Description

  In the present invention, the heat of the high heat source can be freely transferred to the low heat source through an arbitrary path, the standardization is easy, the heat of any heat source can be transferred, and each heat source is arranged at an arbitrary position. The present invention relates to a heat transfer cable, a transfer cable unit, a heat transfer system, and a heat transfer system construction method.

In recent years, with the progress of semiconductor technology, the processing power of computers such as personal computers (hereinafter referred to as personal computers) has been dramatically improved, and the momentum is expected to increase further in the future. This is because the processing speed of the computer is remarkably increased and is expected to increase in the future as well, so that the calorific value (heat generated per unit area) of electronic components such as circuit boards will be 100 W / cm ^{2 to} 300 W / in the near future. increased to approximately cm ^2, the amount of heat generated which from equipped with electronic devices is expected to continue also increased dramatically in the future.

  Conventionally, heat dissipation treatment of such electronic devices, electrical devices, and other thermal devices has been considered exclusively as an internal problem in each device (unique matter to be solved in each device). Therefore, even when a plurality of heat generating devices are installed in a common environment, the heat generating devices are arranged as they are without considering each other's existence. Naturally, it lacked the macro viewpoint of unifying the entire environment and improving heat dissipation. As an example, there may be a case where a cooling device is installed in the vicinity of the heat sink of the refrigerator in one room.

  Nevertheless, this was rarely a problem while the calorific value was small. However, if the calorific value increases in the future, this becomes a problem that cannot be ignored. That is, the premise of the conventional idea is that the calorific value is small, and there is a possibility that the premise itself will collapse in the future. Energy resources are limited, and there are also problems such as wasteful consumption of energy and global warming. Heat dissipation treatment is not only an internal problem of each heat generating device, but also a macro problem of the specified environment, region, etc. Need to be considered.

  At present, the flow of technology is changing from a concentration-oriented direction to a decentralized direction due to advances in computer technology and network technology. However, in order to achieve the above-described macro-like improvement, it is considered that centralized processing is more effective than decentralization, even if it goes against this flow. Therefore, in the future, it is necessary to consider not only the heat dissipation of each heat generating device but also the improvement of heat dissipation by centralized processing for a plurality of devices. And the heat transfer system which supports this and the construction method which can construct | assemble this heat transfer system easily are desired.

  Therefore, conventional means for heat transfer and heat transfer methods will be described. Conventionally, there is a heat pipe as means for transferring the heat at point A to point B. A heat radiator using this heat pipe has already been proposed (see, for example, Patent Document 1). A fluorocarbon medium is sealed in a sealed container made of aluminum and formed in a hollow panel shape, and heat of a heating element such as a power transistor placed at one end is transferred to a radiation fin on the other end side.

  However, the radiator of Patent Document 1 is a metal hardware with low flexibility, and does not exceed the range of heat transfer in the housing, specifically, the range of heat transfer from the heat generating part to the heat radiating part. That is, it is unrelated to the above-described heat transfer between a plurality of devices, and is not related to a heat transfer means and a heat transfer system independent of each device.

  In order to solve the problem of inflexibility and capacity of the heat pipe, a heat transport device that transports heat generated by the heat generating member to a heat radiating member placed in an arbitrary place, and cooling an electronic device equipped with the heat transport device An apparatus has been proposed (see Patent Document 2 and Patent Document 3). In the heat transport device proposed in Patent Document 2, two flat headers are connected by a plurality of flexible tubes, and a liquid is sealed inside. Fins are provided inside each header, and heat is transferred from the header wall to the liquid inside. One header is provided with a bellows and expands and contracts by a drive mechanism, and the liquid reciprocates between the headers via the flexible tube due to the volume change. In addition, it has been proposed to circulate liquid by a small pump instead of reciprocation.

  Moreover, the electronic device cooling device of Patent Document 3 uses the heat transport device of Patent Document 2 to flexibly connect the heat generating member and the metal housing wall, receive heat at the heat receiving portion, and dissipate heat at the heat radiating portion. . Accordingly, the heat generating member and the housing wall can be easily connected without being influenced by the component arrangement, and heat is transported with high efficiency by the vibration of the liquid. In the heat dissipating part, the heat dissipating member and the metal casing wall are thermally connected, and because of the high thermal conductivity of the metal casing, the heat is widely diffused to the casing wall and high heat dissipation performance is obtained. .

  An anti-phase forced vibration type heat pipe has also been proposed as a heat pipe for reciprocally vibrating the liquid described above (see Patent Document 4). It is a heat pipe that transfers heat only by vibration without using the phase change of fluid. However, this heat pipe only discloses high-performance heat transfer means, and how it can be combined with other equipment and devices to improve overall thermal efficiency, It is not a technology in terms of whether a heat transfer system can be constructed.

  Furthermore, an apparatus has been proposed in which a notebook personal computer is connected to a power source via an A / D converter, and the A / D converter, the conductor, and the cooling path are integrated by a composite cable (see Patent Document 5). In this composite cable, a conductor and an A / D converter are surrounded by an outer sheath, and a space between the outer sheath and the conductor is used as an air flow path for compressed air, or a conductor and an A / D are coated with an outer sheath. The liquid passage for cooling is accommodated together with the conversion device. For this reason, an adapter is constituted by these, and a compressor or a pump is accommodated together with the A / D converter, and a power cord and an outlet plug are connected to the adapter.

JP-A-2-244748 JP-A-6-120384 JP-A-7-142886 JP 2002-364991 A JP 2000-10661 A

  As explained above, the heat dissipation treatment of each device is conventionally regarded as an internal problem, and even if multiple devices are installed in a certain environment, the heat dissipation is improved throughout the environment. It was lacking in a proper viewpoint. And the conventional way of thinking based on the premise that the calorific value is small is required to change the way of thinking. However, even if macroscopic heat dissipation is improved, the heat dissipation inherent to each device must not be neglected. Both need to be compatible.

  The techniques proposed in Patent Documents 1 to 4 are all techniques for improving the performance of heat transfer means themselves, or improving the heat dissipation of electronic devices, etc. It does not improve the performance.

  In this respect, Patent Document 5 uses a composite cable in which a conducting wire and a cooling path are integrated to cool a heating element of a notebook personal computer using an adapter incorporating a compressor or a pump and an A / D converter. However, this is related to the internal cooling of the notebook computer and the cooling of the power supply system. It transports heat to an external cooling device with high efficiency, is versatile and independent of the equipment. Is not disclosed.

  In the future, it will be necessary to increase the efficiency of heat utilization in the region and other environments from such a macro perspective. For this purpose, a general-purpose heat transfer system capable of transporting heat whatever the object is desired. At this time, if the heat transfer cable is standardized as a basic technology, a heat transfer system can be constructed very easily, easily and quickly so that anyone can assemble the same control system and communication network using electrical and communication cables. .

It is explanatory drawing of an example when an assembly heat transfer socket is fixed indoors.

  In FIG. 1, 1 is a heat generating device represented by an electronic device such as a personal computer (high heat source of the present invention), 2a is a large amount of exhaust heat collected from various heat generating devices 1 including one or two large-sized devices. The large cooling unit indoor unit 2b for radiating heat in a concentrated manner is a small cooling unit that radiates a relatively small amount of exhaust heat moved from one or two or more heating devices 1. Hereinafter, the cooling devices such as the large cooling unit indoor unit 2a and the small cooling unit 2b are collectively referred to as the cooling device 2 (low heat source of the present invention).

  The heat generating device 1 shown in FIG. 1 is a notebook personal computer. It may be a desktop personal computer, an electronic device equipped with other heat generating electronic components, an electrical device, or a thermal device. Naturally, the cooling device 2 is not limited to the large cooling unit indoor unit 2a and the small cooling unit 2b. The cooling device 2 is not limited to radiating the heat collected by heat exchange from the heat generating device 1, but also the heat exchanged heat. What is provided as a second heat source is also included.

  Next, 3 shown in FIG. 1 is a heat transfer cable that is flexible and can freely change the shape of the flow path. This heat transfer cable 3 is provided with heat exchange plugs 5 and 7 described below in a pair and arranged in a loop. The heat transfer cable 3 is filled with a refrigerant to form a cooling circuit, and a pump is used for the refrigerant. Is circulated, heat is taken away by the heat generating device 1 and radiated by the cooling device 2. Reference numeral 4 denotes a flexible fluid cable body that constitutes the heat transfer cable 3 and in which a refrigerant flows.

  Further, 5 is a heat exchange plug on the side of the heat generating device 1 constituting the heat transfer cable 3, 6 is a heat connecting portion protruding in a pin shape from the heat exchange plug 5 and configured as a heat pipe, and 9a is a heat generating device. These are a plurality of insertion holes into which a thermal connection portion 6 (heat pipe) provided in one housing 9 (described later in FIG. 3A) can be inserted. On the back surface of the insertion hole 9a, a plurality of heat transfer sockets 6a (to be described later with reference to FIG. 3B) on the side of the heat generating device 1 that is detachably fitted to the heat connecting portion 6 are provided. The pin-shaped heat connection portion 6 is inserted into the insertion hole 9a, and the heat exchange plug 5 and the heat transfer socket 6a are physically and thermally connected.

  Similarly, 7 is a heat exchange plug on the side of the cooling device 2 such as the large cooling unit indoor unit 2a and the small cooling unit 2b, and 8 is a cooling device side projecting a plurality of pins from the heat exchange plug 7 in the form of pins. 9b is a plurality of insertion holes which are provided in the casing 9 of the cooling device (which will be described later with reference to FIG. 3A) and into which the thermal connection portion 8 (heat pipe) can be inserted. . On the back surface of the insertion hole 9b, a plurality of heat transfer sockets 8a (to be described later with reference to FIG. 3C) on the cooling device side that are detachably fitted to the heat connection portion 8 are provided. The heat exchange plug 7 and the heat transfer socket 8a are physically and thermally connected. As described above, the heat connecting portions 7 and 8 are constituted by several heat pipes, and heat exchange is performed through a plurality of paths, so that the load per one is small and a large amount of heat can be transmitted. It should be noted that, as described above, instead of projecting a plurality of pipes, if necessary, only one heat pipe may be formed and projected.

  Here, the heat transfer cable unit will be described. The heat transfer cable unit includes the pair of heat transfer cables 3 described above (the flexible fluid cable main body 4 and its heat exchange plugs 5 and 7 and its heat connection parts 6 and 6. 8), a heat transfer socket 6a on the side of the heat generating device 1 and a heat transfer socket 8a on the side of the cooling device 2 that are fitted to the heat connecting portions 6 and 8. The heat transfer cable 3, and therefore the heat transfer cable unit including the heat transfer cable 3, can standardize the cable standard by at least the amount of heat transferred and the temperature difference, the temperature of the high heat source, etc., regardless of the type of the heating device 1 or the cooling device 2 If the heat connecting portions 6 and 8 and the heat transfer sockets 6a and 8a can be physically and thermally connected, heat can be transferred from the high heat source to the low heat source. If the cable standard is standardized (standardized) in this way, a general-purpose heat transfer system can be constructed simply, easily and freely so as to assemble a network simply by selecting a heat transfer cable unit.

  In the heat transfer system of the first embodiment, one or two or more heat generating devices 1 are thermally connected to a common cooling device 2 through heat transfer cable units, respectively, and the heat generated in each heat generating device 1 is generated. It is taken away by heat exchange and transferred to the cooling device 2, where it radiates heat intensively. Therefore, unlike the conventional heat generating device 1, the heat dissipating function built in the main body of the heat generating device 1 is separated from the main body function and discharged to an external cooling device 2 installed at an arbitrary place independent of each heat generating device 1. It is possible to transfer heat and dissipate heat.

  By the way, in an electronic device such as a notebook personal computer that is carried and used, it is desirable that the exhaust heat function via the heat transfer cable 3 and the built-in heat dissipation function can be selectively used. . That is, if the heat exchange plug 5 of the heat transfer cable 3 is removed, the heat dissipation function built in the portable electronic device functions, and when the heat exchange plug 5 is inserted into the heat transfer socket 6a, the heat transfer cable 3 is connected via the heat transfer cable 3. It is preferable that intensive cooling by the external cooling device 2 becomes possible. In other words, it is a concentrated heat dissipation function or a built-in heat dissipation function as an optional function in a portable electronic device.

  For this reason, the heat-generating electronic component of such a device has an original heat dissipation function, for example, a heat sink or the like and the heat transfer socket 6a can be selectively thermally connected, and the heat is exhausted through the heat transfer cable 3. Then, if possible, it is better to stop the internal cooling operation of the cooling fan or the like. As will be described later, the heat transfer cable unit of the first embodiment is a cooling circuit using a two-phase refrigerant heat cycle, and the heat connection portions 6 and 8 are a plurality of heat pipes, and the heat of the two-phase heat medium. Since the transmission is used, it is possible to remove a heat flux much larger than the heat generation density of the heat generating electronic component, and it has a large cooling capacity.

  Then, the heat transfer cable 3 which comprises a heat transfer cable unit is demonstrated based on Fig.2 (a). In FIG. 2A, 11 constitutes a flow path of a refrigerant having a low boiling point and a large latent heat flowing inside, for example, water, fluorinate (fluorine inert liquid) such as Fluorinert FC-72, and an alcohol aqueous solution such as butanol. It is a flexible refrigerant pipe. Reference numeral 12 denotes a heat insulation coating layer of the heat transfer cable 3 that covers the periphery of the flexible refrigerant tube 11.

  In Example 1, in order to comprise a heat transfer cable unit, the flexible fluid cable main body 4 is used as a pair. FIG. 2B shows a cross section of the flexible refrigerant pipe 11 portion of the heat transfer cable unit. Reference numeral 3a in FIG. 2 (b) denotes this heat transfer pair cable. In one cable of the heat transfer pair cable 3a, the gas-liquid two-phase refrigerant partially vaporized by the heat generating device 1 (the gas-liquid mixed refrigerant in the first embodiment of the present invention) or the completely vaporized gas refrigerant, and the other The liquid refrigerant cooled by the cooling device 2 flows through the cable. Therefore, the cross-sectional area of the flexible refrigerant pipe 11 through which the gas-liquid two-phase refrigerant or gas refrigerant flows is formed larger than the cross-sectional area through which the liquid refrigerant flows. And when this heat transfer pair cable 3a is employ | adopted, the cross-sectional area of a pair of flexible fluid cable main body 4 can be minimized.

  When this heat transfer pair cable 3a is used, in addition to flexibility, the heat transfer cable 3 as a whole can be highly insulated, reduced in cross section, and reduced in cost. Moreover, since the pair has an integrated structure, the heat transfer cable 3 can be easily handled. Of course, it is possible to use two heat transfer pair cables 3 without using the heat transfer pair cables 3a.

  Since the cooling circuit (heat exchange circuit) using the two phases of the refrigerant is used in the first embodiment (see FIG. 7A), the heat is received by the heat generating device 1 and vaporized (evaporated). Condensate. For example, in the case of water, the refrigerant has a boiling point of 100 ° C. and a latent heat of 539 cal / g, and Fluorinert FC-72 has a boiling point of 56 ° C. and a latent heat of 21 cal / g. When water is used, scorching increases, but when used under atmospheric pressure, a two-phase flow cannot be used up to a boiling point of 100 ° C. The heat resistance temperature of the semiconductor electronic component is about 80 ° C., and the ambient air temperature may be close to 40 ° C. On the other hand, if Fluorinert FC-72 is used, it boils at a temperature of 56 ° C., and a liquid circulation type cooling circuit for semiconductor electronic components and the like by a two-phase flow can be easily realized. When using in such a way that the temperature drops in winter, it is preferable to use an antifreeze solution.

  Even when two phases of refrigerant are used, a refrigeration cycle type cooling circuit (described later) shown in FIG. 8A can also be used. In this case, since the heat radiation temperature can be increased by adding the refrigerant compression process, a larger heat radiation amount can be secured, thereby moving a larger amount of heat from the heat generating device 1 or the temperature level of the heat generating device 1. Can be made lower. That is, the range of the operating pressure and operating temperature level of the heat transfer system can be expanded as compared with the pump loop type cooling circuit of FIG. 7A, and the applicability is further enhanced.

  In addition, since heat efficiency will fall if external heat | fever is transmitted to the refrigerant | coolant which flows through the inside of the flexible refrigerant | coolant pipe | tube 11, the flexible refrigerant | coolant pipe | tube 11 is coat | covered with a highly heat-insulating coating layer 12 and a flexible urethane foam. The distance between the two flexible refrigerant pipes 11 arranged in the heat transfer pair cable 3a depends on the materials of the flexible refrigerant pipe 11 and the heat insulating coating layer 12, but the refrigeration cycle type cooling circuit of FIG. Then, since the temperature level of both is different, it is better to keep the distance between them as far as possible. However, since the heat transfer pair cable 3a becomes a wide cable and becomes difficult to handle if it is separated too much, it is preferable to use the heat transfer pair cable 3a separated within a range of 1 cm to 3 cm when urethane foam or the like is used. On the other hand, in the pump loop type cooling circuit of FIG. 7A, there is almost no difference in the temperature level between the two flexible refrigerant pipes 11, so that it may be about 1 cm when urethane foam or the like is used.

  In Example 1, in order to give a flexible property to the flexible refrigerant tube 11, the flow path is made of stainless steel 4 mm to 10 mm bellows. However, it can also be made of aluminum, other metals, or resin. However, there is a problem of compatibility between the refrigerant and the flexible refrigerant pipe 11 material, and it is necessary that the material does not change due to contact with the refrigerant such as corrosion. In addition, since it is difficult to avoid non-condensable gases such as air from being mixed in the refrigerant, it is necessary to use materials and structures that are as few as possible. In order to improve compatibility with such a refrigerant, it is also preferable to coat the inner wall of the flexible refrigerant pipe 11 with a corrosion-resistant and permeation-resistant material to prevent them. In addition, when resin is employ | adopted as a material of the flexible refrigerant | coolant pipe | tube 11, a flexible pipe can be easily formed by utilizing the softness | flexibility of resin itself. However, in this case, it is necessary to take measures for the compatibility, and it is inevitable to periodically remove mixed air and the like.

  Next, the thermal connection parts 6 and 8 will be described. The thermal connection portions 6 and 8 of the first embodiment are heat pipes, which are used by being inserted into the casings of the respective devices. In FIG. 3A, reference numeral 9 denotes a casing of the cooling device 2 such as a heating device 1 such as a personal computer, a large cooling unit indoor unit 2a, and a small cooling unit 2b. As described above, the heat generating device 1 and the housing 9 of the cooling device 2 are provided with insertion holes 9a and 9b for inserting the thermal connection portions 6 and 8, respectively. The housing 9 of the heat generating device 1 is provided with a heat transfer socket 6a on the back surface of the insertion hole 12a, and the housing 9 of the cooling device 2 is provided with a heat transfer socket 8a on the back surface of the insertion hole 9b. One ends of the thermal connection portions 6 and 8 inserted from the insertion holes 9a and 9b are fitted into the heat transfer sockets 6a and 8a, and are thermally connected. The heat transfer sockets 6a and 8a are further thermally connected to heat generating electronic components in the heat generating device 1 and to a heat exchange member for cooling (for example, a heat radiating fan) in the cooling device 2. . The other ends of the heat connecting portions 6 and 8 are fixed to the heat exchange plugs 5 and 7, and the heat of the heat generating device 1 is transferred to the heat exchange plug 5, and the heat is conducted from the heat exchange plug 7 to the cooling device 2.

  In FIG. 3A, 13 is a sealed container for constituting a heat pipe, and 14 is a sealed fluid sealed in the sealed container 13. The hermetic container 13 is made of copper, aluminum, or other metal having high thermal conductivity, and the sealed fluid 14 encloses a gas-liquid two-phase heat medium such as water or an aqueous alcohol solution. A wick such as a fiber or a sintered body can be accommodated in the sealed container 13. In this case, the sealed fluid 14 condensed at one end (condensing part) can travel along the wick and move to the other end side (evaporating part).

  With this configuration, the heat pipe in which the two-phase fluid is sealed has an action as shown in FIGS. When the heat connection portion 6 is inserted into the heat transfer socket 6a of the heat generating device 1 as shown in FIG. 3B, the heat of the heat generating electronic component transmitted to the heat transfer socket 6a is one end (evaporation) of the heat connection portion 6. Part) is thermally conducted to the sealed container 13. Then, the sealed fluid 14 near this receives heat and evaporates. The sealed fluid 14 in a vapor state expands and flows as a vapor flow to the other end side (condensing part), and is condensed by touching the sealed container 13 whose temperature is lowered by the action of the heat exchange plug 5. The sealed fluid 14, which has become liquid due to condensation, moves from the condensing unit to the evaporating unit as a liquid return flow in order to make up for the encapsulating fluid 14 in the evaporating unit whose liquid volume has decreased because the gas-liquid balance has been lost in the evaporating unit. At this time, it moves along the inner wall surface of the sealed container 13 as indicated by a broken line in FIG. 3B, or moves along a wick separately accommodated for this purpose. At the other end (condensing part) of the heat connection part 6, heat is conducted to the heat exchange plug 5 through the sealed container 13. When the heat pipe is used in this way, the heat transport limit can be improved as compared with the case where heat is transferred using a solid copper rod. Even when a refrigerant is selected, a higher heat transport limit may be obtained when an aqueous alcohol solution is used than when water is used. The heat conducted is further transferred to the cooling device 2 side through the heat transfer cable 3.

  Next, as shown in FIG. 3C, when the heat connection portion 8 is inserted into the heat transfer socket 8 a of the cooling device 2, the heat from the heat transfer cable 3 transmitted to the heat exchange plug 7 is heat. Heat is conducted to the sealed container 13 at one end (evaporating part) of the connection part 8. Then, the sealed fluid 14 near this receives heat and evaporates. The encapsulated fluid 14 in a vapor state expands and flows as a vapor flow to the other end side (condensing part), and is condensed by the action of the cooling device 2 serving as a low heat source. The condensed fluid 14 that has been condensed into a liquid is supplied as a liquid return flow from the condensing unit side to the evaporating unit in order to compensate for the encapsulating fluid 14 on the heat exchange plug 7 side whose liquid amount has decreased because the gas-liquid balance has been lost in the evaporating unit. Move to. At this time, it moves along the inner wall surface of the sealed container 13 or moves along the wick as shown by the broken line in FIG. At the other end of the heat connection portion 6, heat is conducted to the heat transfer socket 8 a through the sealed container 13. Thereby, the heat from the heat transfer cable 3 is transferred to the heat transfer socket 8a and is exhausted to the cooling device 2.

  Subsequently, the heat exchange plug 5 on the side of the heat generating device 1 will be described with reference to FIGS. 4, 5 </ b> A and 5 </ b> B. FIG. 4 is a perspective view of the entire heat exchange plug 5, and the heat exchange plug 5 has the following configuration.

  4 and 5 (a) and 5 (b), 15 is a narrow channel heat transfer section to which a pair of flexible fluid cable bodies 4 are connected to receive heat on the side of the heat generating device 1 and pass it to the refrigerant. , 16 is a Peltier element that exerts a heat pump action when energized, and 17 is a heat conduction block that receives a plurality of heat pipes, which are heat connection portions 6, in an outlet shape and receives heat from the heat generating device 1. The Peltier element 16 is for raising the temperature on the high heat side to a predetermined level in order to increase the heat transfer efficiency in the heat transfer cable 3, and in order to achieve high heat transfer efficiency, approximately the same amount of electric power as the amount of heat to be transferred is required. . Accordingly, if the amount of heat transferred through the heat transfer cable 3 is made as small as possible and the temperature difference between the heat transfer cables 3 is reduced, the required power can be reduced. This is the reason why a plurality of heat connection portions 6 and 8 (heat pipes) are used in the first embodiment. This condition is sufficiently satisfied when the temperature difference is small, such as exhaust heat treatment.

  Although the Peltier element 16 is not essential for the heat transfer cable 3, it is necessary for obtaining high heat transfer efficiency. Furthermore, the above-described heat conduction block 17 is made of a metal having a high thermal conductivity, such as copper or aluminum, and one end (condensation part) side of the plurality of heat connection parts 6 is fixed to the heat conduction block 17. On the other hand, the other end (evaporating part) side protruding a predetermined length is inserted into the heat transfer socket 6 a of the heat generating device 1.

  Next, the detail of the narrow flow path heat transfer part 15 is demonstrated based on Fig.5 (a) (b). The narrow channel heat transfer section 15 is connected to the pair of flexible fluid cable bodies 4 to form a U-shaped channel. As shown in FIGS. 5 (a) and 5 (b), the narrow channel heat transfer section 15 is provided with a separation wall that partially partitions the internal space to the left and right. Since the length of the separation wall is shorter than the length of the narrow flow passage heat transfer section 15 along the flow path direction and does not reach the opposing wall, the gap that is not partitioned by the separation wall is a flow in which the flow is reversed. It becomes a road. When the refrigerant on the back surface from one flexible fluid cable body 4 flows into the narrow channel heat transfer section 15, the heat is exchanged with the lower Peltier element 16, etc., and FIG. b) From the left and right chambers, for example, the left chamber, to the reversal channel, the refrigerant makes a U-turn and flows to the other chamber divided by the separation wall, for example, the right chamber, and is evaporated by heat exchange during this period. It flows out from the other flexible fluid cable body 4.

  By the way, when heat exchange is performed using a refrigerant having a low boiling point, the portion directly in contact with the Peltier element 16 or in some cases the heat conduction block 17 evaporates and is exhausted immediately with high heat. It evaporates immediately after inflow and enters a gas lock state. Therefore, it is difficult to perform heat exchange between the heat source and the refrigerant with high efficiency. Therefore, in the first embodiment, the flow path of the narrow flow path heat transfer unit 15 is separated into two layers on the heat generating device side and the back surface side, and a part of the refrigerant flowing through the low temperature side flow path is flown on the heat generating device side. The heat transfer surface is cooled by guiding it to the heat transfer surface. For this reason, the left and right two spaces of the part partitioned by the separation wall are further divided into two upper and lower layers, and a total of four in the AA cross section (see FIG. 5A) of the narrow channel heat transfer section 15. Separated into chambers. A separation wall is also provided in the flow path of the reversing flow path.

  5 (a) and 5 (b), 18a and 18b are non-heated sub-flow passages that are separated into the two layers described above and constitute two left and right chambers on the back side. In the non-heated sub-channels 18a and 18b, these two chambers are connected by a passage like a U-shape. One chamber, for example, the left chamber (non-heated subchannel 18a) in FIGS. 5 (a) and 5 (b) is connected to the flexible fluid cable body 4 and the liquid refrigerant flows into the right chamber (unheated subchannel). In 18b), it merges with a gas-liquid two-phase refrigerant or a gas refrigerant flowing out from a heating main flow path 19b described later, and flows out into the flexible fluid cable body 4. In addition, between the right chamber (non-heating sub-flow path 18b) on the outflow side of the non-heating sub-flow path and the flexible fluid cable body 4, the inside of the non-heating sub-flow paths 18a and 18b is heated within the heating main flow path 19a. A throttle for maintaining a higher pressure than 19b (described later) is provided, and the non-heating sub-flow channel 18a and the heating main flow channel 19b are connected to the cable body 4 after joining.

  And as demonstrated above, 19a, 19b is the heating main flow path which comprises the right and left two chambers used as the heat-emitting apparatus side among the said 2 layers. Non-heating sub-channels 18a and 18b are provided adjacent to surfaces other than the heat exchange side surfaces (heat transfer surfaces) of the heating main channels 19a and 19b. One chamber, for example, the left chamber (heated main channel 19a) is connected to the flexible fluid cable body 4 together with the non-heated subchannel 18a, and the liquid refrigerant flows into the other chamber, for example, the right chamber (for example, the right chamber ( The heating main flow path 19 b) and the non-heating sub flow path 18 b merge to cause the gas-liquid two-phase refrigerant or gas refrigerant to flow out to the flexible fluid cable body 4.

  Next, reference numeral 20 denotes a sintered plate (a leakage channel of the present invention) serving as a side plate and a central separation wall of the narrow channel heat transfer section 15 for supplying a cold refrigerant from the non-heating sub-channel 18 to the heating main channel 19. ). The sintered plate 20 is a sintered body such as aluminum, stainless steel, copper, brass, bronze, etc., and is porous, so that a non-heated side stream flows in such a manner that a leaking fluid flows as shown in FIG. The liquid refrigerant can be continuously and uniformly supplied from the passage 18 to the heating main passage 19. This flow is formed by the pressure difference between the non-heating sub-flow channel 18 and the heating main flow channel 19 due to, for example, a restriction provided between the flexible fluid cable body 4. In place of or in addition to the sintered plate 20 described above, in addition to this, a groove (groove) is formed on the surface of the heat transfer surface. Can also lead to. However, the groove formation has poor workability, increases the manufacturing cost, and it is difficult to provide uniform cooling performance, and a strong and weak cooling flow is apt to be formed. Therefore, it is easier to produce a uniform leakage flow by controlling the pores formed during the production of the sintered body, and cooling is effective because the liquid refrigerant oozes on the heat exchange side. It is preferable that the leakage channel is formed by a sintered body. The self-liquid supply cooling mechanism for cooling the heat transfer surface in the present invention is composed of a non-heating sub-channel 18 and a heating main channel 19, a sintered plate 20 or a leakage channel formed with a groove. is there.

  5 (a) and 5 (b), 21 is a heat exchange side surface (heat transfer surface of the present invention) of the heating main channel 19, and 22 is a channel partition wall (the present invention) that separates the non-heating sub-channel 18 and the heating main channel 19. Other than the heat transfer surface). The liquid refrigerant in the non-heated sub-channel 18 is continuously and uniformly supplied (exuded) to the heat exchange side surface 21 through the sintered plate 20 and directly contacts the Peltier element 16 or the heat conduction block 17. The self-liquid is supplied to the part where it is, and the exhaustion by the rapid evaporation of the refrigerant is suppressed. The flow shown by the arrows in FIG. 5B shows the state of the cooling flow by the supply of the liquid refrigerant by the self liquid. The amount of liquid refrigerant leakage (self-liquid supply amount) can be controlled by the pressure difference between the non-heated sub-channels 18a and 18b and the heating main channels 19a and 19b.

  Subsequently, the heat exchange plug 7 on the cooling device 2 side will be described with reference to FIGS. The typical heat exchange plug 7 includes two types, a pump loop type heat exchange plug 7 as shown in FIG. 7A and a refrigeration cycle type heat exchange plug 7 as shown in FIG. 8A. is there. First, the pump loop type heat exchange plug 7 will be described with reference to FIG. FIG. 6A is an overall perspective view of a pump loop type heat exchange plug 7, and the heat exchange plug 7 has the following configuration. In FIG. 6A, reference numeral 23 denotes a heat conduction block that transfers heat to the cooling device 2 by supporting a plurality of heat pipes, which are the heat connection portions 8, in an outlet shape. Similarly to the heat conduction block 17, the heat conduction block 23 is made of a metal having a high thermal conductivity, such as copper or aluminum. One end (condensation part) side of the plurality of heat connection parts 6 is fixed to the heat conduction block 23, while the other end side protruding in a cantilever shape by a predetermined length is inserted into the heat transfer socket 8 a of the cooling device 2.

  Reference numeral 24 denotes a condensing unit that performs a condensing function of a cooling circuit (see FIG. 7A) using a heat cycle of the refrigerant. The gas refrigerant sent via the heat transfer cable 3 condenses in the condensing unit 24 provided in contact with the heat conduction block 17 and returns to the liquid refrigerant. The heat conduction block 17 is maintained at a low temperature by fitting the heat connection portion 8 and the heat transfer socket 8a of the cooling device 2 together.

  Since the liquid refrigerant is circulated through the cooling circuit, the liquid refrigerant is sent to a portion provided in the heat exchange plug 7 to be described next. Reference numeral 25 denotes a tank-like gas-liquid separator that separates vapor that has not been condensed and returned to liquid into gas-liquid separation. Refrigerant can also be supplied from the gas-liquid separator 25. When the vapor is mixed in the refrigerant, a compressible fluid is mixed in the pump, so that the pump operation becomes impossible. The gas-liquid separator 25 avoids this.

  Furthermore, 26 shown in the cooling circuit of FIG. 7A and the configuration diagram of FIG. 6A is a circulation pump for circulating the refrigerant in the cooling circuit. It may be a turbo type, a rotary type, or a reciprocating type. It is the liquid refrigerant that is pressurized by the circulation pump 26. The refrigerant is sent to the heat exchange plug 5 through one of the paired heat transfer cables 3 and is vaporized by the narrow channel heat transfer section 15, so that the gas-liquid two-phase refrigerant or the gas refrigerant is paired with the heat transfer cable 3. The other is sent to the heat exchange plug 7. In addition, since the circulation pump 26 and the gas-liquid separator 25 are provided in the heat exchange plug 7, the heat exchange plug 5 is balanced in size, and the heat transfer cable 3 is compact and clean. Of course, you may install the circulation pump 26 and the gas-liquid separator 25 separately.

  3A, 3B, and 3C, the heat exchange plugs 5 and 7 are thermally connected to the high heat source and the low heat source via the heat transfer sockets 6a and 8a. The cooling circuit is configured by the heat transfer cable unit of the first embodiment as a physical configuration. FIG. 7B is a basic cooling circuit diagram in which only the elements of FIG. 7A are extracted.

  Next, the heat exchange plug 7 using a refrigeration cycle type cooling circuit will be described with reference to FIGS. 6 (b), 8 (a) and 8 (b). Since the heat connecting part 8, the heat conduction block 23, the condensing part 24, etc. are not different from the basic functions of the pump loop type heat exchange plug 7, detailed description thereof will be omitted. In FIG. 6B, reference numeral 27 denotes a compressor. A reciprocating type, a turbo type, or a rotating type may be used. Reference numeral 28 denotes an expansion portion such as an expansion valve or a flow resistor. The compressor 27 and the expansion part 28 provided in this heat exchange plug 7 bear the functions of the compressor and the expansion part, which are the components of the basic cooling circuit shown in FIG. 8B.

  Now, the heat transfer by the refrigeration cycle type cooling circuit operates as shown in FIG. The gas refrigerant passes through one of the heat transfer cables 3 and flows into the compressor 27 where it is compressed. Next, it is cooled by the condensing unit 24 and is wholly or partially condensed to become a liquid refrigerant or a gas-liquid two-phase refrigerant, and expands in the expansion unit 28. Here, the liquid refrigerant or the gas-liquid two-phase refrigerant whose isoenthalpy has changed is sent to the heat exchange plug 5 on the side of the heat generating device 1 through the other side of the heat transfer cable 3. On the heat generating device 1 side, the liquid refrigerant or the gas-liquid two-phase refrigerant evaporates when passing through the narrow channel heat transfer section 15 and returns to the compressor 27 again through the heat transfer cable 3 as a gas refrigerant. In other respects, it is basically the same as the pump loop type heat transfer. By providing the refrigerant compression process, the heat radiation temperature can be raised, and thereby a larger heat radiation amount can be secured, thereby moving a larger amount of heat from the heat generating device 1 or the temperature level of the heat generating device 1. Can be made lower. That is, the range of the operating pressure and the operating temperature level of the heat transfer system can be expanded from the pump loop type cooling circuit.

  FIGS. 9A and 9B illustrate the temperature transition in the heat dissipation process. FIG. 9A is an example of a temperature transition when cooled by the heat transfer system of the first embodiment. A semiconductor chip is used as a heat generating electronic component, a personal computer is used as a heat generating device 1, a heat pipe is used as a heat connecting portion, and a cooling device 2 is shown. The case where the small cooling part 2b (fan) shown in 1 is used is shown.

  Heat generated from the semiconductor chip is transferred to the heat transfer socket 6a using a heat transfer process in the personal computer. This heat is received from one end (evaporation part) of the heat pipe (heat connection part 6) of the heat exchange plug 5 from the heat transfer socket 6a, and is radiated at the other end (condensation part) side, and at the same time by the Peltier element 16 Heated to temperature. Thereafter, heat is transferred by the heat conduction block 17 and the narrow channel heat transfer section 15, and is transferred by the heat transfer cable 3 to the heat exchange plug 5 inserted in the small cooling section.

  In the heat exchange plug 5, the heat transferred via the heat transfer cable 3 by the condensing action in the condensing unit 24 is transferred to the heat conduction block 23 and the heat pipe (heat connection unit 8), and from this heat pipe to the heat transfer socket 8 a. Heat conduction. Further, the small cooling section (fan) provided with the heat transfer socket 8a is cooled to the ambient air temperature by heat exchange with the outside air.

  FIG. 9B shows the temperature transition when the large cooling device 2a shown in FIG. 1 is used as the cooling device 2, and the temperature transition process when the heat generated from the semiconductor chip is intensively cooled by the large cooling device 2a. Show. The cooling by the large cooling device 2 is based on the cooling circuit of FIG. When the heat transfer cable unit of the first embodiment is used, only the electric power for the Peltier element and the small electric power for driving the small fan are required, but the large cooling device 2a as a comparative example has a built-in compressor and a large electric power. A relatively large amount of power is required to drive the fan. The operation of the refrigeration cycle by this compressor is independent of whether or not the refrigeration cycle type circuit of FIG. 8A is adopted as the heat transfer cable 3, and the heat transfer cable 3 is shown in FIG. A pump loop type circuit may be employed. Of course, instead of the large cooling device 2a, a small cooling device 2b using only a fan can be connected to directly radiate heat to the outside air.

  That is, in Example 1, when the same semiconductor chip is dissipated, it is possible to perform cooling equivalent to that of the large cooling device 2 only by supplying a small amount of power. In addition, the heat transfer cable 3 and the heat transfer cable unit can be used to connect to an external cooling device 2 separately installed at an arbitrary place through a free path. Noise can be prevented indoors, and dust prevention and temperature environment can be maintained by eliminating air cooling fans.

  In addition, if the heat transfer cable 3 is standardized (standardized) in advance, anyone can assemble the same heat transfer system with the standardized heat transfer cable 3, which is versatile and can exhaust heat from all heat generating devices externally. The cooling device 2 can be transferred. In this way, a network-type heat transfer system can be freely constructed using the heat transfer cable 3 just as in the case of constructing a control system and a communication system with a conventional electric cable.

  And this doesn't stop at a heat transfer system for waste heat. It can be used in a general-purpose heat transfer system that transfers heat from a high heat source to a low heat source with high heat transfer efficiency, and the transferred heat can be reused in a low heat source. And this heat source may be installed anywhere, and the freedom degree of design increases. Therefore, unified heat use and heat dissipation including peripheral heat generating devices can be performed, and the construction of a heat transfer system as an infrastructure can be very easily performed. At this time, the standardized heat transfer cable 3 and heat transfer cable unit support the heat transfer system as a basic technology. FIG. 12 shows a state in which heat is freely used by using the heat transfer cable 3 standardized (standardized) in the office or home. This will be further described later.

  10 and 11 show an example of a heat transfer system using such a heat transfer cable unit. FIG. 9 shows a case of a heat transfer system in a factory. Conventionally, as shown in the upper diagram of FIG. 10, for example, it was natural to install a boiler and a heat generating device at the same time. A heat transfer system using waste heat can be easily created using the unit.

  FIG. 11 shows an energy saving system in the home. When the air conditioner and the refrigerator are installed in the same room, the air must be cooled as shown in the upper diagram of FIG. 11, which is extremely inefficient from a thermal viewpoint. If this is cooled by the external cooling device 2 as shown in the figure below using a heat transfer cable unit, the arrangement can be easily made highly efficient. Although each of these is small, if a large number of people gather, it will greatly serve energy conservation.

  Also, as shown in FIG. 12, in order to use the heat transfer cable of Example 1, the heat transfer cable unit, a collective heat transfer socket 29 is provided on the wall surface of the office or home as well as an electrical wiring socket, It is preferable to thermally connect the collective heat transfer socket 29 to an external low heat source or a high heat source of another system. This low heat source and high heat source should be developed as social infrastructure. When releasing the heat from the indoor heat source to the outside, the heat from the indoor high heat source is discharged to the outdoor low heat source via the heat transfer cable and the collective heat transfer socket 29 provided on the wall surface to supply the heat indoors. When doing so, the collective heat transfer socket 29 is provided in an indoor low heat source to supply heat from an external high heat source. The user simply inserts the heat exchange plug 7 of the heat transfer cable 3 into the collective heat transfer socket 29. The collective heat transfer socket 29 and the heat transfer cable 3 can greatly change the social form of heat utilization like current electricity utilization.

  Thus, the heat transfer cable, the heat transfer cable unit, the heat transfer system, and the heat transfer system construction method according to the first embodiment of the present invention perform heat transfer using a heat transfer cable that can be standardized, and are extremely simple, easy and quick. It is possible to construct a heat transfer system that can transfer heat. According to this heat transfer system, heat can be transferred from any heat generating device, and heat can be reused to contribute to energy saving. Since it can be freely connected to a cooling device placed in any external environment, it contributes to the prevention of noise indoors where secondary heating equipment is installed, the prevention of dust by eliminating air cooling fans, and the maintenance of the temperature environment. In addition, the standardized heat transfer cable unit is inexpensive and can completely change the conventional form of heat utilization.

  The present invention can be applied to a heat transfer cable unit including a flexible fluid cable and a heat transfer socket, and a heat transfer system using the heat transfer cable unit.
