Description

  The present invention relates to a cooling device that cools a cooling target such as a heating element or a heating element having a curved heat radiation surface.

  Conventionally, a cooling device that cools an object to be cooled, such as a heating element or a heating element having a curved heat radiating surface, contacts and fixes the cooling device and the heating element sufficiently to secure a heat radiation area. There is a technique of bringing a curved surface into contact with the surface (for example, see Patent Document 1).

  Further, some cooling structural members (cooling devices) circulate coolant in pipes (pipes) (see, for example, Patent Document 2). In addition, there exists what has arrange | positioned the buffer member between the cooler (cooling device) and the sample (cooling object) (for example, refer patent document 3).

  In general, in the case of air cooling, cooling can be performed without being greatly affected by the shape of the heat radiating surface, but a large blower is required according to the amount of heat generation, and it is not possible to cope with one having a high heat generation amount. In the case of liquid cooling, it is said that the cooling capacity is higher than that of air cooling. However, in the case of an external cooling device that cools a cooling target such as a heating element or a heating element having a curved heat dissipation surface, heat dissipation of the heating element is performed. If the surface is a curved surface, the point of contact or line contact between the heat dissipation surface and the endothermic surface of the cooling device will reduce the heat exchange area and reduce the cooling capacity. It is considered important.

Embodiment 1 FIG.
Embodiment 1 of the present invention will be described below with reference to FIGS. 3A is a cross-sectional view of the cooling part (cooling plate) in the cross section B indicated by the one-dot chain line in FIG. 2, and FIG. 3B is a cross-sectional view of the cooling part (cooling plate) in the cross section C indicated by the one-dot chain line in FIG. 4 is a cross-sectional view of the cooling unit (cooling plate) in the cross-section A indicated by the one-dot chain line in FIG. 1, and FIG. 5 is a perspective view of the cooling target and the cooling unit (cooling plate) wound around the cooling target. FIG. 6 is a perspective view seen from the other side of the cooling target and the cooling part (cooling plate) wound around the cooling target.

  1 to 8, reference numeral 0 denotes a cooling target (cooling target, heating element, heating element) that is an object to be cooled by the cooling device according to the present application. The object 0 to be cooled is schematically illustrated except for the surface (part) in contact with the cooling device according to the first embodiment. 1 is a cooling plate, 2 is a flow path formed inside the cooling plate and through which a refrigerant passes. The refrigerant delivered (conveyed, flowing) inside the flow path 2 may be a general refrigerant. The refrigerant includes refrigerant liquid. 3 is a curved surface portion formed on one surface of the cooling plate 1, 4 is a cooling portion composed of the cooling plate 1, the flow path 2, and the curved surface portion 3. The cooling unit 4 may include a heat conduction member 3 s described later in addition to the cooling plate 1, the flow path 2, and the curved surface part 3. The heat conductive member 3s may be used as an absorption margin of a gap between the cooling unit 4 and the cooling target 0. In the drawings, the same reference numerals denote the same or corresponding parts, and detailed descriptions thereof are omitted.

  The cooling plate 1 is configured by overlapping a first plate (upper plate) 1a and a second plate (lower plate) 1b which are formed of flat plates having good thermal conductivity. The first plate 1a and the second plate 1b are fixed by a fastener (fastening screw) 1c. In the present application, the case where the first plate 1a and the second plate 1b are formed of a metal flat plate will be described as an example, but the present invention is not limited thereto. A fastening hole (fastening screw hole) 1d for the fastener 1c is formed in the first plate 1a and the second plate 1b. The cooling plate 1 is configured by overlapping a first plate 1a and a second plate 1b. In the drawings, the same reference numerals denote the same or corresponding parts, and detailed descriptions thereof are omitted.

  The curved surface portion 3 is formed on the surface of the first plate 1a opposite to the second plate 1b. The flow path 2 includes the surface of the first plate 1a and the second plate 1b including those formed between the plurality of fins 1f formed on the first plate 1a and the surface of the second plate 1b. And a space formed between the surface and an opening 2w formed in the cooling plate 1 (first plate 1a). In other words, the flow path 2 and the opening 2w are in communication with each other, and the portion sandwiched between the plurality of fins 1f is also referred to as the flow path 2. In the drawings, the same reference numerals denote the same or corresponding parts, and detailed descriptions thereof are omitted.

  The flow path 2 may be formed between the plurality of fins 1f formed on the first plate 1a and the depressions provided on the surface of the second plate 1b. The curved surface portion 3 may be brought into contact with the object to be cooled 0 through a heat conducting member 3s having flexibility (flexibility). The object to be cooled 0 is a heating element such as a heating element or a heating element having a curved heat radiating surface or a heating element. When the curved surface of the curved surface portion 3 and the curved surface to be cooled can sufficiently come into contact with each other, the heat conducting member 3s may not be used. In the drawings, the same reference numerals denote the same or corresponding parts, and detailed descriptions thereof are omitted.

  When the object 0 to be cooled is placed or pressed, the heat conducting member 3 s has a surface that contacts the object 0 to be deformed into a curved surface, or the curvature of the curved surface. Any heat conductive member 3 s may be used as long as the surface to be cooled 0 is placed or pressed against the curved surface having the same curvature. The curved surface of the heat conducting member 3s may be a curved surface generated by placing the heat conducting member 3s on the curved surface portion 3. This means that the heat conducting member 3 s is bent along the curved surface of the curved surface portion 3. In the drawings, the same reference numerals denote the same or corresponding parts, and detailed descriptions thereof are omitted.

  In the present application, “contact” and “pressing” are used synonymously. This is because there are a case where only the cooling unit 4 is brought into contact with the cooling target 0 and a case where the cooling unit 4 is pressed in contact. In the case of pressing in contact, the fixing unit 7, the fixing unit (fixing screw) 7 a, the fixing unit (fixing guide) 7 b, and the fixing unit (fixing belt) 8 are used as the cooling target 4. Or a case where the cooling object 0 is pressed against the cooling unit 4 by its own weight.

  Moreover, you may consider heat conductive member 3s as a part of curved-surface part 3 (cooling part 4). In this case, the curved surface portion 3 becomes a “curved surface portion on which the heat conducting member 3 s is formed” or “a flat portion on which the heat conducting member 3 s is formed”. In the former case, the surface of the cooling plate in contact with the heat conducting member is a curved surface having a curvature equal to or less than the curvature of the heat conducting member 3s by the cooling object 0 described above or less than the curvature originally possessed by the heat conducting member 3s ( The curved surface portion 3) is better. When the cooling target 0 is placed on the cooling unit 4, the thickness and shape of the heat conducting member 3s may be selected in consideration of the importance of the cooling target 0. In the drawings, the same reference numerals denote the same or corresponding parts, and detailed descriptions thereof are omitted.

  Subsequently, in FIGS. 1 to 8, 5 is a plurality of pipes that connect the flow paths 2 of the cooling plate 1 through the openings 2 w of the cooling plate 1, and 6 is formed by the flow path 2 and the piping 5. A pump connected to the delivery side and the inflow side in the refrigerant circulation path, which cools the refrigerant flowing in from the inflow side and sends it out from the delivery side, and the pump 6 has a pump function for sending the refrigerant and a cooling function for cooling the refrigerant. Since only one function is required, the pump function and the cooling function may be separate. Reference numeral 7 denotes a fixing tool for fixing an object to be cooled, and the fixing tool 7a is a fixing screw that is inserted from the surface side of the second plate 1b on the opposite side to the first plate 1a and fixes the cooling plate 1. The fixing tool 7b is a fixing guide capable of fixing a cooling target placed on the curved surface portion 3. Reference numeral 8 denotes a fixing portion (fixing belt) for arranging a plurality of cooling plates 1 in an annular shape with the curved surface portion 3 facing inward, fixing the plurality of cooling plates to each other, and fixing a cooling target. In the drawings, the same reference numerals denote the same or corresponding parts, and detailed descriptions thereof are omitted.

  The configuration of the cooling device (external liquid cooling device) according to Embodiment 1 is shown in FIG. The cooling unit 4 of the cooling device according to the first embodiment provides the flow path 2 inside the metal flat plate by the first plate 1a and the second plate 1b, and performs heat exchange between the refrigerant flowing inside and the metal flat plate. . By forming the fin 1f on the first plate 1a side between the metal flat plates, the cooling efficiency for the object to be cooled can be further increased. The flow path 2 is connected to the pump 6 that cools the refrigerant through the opening 2w by a pipe 5, and the refrigerant circulates. Although the opening 2w is illustrated as being drilled in the first plate 1a, the opening 2w may be drilled in the second plate 2a and communicated with the flow path 2, and the opening 2w The dent provided in the plate 1a and the dent provided in the second plate 1b may be formed by overlapping the first plate 1a and the second plate 1b.

  As an example of the cooling plate 1, FIG.2 and FIG.3 is shown. The cooled refrigerant is sent out from the pump 6 and flows into the flow path 2 through the pipe 5 and the opening 2w. The refrigerant takes heat from the object to be cooled on the curved surface portion 3 of the cooling portion 4 by heat exchange in the process of passing through the plurality of elongated channels 2 sandwiched between the plurality of fins 1f, and is opposite to the flow-in opening 2w. And is returned to the pump 6 via the pipe 5 and cooled by the pump 6. Due to the heat exchange, the refrigerant in the inflow side opening 2w has a low temperature, and the refrigerant in the outflow side opening 2w has a high temperature.

  In the channel 2, a space corresponding to the front chamber is formed between the elongated portions (plurality) sandwiched between the plurality of fins 1 f and the opening 2 w inside the cooling unit 4, and the space and the opening 2 w Communicate. Moreover, in the cooling device according to the first embodiment, the pipe 5 has the flexibility (flexibility) for the pipe 5, so that the pipe 5 has the space between the pump 6 through which the refrigerant circulates and the cooling section 4. Since the pipe 5 can be deformed within a flexible range, the degree of freedom of installation is increased.

  The cooling plate 1 is formed by overlapping the first plate 1a and the second plate 1b and fixed by a fastener 1c or the like, the refrigerant flows through the internal flow path 2, and further, as described above, the heat absorbing surface (curved surface portion). 3) The fins 1f are provided on the first plate 1a having the structure, and the heads of the fastening screws (fasteners) 1c are provided at the four corners of the second plate 1b having a structure capable of promoting heat exchange between the refrigerant and the cooling plate 1. By disposing the fastening screws 1 c so as not to protrude from the curved surface portion 3, the cooling plate 1 can be configured without reducing the effective area for cooling the curved surface portion 3. As shown in FIG. 2, notches and depressions may be formed at the four corners of the second plate 1b so that the head of the fastening screw 1c is hidden.

  The heat conductive member 3s is formed on the curved surface portion 3 of the cooling device according to the first embodiment. Specifically, the heat absorbing surface (curved surface portion 3) of the cooling plate 1 is made of a flexible and highly heat conductive material. Even when the curved surface portion 3 and the heat radiation surface (curved surface) of the object to be cooled 0 do not coincide with each other by adhering or closely adhering a certain heat conducting member 3s, the flexible heat conducting member 3s is a buffer material. Become. Therefore, as shown in FIG. 4, there is almost no gap between the curved surface portion 3 of the cooling unit 4 and the heat radiating surface of the cooling target 0, and the heat of the cooling target 0 is efficiently radiated through the heat conducting member 3s. .

  That is, even if there is a difference in the shape of the heat radiation surface of the cooling target 0 and the curved surface portion 3 by the heat conduction member 3s, the heat conduction member 3s can absorb the shape of the heat radiation surface of the cooling target 0 to some extent. Fine positioning between the heat-radiating surface and the heat-absorbing surface (curved surface portion 3) is unnecessary, and a sufficient contact area can be secured at all times, and a stable cooling capacity can be obtained. Further, in addition to the curved surface, even in the case of a surface having an uneven shape, the heat conductive member 3s enters the uneven space, whereby the contact area can be increased, and sufficient heat exchange can be expected. Since the contact surface of the heat conducting member 3s with the heat radiating surface of the object to be cooled 0 has non-adhesive properties, the cooling device according to the first embodiment is brought into contact and cooled only when necessary, and is unnecessary. Sometimes it can be removed.

  When the heat generation amount of the cooling object 0 that is the object to be cooled by the cooling device according to the first embodiment is larger, the thermal resistance of the heat conducting member 3s is higher than that of the cooling plate 1 that is a metal (heat conducting member). Therefore, the thermal resistance is reduced by bringing the shape of the curved surface portion 3 of the cooling plate 1 closer to the shape of the heat radiating surface of the object to be cooled 0, reducing the thickness of the heat conducting member 3s, and contacting or placing it. Cooling capacity can be improved.

  In particular, the surface of the cooling plate in contact with the heat conducting member has a curved surface (curved surface portion 3) having a curvature equal to or less than the curvature of the heat conducting member 3s according to the object to be cooled 0 or less than the curvature originally possessed by the heat conducting member 3s. 4), as described in FIG. 4, it is possible to reduce the bending at the end portion (edge) of the heat conducting member 3 s, thereby further ensuring the contact between the cooling target 0 and the heat conducting member 3 s. be able to. This is because the distance between the curved surface portion 3 and the heat conducting member 3s increases toward the end portion (edge) of the heat conducting member 3s, and a space can be created as a refuge for the crushed heat conducting member 3s. It is.

  The cooling device according to the first embodiment can be easily operated regardless of the curved surface shape on the heat radiating surface side by adhering a flexible high heat conductive material (the heat conducting member 3s) to the heat absorbing surface of the cooling device. It is. In addition, the cooling device according to Embodiment 1 can be easily operated with respect to a heating element having a high calorific value that cannot be handled by air cooling.

  Here, the case where the cooling target 0 is fixed to the cooling plate 1 by the cooling device according to the first embodiment will be described. First, the fixing mode by the fixing portion (fixing belt) 8 will be described with reference to FIGS. 5 and 6, and then the fixing tool (fixing screw) 7 a or the fixing tool (fixing screw ( A fixing mode by the fixing guide 7b will be described. In any of the fixing modes, if the heat conducting member 3s having flexibility is used, the heat conducting member 3s is deformed and fills an appropriate gap between the cooling plate 1 and the cooling target 0, so that the cooling plate 1 and the cooling target are used. Strict positioning with zero is not necessary, and a stable cooling capacity can always be exhibited.

  First, with reference to FIG. 5 and FIG. 6, a fixing mode by the fixing portion (fixing belt) 8 will be described. As shown in FIG.5 and FIG.6, it fixes to the back surface of the cooling part 4 (The surface opposite to the cooling object side of the cooling plate 1, the surface opposite to the surface which contacts the 1st board 1b in the 2nd board 1b). A structure that allows the belt 8 to pass therethrough is provided. Thereby, when the cooling target 0 is a columnar one, a plurality of cooling units 4 (four in FIG. 5 and FIG. 6 but not limited thereto) are arranged around the cooling target 0, Since the plurality of cooling units 4 can be fixed to the cooling target 0 by binding the cooling target 0 with the fixing belt 8 including the plurality of cooling units 4, the cooling target 0 can be cooled from the periphery.

  As shown in FIGS. 5 and 6, the cooling unit 4 a, the cooling unit 4 b, the cooling unit 4 c, and the cooling unit 4 d, which are a plurality of cooling units 4, are connected by a pipe 5, respectively. The part 4 d and the pump 6 are also connected by a pipe 5. The refrigerant cooled by the pump 6 is delivered to the cooling unit 4a → the piping 5 → the cooling unit 4b → the piping 5 → the cooling unit 4c → the piping 5 → the cooling unit 4d, and by heat exchange, the cooling unit 4a and the cooling unit 4b, respectively. Heat is taken from the cooling target 0 on the curved surface portion 3 of the cooling unit 4c and the cooling unit 4d, and the refrigerant returns from the cooling unit 4d to the pump 6 through the pipe 5.

  For this reason, since the refrigerant goes from a low temperature to a high temperature in the process of delivery, if the degree of heat exchange in the cooling unit 4d is sometimes low, the length of the pipe 5 is increased so that the heat is radiated from the pipe. 5 and FIG. 6 may be wound in two rows around the object to be cooled so that the flow of the refrigerant falls within the range between one and the other.

  In addition, by using a pipe 5 having flexibility (flexibility), the pipe 5 is within a flexible range in which the pipe 5 has between the pump 6 through which the refrigerant circulates and between the cooling parts 4. Since the object to be cooled is bound by the fixing belt 8, the pipe 5 is deformed even when the distance between the cooling part 4a, the cooling part 4b, the cooling part 4c, and the cooling part 4d changes greatly. Thus, adverse effects due to changes in the distance between the cooling unit 4a, the cooling unit 4b, the cooling unit 4c, and the cooling unit 4d can be reduced.

  5 and 6, a plurality of cooling units 4 are arranged in an annular shape with the curved surface portion 3 facing inward, and the plurality of cooling units 4 (cooling unit 4a, cooling unit 4b, cooling unit 4c, cooling unit 4d). It can also be said that the cooling target 0 is fixed by the fixing portion 8 that fixes the two. Further, FIG. 5 illustrates the connection of the pump 6 → the pipe 5 → the cooling unit 4a, the cooling unit 4b → the pipe 5 → the cooling unit 4c, and the cooling unit 4d → the pipe 5 → the pipe 5 of the pump 6. FIG. 6 illustrates the connection of the piping 5 of the cooling unit 4a → the piping 5 → the cooling unit 4b and the cooling unit 4c → the piping 5 → the cooling unit 4d. That is, FIG.5 and FIG.6 is the perspective view seen from one side and the other of the cooling target 0. FIG.

  Of course, one cooling unit 4 may be fixed to the object to be cooled 0 by the fixing belt 8. However, in this case, the fixing belt 8 is prevented from coming into direct contact with the object 0 to be cooled, or when it is in contact, the portion where the object 0 to be cooled and the fixing belt 8 are in contact with the fixing belt 8. It is necessary to use a heat-resistant material for the fixing belt 8 or a temperature that does not adversely affect the fixing belt 8.

  Next, with reference to FIG. 7 and FIG. 8, a fixing mode by the fixing tool (fixing screw) 7 a or the fixing tool (fixing guide) 7 b will be described. As shown in FIG. 7, by providing attachment holes such as fixing screws 7a in the cooling unit 4, the fixing unit 7a can be attached when necessary to fix the cooling unit 4 to the object to be cooled 0 (posture support). As shown in FIG. 7, by sharing (integrating) the fixing screw 7a and the fastening screw 1c, it is possible to share (integrate) both the mounting hole of the fixing screw 7a and the fastening screw hole 1d. The area of the portion 3 (flat portion 3) and the heat conducting member 3s can be increased.

  Further, by providing mounting holes such as the fixing screw 7a (fastening screw 1c) on the heat radiating surface of the cooling target 0, the fixing screw 7a (fastening screw 1c) is inserted into the cooling target 0 to be stronger. It may be fixed. In other words, it can be said that the cooling unit 4 shown in FIG. 6 is fixed to the object to be cooled 0 by the fixture 7a inserted from the surface side on the opposite side to the first plate 1a in the second plate 1b. .

  As shown in FIG. 8, it can be said that the cooling unit 4 is fixed to the cooling target 0 by the fixing guide 7b by providing the fixing guide 7b in advance on the cooling target 0 or the cooling unit 4. When the fixing guide 7b is formed on the cooling target 0, the cooling target 0 can be cooled by inserting the cooling unit 4 between the two fixing guides 7b when necessary. In the case where the fixing guide 7b is formed in the cooling part 4, the cooling to be placed on the curved surface part 3 by providing an attachment hole for the fixing guide 7b or an attachment groove for the fixing guide 7b on the heat radiating surface of the object 0 to be cooled. It is possible to fix the target 0 or the cooling target 0 to be pressed against the curved surface portion 3.

  The cooling device according to the first embodiment includes a cooling unit 4 formed inside the cooling plate 1 and including a flow path 2 through which a refrigerant passes and a heat conduction member 3s having flexibility formed on one surface of the cooling plate 1. It can be said that it was prepared.

Embodiment 2. FIG.

  9 to 13, reference numeral 9 denotes a support portion (in which a plurality of cooling portions 4 are arranged in a matrix) and one of at least two cooling portions 4 (cooling plate 1) is inclined and supported with respect to the other. The cooling unit 4 (cooling plate 1) is inclined with respect to one of the at least two cooling units 4 (cooling plate 1) with respect to the other on the heat radiation surface (curved surface) of the large cooling target 0 by the support unit 9 and the support unit 9. ). Reference numeral 10 denotes an elevating unit which is formed on the side opposite to the side where the cooling unit 4 is formed of the support unit 9 and can raise and lower the support unit 9 to change the distance between the cooling unit 4 and the object 0 to be cooled. . In the drawings, the same reference numerals denote the same or corresponding parts, and detailed descriptions thereof are omitted.

  The elevating unit 10 may be any general elevating mechanism such as a jack or winch. Further, when the cooling unit 4 does not bear the weight of the cooling target 0 during cooling, the lifting unit 10 may be simple. In the present application, the shape of the elevating unit 10 is schematically illustrated. Moreover, the raising / lowering part as used in this application does not simply move up and down, but points out the mechanism which can change the distance of the cooling part 4 and the cooling object 0. FIG. That is, the elevating unit 10 may be referred to as the telescopic unit 10.

  The flow paths 2 of the plurality of cooling units 4 are connected to each other by pipes 5. Also in the cooling device according to the second embodiment, by using a pipe 5 having flexibility (flexibility), the pipe 5 can have a space between the pump 6 through which the refrigerant circulates and between the cooling sections 4. Since the pipe 5 can be deformed within the flexibility range, the degree of freedom of installation is increased.

You can simulate a board. Moreover, the curved surface corresponding to the curved surface which is the heat radiating surface of the object 0 to be cooled can be obtained by supporting one of the two cooling units 4 while being inclined with respect to the other. And the whole heat radiating surface can be cooled by making these cooling plate 1 (cooling part 4) groups contact the heat radiating surface of the cooling object 0. FIG.

  As shown in FIG. 9, the number of the cooling units 4 is not only three in the row direction and three in the column direction, but also according to the size of the cooling target 0 and the cooling unit 1 (cooling unit 4). It can be selected as appropriate, and can cope with a large heat dissipation surface by increasing the number of cooling plates in addition to an increase in the size of the cooling plate, and more compact cooling units 4 for a heat dissipation surface having a complicated shape. It can respond by using. A support portion 9 (base 9) is provided in consideration of the shape of the heat dissipation surface of the cooling target 0. That is, the support portion 9 is formed with a linearly simulated structure of a curved surface that is a heat dissipation surface of the cooling target 0 or a curved surface that is the same as the curved surface that is the heat dissipation surface of the cooling target 0. 9 and 10 show a support portion 9 (base 9) having a linearly simulated structure of a curved surface that is a heat radiating surface of the object 0 to be cooled.

  In FIG. 10, the elevating mechanism (elevating unit 10) for contacting the heat radiating surface of the cooling target 0 is not formed for each of the plurality of cooling units 4, but the supporting unit 9 considering the shape of the heat radiating surface of the cooling target 0 is used. (Stand 9) is provided, and a plurality of cooling units 4 are installed thereon (FIGS. 9 and 10A), and only the support unit 9 is pushed up by the lifting unit 10, so that the entire cooling plate 1 (cooling unit 4) is provided. ) Can be contacted simultaneously (FIG. 10B). Of course, an elevating mechanism (elevating unit 10) that makes contact with the heat radiating surface of the cooling target 0 may be formed for each of the plurality of cooling units 4 provided, but the elevating unit 10 shown in FIGS. 9 and 10 is used. Thus, the push-up structure of the plurality of cooling units 4 is simplified, and the cooling unit 4 can be easily attached to and detached from the cooling target 0.

  Furthermore, since the support portion 9 (the gantry 9) is provided in consideration of the shape of the heat radiating surface of the cooling target 0, it is easy to unify the shape of the cooling portion 4, so that the manufacturing cost of the cooling portion 4 can be reduced. . Further, the shape of the support portion 9 is made to correspond to the shape of the heat radiating surface, and when the cooling target 0 is placed or pressed, the surface that contacts the cooling target 0 is deformed into a curved surface, Alternatively, if the heat conducting member 3s has a curved surface having the same curvature as that of the curved surface, the heat conducting member 3s has a surface on which the cooling target 0 is placed or pressed, the thickness of the heat conducting member 3s is reduced. By reducing the thermal resistance, a higher cooling capacity can be obtained.

  FIG. 10 shows an example of a pipe 5 connection structure that connects a plurality of cooling units 4. FIG. 10A is an example in which a plurality of cooling units 4 are connected in series by pipes 5, and the temperature in the simulated large cooling plate is changed along the route of the pipes 5 from the inlet to the outlet. The temperature rises. Therefore, the cooling unit 4 that is brought into contact with the portion where the temperature of the heat dissipation surface of the cooling target 0 is high is connected so as to be in the vicinity of the outlet of the pipe 5, and the cooling unit 4 that is brought into contact with the portion where the temperature of the heat dissipation surface is relatively low is connected to the pipe. If it connects so that it may become 5 inlet_port | entrance vicinity, it can cool efficiently.

  On the other hand, in FIG. 10B, by connecting a plurality of cooling units 4 in parallel by the pipe 5, the temperature distribution of the refrigerant in the simulated large cooling plate becomes low on the inlet side and high on the outlet side. The cooling device has a structure simulating one large cooling plate having the same shape as the portion 4. As described above, it is possible to efficiently perform the cooling by determining the connection of the pipe 5 between the cooling units 4 according to the temperature distribution of the heat radiating surface of the cooling target 0.

  In the cooling device according to the second embodiment, the piping 5 may be arranged in different systems for each predetermined number of the plurality of cooling units 4 (cooling plates 1). It is practical to align the number of 4 (cooling plate 1) and the number of rows and columns. This example will be described using the case where one system shown in FIGS. 12 and 13 has nine cooling units 4 (cooling plates 1) in the row direction and three in the column direction. As can be seen from FIGS. 12 and 13, the refrigerant flow directions in adjacent systems are different, so the refrigerant temperature distribution in the simulated large cooling plate is low on the inlet side and high on the outlet side. This is offset to some extent between adjacent systems, so that a uniform or nearly uniform cooling function can be obtained as a whole.

  In the arrangement shown in FIG. 13, the flow direction of the refrigerant between the adjacent systems is different only in the arrangement of the cooling units 4 in the column direction, but the flow direction of the refrigerant between the adjacent systems is different in the row direction. This is not the case with the arrangement of the cooling units 4 alone, so the pipes on the refrigerant inflow side of the system 1 and the refrigerant outflow side of the system 3 in FIG. It is necessary to make the flow direction of the refrigerant between the systems different. Similarly, by using pipes bent in the same direction (side) on the refrigerant outflow side of system 2 and the refrigerant inflow side of system 4 in FIG. There is a need to.

  Overall, obtaining a uniform or nearly uniform cooling function increases as the number of systems increases. Therefore, the number of systems may be determined in a trade-off with the complexity of the structure. In FIG. 12 and FIG. 13, the number of systems of the pipe 5 is four, but the present invention is not limited to this. Moreover, all the piping 5 of each system | strain may be connected to the same pump 6, and may be connected to the pump 6 different for every piping 5 of each system | strain.

  The cooling device according to Embodiment 2 is formed inside the cooling plate 1, the flow path 2 through which the refrigerant passes, and the cooling unit 4 including the flexible heat conductive member 3 s formed on one surface of the cooling plate 1, A plurality of cooling units 4 arranged in a matrix, and a support unit 9 that supports one of at least two cooling plates 1 with an inclination relative to the other, and a pipe 5 that connects the flow paths of the plurality of cooling units 4, It can be said that it was equipped with. In the case of a large cooling object 0 having a heat dissipation surface exceeding the absorption allowance of the gap between the cooling part 4 and the cooling object 0 by the heat conducting member 3s, or one large cooling part for the large cooling object 0 This can be said to be suitable when it is difficult to create 4.

  In FIGS. 14 to 18, the ball portion of the ball joint disposed on the cooling portion 4 side is illustrated, but the ball portion of the ball joint may be disposed on the support portion 9 side. When the ball portion of the ball joint is arranged on the support portion 9 side, the predetermined range for changing the support angle of the cooling portion 4 can be expanded by the length of the suspension 12. In addition, when the ball portion of the ball joint is disposed on the cooling unit 4 side, a predetermined range for changing the support angle of the cooling unit 4 is narrowed, but a plurality of cooling units 4 can be arranged in a dense matrix. . Since the cooling unit 4 is movable, a large cooling plate is simulated by connecting the cooling plates 1 (cooling units 4) with flexible pipes 5 respectively.

Since 4 moves appropriately in the height direction, all the cooling plates 1 can automatically come into contact with the heat radiating surface by only the operation of pushing up the support portion 9 and can be cooled. Moreover, it can respond to a more complicated shape by making the cooling plate 1 small and increasing the number.
