Problems to be Solved by the Invention

[0004] While the inventor was developing a heat exchange panel that can be used for cooling the battery of an electric vehicle, it was found that in the configuration of Patent Document 1, when the pipe is made of metal, the weight of the panel tends to be excessive, and when the pipe is made of resin, the heat exchange efficiency tends to be insufficient.

Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described. Various features shown in the following embodiments can be combined with each other. Further, an invention can be achieved independently for each feature. Furthermore, among the following embodiments, elements not defined in the claims are arbitrary elements and can be omitted.

[0010] 1. Heat exchange panel 1 With reference to FIGS. 1 to 3, a heat exchange panel 1 according to an embodiment of the present invention will be described. The heat exchange panel 1 includes a base material 2 and a metal plate 3, and a flow path 4 through which a heat medium flows is provided inside. The heat exchange panel 1 can be used for promoting heat exchange between the heat medium flowing through the flow path 4 and an object 31 (shown in FIG. 6) in contact with the metal plate 3. The heat medium can enter and exit the flow path 4 through a pair of open ends 1a, 1b (shown in FIG. 2C). The heat exchange may be heating or cooling of the object 31. That is, the heat exchange panel 1 may be a heating panel for heating the object 31 or a cooling panel for cooling the object 31. Further, it may be a temperature control panel for heating or cooling the object 31 to keep the temperature of the object 31 constant. The heat exchange panel 1 may be installed in a building like a floor heating panel or may be movable. Hereinafter, each component will be described in detail.

[0011] The base material 2 is made of a foam and includes a flow path 4 through which a heat medium can flow. Since the base material 2 is formed of a foam, heat conduction through the base material 2 is suppressed and heat exchange through the metal plate 3 is promoted. Such a base material 2 can be obtained by molding a molten resin sheet in a foamed state, as will be described later. The material of the base material 2 is a thermoplastic resin such as polyolefin, and examples of the polyolefin include low-density polyethylene, linear low-density polyethylene, high-density polyethylene, polypropylene, ethylene-propylene copolymer, and a mixture thereof. The heat medium is a medium used for transferring heat, and is, for example, water.

[0012] The expansion ratio of the foam constituting the base material 2 is, for example, 2 to 10 times, preferably 3 to 8 times. Specifically, this expansion ratio is, for example, 2, 3, 4, 5, 6, 7, 8, 9, 10 times, and may also be in the range between any two of the values exemplified herein. The thickness of the base material 2 is, for example, 2 to 20 mm, preferably 3 to 10 mm. Specifically, this thickness is, for example, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 mm, and may also be in the range between any two of the values exemplified herein.

[0013] In one example, the base material 2 is a square or rectangle with rounded corners in a plan view (that is, when viewed from a direction perpendicular to the surface of the metal plate 3, the same applies hereinafter). The length of the short side of this rectangle is, for example, 50 to 700 mm (110 mm in this embodiment), and specifically, for example, 50, 100, 150, 200, 300, 400, 500, 600, 700 mm, and may also be in the range between any two of the values exemplified herein. The value of [long side length / short side length] is, for example, 1 to 5 (2.7 in this embodiment), and specifically, for example, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, and may also be in the range between any two of the values exemplified herein. When the base material 2 is square, the two orthogonal sides are referred to as the short side and the long side for convenience.

[0014] The flow path 4 is constituted by a recess 2b provided on the base surface 2a of the base material 2. The base surface 2a can be of any shape to which the metal plate 3 can be adhered. The base surface 2a is preferably a flat surface, but may be, for example, a shape that covers the object 31 to be heat-exchanged. The flow path 4 can be configured in any shape through which a heat medium can circulate (in other words, can communicate with a pair of open ends 1a, 1b). The flow path 4 is preferably groove-shaped, but may be, for example, a recessed shape like a tray. Preferably, the flow path 4 extends along the longitudinal direction or the short-side direction of the base material 2 and is configured to fold back near the ends. The flow path 4 preferably includes a flow path main body 4a and a deep recess 4b. The deep recess 4b is a portion that communicates with the flow path main body 4a and has a deeper recess depth than the flow path main body 4a. The deep recess 4b is preferably circular in plan view. The deep recess 4b is preferably provided at the end of the flow path main body 4a, and preferably provided at each of both ends.

[0015] The ratio of the projected area of the flow path 4 to the projected area of the metal plate 3 (the area in plan view; the same shall apply hereinafter) is, for example, 0.1 to 0.9 (0.34 in this embodiment), and preferably 0.2 to 0.6. If this ratio is too small, the heat exchange efficiency may become too low, and if this ratio is too large, the adhesive strength between the base surface 2a and the metal plate 3 may become too low. Specifically, this ratio is, for example, 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, 0.40, 0.45, 0.50, 0.55, 0.60, 0.65, 0.70, 0.75, 0.80, 0.85, 0.90, and may be in the range between any two of the numerical values exemplified herein.

[0016] As shown in Fig. 3, when the width of the flow path body 4a is W and the depth is Dp, W / Dp is, for example, 1.1 to 5.0, preferably 1.5 to 4.0. Specifically, this value is, for example, 1.1, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, and may be in the range between any two of the values exemplified herein. The larger this value is, the easier it is to make the base material 2 thinner. When the depth of the deep recess 4b is Dp1 and the thickness of the base material is T, Dp / T and Dp1 / T are, for example, 0.1 to 0.9 (in this embodiment, Dp / T is 0.5 and Dp1 / T is 0.8). Dp / T is preferably 0.3 to 0.7, and Dp1 / T is preferably 0.5 to 0.9. Specifically, Dp / T and Dp1 / T are, for example, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, and may be in the range between any two of the values exemplified herein. Dp1 / T is larger than Dp / T.

[0017] As shown in Fig. 2A, when the distance between two adjacent flow path bodies 4a (the length in the direction perpendicular to the longitudinal direction of the flow path body 4a) is G, G / W is, for example, 0.5 to 3.0 (in this embodiment, it is 1.25), preferably 0.8 to 2.0. If this value is too small, the adhesion strength between the base surface 2a and the metal plate 3 may become too low. If this value is too large, the heat exchange efficiency may become too low. Specifically, this value is, for example, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, and may be in the range between any two of the values exemplified herein.

[0018] When the diameter of the deep recess 4b at the opening edge is D, D / W is, for example, 1.5 to 6.0 (in this embodiment, it is 3.4), preferably 2.0 to 5.0. Specifically, this value is, for example, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, and may be in the range between any two of the values exemplified herein.

[0019] The metal plate 3 is adhered to the base surface 2a. In one example, after forming the base material 2, the metal plate 3 can be adhered to the base surface 2a using an adhesive. The metal plate 3 is preferably adhered to the base surface 2a in the region surrounding the flow path 4 so that the heat medium in the flow path 4 does not leak from the gap between the metal plate 3 and the base material 2, and it is preferably adhered to the entire base surface 2a. The thickness of the metal plate 3 is, for example, 0.1 to 1.5 mm (in this embodiment, 0.5 mm), and 0.3 to 1.0 mm is preferable. Specifically, this value is, for example, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5 mm, and it may be in the range between any two of the values exemplified here. Examples of the material of the metal plate 3 include aluminum, iron, SUS, etc., and aluminum is preferable from the viewpoint of weight reduction. The value of [area of metal plate 3 / area of base material 2] is, for example, 0.6 to 1.0 (in this embodiment, 1.0), and specifically, for example, 0.6, 0.7, 0.8, 0.9, 1.0, and it may be in the range between any two of the values exemplified here. The area of the metal plate 3 and the area of the base material 2 each mean the area of the region surrounded by the outer periphery of the metal plate 3 and the base material 2 in plan view.

[0020] It is preferable that the base material 2 is provided with a pair of through holes 5 that penetrate the base material 2 and communicate with the flow path 4. The through holes 5 serve as the inlet and outlet of the heat medium to the flow path 4. In this case, the degree of freedom in the design of the flow path 4 is increased compared to the case where the open end of the flow path 4 is provided on the side surface of the heat exchange panel 1. The through holes 5 are preferably provided so as to penetrate the bottom wall 4b1 of the deep recess 4b.

[0021] As shown in FIGS. 2 to 3, a connection unit 6 is attached to each through hole 5. The connection unit 6 includes an inner member 7 and an outer member 8. As shown in FIG. 3, the inner member 7 includes an inner base 7a and an inner protruding cylinder 7b protruding from the inner base 7a. The inner member 7 is provided with an inner through hole 7c penetrating the inner base 7a and the inner protruding cylinder 7b. The outer member 8 includes an outer base 8a and an outer protruding cylinder 8b protruding from the outer base 8a. The outer member 8 is provided with an outer through hole 8c penetrating the outer base 8a and the outer protruding cylinder 8b. As shown in FIGS. 2D and 3, the inner base 7a and the outer base 8a are arranged to face each other with the base material 2 interposed therebetween. More specifically, the inner base 7a is arranged in the deep recess 4b, and the inner base 7a and the outer base 8a are arranged to face each other with the bottom wall 4b1 of the deep recess 4b interposed therebetween. The inner protruding cylinder 7b is inserted into the outer through hole 8c through the through hole 5.

[0022] Leakage of the heat medium from the flow path 4 is suppressed by the outer peripheral surface of the inner protruding cylinder 7b and the inner peripheral surface of the outer through hole 8c being in close contact at the contact portion 9. The outer peripheral surface of the inner protruding cylinder 7b and the inner peripheral surface of the outer through hole 8c may be in close contact over the entire opposing portions, but in that case, the resistance when inserting the inner protruding cylinder 7b into the outer through hole 8c may become too large. Therefore, it is preferable that the outer peripheral surface of the inner protruding cylinder 7b and the inner peripheral surface of the outer through hole 8c are in close contact at the contact portion 9 and not in close contact at the other portions 9a. The ratio of the contact portion 9 to the total length of the outer through hole 8c is, for example, 0.05 to 0.30 (0.17 in this embodiment), and preferably 0.10 to 0.25. Specifically, this ratio is, for example, 0.05, 0.10, 0.15, 0.20, 0.25, 0.30, and may be in the range between any two of the numerical values exemplified here. The contact portion 9 is preferably provided at a portion of the outer through hole 8c corresponding to the outer base 8a. By making the diameter of the outer through hole 8c formed in the outer base 8a slightly smaller than the diameter of the outer through hole 8c formed in the outer protruding cylinder 8b, the contact portion 9 can be provided at the portion corresponding to the outer base 8a.

[0023] The inner base 7a preferably adheres closely to the bottom surface of the deep recess 4b. By doing so, leakage of the heat medium from the gap between the inner base 7a and the base material 2 is suppressed. Regarding the upper surface of the inner base 7a (the surface facing the metal plate 3), it is preferable that the distance L from the base surface 2a is greater than the depth Dp of the flow path body 4a. In this case, the inner base 7a is suppressed from blocking the flow path body 4a.

[0024] It is preferable that one or both of the inner member 7 and the outer member 8 are made of an elastomer. In this case, the adhesion between the inner member 7 and the outer member 8 can be enhanced. Considering the point of making the inner base 7a adhere closely to the bottom surface of the deep recess 4b, it is preferable that at least the inner member 7 is made of an elastomer. Also, it is preferable that one or both of the inner member 7 and the outer member 8 are joined (such as adhered or welded) to the base material 2, and it is more preferable that they are welded. In this case, leakage of the heat medium can be further suppressed.

[0025] In this embodiment, the connection unit 6 mounted on the through hole 5 constitutes the open ends 1a, 1b, and the heat medium is transferred to the flow path 4 through the inner through hole 7c.

[0026] Let the cross-sectional area of a cross-section perpendicular to the longitudinal direction of the inner through hole 7c be S1, and the cross-sectional area of a cross-section perpendicular to the longitudinal direction of the flow path body 4a be S2. Then, S2 / S1 is 0.5 to 10 (3.3 in this embodiment), and preferably 1 to 6. If this value is too large or too small, the narrow cross-sectional area part becomes a bottleneck and the flow rate of the heat medium decreases, and the temperature difference of the heat medium near the entrance and the exit of the flow path body 4a may become too large. Specifically, this value is, for example, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 6.0, 7.0, 8.0, 9.0, 10, and it may also be in the range between any two of the numerical values exemplified here.

[0027] 2. Manufacturing method of the heat exchange panel 1 The heat exchange panel 1 can be manufactured by adhering a metal plate 3 to the base surface 2a of the base material 2. When attaching the connection unit 6 to the base material 2, the metal plate 3 can be adhered to the base surface 2a after attaching the connection unit 6 to the base material 2.

[0028] 3. Foaming molding machine 10 The base material 2 can be manufactured using, for example, the foaming molding machine 10 shown in FIG. 4. The foaming molding machine 10 includes a resin supply device 20, a T-die 18, and molds 21, 22. The resin supply device 20 includes a hopper 12, an extruder 13, and an injector 16.

[0029] Hereinafter, each component will be described in detail.

[0030] <Hopper 12, extruder 13> The hopper 12 is used to feed the raw material resin 11 into the cylinder 13a of the extruder 13. The form of the raw material resin 11 is not particularly limited, but is usually in pellet form. After the raw material resin 11 is fed from the hopper 12 into the cylinder 13a, it is melted by being heated in the cylinder 13a to become a molten resin. Further, it is conveyed toward the tip of the cylinder 13a by the rotation of the screw disposed in the cylinder 13a.

[0031] <Injector 16> An injector 16 for injecting a foaming agent into the cylinder 13a is provided in the cylinder 13a. The foaming agent injected from the injector 16 is preferably a supercritical fluid of carbon dioxide or nitrogen.

[0032] <Accumulator 17, T-die 18> The foaming agent-containing resin 11a obtained by melt-kneading a raw material resin and a foaming agent is extruded from the resin extrusion port of the cylinder 13a and injected into the T-die 18. The T-die 18 incorporates an accumulator 17. After storing a predetermined amount of the foaming agent-containing resin 11a in the T-die 18, the piston 17a of the accumulator 17 is moved toward the slit 18a, whereby the foaming agent-containing resin 11a is extruded from the slit 18a and dropped to form the foamed resin sheet 23. Note that the accumulator 17 may be separate from the T-die 18.

[0033] <The first and second molds 21, 22> The foamed resin sheet 23 is guided between the first and second molds 21, 22 configured to be openable and closable. The first and second molds 21, 22 each include cavity surfaces 21a, 22a. When the cavity surfaces 21a, 22a are combined, a cavity 33 (shown in FIG. 5) corresponding to the outer surface shape of the base material 2 is formed. A number of vacuum suction holes (not shown) are provided in the cavity surfaces 21a, 22a, respectively, and it is possible to vacuum-suction the foamed resin sheet 23 to shape it along the cavity surfaces 21a, 22a.

[0034] 4. Manufacturing method of the base material 2 With reference to FIGS. 4 to 5, the manufacturing method of the base material 2 according to an embodiment of the present invention will be described. The method of this embodiment includes an arrangement step and a molding step. Details will be described below.

[0035] 4.1 Arrangement step In this step, as shown in FIG. 4, a foamed resin sheet 23 formed by extruding and suspending a foaming agent-containing resin 11a in a molten state from a slit 18a of a T-die 18 is placed between molds 21 and 22 in an open state. In this embodiment, since direct vacuum forming is performed using the foamed resin sheet 23 extruded from the T-die 18 as it is, the foamed resin sheet 23 is not cooled to room temperature and solidified before forming, and the solidified foamed resin sheet 23 is not heated before forming. The thickness of the foamed resin sheet 23 is not particularly limited, but for example, it is 0.5 to 5 mm, preferably 1 to 3 mm. Specifically, this thickness is, for example, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5 mm, and it may be within the range between any two of the numerical values exemplified here.

[0036] 4.2 Forming Step In this step, as shown in FIG. 5, the molds 21 and 22 are closed to form the foamed resin sheet 23.

[0037] When the molds 21 and 22 are closed, the volume of the foamed resin sheet 23 accommodated in the cavity 33 may be larger or smaller than the volume of the cavity 33. When the volume of the foamed resin sheet 23 is larger than the volume of the cavity 33, the foamed resin sheet 23 is compressed by the molds 21 and 22 to form the base material 2.

[0038] On the other hand, when the volume of the foamed resin sheet 23 is smaller than the volume of the cavity, the foamed resin sheet 23 is attracted by the vacuum suction holes provided on the cavity surfaces 21a and 22a of the molds 21 and 22, and the foamed resin sheet 23 is shaped along the cavity surfaces 21a and 22a while expanding the foamed resin sheet 23, thereby forming the base material 2. In this case, there is an advantage that the foaming ratio of the base material 2 can be increased. Further, when the foamed resin sheet 23 is attracted by the vacuum suction holes, the bubbles near the surface of the foamed resin sheet 23 are crushed, so a skin layer with a relatively small average bubble diameter is formed on the surface of the base material 2. Since the skin layer is excellent in strength and smoothness, the strength and smoothness of the base material 2 are enhanced by the formation of the skin layer.

[0039] Through this step, as shown in FIG. 5, a foam molded body 34 having a structure in which burrs 23a are attached to the base material 2 is obtained. By removing the burrs 23a from the foam molded body 34, the base material 2 can be obtained. The removal of the burrs 23a may be performed before the foam molded body 34 is taken out of the molds 21 and 22, or may be performed after the foam molded body 34 is taken out of the molds 21 and 22.

[0040] 5. Heat exchange system 30 As shown in FIG. 6, a heat exchange system 30 according to an embodiment of the present invention includes a heat exchange panel 1, an object 31, and a circulation device 32. The object 31 is arranged to contact the metal plate 3. The circulation device 32 is configured to circulate the heat medium while adjusting the temperature of the heat medium flowing through the flow path 4. When the heat exchange system 30 is a cooling system, the circulation device 32 cools the heat medium, and when the heat exchange system 30 is a heating system, the circulation device 32 heats the heat medium.

[0041] In one example, the circulation device 32 includes pipes 32a and 32b, a pump 32c, and a temperature regulator 32d. The pipes 32a and 32b are connected to a pair of open ends 1a and 1b that serve as inlets and outlets of the heat medium to the flow path 4. The pump 32c has a function of sending the heat medium downstream. The temperature regulator 32d has a function of adjusting (heating or cooling) the temperature of the heat medium. When the heat exchange system 30 is a cooling system, the temperature regulator 32d is configured to be able to cool the heat medium, such as a chiller or a radiator, and when the heat exchange system 30 is a heating system, the temperature regulator 32d is configured to be able to heat the heat medium, such as a heater. According to such a configuration, the heat medium can flow along the flow path 4 by the action of the pump 32c to cool or heat the object 31. As the object 31 is cooled or heated, the heat medium is heated or cooled. Then, after the heat medium is cooled or heated by the temperature regulator 32d, it is sent into the flow path 4 again. Therefore, according to the present embodiment, the object 31 can be continuously cooled or heated.

[0042] In one example, the heat exchange system 30 can be mounted on a vehicle such as an electric vehicle and used for cooling the battery. In this case, the circulation device 32 is configured to cool the heat medium. In a vehicle such as an electric vehicle, where the battery tends to become hot, the heat exchange system 30 of the present embodiment can suppress the temperature rise of the battery by cooling the battery.
