  For example, a heat conductive sheet (heat dissipating part) may be installed in a narrow gap. In this case, the operator inserts a heat conductive sheet into the gap. However, if the heat conductive sheet is too soft, the heat conductive sheet is easily deformed. In this case, for example, the heat conductive sheet is easily deformed only by coming into contact with members around the gap. Further, the heat conductive sheet is easily deformed by the action of gravity. Therefore, when the operator inserts the heat conductive sheet into the gap, it may be difficult to insert the heat conductive sheet into the gap due to deformation of the heat conductive sheet.

  An object of this invention is to provide the heat radiating member which can install a heat radiating part in a clearance gap easily, and the apparatus with a heat radiating member.

It is an end view of the modification of an apparatus with a heat radiating member.

  Embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof is not repeated.

  With reference to FIG. 1, the apparatus 1 with a thermal radiation member which concerns on embodiment of this invention is demonstrated. FIG. 1 is a perspective view of a device 1 with a heat dissipation member. Below, the apparatus 1 with a heat radiating member may be described as the apparatus 1.

  As shown in FIG. 1, the device 1 of the present embodiment is a camera. The camera captures an image. The camera may be a surveillance camera. The camera may be, for example, a camera that uses visible light, an IR camera, or a thermal camera.

  The device 1 is not limited to a camera. The device 1 may be a device having a component that generates heat. The device 1 may be an electronic device such as a multifunction device, a smartphone, a PC (Personal Computer), a microwave oven, a refrigerator, and a rice cooker.

  The device 1 includes a heat dissipation member 100. The heat dissipating member 100 dissipates heat generated in the component of the device 1 to the outside of the component. In the present embodiment, the heat radiating member 100 is installed inside the device 1.

  Next, the heat radiating member 100 will be described with reference to FIGS. 2 to 3B. FIG. 2 is a perspective view of the heat dissipation member 100.

  As shown in FIG. 2, the heat radiating member 100 includes a heat radiating portion 110 and a sandwiching portion 120.

  FIG. 3A is a perspective view of the heat radiating part 110.

  As shown in FIGS. 2 and 3A, the heat radiating portion 110 has thermal conductivity. The heat radiation part 110 is formed in a sheet shape. The heat radiating part 110 is an insulating high heat conductive sheet made of an insulating resin material having a high thermal conductivity, for example. The resin material constituting the heat radiation unit 110 is, for example, a silicone resin or an acrylic resin. The heat radiating part 110 has a predetermined flexibility in order to make it easy to adhere to various shaped parts, for example.

  Moreover, the heat radiating part 110 may be elastically deformable. In this case, examples of the material constituting the heat radiating unit 110 include: Elastomer is included.

  In addition, the structure of the thermal radiation part 110 is not limited to the thing of this embodiment. The heat radiating unit 110 may be made of a material that radiates heat using the action of evaporation heat, such as a cooling gel sheet.

  FIG. 3B is a perspective view of the clamping unit 120.

  As shown in FIG. 2 and FIG. 3B, the holding unit 120 has a structure that can hold the heat radiating unit 110. The sandwiching portion 120 has, for example, a shape in which a flat plate-like member is bent in a substantially V shape. Bending includes the meaning of both bending and bending to bend. The clamping part 120 has a thickness of 0.05 mm or more and 0.5 mm or less, for example. As a result, it is possible to ensure the strength of the clamping unit 120 while ensuring the flexibility of the clamping unit 120.

  The clamping part 120 has thermal conductivity. The clamping part 120 is comprised with the material which has flexibility and heat conductivity. When the sandwiching portion 120 is made of metal, SUS or aluminum having high thermal conductivity is suitably used as the material constituting the sandwiching portion 120, for example, if it is inexpensive. In addition, the clamping part 120 may be comprised with the material which has flexibility and heat conductivity other than a metal. In this case, the clamping unit 120 is made of, for example, a carbon-based material.

  The rigidity of the clamping part 120 is higher than the rigidity of the heat dissipation part 110. Therefore, the clamping unit 120 is less likely to be deformed when receiving an external force than the heat dissipation unit 110.

  In addition, since the rigidity of the sandwiching portion 120 is higher than the rigidity of the heat radiating portion 110, the sandwiching portion 120 can support the heat radiating portion 110 by sandwiching the heat radiating portion 110. In other words, the flexibility of the heat radiating part 110 can be reinforced by the sandwiching part 120. As a result, the heat radiation part 110 can be easily installed in the gap 5 (see FIG. 6A).

  The clamping part 120 is elastically deformable. In the present embodiment, the clamping unit 120 functions as a leaf spring.

  The sandwiching unit 120 includes a first facing part 121 and a second facing part 122.

  The first facing portion 121 has a flat plate shape. The 1st opposing part 121 has the 1st opposing surface 121a and the 1st back surface 121b. The 1st back surface 121b shows the surface located in the back side of the 1st opposing surface 121a among the 1st opposing parts 121. As shown in FIG.

  The second facing portion 122 has a flat plate shape. The 2nd opposing part 122 has the 2nd opposing surface 122a and the 2nd back surface 122b. The 2nd back surface 122b shows the surface located in the back side of the 2nd counter surface 122a among the 2nd counter parts 122. As shown in FIG.

  The heat dissipating part 110 has a structure inserted in a space sandwiched between portions bent in a V shape of the sandwiching part 120. The heat radiating part 110 is installed between the first facing part 121 and the second facing part 122. Specifically, the heat radiating unit 110 is installed between the first facing surface 121 a of the first facing portion 121 and the second facing surface 122 a of the second facing portion 122.

  The heat radiating portion 110 faces the first facing surface 121a. Moreover, the heat radiating part 110 faces the second facing surface 122a.

  Next, the heat radiating member 100 will be further described with reference to FIG. FIG. 4 is a first end view of the heat radiating member 100 when an external force is not acting on the heat radiating member 100.

  The state where the external force is not acting on the heat radiating member 100 indicates a state where no external force is acting on each of the heat radiating part 110 and the sandwiching part 120.

  As shown in FIG. 4, the first facing portion 121 has a first distal end portion 12a and a first proximal end portion 12b. The 2nd opposing part 122 has the 2nd front-end | tip part 12c and the 2nd base end part 12d.

  The clamping unit 120 further includes a fulcrum part 123. The fulcrum part 123 is interposed between the first base end part 12b and the second base end part 12d.

  The first facing part 121 and the second facing part 122 are connected via a fulcrum part 123.

  The first tip portion 12a and the second tip portion 12c protrude from the fulcrum portion 123 in different directions.

  FIG. 4 shows the tilt angle Q. The tilt angle Q indicates the tilt angle of the second facing portion 122 with respect to the first facing portion 121.

  When the external force is not acting on the heat radiating member 100, the inclination angle Q becomes the predetermined angle Q1. The predetermined angle Q1 is, for example, an angle of 40 ° or more and an angle of 80 ° or less. The predetermined angle Q1 is preferably an angle of 60 °.

  When an external force is not applied to the heat radiating member 100, the interval V between the first tip portion 12a and the second tip portion 12c is a predetermined interval V1 (V1> 0).

  The first tip portion 12a and the second tip portion 12c are supported so as to be close to and away from each other. The first tip portion 12a and the second tip portion 12c are close to or separated from each other around the fulcrum portion 123.

  When the first tip portion 12a and the second tip portion 12c are close to each other, the inclination angle Q becomes small. On the other hand, when the first tip portion 12a and the second tip portion 12c are separated from each other, the inclination angle Q becomes small.

  FIG. 4 further shows a proximity direction A and a separation direction B. The approach direction A indicates a direction in which the first tip portion 12a and the second tip portion 12c are close to each other. The separation direction B indicates a direction in which the first tip portion 12a and the second tip portion 12c are separated from each other.

  When the interval V between the first tip portion 12a and the second tip portion 12c is smaller than the predetermined interval V1, the clamping unit 120 generates a first restoring force in order to return the interval V to the predetermined interval V1. The first restoring force is generated in a direction in which the first tip portion 12a and the second tip portion 12c are moved in the separation direction B. In other words, the first restoring force is generated in the direction of increasing the inclination angle Q.

  The first restoring force is an example of the restoring force of the present invention.

  When the interval V between the first tip portion 12a and the second tip portion 12c becomes larger than the predetermined interval V1, the clamping unit 120 generates a second restoring force in order to return the interval V to the predetermined interval V1. The second restoring force is generated in a direction in which the first tip portion 12a and the second tip portion 12c are moved in the proximity direction A. In other words, the second restoring force is generated in the direction of decreasing the inclination angle Q.

  The device 1 will be described with reference to FIGS. 5 to 6B. FIG. 5 is an end view of the device 1.

  As shown in FIG. 5, the device 1 further includes a first component 2, a second component 3, and a base 4.

  The first component 2 is a component that generates heat. The component is, for example, an electronic component that generates heat when a current flows, such as an image sensor, a control circuit, or an IC chip. The first component 2 is a component to be radiated by the heat radiating member 100.

  The second component 3 is, for example, a housing that houses the first component 2 or a metal connector. The second component 3 may be a component that generates heat. The second component 3 may not be a component that generates heat. That is, at least one of the first component 2 and the second component 3 may be a component that generates heat. In the present embodiment, the first component 2 is a component that generates heat, and the second component 3 is a component that does not generate heat. In this case, heat dissipation grease may be applied to the first back surface 121b of the first facing portion 121. That is, the heat radiating member 100 further includes heat radiating grease, and the heat radiating grease is disposed between the sandwiching portion 120 and the heat radiating portion 110. As a result, the heat generated in the first component 2 can be effectively radiated to the outside of the first component 2.

  The first component 2 and the second component 3 are installed on the base 4.

  The first component 2 and the second component 3 are arranged along the width direction C so as to be spaced from each other.

  The heat dissipation member 100 is installed between the first component 2 and the second component 3. When the heat radiating member 100 is installed between the first component 2 and the second component 3, the first facing portion 121 and the second facing portion 122 sandwich the heat radiating portion 110. The first facing portion 121 and the second facing portion 122 sandwich the heat radiating portion 110 from both sides in the width direction C.

  When the first facing portion 121 and the second facing portion 122 sandwich the heat radiating portion 110, the first facing surface 121a (see FIG. 3B) and the second facing surface 122a are in contact with the heat radiating portion 110. .

  Further, the heat dissipating member 100 is disposed between the first component 2 and the second component 3 such that the first back surface 121b faces the first component 2 and the second back surface 122b faces the second component 3. Installed between.

  When the heat dissipation member 100 is installed between the first component 2 and the second component 3, the first back surface 121 b contacts the first component 2, and the second back surface 122 b is the second component 3. To touch.

  The heat generated in the first component 2 is conducted to the heat radiating part 110 through the sandwiching part 120. As a result, the heat radiating unit 110 radiates the heat generated in the first component 2 to the outside of the first component 2.

  Next, with reference to FIG. 5 to FIG. 6B, dimensions of various parts constituting the device 1 will be described.

  FIG. 5 shows the thickness dimension X1. The thickness dimension X <b> 1 indicates the thickness dimension of the heat dissipation part 110 when the heat dissipation member 100 is installed between the first component 2 and the second component 3.

  FIG. 6A is an end view showing the first component 2 and the second component 3.

  As shown in FIG. 6A, a gap 5 is located between the first component 2 and the second component 3. A heat radiating member 100 is installed in the gap 5 (see FIG. 5).

  FIG. 6A shows the width dimension W. FIG. The width dimension W is a dimension in the width direction C of the gap 5.

  FIG. 6B is a second end view of the heat radiating member 100 when an external force is not acting on the heat radiating member 100.

  FIG. 6B shows the thickness dimension X2 of the heat radiating part 110, the thickness dimension Y1 of the first facing part 121, and the thickness dimension Y2 of the second facing part 122.

  The thickness dimension X <b> 2 indicates the thickness dimension of the heat radiating part 110 when the external force is not acting on the heat radiating member 100.

  The thickness dimension Y <b> 1 indicates the thickness dimension of the first facing portion 121 when the external force is not acting on the heat radiating member 100.

  The thickness dimension Y <b> 2 indicates the thickness dimension of the second facing portion 122 when the external force is not acting on the heat radiating member 100.

  Hereinafter, the sum of the thickness dimension X2, the thickness dimension Y1, and the thickness dimension Y2 is referred to as a first member dimension Z1 (X2 + Y1 + Y2 = Z1). Moreover, the sum of thickness dimension Y1 and thickness dimension Y2 is described as 2nd member dimension Z2 (Y1 + Y2 = Z2).

  The first member dimension Z1 is an example of the member dimension of the present invention.

  With reference to FIG. 6A and FIG. 6B, the relationship among the first member dimension Z1, the second member dimension Z2, and the width dimension W will be described.

  As shown in FIGS. 6A and 6B, the first member dimension Z1 is larger than the width dimension W (W <Z1). The second member dimension Z2 is smaller than the width dimension W (Z2 <W).

  With reference to FIG.5 and FIG.6 (b), the relationship between the thickness dimension X1 and the thickness dimension X2 is demonstrated.

  As shown in FIGS. 5 and 6B, the thickness dimension X1 is smaller than the thickness dimension X2 (X1 <X2).

  The principle that the thickness dimension X1 becomes smaller than the thickness dimension X2 will be described.

  As described above, the first member dimension Z1 is larger than the width dimension W (Z1> W). Therefore, in this state, the heat radiating member 100 cannot be installed in the gap 5. Therefore, when the heat radiating member 100 is installed in the gap 5, the heat radiating part 110 is deformed so that the thickness of the heat radiating part 110 is reduced. At this time, the thickness of the heat radiating part 110 is reduced to the extent that the difference (Z1−W) between the first member dimension Z1 and the width dimension W is eliminated. The reason is that the heat radiating member 100 can be installed in the gap 5 by eliminating the difference (Z1−W) between the first member dimension Z1 and the width dimension W. As a result, the thickness dimension X1 becomes smaller than the thickness dimension X2.

  In addition, that the thickness of the heat radiating part 110 becomes thin means that the thickness dimension of the heat radiating part 110 is smaller than the thickness dimension X2.

  Further, when the heat radiating member 100 is installed in the gap 5, the heat radiating portion 110 is sandwiched between the first facing portion 121 and the second facing portion 122. The heat radiating unit 110 receives a clamping pressure in the proximity direction A from the first opposed unit 121 and the second opposed unit 122. And the heat radiation part 110 deform | transforms so that the thickness of the heat radiation part 110 may become thin with clamping pressure.

  As described above with reference to FIGS. 5 and 6B, the first member dimension Z1 is larger than the width dimension W. Therefore, when the heat radiating member 100 is installed in the gap 5, the heat radiating portion 110 can be brought into close contact with the first facing portion 121. As a result, since it is possible to suppress the generation of an air layer between the first facing portion 121 and the heat radiating portion 110, the heat generated in the first component 2 can be effectively radiated to the outside of the first component 2. it can.

  Further, when the heat dissipating member 100 is installed in the gap 5, the interval between the first tip portion 12a and the second tip portion 12c becomes smaller than the predetermined interval V1 (see FIG. 4). When the interval between the first tip portion 12a and the second tip portion 12c is smaller than the predetermined interval V1, a first restoring force is generated in the separation direction B with respect to the first tip portion 12a and the second tip portion 12c. Accordingly, the first facing portion 121 can be brought into close contact with the first component 2 by the first restoring force. As a result, it is possible to suppress the generation of an air layer between the first component 2 and the first facing portion 121, so that the heat generated in the first component 2 can be effectively dissipated to the outside of the first component 2. Can do.

  When the heat dissipating member 100 is installed in the gap 5 (see FIG. 5), the thickness dimension of the first facing portion 121 is maintained at the thickness dimension Y1 (see FIG. 6B), and further the second facing portion. The thickness dimension of 122 is held at the thickness dimension Y2. The reason is that the rigidity of the sandwiching portion 120 is higher than the rigidity of the heat radiating portion 110, and the sandwiching portion 120 is less likely to deform than the heat radiating portion 110.

  Next, a procedure for installing the heat dissipation member 100 in the gap 5 will be described with reference to FIGS. FIG. 7 is a first diagram illustrating the installation procedure of the heat dissipation member 100.

  As shown in FIG. 7, first, proximity pressure is applied to the first facing portion 121 and the second facing portion 122. The proximity pressure is applied in the proximity direction A to the first facing portion 121 and the second facing portion 122. The proximity pressure is applied, for example, by sandwiching the first back surface 121b of the first facing portion 121 and the second back surface 122b of the second facing portion 122 with a tool α such as pliers.

  FIG. 8 is a second diagram illustrating the installation procedure of the heat dissipation member 100.

  As shown in FIG. 8, when the proximity pressure is applied to the first facing portion 121 and the second facing portion 122, the posture of the heat dissipation member 100 becomes the clamping posture G. The sandwiching posture G indicates the posture of the heat radiating member 100 when the heat radiating portion 110 is sandwiched between the first facing portion 121 and the second facing portion 122. Then, the heat radiating member 100 is inserted into the gap 5 in a state where the heat radiating member 100 is in the clamping posture G. As a result, the heat radiating member 100 is installed in the gap 5 as shown in FIG.

  As described above with reference to FIGS. 5, 7, and 8, when the heat radiating member 100 is installed in the gap 5, the heat radiating portion 110 is sandwiched between the first facing portion 121 and the second facing portion 122. In this state, it is inserted into the gap 5. Therefore, deformation of the heat radiating part 110 is suppressed. As a result, the heat radiating part 110 can be easily installed in the gap 5.

  In addition, the heat dissipation member 100 has a structure in which the sandwiching portion 120 is bent. Therefore, the heat dissipation member 100 has a shape in which the distal end portion in the insertion direction is tapered while being bent. As a result, the heat dissipation member 100 can be formed into a shape that can be easily inserted into the gap 5. In addition, the front-end | tip part of the insertion direction among the thermal radiation members 100 shows the fulcrum part 123 (refer FIG. 5) which is the bent part among the clamping parts 120. FIG.

  Moreover, the clamping part 120 has flexibility. Therefore, when the heat dissipating member 100 is inserted into the gap 5, the restoring force of the sandwiching portion 120 is generated in the width direction C (see FIG. 5). As a result, the clamping part 120 presses each of the first component 2 and the second component 3 with a restoring force, so that the heat dissipation member 100 can be fixed in the gap 5.

  With reference to FIG. 9, the modification of the apparatus 1 with a heat radiating member is demonstrated. FIG. 9 is an end view of a modification of the device 1 with a heat radiating member.

  As shown in FIG. 9, a plurality of heat dissipation members 100 are inserted into the gap 5. The plurality of heat dissipation members 100 are arranged along the width direction C (see FIG. 5). Therefore, by adjusting the number of the heat dissipating members 100 inserted into the gap 5 according to the width of the gap 5 in the width direction C, the heat dissipating member 100 is installed in the gap 5 so as to eliminate the gap 5 in the width direction C. It becomes possible. As a result, the heat dissipation member 100 can be effectively fixed in the gap 5. In FIG. 9, two heat radiating members 100 are inserted into the gap 5. However, three or more heat dissipation members 100 may be inserted into the gap 5.

  The embodiment of the present invention has been described above with reference to the drawings (FIGS. 1 to 9). However, the present invention is not limited to the above-described embodiment, and can be implemented in various modes without departing from the gist thereof. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the above embodiments. For example, some components may be deleted from all the components shown in the embodiment.
