Description

Technical Field

[0001] The present invention relates to the technical field of ceramic heating devices, and in particular to a heating module. Background Art

[0002] In existing heating modules, the heating element and the heat conductor are generally connected by direct fixing or plugging. There is no thermal spring structure between the heating element and the heat conductor that can produce elastic deformation when subjected to force. In addition, due to errors in the production process of the heating element and the heat conductor, resulting in dimensional inconsistency, it is easy to encounter installation difficulties when the heating element and the heat conductor are directly assembled later. At the same time, the ceramic heating module used in the existing heating device is relatively brittle and easy to break, and may be deformed by heat. If the heating element and the heat conductor are directly assembled and contacted, the heat conductor will be deformed by heat and cause the heating element to break. At the same time, direct contact between the heating element and the heat conductor during assembly or transportation may also cause the heating element or the heat conductor to break.

[0003] The existing heat conducting sheet structures for transferring heat are mostly single-piece structures, and the heat conducting sheet is not elastically designed. In addition, the existing heat conducting sheet structures are mostly assembled by bonding or extrusion. Due to the dimensional inconsistency caused by production errors of the heat conducting sheet, heating element and heat conductor, the existing heat conducting sheet cannot undergo elastic deformation during the installation process, resulting in poor contact, which in turn leads to the problem of large thermal resistance.

[0004] In response to the above needs, it is necessary to propose a heating module that can, under the premise of ensuring full contact with the heating element and the heat conductor, increase the contact area with the heating element and the heat conductor through the elastic deformation of the thermal spring, reduce the thermal resistance, increase the contact area with the air for full heat exchange, and flexibly increase the number of heating elements. Summary of the Invention

[0005] In order to solve at least one problem existing in the above-mentioned prior art, according to one aspect of the present invention, a heating module is provided, which increases the contact area with the air by the heat conductor to fully exchange heat. According to actual needs, an appropriate number of heating elements are selected and installed on the heat conductor. The heat-conducting spring is installed in the buffer zone between the heating block mounting hole and the heating element, which can better transfer the heat from the heating element to the heat conductor so that the contact area with the air can fully exchange heat. At the same time, the contact edge provided on the heat-conducting spring includes a first contact part, a second contact part and a transition part, so that during the assembly process of the heat-conducting spring, the second contact part is subjected to external force, and the first contact part is driven to move toward the outside of the contact edge through the transition part, so that the contact edge can produce elastic deformation, so that the heat-conducting spring can adapt to heating elements and heat conductors with different sizes due to processing problems.

[0006] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is as follows:

[0007] A heating module, comprising:

[0008] A heat conductor, wherein a plurality of mounting holes are provided on the heat conductor;

[0009] A heating element, wherein a plurality of heating elements are provided and the heating elements are placed in the mounting holes;

[0010] The thermally conductive spring comprises a bending edge and a contact edge, the contact edge is extended from the circumferential edge of the bending edge in a direction away from the bending edge, and an angle is formed between the contact edge and the bending edge. The contact edge comprises a first contact portion connected to the bending edge, a second contact portion away from the bending edge, and a transition portion connecting the first contact portion and the second contact portion. The extension surface of the first contact portion and the extension surface of the second contact portion are in different planes, and the contact edge can produce elastic deformation relative to the bending edge when subjected to force; the thermally conductive spring is installed between the mounting hole on the heat conductor and the heating element.

[0011] With this arrangement, the heat conductor can be used to increase the contact area with the air for sufficient heat exchange. The heating element can be movably installed on the heat conductor, and the thermal spring is installed in the buffer zone between the heating block mounting hole and the heating element, which can achieve better transfer of heat from the heating element to the heat conductor so that the contact area between the heat conductor and the air can be fully exchanged with heat. At the same time, the thermal spring can avoid the problem of poor contact caused by inconsistent sizes when the heat conductor and the heating element are directly assembled, thereby reducing thermal resistance and improving thermal conductivity. At the same time, the thermal spring can also prevent the unreasonable gap between the heat conductor and the heating element, causing the heating element to rupture during production or transportation, or the heat conductor to deform due to heat, causing the heating element to rupture.

[0012] Preferably, the contact edge of the thermally conductive spring is inserted into the mounting hole of the thermal conductor, and the contact edge of the thermally conductive spring is inserted between the thermal conductor and the heating element. The outer wall of the first contact portion contacts the inner wall of the mounting hole on the thermal conductor, and the bottom wall of the bent edge contacts the upper end surface of the thermal conductor. At the same time, the contact edge is sleeved on the heating element so that the inner side wall of the second contact portion contacts the outer side wall of the heating element, so that the thermally conductive spring transfers the heat of the heating element to the thermal conductor.

[0013] With this arrangement, after the bottom wall of the bent edge contacts the upper end face of the heat conductor, the bent edge overlaps the heat conductor, thereby ensuring that the heat-conducting spring can be firmly assembled in the mounting hole of the heat conductor, and the contact edge is inserted between the heat conductor and the heating element to ensure that the heat-conducting spring transfers the heat of the heating element to the heat conductor. Since the bent edge and the contact edge are not in the same plane, when the contact edge contacts the heating element during assembly, the heating element squeezes the second contact portion, causing the second contact portion to displace outward, and the first contact portion is driven to displace outward through the transition portion, so that the outer wall of the first contact portion can be squeezed against the heat conductor, thereby increasing the contact area and reducing thermal resistance. When the heat-conducting spring is assembled with the heat conductor and the heating element, the first contact portion cooperates with the transition portion and the second contact portion to enable the contact edge to produce elastic deformation, thereby preventing the heat-conducting spring from being unable to be assembled between the heating element and the heat conductor when there is a deviation in the size of the heating element and the heat conductor due to processing problems.

[0014] Preferably, the heating element is a ceramic graphene heating module containing graphene.

[0015] Preferably, the centers of the mounting holes on the heat conductor are distributed on concentric circles with the center of the heat conductor as the center.

[0016] This arrangement allows several heating elements to be arranged in concentric circles, thereby improving the uniformity of heat conduction.

[0017] Preferably, the number of the heating elements is less than or equal to the number of the mounting holes on the heat conductor. The number of heating elements can be flexibly set according to actual needs to improve applicability when increasing or decreasing the number of heating elements.

[0018] Preferably, the heat conductor is provided with a plurality of heat exchange holes, which are arranged along the axial direction of the heat conductor, and the heat conductor has a honeycomb structure. The heat exchange holes are evenly arranged to form a honeycomb mesh on the heat conductor, which can increase the contact area with the air to achieve sufficient heat exchange.

[0019] Preferably, a plurality of heating holes are also provided on the heating element, and the heating holes are extended along the axial direction of the heating element. The heating element has a honeycomb structure, and the surface of the heating element and the inner wall of the heating holes contain graphene, so that the heating element has good heating effect and heat transfer effect, and good thermal stability, so that the thermal power of the heating element is very stable during long-term use, and the heat is transferred to the heat conductor to the maximum extent.

[0020] Preferably, the thickness of the heat conductor along the axial direction is smaller than the thickness of the heating element along the axial direction.

[0021] This arrangement makes one end face of the heating element higher than the end face of the heat conductor on the same side, thereby forming a height difference between the end faces of the heating element and the heat conductor on the same side, and further forming an installation area between the heating element and the heat conductor. This is to facilitate the subsequent installation of the electrode sheath to provide an installation position for the electrode sheath, so that the connecting part on the electrode sheath can be clamped in the installation area formed due to the height difference between the heat conductor and the heating element.

[0022] Preferably, the heat transfer holes on the heat conductor are hexagonal holes. The hexagonal holes can ensure sufficient heat exchange area while also enhancing the structural strength of the heat conductor, thereby preventing the heat conductor from being damaged or deformed during use and transportation.

[0023] Preferably, the mounting holes include a central mounting hole disposed at the center of the heat conductor and at least one layer of circumferential mounting holes, each layer of circumferential mounting holes including at least two circumferential mounting holes, and the centers of the circumferential mounting holes in the same layer of circumferential mounting holes are equidistant from the center of the heat conductor. This arrangement allows the heating element to be movably disposed at the center of the heat conductor and at circumferential positions a certain distance from the center, thereby enabling the heating element to evenly transfer heat to the central region of the heat conductor and to various radial regions.

[0024] Preferably, the heat conductor is provided with multiple layers of circumferential mounting holes, which are evenly spaced along the radial direction of the heat conductor, that is, multiple circumferential mounting holes are provided along the radial direction of the heat conductor within the radial range of the heat conductor. This arrangement ensures that all areas of the heat conductor in the radial direction can receive heat transferred from the heating element.

[0025] Preferably, the extended surface of the first contact portion and the extended surface of the second contact portion are arranged parallel to each other, and the first contact portion and the second contact portion can both be in close contact with the components they are in contact with when subjected to external force.

[0026] Preferably, the transition portion is arranged obliquely relative to the first contact portion and the second contact portion.

[0027] Preferably, the first contact portion, the transition portion, and the second contact portion are all straight plate structures.

[0028] Preferably, the transition portion is an arc-shaped plate, so that there is an arc-shaped transition between the first contact portion and the second contact portion.

[0029] Preferably, the contact edge includes a plurality of spaced-apart unit contact portions, with a spacer area provided between each two adjacent unit contact portions, and each unit contact portion includes a first contact portion connected to the bending edge, a second contact portion away from the bending edge, and a transition portion connecting the first contact portion and the second contact portion.

[0030] Preferably, the width and height of each unit contact portion are equal, so as to ensure the uniformity of the heat conduction process of the unit contact portion, so that the heat conduction effect of any position of the contact portion is consistent. At the same time, the unit contact portion is provided to ensure that the external force received by the contact portion when in contact with the heat conductor and the heating element is transmitted to each unit contact portion, dispersing the external pressure received by the contact edge. At the same time, the unit contact portion will not be affected by other unit contact portions when elastically deformed by force, that is, multiple unit contact portions will not affect each other when subjected to force, so that the unit contact portions can all be in close contact with the respective contacting parts. If the contact edge is not provided with a spacing area, the elastic deformation of each area of ​​the contact edge will inevitably affect each other, thereby causing the contact edge of some areas to be unable to be in close contact with the heating element and the heat conductor, resulting in poor contact and the problem of large thermal resistance.

[0031] Preferably, the spacing between the spacers is equal along the circumferential direction, or gradually increases, or gradually decreases, or is irregularly distributed.

[0032] Preferably, the spacing area extends from the edge of the bent edge to the bottom of the contact edge.

[0033] Preferably, the bent edge is a ring-shaped part, and the contact edge is extended from the inner ring edge of the bent edge in a direction away from the bent edge.

[0034] Preferably, the bending edge is designed according to the heating element and heat conductor used in conjunction with it, and the cross-sectional shape of the bending edge can be triangular, circular or polygonal.

[0035] More preferably, the cross section of the bending edge is circular, that is, the projection of the bending edge in the axial direction is a circular ring.

[0036] Preferably, a notch area is provided on the bent edge, and the bent edge forms two oppositely disposed ends of the bent edge in the notch area.

[0037] With this arrangement, the notch area breaks the bent edge into an unclosed structure, thereby allowing the bent edge to also have circumferential elastic deformation capabilities. This arrangement allows the notch area to cooperate with the spacing area to adapt to heating elements and heat conductors with slightly varying sizes. In particular, the notch area arrangement allows the bent edge to have sufficient deformation capabilities when assembled between the heating element and the heat conductor, avoiding the problem of poor contact during installation leading to high thermal resistance. This prevents the bent edge from being unable to produce elastic deformation when it is a fully enclosed annular structure, thereby preventing the thermally conductive spring from being able to adapt to being assembled on heating elements and heat conductors with inconsistent sizes due to production errors.

[0038] Preferably, the notch region communicates with the spacer region.

[0039] This arrangement allows the entire thermally conductive spring to form an open structure from the bent edge to the contact edge in the notch area, ensuring that the bent edge of the thermally conductive spring can drive the contact edge to undergo circumferential elastic deformation when undergoing elastic deformation, so as to adapt to heating elements and heat conductors with slightly different sizes.

[0040] Preferably, an extension line of the center line of the notch area passes through the center of the bent edge.

[0041] Preferably, the connection between the bent edge and the first contact portion is an arc transition.

[0042] This arrangement can prevent stress concentration from occurring on the bending edge and the contact edge, ensuring that when the contact edge undergoes elastic deformation under the action of external force, the connection between the bending edge and the contact edge will not easily break due to stress concentration.

[0043] Preferably, the bent edge and the first contact portion are arranged at a right angle.

[0044] This arrangement facilitates the close fit of the bent edge against the upper end surface of the thermal conductor when the thermally conductive spring is inserted into the mounting hole of the thermal conductor, while also ensuring that the first contact portion is in close contact with the thermal conductor. Furthermore, when the contact edge is subjected to external force, the entire side surfaces of the first and second contact portions remain in close contact with their respective contacting components, thereby ensuring a tight fit of the contact edge.

[0045] Preferably, the angle at which the transition portion is bent relative to the first contact portion is equal to the angle at which the transition portion is bent relative to the second contact portion.

[0046] Preferably, the angle between the transition portion and the extended surface of the first contact portion is a, and the range of a is 0°<a≤30°, that is, the angle at which the transition portion is deflected relative to the first contact portion is a, and the angle between the transition portion and the extended surface of the second contact portion is b, and the range of b is 0°<b≤30°, that is, the angle at which the transition portion is deflected relative to the second contact portion is b.

[0047] Preferably, the heat-conducting spring is made of elastically deformable heat-conducting metal material.

[0048] More preferably, the thermally conductive spring is made of aluminum-based material, copper-based material or iron-based material.

[0049] Compared with the prior art, the present invention has achieved beneficial technical effects:

[0050] 1. The heating module in the present invention increases the contact area with the air by the heat conductor to fully exchange heat. According to actual needs, an appropriate number of heating elements are selected and installed on the heat conductor. The heat-conducting spring is installed in the buffer zone between the heating block mounting hole and the heating element. The heat on the heating element can be better transferred to the heat conductor so that the contact area between the heat conductor and the air can be fully exchanged with heat. The heating element is a ceramic graphene heating module containing graphene, so that the heating element has good heating effect and heat transfer effect, and good thermal stability, so that the thermal power of the heating element is very stable during long-term use, and the heat is transferred to the heat conductor to the maximum extent.

[0051] 2. During the assembly process of the thermally conductive spring in the present invention, the second contact portion is subjected to external force, and at the same time, the first contact portion is driven to move toward the outside of the contact edge through the transition portion, so that the contact edge can produce elastic deformation, so that the thermally conductive spring can adapt to heating elements and heat conductors with different sizes due to processing problems.

[0052] 3. During the assembly process of the thermally conductive spring in the present invention, the component in contact with the second contact portion squeezes the second contact portion, causing the second contact portion to move outward. At the same time, the second contact portion drives the transition portion to move, and then the transition portion drives the first contact portion to move outward, so that the outer wall of the first contact portion can squeeze the component in contact with it, so that the first contact portion and the second contact portion can both be tightly attached to the components in contact with each other when subjected to external force, thereby increasing the contact area and reducing thermal resistance.

[0053] 4. The thermally conductive springs of the present invention are provided with spacing areas between the unit contact parts, which can ensure that the external force exerted on the contact parts when in contact with the heat conductor and the heating element is transmitted to each unit contact part, dispersing the external pressure exerted on the contact edges. At the same time, when the unit contact parts are elastically deformed under force, they will not be affected by other unit contact parts, that is, multiple unit contact parts will not affect each other when under force, so that the unit contact parts can all be tightly attached to the components they are in contact with.

[0067] The present invention will be further described in detail below with reference to the accompanying drawings.

[0068] Example 1

[0069] A heating module includes: a heat conductor 2, a heating element 3 and a heat-conducting spring 1, a plurality of mounting holes 21 are provided on the heat conductor 2, a plurality of heating elements 3 are provided, and the heating element 3 is placed in the mounting holes 21; the heat-conducting spring 1 includes a bending edge 11 and a contact edge 12, the contact edge 12 is extended from the circumferential edge of the bending edge 11 in a direction away from the bending edge 11, and an angle is formed between the contact edge 12 and the bending edge 11, the contact edge 12 includes a first contact portion 121 connected to the bending edge 11, a second contact portion 123 away from the bending edge 11 and a transition portion 122 connecting the first contact portion 121 and the second contact portion 123, the extension surface of the first contact portion 121 and the extension surface of the second contact portion 123 are in different planes, and the contact edge 12 can produce elastic deformation relative to the bending edge 11 when subjected to force; the heat-conducting spring 1 is installed between the mounting hole 21 on the heat conductor 2 and the heating element 3. The heat conductor 2 can be used to increase the contact area with the air for sufficient heat exchange. The heating element 3 can be movably installed on the heat conductor 2. The heat-conducting spring 1 is installed in the buffer zone between the heating block mounting hole 21 and the heating element 3, which can realize better transfer of heat from the heating element 3 to the heat conductor 2 so that the heat conductor 2 and the air contact area can be fully exchanged with heat. At the same time, the heat-conducting spring 1 can avoid the problem of poor contact caused by inconsistent sizes when the heat conductor 2 and the heating element 3 are directly assembled, thereby reducing thermal resistance and improving thermal conductivity. At the same time, the heat-conducting spring 1 can also prevent the unreasonable gap between the heat conductor 2 and the heating element 3, causing the heating element 3 to rupture during production or transportation, or the heat conductor 2 to deform due to heat, causing the heating element 3 to rupture.

[0070] like Figure 5 and 6As shown, the contact edge 12 of the thermally conductive spring 1 is inserted into the mounting hole 21 of the thermal conductor 2, and the contact edge 12 of the thermally conductive spring 1 is inserted between the thermal conductor 2 and the heating element 3. The outer wall of the first contact portion 121 contacts the inner wall of the mounting hole 21 on the thermal conductor 2, and the bottom wall of the bent edge 11 contacts the upper end surface of the thermal conductor 2. At the same time, the contact edge 12 is sleeved on the heating element 3 so that the inner wall of the second contact portion 123 contacts the outer wall of the heating element 3, so that the thermally conductive spring 1 transfers the heat of the heating element 3 to the thermal conductor 2. After the bottom wall of the bent edge 11 contacts the upper end surface of the thermal conductor 2, the bent edge 11 overlaps the thermal conductor 2, thereby ensuring that the thermally conductive spring 1 can be firmly assembled in the mounting hole 21 of the thermal conductor 2, and the contact edge 12 is inserted between the thermal conductor 2 and the heating element 3, ensuring that the thermally conductive spring 1 transfers the heat of the heating element 3 to the thermal conductor 2. Because the bent edge 11 and the contact edge 12 are not in the same plane, when the contact edge 12 contacts the heating element 3 during assembly, the heating element 3 squeezes the second contact portion 123, causing the second contact portion 123 to displace outward. This, in turn, drives the first contact portion 121 outward via the transition portion 122, allowing the outer wall of the first contact portion 121 to squeeze against the heat conductor 2, thereby increasing the contact area and reducing thermal resistance. When the thermally conductive spring 1 is assembled with the heat conductor 2 and the heating element 3, the first contact portion 121 cooperates with the transition portion 122 and the second contact portion 123 to allow the contact edge 12 to undergo elastic deformation, preventing the thermally conductive spring 1 from being unable to be assembled between the heating element 3 and the heat conductor 2 due to dimensional deviations caused by processing problems.

[0071] The heat conductor 2 is provided with a plurality of heat exchange holes extending along the axial direction of the heat conductor 2. The heat conductor 2 has a honeycomb structure. The heat exchange holes are evenly arranged to form a honeycomb mesh on the heat conductor 2. The heat exchange holes can increase the contact area with the air to achieve sufficient heat exchange.

[0072] The heating element 3 is a ceramic graphene heating module containing graphene. Several heating holes 31 are also provided on the heating element 3, extending axially along the heating element 3. The heating element 3 has a honeycomb structure, and both the surface of the heating element 3 and the inner walls of the heating holes 31 contain graphene. This ensures that the heating element 3 has excellent heating and heat transfer effects and good thermal stability. This ensures that the heating element 3 maintains very stable thermal output during long-term use, maximizing heat transfer to the heat conductor 2.

[0073] The centers of the mounting holes 21 on the heat conductor 2 are all distributed on concentric circles with the center of the heat conductor 2 as the center. This arrangement allows several heating elements 3 to be arranged in concentric circles, thereby improving the uniformity of heat conduction. The mounting holes 21 include a central mounting hole 211 set at the center of the heat conductor 2 and at least one layer of circumferential mounting holes 212. Each layer of circumferential mounting holes 212 includes at least two circumferential mounting holes 212. The centers of the circumferential mounting holes 212 in the same layer of circumferential mounting holes 212 are equidistant from the center of the heat conductor 2. This arrangement allows the heating element 3 to be movably set at the center position of the heat conductor 2 and at circumferential positions at a certain distance from the center, so that the heating element 3 can evenly transfer heat to the central area of ​​the heat conductor 2 and various areas in the radial direction.

[0074] In this embodiment, the cross-sectional shape of the heat conductor 2 is circular, and seven mounting holes 21 are provided on the heat conductor 2, including a central mounting hole 211 provided at the center of the heat conductor 2 and six circumferential mounting holes 212 provided in the circumferential direction. The six circumferential mounting holes 212 are all at the same distance from the center of the heat conductor 2, and the distance between the centers of the six mounting holes 21 and the center of the heat conductor 2 is half the radius of the heat conductor 2.

[0075] The number of the heating elements 3 is less than or equal to the number of the mounting holes 21 on the heat conductor 2 . The number of the heating elements 3 can be flexibly set according to actual needs to improve applicability when increasing or decreasing the number of the heating elements 3 .

[0076] The thickness of the heat conductor 2 along the axial direction is smaller than the thickness of the heating element 3 along the axial direction. This arrangement makes one end face of the heating element 3 higher than the end face of the heat conductor 2 on the same side, thereby forming a height difference between the end faces of the heating element 3 and the heat conductor 2 on the same side, and further forming a mounting area between the heating element 3 and the heat conductor 2. This is to facilitate the subsequent installation of the electrode sheath to provide a mounting position for the electrode sheath, so that the connecting portion on the electrode sheath can be clamped in the mounting area formed by the height difference between the heat conductor 2 and the heating element 3.

[0077] The heat transfer holes 22 on the heat conductor 2 are hexagonal holes. The hexagonal holes can ensure sufficient heat exchange area while also enhancing the structural strength of the heat conductor 2 and preventing the heat conductor 2 from being damaged or deformed during use and transportation.

[0078] like Figure 3 and 4As shown, the thermally conductive spring 1 is a heat-conducting metal material that can be elastically deformed. In this embodiment, preferably, the thermally conductive spring 1 is an aluminum-based material, a copper-based material or an iron-based material. The first contact portion 121, the transition portion 122, and the second contact portion 123 on the thermally conductive spring 1 are all straight plate structures. The extension surface of the first contact portion 121 and the extension surface of the second contact portion 123 are arranged parallel to each other, and the first contact portion 121 and the second contact portion 123 can both be tightly attached to the components they are in contact with when subjected to external force. The transition portion 122 is arranged at an angle relative to the first contact portion 121 and the second contact portion 123. The angle at which the transition portion 122 is deflected relative to the first contact portion 121 is equal to the angle at which the transition portion 122 is deflected relative to the second contact portion 123. The angle between the transition portion 122 and the extended surface of the first contact portion 121 is a, and the range of a is 0°<a≤30°, that is, the angle at which the transition portion 122 is bent relative to the first contact portion 121 is a. The angle between the transition portion 122 and the extended surface of the second contact portion 123 is b, and the range of b is 0°<b≤30°, that is, the angle at which the transition portion 122 is bent relative to the second contact portion 123 is b.

[0079] The connection between the bent edge 11 and the first contact portion 121 is an arc transition. This arrangement prevents stress concentration from occurring between the bent edge 11 and the contact edge 12, and ensures that when the contact edge 12 is elastically deformed under the action of an external force, the connection between the bent edge 11 and the contact edge 12 will not easily break due to stress concentration. The bent edge 11 and the first contact portion 121 are arranged at a right angle. This arrangement facilitates the insertion of the heat-conducting spring 1 into the mounting hole 21 of the heat conductor 2, so that the bent edge 11 can fit tightly against the upper end face of the heat conductor 2, while also allowing the first contact portion 121 to fit tightly against the heat conductor 2. It also ensures that when the contact edge 12 is subjected to an external force, the entire side surfaces of the first contact portion 121 and the second contact portion 123 are in close contact with the respective contacting components, thereby ensuring the tightness of the contact edge 12.

[0080] like Figure 1 As shown, the contact edge 12 includes a plurality of spaced-apart unit contact portions, with a spacer 124 provided between each two adjacent unit contact portions. Each unit contact portion includes a first contact portion 121 connected to the bent edge 11, a second contact portion 123 away from the bent edge 11, and a transition portion 122 connecting the first contact portion 121 and the second contact portion 123. The spacer 124 extends from the edge of the bent edge 11 to the bottom of the contact edge 12.

[0081] The width and height of each unit contact part are equal, which can ensure the uniformity of the heat conduction process of the unit contact part, so that the heat conduction effect of any position of the contact part is consistent. At the same time, the unit contact part can ensure that the external force received by the contact part when in contact with the heat conductor 2 and the heating element 3 is transmitted to each unit contact part, dispersing the external pressure received by the contact edge 12. At the same time, the unit contact part will not be affected by other unit contact parts when it is elastically deformed under force, that is, multiple unit contact parts will not affect each other when under force, so that the unit contact parts can all be in close contact with the components they are in contact with. If the contact edge 12 is not provided with a spacing area 124, the elastic deformation of each area of ​​the contact edge 12 will inevitably affect each other, and then cause the contact edge 12 in some areas to be unable to be in close contact with the heating element 3 and the heat conductor 2, resulting in poor contact and the problem of high thermal resistance. The spacing of the spacing areas 124 is equal along the circumference, or gradually increases, or gradually decreases, or is irregularly distributed. In this embodiment, preferably, the spacing of the spacing areas 124 is equal.

[0082] The bending edge 11 is an annular member, and the contact edge 12 extends from the inner edge of the bending edge 11 in a direction away from the bending edge 11. The bending edge 11 is designed according to the heating element 3 and the heat conductor 2 used with it. The cross-sectional shape of the bending edge 11 can be triangular, circular, or polygonal. In this embodiment, the cross-section of the bending edge 11 is preferably circular, that is, the projection of the bending edge 11 in the axial direction is a circular ring.

[0083] A notch area 111 is provided on the bending edge 11, and the bending edge 11 forms two oppositely disposed ends of the bending edge 11 in the notch area 111. With this arrangement, the notch area 111 breaks the bending edge 11 into an unclosed structure, thereby enabling the bending edge 11 to also have circumferential elastic deformation capabilities. With this arrangement, the notch area 111 can cooperate with the spacer area 124 to adapt to the heating element 3 and the heat conductor 2 with slightly different sizes. In particular, the setting of the notch area 111 can enable the bending edge 11 to have sufficient deformation capabilities when assembled between the heating element 3 and the heat conductor 2, thereby avoiding the problem of poor contact during the installation process leading to high thermal resistance. When the bending edge 11 is a fully enclosed annular structure, the bending edge 11 cannot produce elastic deformation, thereby preventing the thermally conductive spring 1 from being adapted to be assembled on the heating element 3 and the heat conductor 2 with inconsistent sizes due to production errors.

[0084] The extension of the centerline of the notch area 111 passes through the center of the bent edge 11, and the notch area 111 on the bent edge 11 is connected to the spacer area 124. This arrangement forms an open structure in the notch area 111 from the bent edge 11 to the contact edge 12, ensuring that the bent edge 11 of the thermally conductive spring 1 can drive the contact edge 12 to undergo circumferential elastic deformation when it undergoes elastic deformation, thereby adapting to slightly different sizes of the heating element 3 and the heat conductor 2.

[0087] In this embodiment, the bent edge 11 and the first contact portion 121 are arranged at an obtuse angle. When the thermally conductive spring 1 and the heat conductor 2 are assembled, the bent edge 11 can be pressed tightly against the thermally conductive spring 1 by external force.

[0090] In this embodiment, the bending edge 11 is a ring-shaped member, and the contact edge 12 is extended from the outer ring edge of the bending edge 11 in a direction away from the bending edge 11 .

[0092] Based on the first embodiment, this embodiment differs from the first embodiment in that:

[0093] In this embodiment, the transition portion 122 is an arc-shaped plate, so that an arc-shaped transition is formed between the first contact portion 121 and the second contact portion 123 .

[0094] Example 5

[0095] Based on the first embodiment, this embodiment differs from the first embodiment in that:

[0096] In this embodiment, the heat conductor 2 is provided with multiple layers of circumferential mounting holes, which are evenly spaced along the radial direction of the heat conductor 2. That is, multiple circumferential mounting holes are provided along the radial direction of the heat conductor 2 within the radial range of the heat conductor 2. This arrangement ensures that all radial regions of the heat conductor 2 can receive heat transferred from the heating element 3.
