jacket 12 dissipates heat to the air 14a sent out by the fan 14 in the radiator 13. While the temperature of the air 14a is low, the liquid 3d is cooled by exchanging heat with the air 14a by the radiator 13.

  The liquid 3d that cannot be air-cooled by the radiator 13 due to the temperature rise of the air 14a is cooled by the cold insulating material 2e filled in the cold insulating material heat exchanger 10. The liquid 3 d cooled by the cold insulator heat exchanger 10 or the radiator 13 is sent to the pump 11.

  Since the fan 14 that sends air to the radiator 13 is used in combination with the cooling effect of the cold insulating material 2e, it is not necessary to increase the air volume in order to increase the cooling efficiency, and the noise can be reduced.

  FIG. 10 is an internal structure diagram of a liquid circulation cooling module with a cold insulator according to a second embodiment of the present invention.

  When the cover of the heat insulating material heat exchanger 10 is removed, the flow path 10c of the liquid 3d is formed by unevenness, and the liquid 3d flowing into the inlet 10a from the radiator 13 passes through the flow path 10c and passes from the outlet 10b to the pump 11. Sent out.

  The pump 11 is a mechanism for delivering the liquid 3d to the circulation path. The pump 11 takes in the liquid 3d from the cold insulation heat exchanger 10, sends out the energized liquid 3d, and circulates in the path. The space is saved by using a cylindrical piston type.

  When the cover of the heat absorption jacket 12 is removed, the heat exchange fin 12d is installed at the position of the heat absorption part 12c, and heat exchange is performed with the liquid 3d flowing through the path from the inlet 12a. Exit the exit 12b through the path.

  The flow path 10c is in contact with the cold insulating material 2e in the cooling tank 10d by forming a plurality of grooves so as to connect the path continuing from the inlet 10a and the path continuing to the outlet 10b. Increase the surface and improve the cooling effect.

  Into the cooling tank 10d, the cold insulating material 2e heated and liquefied from the lid 10f is injected. Further, by forming the cooling fins 10e in the cooling tank 10d, the efficiency of heat exchange with the liquid 3d passing through the flow path 10c is improved.

  Electronic components such as CPUs do not always have the same heat generation amount, and the heat generation amount also rises and falls over time, so that the protection circuit may operate and suppress functions due to a rapid rise in temperature in a short time. It is possible to cope with the temperature rise for a short time by the cooling effect of the cold insulating material.

  The thin liquid circulation cooling module with a cold insulating material can be used for a wireless transmitter of a commercial television camera. When used outdoors, the ambient temperature may be high, so that the cooling effect is improved by incorporating the present invention.
