Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a heating body, a manufacturing method thereof and a warmer. BACKGROUND

[0002] In the related art, the heating body usually adopts the way of embedding the heating element into the heat dissipation element to realize heating and heat exchange. However, the heating element is directly arranged in the heat dissipation element, and the connection part of the heating element and the heat dissipation element is prone to looseness. In addition, the connection part of the heating element and the heat dissipation element is not tightly fitted, so that there is a large thermal resistance at the connection part of the heating element and the heat dissipation element, and the heat conduction efficiency of the heating body is low, which has the problem of high energy consumption. SUMMARY

[0003] The present application aims to at least solve one of the problems in the prior art.

[0004] To this end, the first aspect of the present application provides a heating body.

[0005] The second aspect of the present application provides a warmer.

[0006] The third aspect of the present application provides a manufacturing method of a heating body.

[0007] The first aspect of the present application provides a heating body, comprising: a heating element, a side wall of the heating element is provided with a recess; a heat dissipation element, the heat dissipation element is sleeved on the heating element; a connecting element, at least a part of the connecting element is located in the recess, and the heat dissipation element and the heating element are connected into one body through the connecting element.

[0008] The heating body provided by the present application comprises a heating element, a heat dissipation element and a connecting element. The side wall of the heating element is provided with a recess, and at least a part of the connecting element is arranged in the recess; the heat dissipation element is sleeved on the heating element, and the heat dissipation element and the heating element are connected into one body through the connecting element. When the heating body is running, at least a part of the heat generated by the heating element can be conducted to the heat dissipation element through the connecting element, and then the heat dissipation element dissipates heat to the surrounding, so as to achieve the effect of warming and heating. Specifically, the number of heating elements can be designed according to actual conditions, and one or more than two can be set.

[0009] In particular, the heat dissipation element and the heating element are connected into one body through the connecting element, at least a part of the heat dissipation element directly contacts the heating element, so that there is no heat insulation gap at the position of the connecting element. In this way, at least a part of the heat generated by the heating element is conducted to the heat dissipation element through the connecting element during the operation of the heating body, which improves the heat conduction efficiency of the heat conduction from the heating element to the heat dissipation element, so that the heat is efficiently and quickly conducted to the heat dissipation element, thereby reducing the energy consumption of the heating body.

[0010] Further, the heat dissipation member and the heat generating member are connected as a whole through the connecting member. The connecting member can realize stable connection of the heat dissipation member and the heat generating member, and make the heat generating member and the heat dissipation member in close contact (which can be direct contact of the heat dissipation member and the heat generating member, or indirect contact of the heat generating member and the heat dissipation member through the connecting member). In this way, during daily use of the heat generating body, the firm connection between the heat dissipation member and the heat generating member can be ensured, and the situation that the heat dissipation member and the heat generating member are loose at the connection position can be avoided, thereby ensuring the safe use of the heat generating body.

[0011] Further, the setting of the recess on the heat generating body is beneficial to the processing and manufacturing of the heat generating body, and in particular, is beneficial to the integrated processing of the heat generating member and the heat dissipation member. Specifically, during the manufacturing of the heat generating member, at least a part of the connecting member can be arranged in the recess first, and then the heat dissipation member is sleeved on the heat generating member. Through the setting of the recess, the connecting member can be applied to the heat generating member before the heat dissipation member is sleeved, and it is ensured that the user can easily sleeve the heat dissipation member on the heat generating member subsequently, which reduces the manufacturing difficulty of the heat generating member and improves the manufacturing efficiency of the heat generating member.

[0012] In addition, the present application sets the recess on the side of the heat generating body, and at least a part of the connecting member is arranged in the recess, which can reduce the risk of deformation of the heat dissipation member during assembly, so as to ensure to improve the heat dissipation efficiency of the heat dissipation member. Moreover, the stability of the connecting member is improved, and during the sleeving process of the heat generating body and the heat dissipation member, the risk of sliding or scraping off of the connecting member can be reduced, and the firmness of the connection is improved. In addition, the recess is arranged on the side of the heat generating body, and the heat transfer rate of the heat generating member through the connecting member is different from the heat transfer rate of the heat generating member directly contacting the heat dissipation member, which can reduce the heat transfer through the connecting member, reduce the risk of falling off of the connecting member and the heat generating member or the heat dissipation member due to heat concentration, and improve the connection strength.

[0013] Therefore, in the heat generating member provided by the present application, the recess is arranged on the side of the heat generating body, and at least a part of the connecting member is arranged in the recess, so that the heat dissipation member and the heat generating member are connected as a whole through the connecting member. In this way, on the one hand, the heat transfer effect between the heat generating member and the heat dissipation member is improved, the heat dissipation effect of the heat dissipation member is improved, and the energy consumption of the heat generating member is reduced, and on the other hand, the risk of loosening between the heat dissipation member and the heat generating member is reduced, and the yield of the heat generating body is improved.

[0014] In some possible designs, the connecting member includes a hot melt member.

[0015] In this design, the connecting member comprises a hot-melt member which can melt after reaching a melting point and can connect the heat-dissipating member and the heat-generating member into one body after cooling. Specifically, the hot-melt member is in solid state at room temperature, and the user can place the hot-melt member into the recess. After the heat-dissipating member is sleeved onto the heat-generating member, the heat-generating member is powered to heat the hot-melt member, so that the hot-melt member melts under heat. Then, the heat-generating member is powered off, and the temperature of the hot-melt member gradually decreases and cools into solid state, thereby connecting the heat-dissipating member and the heat-generating member into one body.

[0016] In particular, after the hot-melt member melts under heat, the liquid hot-melt member can only remain in the recess, or part of the hot-melt member can flow to a position outside the recess and connect the heat-dissipating member and the heat-generating member into one body outside the recess. However, in either case, there is no heat insulation gap at the position of the hot-melt member, thereby ensuring effective heat conduction and firm connection between the heat-generating member and the heat-dissipating member.

[0017] It should be noted here that the melting point of the hot-melt member is higher than the heat generation temperature of the heat-generating member in daily use. That is, in the process of connecting the heat-generating member and the heat-dissipating member, the power-on voltage of the heat-generating member is greater than the daily working voltage, thereby making the heat generation temperature of the heat-generating member higher than the daily heat generation temperature. In this way, during daily use, the hot-melt member will not melt again.

[0018] In some possible designs, the connecting member comprises a welding member.

[0019] In this design, the connecting member comprises a welding member which can melt after reaching a melting point and can connect the heat-dissipating member and the heat-generating member into one body after cooling. Specifically, the welding member is in solid state at room temperature, and the user can place the welding member into the recess. After the heat-dissipating member is sleeved onto the heat-generating member, the heat-generating member is powered to heat the welding member, so that the welding member melts under heat. Then, the heat-generating member is powered off, and the temperature of the welding member gradually decreases and cools into solid state, thereby connecting the heat-dissipating member and the heat-generating member into one body. Specifically, the welding member can be a brazing agent (such as solder paste).

[0020] In particular, after the welding member melts under heat, the liquid welding member can only remain in the recess, or part of the welding member can flow to a position outside the recess and connect the heat-dissipating member and the heat-generating member into one body outside the recess. However, in either case, there is no heat insulation gap at the position of the welding member, thereby ensuring effective heat conduction and firm connection between the heat-generating member and the heat-dissipating member.

[0021] It should be noted that the melting point of the connecting piece is higher than the heating temperature of the heating piece in the daily use process. That is, in the process of connecting the heating piece and the heat dissipation piece, the power-on voltage of the heating piece is greater than the daily working voltage, so that the heating temperature of the heating piece is higher than the daily heating temperature. In this way, in the daily use process, the connecting piece will not be melted again.

[0022] In some possible designs, the melting point of the connecting piece is lower than the melting point of the heating piece, and the melting point of the connecting piece is lower than the melting point of the heat dissipation piece.

[0023] In this design, the melting point of the connecting piece is lower than the melting point of the heating piece, and also lower than the melting point of the heat dissipation piece. In this way, in the process of connecting the heating piece and the heat dissipation piece, the heating temperature is ensured to reach the melting point of the connecting piece, and is lower than the melting point of the heating piece and the melting point of the heat dissipation piece, so that the heating piece and the heat dissipation piece are connected as a whole, and it is ensured that the heating piece and the heat dissipation piece will not be deformed during heating.

[0024] In some possible designs, the side wall of the heating piece includes a first region and a second region, the connecting piece is located in the first region, and the part of the heat dissipation piece corresponding to the recess is in contact with the connecting piece, and the part of the heat dissipation piece corresponding to the second region is in contact with the second region.

[0025] In this design, the side wall of the heating piece includes a first region and a second region, the recess is arranged in the first region, and the second region does not have the above-mentioned recess. In addition, the part of the heat dissipation piece corresponding to the recess is in contact with the connecting piece, and the part of the heat dissipation piece corresponding to the second region is in contact with the second region; that is, the first region of the heating piece is in contact with the connecting piece, and the connecting piece is further in contact with the heat dissipation piece; the second region of the heating piece is directly in contact with the heat dissipation piece. Specifically, in the process of manufacturing the heating piece, the connecting piece in liquid state is left in the recess, and the connecting piece connects the heat dissipation piece and the heating piece inside the recess.

[0026] In this way, during the operation of the heating body, the heat released from the first region of the heating body can be at least conducted to the heat dissipation piece through the connecting piece, and the heat released from the second region of the heating body can be at least directly conducted to the heat dissipation piece, so that the risk of heat concentration at the position of the connecting piece can be effectively reduced, and the risk of the heat dissipation piece falling off is reduced. Moreover, since the connecting piece directly connects the heat dissipation piece and the heating piece in the first region, and the heating piece and the heat dissipation piece are directly connected in the second region, the heat transfer efficiency between the heating piece and the heat dissipation piece is improved, the heat accumulation between the heating piece and the heat dissipation piece is avoided, and the heating efficiency of the heating body is improved.

[0027] In some possible designs, the side wall of the heating piece includes a first region and a second region, and the recess is located in the first region; the connecting piece is located in the first region and the second region, and the heat dissipation piece is in contact with the connecting piece.

[0028] In the design, the side wall of the heat generating member comprises a first region and a second region, the recess is arranged in the first region, and the second region is not provided with the recess. In addition, the connecting member is located in the first region and the second region and is connected to the heat generating member and the heat dissipating member at the same time. Specifically, in the process of manufacturing the heat generating member, part of the liquid connecting member remains in the recess, and the other part flows outside the recess, so that the connecting member connects the heat dissipating member and the heat generating member inside and outside the recess.

[0029] In this way, during the operation of the heat generating body, the heat generated by the heat generating body from the first region and the second region can be conducted to the heat dissipating member at least through the connecting member. Moreover, since the connecting member directly connects the heat dissipating member and the heat generating member in the first region and the second region, the heat transfer efficiency between the heat generating member and the heat dissipating member is improved, the heat accumulation between the heat generating member and the heat dissipating member is avoided, and the heat generating efficiency of the heat generating body is improved.

[0030] In some possible designs, the heat dissipating member comprises: a fin, the fin is provided with a mounting hole, and the heat generating member is arranged in the mounting hole; and a flange, the flange is connected to the edge of the mounting hole, and the flange is connected to the heat generating member through the connecting member.

[0031] In the design, the heat dissipating member comprises a fin and a flange. The fin is provided with a mounting hole, and the edge of the mounting hole is provided with a flange. The heat generating member is arranged in the mounting hole, and the flange is connected to the heat generating member through the connecting member. That is, in the heat generating body provided by the application, the heat dissipating member is connected to the heat generating member through the flange, and the heat dissipating member dissipates heat to the surrounding environment through the fin to achieve the effect of heating. Specifically, the flange and the fin are in an integrated structure. Specifically, the heat dissipating member can be an aluminum heat dissipating fin.

[0032] In particular, through the arrangement of the flange, on the one hand, the connecting area between the heat dissipating member and the heat generating member can be ensured, and in particular, the effective connecting area of the connecting member can be ensured; on the other hand, the contact area between the heat dissipating member and the heat generating member can be ensured, so as to further improve the heat transfer efficiency between the heat generating member and the heat dissipating member.

[0033] Specifically, the number of fins is multiple, and each fin is provided with a mounting hole and a flange. In addition, the heat generating member is arranged in multiple fins, so as to improve the heat dissipation area of the heat generating body and improve the heating efficiency of the heat generating body.

[0034] In some possible designs, the heat generating member comprises: a heat generating pipe, a recess is arranged on the heat generating pipe, and the heat dissipating member is connected to the heat generating pipe through the connecting member; a heat generating element, arranged in the heat generating pipe; and an insulating member, arranged in the heat generating pipe, and the heat generating element is isolated from the heat generating pipe through the insulating member.

[0035] In the design, the heat generating member comprises a heat generating tube, a heat generating element and an insulating member. The recess is arranged on the side wall of the heat generating tube, and the heat dissipating member is connected with the heat generating tube as a whole through the connecting member. The heat generating element is arranged inside the heat generating tube and can be used to release heat when powered on. The insulating member is filled inside the heat generating tube, and the heating wire is isolated from the heat generating tube through the insulating member. In addition, the insulating member is a heat conducting member and can efficiently conduct the heat generated by the heat generating element to the heat generating tube. Specifically, the heat generating tube of the heat generating member and the folded edge of the heat dissipating member are connected as a whole through the connecting member.

[0036] In particular, the heat generating element and the insulating member are arranged inside the heat generating tube, thereby providing a certain protection for the heat generating element and the insulating member through the heat generating tube. Moreover, the heat generating tube is connected with the heat generating tube as a whole through the connecting member, thereby ensuring the connection firmness of the heat generating member and the heat dissipating member, and improving the heat transfer efficiency between the heat generating tube and the heat dissipating member to improve the heat generating efficiency of the heat generating body.

[0037] Further, the insulating member is located at least between the heat generating element and the heat generating tube, thereby providing a good insulation effect, thereby avoiding the occurrence of electric leakage during the use of the heat generating body. Moreover, the insulating member is a heat conducting member, thereby improving the heat transfer efficiency between the heat generating element and the heat generating tube to improve the heat generating efficiency of the heat generating body.

[0038] Specifically, the heat generating tube can be a stainless steel heat generating tube, and the insulating member can be magnesium oxide powder.

[0039] In some possible designs, the heat generating element is located at the center of the heat generating tube.

[0040] In the design, the heat generating element is located at the center of the heat generating tube and extends along the axial direction of the heat generating tube. In this way, the distance from the heat generating element to the side wall of the heat generating tube is equal, thereby ensuring the uniform heating of the heat generating body in the circumferential direction of the heat generating tube.

[0041] In some possible designs, the heat generating element is a heating wire, and the heating wire extends in a spiral shape in the axial direction of the heat generating tube.

[0042] In the design, the heat generating element is a heating wire. In addition, the heating wire extends in a spiral shape in the axial direction of the heat generating tube. In this way, under the condition that the axial dimension of the heat generating tube is constant, the length of the heating wire located inside the heat generating tube can be increased, the heat generating capacity of the heating wire is improved, and the heat generating efficiency of the heat generating body is improved.

[0043] In some possible designs, the distance from the center of the heat generating element to the side wall of the heat generating tube is a first size, the distance from the center of the heat generating element to the bottom wall of the recess is a second size, and the difference between the first size and the second size is less than or equal to 2 mm.

[0044] In the design, the center of the heating element to the side wall of the heating tube has a first size, the center of the heating element to the bottom wall of the recess has a second size, and the difference between the first size and the second size is greater than 0 mm and less than or equal to 2 mm. In particular, during the operation of the heating body, the heat generated by the heating element is conducted to the recess and the side wall of the heating tube, respectively. The first size of the center of the heating element to the side wall of the heating tube and the second size of the center of the heating element to the bottom wall of the recess are optimized in the present application, so that the difference between the first size and the second size is less than or equal to 2 mm.

[0045] In this way, by limiting the difference between the first size and the second size, the difference in heat transferred to the bottom wall of the recess and the side wall of the heating tube is within a certain range, thereby ensuring that the temperature difference between the recess and the side wall of the heating tube is within a certain range, avoiding the case that the local temperature of the heating element is too high, and reducing the possibility of heat concentration in the recess, thereby reducing the risk of the connection and the heat dissipation falling off, while ensuring the thermal efficiency of the heating body.

[0046] In some possible designs, the recess has a third size, the center of the heating element to the side wall of the heating tube has a first size, and the ratio of the third size to the first size is greater than or equal to 1 / 2 and less than or equal to 2 / 3.

[0047] In the design, the recess has a third size, the center of the heating element to the side wall of the heating tube has a first size, and the ratio of the third size to the first size is greater than or equal to 1 / 2 and less than or equal to 2 / 3. In particular, during the operation of the heating body, the heat generated by the heating element is conducted to the recess and the side wall of the heating tube, respectively. The ratio of the third size to the first size affects the amount of heat conducted to the recess and the temperature difference between the recess and the side wall of the heating tube. Therefore, the first size of the center of the heating element to the side wall of the heating tube and the third size of the recess are optimized in the present application, so that the ratio of the third size to the first size is greater than or equal to 1 / 2 and less than or equal to 2 / 3.

[0048] In this way, by limiting the ratio of the third size to the first size, the difference in heat transferred to the bottom wall of the recess and the side wall of the heating tube is within a certain range, thereby ensuring that the temperature difference between the recess and the side wall of the heating tube is within a certain range, avoiding the case that the local temperature of the heating element is too high.

[0049] In some possible designs, the recess has a third size, and the third size is less than or equal to 2 mm.

[0050] In the design, the recessed size of the recess is a third size. The third size is greater than 0 mm and less than or equal to 2 mm. In this way, on the basis of ensuring that the connecting piece can be placed, the recessed size of the recess is prevented from being too large, so that the heat conducted to the recess by the heat generating element is too large, and the heat generating element is not uniformly heated.

[0051] In some possible designs, the recess includes a bottom wall, a first side wall and a second side wall, and the first side wall and the second side wall are connected to opposite sides of the bottom wall.

[0052] In the design, the recess includes a bottom wall, a first side wall and a second side wall. The bottom wall of the recess is opposite the opening of the recess, the first side wall and the second side wall are arranged on opposite sides of the bottom wall and connected to the bottom wall.

[0053] In some possible designs, the size of the opening of the recess is greater than or equal to 1 mm and less than or equal to 5 mm in the circumferential direction of the heat generating element.

[0054] In the design, the size of the opening of the recess is greater than or equal to 1 mm and less than or equal to 5 mm in the circumferential direction of the heat generating element. In this way, the size of the opening of the recess is appropriate in the circumferential direction of the heat generating element, and the connecting piece is conveniently placed in the recess during manufacturing of the heat generating body. Specifically, the opening of the recess is arranged opposite the bottom wall of the recess.

[0055] In addition, the speed at which the heat generated by the heat generating element is transmitted to the heat dissipating element through the connecting piece is different from the speed at which the heat generated by the heat generating element is directly transmitted to the heat dissipating element, and heat concentration phenomenon is prone to occur at the connecting piece. Therefore, the opening of the recess is optimized in the present application to prevent the opening of the recess from being too large, so that the falling off between the connecting piece and the heat generating element or the heat dissipating element is reduced, and the fastening of the connection is improved.

[0056] Specifically, when the connecting piece uses soldering flux such as soldering paste, the soldering flux is filled by a soldering machine. In the circumferential direction of the heat generating element, the size L4 of the opening of the recess is greater than or equal to 1 mm and less than or equal to 5 mm, and the filling of the connecting piece is facilitated, so as to improve the manufacturing efficiency of the heat generating body.

[0057] In some possible designs, the size of the bottom wall is greater than or equal to 1 mm and less than or equal to 3 mm in the circumferential direction of the heat generating element.

[0058] In the design, the size of the bottom wall is greater than or equal to 1 mm and less than or equal to 3 mm in the circumferential direction of the heat generating element. In this way, the size of the opening of the recess is appropriate in the circumferential direction of the heat generating element, and the connecting piece is conveniently placed in the recess during manufacturing of the heat generating body. Specifically, the opening of the recess is arranged opposite the bottom wall of the recess.

[0059] In some possible design, the first included angle between the first side wall and the bottom wall is greater than or equal to 90°.

[0060] In this design, the first included angle is formed between the first side wall and the bottom wall. The first included angle is greater than or equal to 90°. In this way, the first included angle is optimized to have a flared shape, which facilitates the filling of the connecting member into the recess during the manufacturing of the heating body.

[0061] In some possible design, the second included angle between the second side wall and the bottom wall is greater than or equal to 90°.

[0062] In this design, the second included angle is formed between the second side wall and the bottom wall. The second included angle is greater than or equal to 90°. In this way, the second included angle is optimized to have a flared shape, which facilitates the filling of the connecting member into the recess during the manufacturing of the heating body.

[0063] In some possible design, the number of recesses is one.

[0064] In this design, the number of recesses can be one. In this case, the recess extends along the axial direction of the heating member, and the connecting member is filled into the recess to connect the heating member and the heat-dissipating member into one.

[0065] In some possible design, the number of recesses is at least two, and the at least two recesses are evenly distributed on the side wall of the heating member.

[0066] In this design, the number of recesses can be at least two. In this case, the at least two recesses are evenly distributed along the circumferential direction of the heating member, and each recess extends along the axial direction of the heating member. In this way, the heating member and the heat-dissipating member have multiple connection positions in the circumferential direction, which improves the connection strength and stability of the heating member and the heat-dissipating member.

[0067] Further, since the second dimension of the recess to the heating element is smaller than the first dimension of the heating element to the side wall of the heating pipe, the temperature of the recess is relatively high when the heating body is in operation, which improves the uniformity of the heating body in operation.

[0068] The second aspect of the present application provides a warmer, which comprises the heating body according to the first aspect of the present application.

[0069] The second aspect of the present application provides a warmer, which comprises the heating body according to the first aspect of the present application. Therefore, the warmer has all the beneficial effects of the heating body, which will not be described in detail here.

[0070] Further, the warmer further comprises an air duct structure, the air duct structure comprising an air inlet and an air outlet connected in series, and the heating body is arranged in the air duct structure. During operation of the warmer, external air enters the air duct structure from the air inlet, passes through the heating body, and is discharged from the air outlet, and then warm air is discharged into the environment. In this way, heat exchange is achieved to achieve the effect of temperature rise.

[0071] The third aspect of the present application provides a manufacturing method of a heating body, which is used for manufacturing the heating body of the first aspect of the present application. The manufacturing method comprises: filling the connecting piece into the recess of the heating piece; sleeving the heat-dissipating piece on the heating piece; electrifying the heating piece to melt the connecting piece; and de-energizing the heating piece to solidify the connecting piece, so as to connect the heating piece and the heat-dissipating piece into one.

[0072] The manufacturing method of the heating body of the third aspect of the present application can be used for manufacturing the heating body of the first aspect of the present application. Specifically, in the process of manufacturing the heating body, first, the connecting piece is filled into the recess of the heating piece; then, the heat-dissipating piece is sleeved on the heating piece, and the connecting piece is in contact with the heating piece and the heat-dissipating piece; then, the heating piece is electrified to generate heat, and the heat melts the connecting piece; and then, the heating piece is de-energized to stop heating, and the connecting piece gradually solidifies and connects the heating piece and the heat-dissipating piece into one.

[0073] In this way, the heating body manufactured by the present application can ensure that there is no thermal insulation gap at the position of the connecting piece. In this way, at least part of the heat generated by the heating piece is conducted to the heat-dissipating piece through the connecting piece during operation of the heating body, which improves the heat transfer efficiency from the heating piece to the heat-dissipating piece, so that the heat is efficiently and quickly conducted to the heat-dissipating piece, thereby reducing the energy consumption of the heating body.

[0074] In addition, the heating body manufactured by the present application can realize stable connection of the heat-dissipating piece and the heating piece through the connecting piece, and ensure close contact between the heating piece and the heat-dissipating piece (which can be direct contact or indirect contact through the connecting piece). In this way, during daily use of the heating body, the firm connection between the heat-dissipating piece and the heating piece can be ensured, and the situation that the connection between the heat-dissipating piece and the heating piece is loose can be avoided, thereby ensuring the safe use of the heating body.

[0075] Specifically, the connecting piece can be a hot melt piece or a welding piece. Moreover, the melting point of the connecting piece is higher than the heating temperature of the heating piece in the daily use process. That is, in the process of connecting the heating piece and the heat dissipation piece, the power-on voltage of the heating piece is greater than the daily working voltage, so that the heating temperature of the heating piece is higher than the daily heating temperature. In this way, in the daily use process, the connecting piece will not be melted again. For example, when the connecting piece is soldering paste, the heating soldering paste is greater than 400 DEG C after the heating piece is powered on.

[0076] In some possible designs, before the heat dissipation piece and the heating piece are connected by the connecting piece, the process further includes: stamping the flange of the heat dissipation piece so that the flange is attached to the heating piece.

[0077] In this design, after the heat dissipation piece is sleeved on the heating piece, the flange of the heat dissipation piece is first stamped, and then the heating piece is powered on. In this way, in the process of first stamping the flange of the heat dissipation piece, the flange of the heat dissipation piece can be attached to the heating piece as much as possible. In the process of subsequently heating the connecting piece, the connecting piece can contact the heat dissipation piece and the heating piece at the same time, and the heat dissipation piece and the heating piece can also be in contact as much as possible at the position where the connecting piece is not connected, thereby reducing the possibility of a heat insulation gap between the heat dissipation piece and the heating piece, improving the heat transfer efficiency of heat conduction from the heating piece to the heat dissipation piece, and enabling heat to be efficiently and quickly conducted to the heat dissipation piece, thereby reducing the energy consumption of the heating body.

[0078] Specifically, the user can manually stamp the flange of the heat dissipation piece, or a related stamping device can be used to stamp the flange of the heat dissipation piece.

[0095] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0096] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0097] The following reference Figures 1 to 12 This describes a heating element 100 and its manufacturing method, as well as a heater, provided according to some embodiments of the present invention.

[0098] like Figure 1 ,Figure 2 and Figure 3 As shown, the first embodiment of the present invention proposes a heating element 100, including: a heating element 102, a heat dissipation element 106, and a connecting element (not shown in the figure).

[0099] Among them, such as Figure 5 As shown, the heating element 102 has a recess 104 on its side wall, and at least a portion of the connector is disposed within the recess 104. The heat dissipation element 106 is sleeved on the heating element 102, and the heat dissipation element 106 and the heating element 102 are connected as one unit by the connector. When the heating element 100 is running, at least a portion of the heat generated by the heating element 102 can be conducted to the heat dissipation element 106 through the connector, and then the heat dissipation element 106 can quietly dissipate heat to the surroundings, achieving the effect of heating.

[0100] Specifically, such as Figure 4 and Figure 10 As shown, the number of heating elements 102 can be designed according to the actual situation, and one or more can be set.

[0101] Specifically, such as Figure 5 As shown, the recess 104 can be a groove provided on the side wall of the heating element 102.

[0102] In particular, such as Figure 5 As shown, the heat sink 106 and the heat generator 102 are connected as a single unit via a connector. At least a portion of the heat sink 106 is in direct contact with the heat generator 102, resulting in no heat insulation gap at the location of the connector. Thus, during the operation of the heating element 100, at least a portion of the heat generated by the heat generator 102 is conducted to the heat sink 106 through the connector, improving the heat transfer efficiency from the heat generator 102 to the heat sink 106. This allows for efficient and rapid heat transfer to the heat sink 106, thereby reducing the energy consumption of the heating element 100.

[0103] Furthermore, such as Figure 5 As shown, the heat sink 106 and the heating element 102 are connected as a single unit via a connector. The connector ensures a stable connection between the heat sink 106 and the heating element 102, and guarantees close contact between them (either direct contact or indirect contact via the connector). This ensures a secure connection between the heat sink 106 and the heating element 102 during normal use, preventing loosening and thus guaranteeing the safe operation of the heating element 100.

[0104] Furthermore, such as Figure 5As shown, the setting of the recess 104 on the heating body 100 is beneficial to the processing and manufacturing of the heating body 100, in particular, is beneficial to the integrated processing of the heating element 102 and the heat dissipation element 106. Specifically, in the process of manufacturing the heating element 102, at least a part of the connecting element can be first arranged in the recess 104, and then the heat dissipation element 106 is sleeved on the heating element 102. Through the setting of the recess 104, the connecting element can be applied to the heating element 102 before the heat dissipation element 106 is sleeved, and it is ensured that the user can easily sleeve the heat dissipation element 106 on the heating element 102, which reduces the manufacturing difficulty of the heating element 102 and improves the manufacturing efficiency of the heating element 102.

[0105] In addition, the present application sets the recess 104 on the side of the heating body 100, and at least a part of the connecting element is arranged in the recess 104, which can reduce the risk of deformation of the heat dissipation element 106 during assembly to ensure the heat dissipation efficiency of the heat dissipation element 106. And improve the stability of the connecting element, in the process of sleeving the heating body 100 and the heat dissipation element 106, the risk of sliding or scraping off the connecting element can be reduced, and the firmness of the connection can be improved. In addition, the recess 104 is arranged on the side of the heating body 100, and the heat transfer rate of the heating element 102 through the connecting element is different from the direct contact between the heating element 102 and the heat dissipation element 106, which can reduce the heat transfer through the connecting element, reduce the risk of the connecting element and the heating element 102 or the heat dissipation element 106 falling off due to heat concentration, and improve the connection strength.

[0106] Therefore, in the heating element 102 provided in the present embodiment, the recess 104 is arranged on the side of the heating body 100, and at least a part of the connecting element is arranged in the recess 104, so that the heat dissipation element 106 and the heating element 102 are connected as a whole through the connecting element. In this way, on the one hand, the heat transfer effect between the heating element 102 and the heat dissipation element 106 is improved, thereby reducing the energy consumption of the heating element 102, and on the other hand, the risk of loosening between the heat dissipation element 106 and the heating element 102 is reduced.

[0107] The second embodiment of the present application provides a heating body 100, which is further based on the first embodiment:

[0108] The connecting element includes a hot melt element (not shown in the figure), which can melt after reaching the melting point, and after cooling, the heat dissipation element 106 and the heating element 102 can be connected as a whole. Specifically, the hot melt element is in a solid state at room temperature, and the user can place the hot melt element in the recess 104. After the heat dissipation element 106 is sleeved on the heating element 102, the heating element 102 is powered to heat the hot melt element, so that the hot melt element is heated and melted. Then, the heating element 102 is powered off, and the temperature of the hot melt element gradually decreases and cools to a solid state, thereby connecting the heat dissipation element 106 and the heating element 102 as a whole.

[0109] Particularly, after the hot-melt member is heated and melted, the liquid hot-melt member can be left only in the recess 104, or part of the hot-melt member can flow to a position outside the recess 104 and connect the heat-dissipating member 106 and the heat-generating member 102 integrally outside the recess 104. However, in either case, the position where the hot-melt member is located does not have a heat-insulating gap, thereby ensuring effective heat conduction and firm connection between the heat-generating member 102 and the heat-dissipating member 106.

[0110] In addition, the melting point of the connecting member is lower than the melting point of the heat-generating member 102 and the melting point of the heat-dissipating member 106. In this way, during the process of connecting the heat-generating member 102 and the heat-dissipating member 106, the heating temperature is ensured to reach the melting point of the connecting member and be lower than the melting point of the heat-generating member 102 and the melting point of the heat-dissipating member 106, so that the heat-generating member 102 and the heat-dissipating member 106 are connected integrally, and it is ensured that the heat-generating member 102 and the heat-dissipating member 106 do not deform during the heating process.

[0111] It should be noted here that the melting point of the hot-melt member is higher than the heat generation temperature of the heat-generating member 102 during daily use. That is, during the process of connecting the heat-generating member 102 and the heat-dissipating member 106, the power supply voltage of the heat-generating member 102 is greater than the daily working voltage, so that the heat generation temperature of the heat-generating member 102 is higher than the daily heat generation temperature. In this way, during daily use, the hot-melt member will not be melted again.

[0112] In addition, the heat-generating body 100 proposed in the embodiment also has all the beneficial effects of the heat-generating body 100 proposed in the first embodiment, which can improve the heat conduction effect between the heat-generating member 102 and the heat-dissipating member 106, thereby reducing the energy consumption of the heat-generating member 102, and can reduce the risk of loosening between the heat-dissipating member 106 and the heat-generating member 102, which will not be discussed in detail here.

[0113] A third embodiment of the present application proposes a heat-generating body 100, which is further based on the first embodiment:

[0114] The connecting member includes a welding member (not shown in the figure), which can be melted after reaching the melting point and can connect the heat-dissipating member 106 and the heat-generating member 102 integrally after cooling. Specifically, the welding member is in a solid state at room temperature, and the user can place the welding member into the recess 104. After the heat-dissipating member 106 is sleeved on the heat-generating member 102, the heat-generating member 102 is powered to heat the welding member, so that the welding member is heated and melted. Then, the heat-generating member 102 is powered off, and the temperature of the welding member gradually decreases and cools to a solid state, thereby connecting the heat-dissipating member 106 and the heat-generating member 102 integrally. Specifically, the welding member can be a brazing agent (such as solder paste, etc.).

[0115] Particularly, after the welding member is heated and melted, the liquid welding member can only remain in the recess 104, or part of the welding member can flow to a position outside the recess 104 and connect the heat-dissipating member 106 and the heat-generating member 102 integrally outside the recess 104. However, in either case, the position where the welding member is located does not have a heat-insulating gap, thereby ensuring effective heat conduction and ensuring firm connection between the heat-generating member 102 and the heat-dissipating member 106.

[0116] In addition, the melting point of the connecting member is lower than the melting point of the heat-generating member 102 and also lower than the melting point of the heat-dissipating member 106. In this way, during the process of connecting the heat-generating member 102 and the heat-dissipating member 106, the heating temperature is ensured to reach the melting point of the connecting member and be lower than the melting points of the heat-generating member 102 and the heat-dissipating member 106, so that the heat-generating member 102 and the heat-dissipating member 106 are connected integrally, and it is ensured that deformation of the heat-generating member 102 and the heat-dissipating member 106 does not occur during the heating process.

[0117] It should be noted here that the melting point of the welding member is higher than the heat generation temperature of the heat-generating member 102 during daily use. That is, during the process of connecting the heat-generating member 102 and the heat-dissipating member 106, the power-on voltage of the heat-generating member 102 is greater than the daily working voltage, thereby making the heat generation temperature of the heat-generating member 102 higher than the daily heat generation temperature. In this way, during daily use, the welding member will not be melted again.

[0118] In addition, the heat-generating body 100 proposed in this embodiment also has all the beneficial effects of the heat-generating body 100 proposed in the first embodiment, on the one hand, it can improve the heat transfer effect between the heat-generating member 102 and the heat-dissipating member 106, thereby reducing the energy consumption of the heat-generating member 102, and on the other hand, it can reduce the risk of loosening between the heat-dissipating member 106 and the heat-generating member 102, which will not be discussed in detail here.

[0119] The fourth embodiment of the present application proposes a heat-generating body 100, which is further based on the first embodiment, the second embodiment and the third embodiment:

[0120] As shown in Figure 5 The side wall of the heat-generating member 102 includes a first region (not shown in the figure) and a second region (not shown in the figure), the recess 104 is arranged in the first region, and the recess 104 is not arranged in the second region. In addition, the part of the heat-dissipating member 106 corresponding to the recess 104 is in contact with the connecting member, and the part of the heat-dissipating member 106 corresponding to the second region is in contact with the second region; that is, the first region of the heat-generating member 102 is in contact with the connecting member, and the connecting member is further in contact with the heat-dissipating member 106; the second region of the heat-generating member 102 is directly in contact with the heat-dissipating member 106.

[0121] Specifically, in the process of manufacturing the heat-generating member 102, the liquid connecting member remains in the recess 104, and the connecting member connects the heat-dissipating member 106 and the heat-generating member 102 inside the recess 104.

[0122] In this way, during the operation of the heat-generating body 100, the heat released by the heat-generating body 100 from the first region can be at least conducted to the heat-dissipating member 106 through the connecting member, and the heat released by the heat-generating body 100 from the second region can be at least directly conducted to the heat-dissipating member 106, so that the risk of heat concentration at the position of the connecting member can be effectively reduced, and the risk of the heat-dissipating member 106 falling off can be reduced. Moreover, since the connecting member directly connects the heat-dissipating member 106 and the heat-generating member 102 in the first region, and the heat-generating member 102 is directly connected to the heat-dissipating member 106 in the second region, the heat transfer efficiency between the heat-generating member 102 and the heat-dissipating member 106 is improved, the heat accumulation between the heat-generating member 102 and the heat-dissipating member 106 is avoided, and the heat generation efficiency of the heat-generating body 100 is improved.

[0123] In addition, the heat-generating body 100 provided by the embodiment also has all the beneficial effects of the heat-generating body 100 provided by the first embodiment, which can improve the heat transfer effect between the heat-generating member 102 and the heat-dissipating member 106, thereby reducing the energy consumption of the heat-generating member 102, and can reduce the risk of the heat-dissipating member 106 and the heat-generating member 102 falling off, which will not be discussed in detail here.

[0124] The fifth embodiment of the present application provides a heat-generating body 100, which is further based on the first embodiment, the second embodiment and the third embodiment:

[0125] As shown in Figure 5 The side wall of the heat-generating member 102 includes a first region and a second region, and the recess 104 is arranged in the first region. The second region does not have the above-mentioned recess 104. In addition, the connecting member is located in the first region and the second region, and is connected to the heat-generating member 102 and the heat-dissipating member 106 at the same time.

[0126] Specifically, in the process of manufacturing the heat-generating member 102, part of the liquid connecting member remains in the recess 104, and the other part flows to the outside of the recess 104, so that the connecting member connects the heat-dissipating member 106 and the heat-generating member 102 inside and outside the recess 104.

[0127] In this way, during the operation of the heat-generating body 100, the heat released by the heat-generating body 100 from the first region and the second region can be at least conducted to the heat-dissipating member 106 through the connecting member. Moreover, since the connecting member directly connects the heat-dissipating member 106 and the heat-generating member 102 in the first region and the second region, the heat transfer efficiency between the heat-generating member 102 and the heat-dissipating member 106 is improved, the heat accumulation between the heat-generating member 102 and the heat-dissipating member 106 is avoided, and the heat generation efficiency of the heat-generating body 100 is improved.

[0128] In addition, the heating body 100 provided by the embodiment has all beneficial effects of the heating body 100 provided by the first embodiment, and can improve the heat transfer effect between the heating element 102 and the heat dissipation element 106, thereby reducing the energy consumption of the heating element 102, and can reduce the risk of loosening between the heat dissipation element 106 and the heating element 102, which will not be discussed in detail here.

[0129] The sixth embodiment of the present application provides a heating body 100, which is further based on the first embodiment, the second embodiment, the third embodiment, the fourth embodiment and the fifth embodiment.

[0130] As shown in Figure 5 and Figure 6 , the heat dissipation element 106 includes fins 110 and flanges 112. The fins 110 are provided with mounting holes, and the edges of the mounting holes are provided with flanges 112; the heating element 102 is arranged in the mounting hole, and the flanges 112 are connected with the heating element 102 by the connecting piece. That is, in the heating body 100 provided by the present application, the heat dissipation element 106 is connected with the heating element 102 by the flanges 112, and the heat is dissipated to the surrounding environment by the fins 110 to achieve the effect of heating.

[0131] Specifically, as shown in Figure 5 and Figure 6 , the flanges 112 and the fins 110 are of an integral structure. Specifically, the heat dissipation element 106 can be made of aluminum fins.

[0132] In particular, as shown in Figure 5 and Figure 6 , by providing the flanges 112, on the one hand, the connecting area between the heat dissipation element 106 and the heating element 102 can be ensured, especially the effective connecting area of the connecting piece, and on the other hand, the contact area between the heat dissipation element 106 and the heating element 102 can be ensured, so as to further improve the heat transfer efficiency between the heating element 102 and the heat dissipation element 106.

[0133] Specifically, as shown in Figure 1 , Figure 2 and Figure 3 , the number of fins 110 is multiple, and each fin 110 is provided with a mounting hole and a flange 112. In addition, the heating element 102 is arranged in multiple fins 110 at the same time, so as to improve the heat dissipation area of the heating body 100 by the multiple fins 110, thereby improving the heating efficiency of the heating body 100.

[0134] In addition, the heating body 100 provided in the embodiment has all the beneficial effects of the heating body 100 provided in the first embodiment, and can improve the heat transfer effect between the heating member 102 and the heat dissipation member 106, thereby reducing the energy consumption of the heating member 102, and can reduce the risk of loosening between the heat dissipation member 106 and the heating member 102, which will not be discussed in detail here.

[0135] The seventh embodiment of the present application provides a heating body 100, which is further based on the first embodiment, the second embodiment, the third embodiment, the fourth embodiment, the fifth embodiment and the sixth embodiment, and has:

[0136] As shown in Figure 7 , Figure 8 and Figure 9 , the heating member 102 includes a heating pipe 114, a heating element 116 and an insulating member 118. The recess 104 is arranged on the side wall of the heating pipe 114, and the heat dissipation member 106 is connected with the heating pipe 114 through the connecting member to form an integrated body, the heating element 116 is arranged inside the heating pipe 114 and can be used to release heat when powered on, and the insulating member 118 is filled inside the heating pipe 114, and the heating wire is isolated from the heating pipe 114 through the insulating member 118. In addition, the insulating member 118 is a heat conducting member and can efficiently conduct the heat generated by the heating element 116 to the heating pipe 114.

[0137] Specifically, as shown in Figure 5 and Figure 9 , the heating pipe 114 of the heating member 102 and the flange 112 of the heat dissipation member 106 are connected through the connecting member to form an integrated body.

[0138] Specifically, as shown in Figure 5 and Figure 9 , the recess 104 can be a groove arranged on the side wall of the heating pipe 114.

[0139] In particular, as shown in Figure 5 and Figure 9 , the heating element 116 and the insulating member 118 are arranged inside the heating pipe 114, thereby playing a certain protective role on the heating element 116 and the insulating member 118 through the heating pipe 114. And the heating pipe 114 is connected with the heating pipe 114 through the connecting member to form an integrated body, thereby ensuring the connection firmness of the heating member 102 and the heat dissipation member 106, and improving the heat transfer efficiency between the heating pipe 114 and the heat dissipation member 106, so as to improve the heating efficiency of the heating body 100.

[0140] Further, as shown in Figure 5 and Figure 9As shown in the figure, the insulating member 118 is located at least between the heat generating element 116 and the heat generating tube 114, thereby achieving good insulation effect, and avoiding the occurrence of electric leakage during use of the heat generating body 100. In addition, the insulating member 118 is a heat conducting member, thereby improving the heat transfer efficiency between the heat generating element 116 and the heat generating tube 114, and improving the heat generating efficiency of the heat generating body 100.

[0141] Specifically, as shown in the figure, Figure 5 and Figure 9 The heat generating tube 114 can adopt a stainless steel heat generating tube, and the insulating member 118 can adopt magnesium oxide powder.

[0142] In addition, the heat generating body 100 proposed in the embodiment also has all the beneficial effects of the heat generating body 100 proposed in the first embodiment, which can improve the heat transfer effect between the heat generating element 102 and the heat dissipating element 106, thereby reducing the energy consumption of the heat generating element 102, and on the other hand, can reduce the risk of loosening between the heat dissipating element 106 and the heat generating element 102, which will not be discussed in detail here.

[0143] The eighth embodiment of the present application proposes a heat generating body 100, which is further based on the seventh embodiment,

[0144] As shown in the figure, Figure 9 and Figure 9 The heat generating element 116 is located at the center of the heat generating tube 114 and extends along the axial direction of the heat generating tube 114. In this way, the distance from the heat generating element 116 to the side wall of the heat generating tube 114 is equal, thereby ensuring uniform heating of the heat generating body 100 in the circumferential direction of the heat generating tube 114.

[0145] In this embodiment, further, the heat generating element 116 is a heat generating wire. In addition, the heat generating wire extends in a spiral shape in the axial direction of the heat generating tube 114. In this way, under the condition that the axial dimension of the heat generating tube 114 is constant, the length of the heat generating wire located in the heat generating tube 114 can be increased, the heat generating capacity of the heat generating wire is improved, and the heat generating efficiency of the heat generating body 100 is improved.

[0146] In addition, the heat generating body 100 proposed in the embodiment also has all the beneficial effects of the heat generating body 100 proposed in the first embodiment, which can improve the heat transfer effect between the heat generating element 102 and the heat dissipating element 106, thereby reducing the energy consumption of the heat generating element 102, and on the other hand, can reduce the risk of loosening between the heat dissipating element 106 and the heat generating element 102, which will not be discussed in detail here.

[0147] The ninth embodiment of the present application proposes a heat generating body 100, which is further based on the seventh embodiment and the eighth embodiment,

[0148] As shown in the figure, Figure 9As shown, the first size L1 from the center of the heating element 116 to the side wall of the heating tube 114 and the second size L2 from the center of the heating element 116 to the bottom wall 120 of the recess 104 are optimized, so that the difference between the first size L1 and the second size L2 is less than or equal to 2mm.

[0149] Therefore, as shown, the first size L1 from the center of the heating element 116 to the side wall of the heating tube 114 and the second size L2 from the center of the heating element 116 to the bottom wall 120 of the recess 104 are optimized, so that the difference between the first size L1 and the second size L2 is less than or equal to 2mm. Figure 9

[0150] Thus, as shown, by limiting the difference between the first size L1 and the second size L2, the difference in heat transferred to the bottom wall 120 of the recess 104 and the side wall of the heating tube 114 is within a certain range, thereby ensuring that the temperature difference between the recess 104 and the side wall of the heating tube 114 is within a certain range, avoiding the case of excessive local temperature of the heating element 102, and reducing the possibility of heat concentration in the recess 104, thereby reducing the risk of disconnection of the connecting member and the heat dissipation member 106, while ensuring the thermal efficiency of the heating body 100. Figure 9

[0151] Specifically, the difference between the first size L1 and the second size L2 can be 0.5mm, 1mm, 1.5mm, 2mm, etc., which is not exhaustively listed here, as long as it can avoid the case of excessive local temperature of the heating element 102, it can be realized, and it can be understood by those skilled in the art.

[0152] In addition, the heating body 100 proposed in the embodiment also has all the beneficial effects of the heating body 100 proposed in the first embodiment, which can improve the heat transfer effect between the heating element 102 and the heat dissipation member 106, thereby reducing the energy consumption of the heating element 102, and on the other hand, it can reduce the risk of disconnection between the heat dissipation member 106 and the heating element 102, which will not be discussed in detail here.

[0153] The tenth embodiment of the present application proposes a heating body 100, which is further based on the seventh, eighth and ninth embodiments:

[0154] As shown, the first size L1 from the center of the heating element 116 to the side wall of the heating tube 114 and the second size L2 from the center of the heating element 116 to the bottom wall 120 of the recess 104 are optimized, so that the difference between the first size L1 and the second size L2 is less than or equal to 2mm. Figure 9 ​​As shown, the recessed size of the recess 104 is a third size L3, the center of the heat-generating element 102 to the side wall of the heat-generating tube 114 has a first size L1, and the ratio of the third size L3 to the first size L1 is greater than or equal to 1 / 2 and less than or equal to 2 / 3. In particular, during the operation of the heat-generating body 100, the heat generated by the heat-generating element 116 is conducted to the recess 104 and the side wall of the heat-generating tube 114, respectively. The ratio of the third size L3 to the first size L1 affects the amount of heat conducted to the recess 104 and the temperature difference between the recess 104 and the side wall of the heat-generating tube 114.

[0155] Therefore, as shown, Figure 9 the present application optimizes the first size L1 of the heat-generating element 116 to the side wall of the heat-generating tube 114 and the third size L3 of the recess 104, so that the ratio of the third size L3 to the first size L1 is greater than or equal to 1 / 2 and less than or equal to 2 / 3.

[0156] In this way, as shown, Figure 9 by limiting the ratio of the third size L3 to the first size L1, the difference in heat transferred to the bottom wall 120 of the recess 104 and the side wall of the heat-generating tube 114 is within a certain range, thereby ensuring that the temperature difference between the recess 104 and the side wall of the heat-generating tube 114 is within a certain range, and avoiding the case of excessive local temperature of the heat-generating element 102.

[0157] In particular, as shown, Figure 9 the ratio of the third size L3 to the first size L1 can be 1 / 2, 2 / 3, etc., which is not exhaustively listed here, as long as it can avoid the case of excessive local temperature of the heat-generating element 102, and it can be realized and understood by those skilled in the art.

[0158] In this embodiment, as shown, Figure 11 the recessed size of the recess 104 is a third size L3. The third size L3 is greater than 0 mm and less than or equal to 2 mm. In this way, on the basis of ensuring that the connecting member can be placed, the recessed size of the recess 104 is prevented from being too large, which would cause the heat-generating element 116 to conduct too much heat to the recess 104, resulting in uneven heating of the heat-generating element 102.

[0159] In particular, as shown, Figure 11 the third size L3 can be 0.5 mm, 1 mm, 1.5 mm, 2 mm, etc., which is not exhaustively listed here, as long as it can avoid the case of excessive local temperature of the heat-generating element 102, and it can be realized and understood by those skilled in the art.

[0160] In addition, the heating body 100 provided in the embodiment has all the beneficial effects of the heating body 100 provided in the first embodiment, and can improve the heat transfer effect between the heating element 102 and the heat dissipation element 106, thereby reducing the energy consumption of the heating element 102, and can reduce the risk of loosening between the heat dissipation element 106 and the heating element 102, which will not be discussed in detail here.

[0161] The tenth embodiment of the present application provides a heating body 100, which is further based on the first embodiment, the second embodiment, the third embodiment, the fourth embodiment, the fifth embodiment, the sixth embodiment, the seventh embodiment, the eighth embodiment and the ninth embodiment, and has:

[0162] As shown in the drawings, Figure 11 The recess 104 includes a bottom wall 120, a first side wall 122 and a second side wall 124. The bottom wall 120 of the recess 104 is opposite to the opening of the recess 104, and the first side wall 122 and the second side wall 124 are arranged on the opposite sides of the bottom wall 120 and connected with the bottom wall 120.

[0163] The eleventh embodiment of the present application provides a heating body 100, which is further based on the tenth embodiment, and has:

[0164] As shown in the drawings, Figure 11 In the circumferential direction of the heating element 102, the size L4 of the opening of the recess 104 is greater than or equal to 1mm and less than or equal to 5mm. In this way, in the circumferential direction of the heating element 102, the size of the opening of the recess 104 is appropriate, thereby facilitating the placement of the connecting element in the recess 104 during the manufacturing of the heating body 100. Specifically, the opening of the recess 104 is arranged opposite to the bottom wall 120 of the recess 104.

[0165] In addition, the speed of heat transfer from the heating element 102 to the heat dissipation element 106 through the connecting element is different from the speed of direct heat transfer from the heating element 102 to the heat dissipation element 106, and the connecting element is prone to heat concentration. Therefore, by optimizing the opening of the recess 104, the present application avoids the opening of the recess 104 being too large, reduces the loosening between the connecting element and the heating element 102 or the heat dissipation element 106, and improves the fastening of the connection.

[0166] Specifically, as shown in the drawings, Figure 11 When the connecting element uses a soldering agent such as soldering paste, the soldering agent is filled by a soldering machine. In the circumferential direction of the heating element 102, the size L4 of the opening of the recess 104 is greater than or equal to 1mm and less than or equal to 5mm, thereby facilitating the filling of the connecting element and improving the manufacturing efficiency of the heating body 100.

[0167] Specifically, as shown in the drawings, Figure 11As shown, the size L4 of the opening of the recess 104 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc., which are not exhaustively listed herein, as long as the filling of the connecting piece is facilitated, and can be realized by those skilled in the art.

[0168] In this embodiment, further, as shown in Figure 11 As shown, the size L5 of the bottom wall 120 in the circumferential direction of the heat generating piece 102 is greater than or equal to 1mm and less than or equal to 3mm. In this way, the opening size of the recess 104 in the circumferential direction of the heat generating piece 102 is appropriate, thereby facilitating the placement of the connecting piece in the recess 104 during the manufacture of the heat generating body 100. Specifically, as shown in Figure 11 As shown, the opening of the recess 104 is opposite to the bottom wall 120 of the recess 104.

[0169] Specifically, the size L5 of the bottom wall 120 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc., which are not exhaustively listed herein, as long as the filling of the connecting piece is facilitated, and can be realized by those skilled in the art.

[0170] In addition, the heat generating body 100 proposed in this embodiment also has all the beneficial effects of the heat generating body 100 proposed in the first embodiment, on the one hand, it can improve the heat transfer effect between the heat generating piece 102 and the heat dissipating piece 106, thereby reducing the energy consumption of the heat generating piece 102, on the other hand, it can reduce the risk of loosening between the heat dissipating piece 106 and the heat generating piece 102, which will not be discussed in detail herein.

[0171] The twelfth embodiment of the present application proposes a heat generating body 100, which is further based on the tenth and eleventh embodiments:

[0172] As shown in Figure 11 As shown, a first included angle a is formed between the first side wall 122 and the bottom wall 120. The first included angle a is greater than or equal to 90°. In this way, the present application optimizes the design of the first included angle a, so that it presents an expanded mouth shape, thereby facilitating the filling of the connecting piece into the recess 104 during the manufacture of the heat generating body 100.

[0173] As shown in Figure 11 In this embodiment, further, a second included angle β is formed between the second side wall 124 and the bottom wall 120. The second included angle β is greater than or equal to 90°. In this way, the present application optimizes the design of the second included angle β, so that it presents an expanded mouth shape, thereby facilitating the filling of the connecting piece into the recess 104 during the manufacture of the heat generating body 100.

[0174] As shown in Figure 11As shown, specifically, the first included angle α can be 90°, 95°, 100°, 105°, 110°, 115°, 120°, etc., and is not listed exhaustively here. As long as it facilitates the filling of the connector, it can be achieved, and those skilled in the art can understand this.

[0175] like Figure 11 As shown, specifically, the second included angle β can be 90°, 95°, 100°, 105°, 110°, 115°, 120°, etc., and is not listed exhaustively here. As long as it facilitates the filling of the connector, it can be achieved, and those skilled in the art will understand.

[0176] like Figure 11 As shown, specifically, the first included angle α is equal to the second included angle β.

[0177] In this embodiment, further, as Figure 11 As shown, in the circumferential direction of the heating element 100, the size L4 of the opening is greater than or equal to the size L5 of the bottom wall 120.

[0178] In addition, the heating element 100 proposed in this embodiment also has all the beneficial effects of the heating element 100 proposed in the first embodiment. On the one hand, it can improve the heat transfer effect between the heating element 102 and the heat sink 106, thereby reducing the energy consumption of the heating element 102. On the other hand, it can reduce the risk of the heat sink 106 and the heating element 102 becoming loose. This will not be discussed in detail here.

[0179] Based on any of the above embodiments, the number of recesses 104 can be one. In this case, the recess 104 extends along the axial direction of the heating element 102, and a connector is filled in the recess 104 to connect the heating element and the heat dissipation element 106 into one unit.

[0180] Based on any of the above embodiments, such as Figure 12 As shown, the number of recesses 104 can be at least two. In this case, at least two recesses 104 are evenly distributed along the circumference of the heating element 102, and each recess 104 extends along the axial direction of the heating element 102. This provides multiple connection points between the heating element and the heat sink 106 in the circumferential direction of the heating element 102, thereby improving the connection strength and stability between the heating element and the heat sink 106. Furthermore, since the second dimension L2 of the recess 104 to the heating element 116 is smaller than the first dimension L1 of the heating element 116 to the sidewall of the heating tube 114, the temperature of the recess 104 is relatively high during operation of the heating element 100, thereby improving the uniformity of the heating element 100 during operation.

[0181] Specifically, such as Figure 1As shown, the number of recesses 104 can be one, two, three, four, etc., which are not exhaustively listed here, as long as the heat generation effect of the heat generation body 100 can be ensured, and this can be realized and understood by those skilled in the art.

[0182] The thirteenth embodiment of the present application proposes a warmer (not shown in the figure) comprising the heat generation body 100 according to the first aspect of the present application.

[0183] Therefore, the warmer proposed by the present application has all the beneficial effects of the heat generation body 100 described above, on the one hand, it can improve the heat transfer effect between the heat generation member 102 and the heat dissipation member 106, thereby reducing the energy consumption of the heat generation member 102, on the other hand, it can reduce the risk of loosening between the heat dissipation member 106 and the heat generation member 102, which will not be discussed in detail here.

[0184] Further, the warmer further comprises an air duct structure (not shown in the figure), the air duct structure comprises an air inlet and an air outlet connected in communication, and the heat generation body 100 described above is arranged in the air duct structure. During the operation of the warmer, external air enters the inside of the air duct structure from the air inlet and is discharged from the air outlet after passing through the heat generation body 100, thereby discharging warm air to the environment; in this way, heat exchange can be carried out to achieve the effect of heating.

[0185] Specifically, the warmer proposed by the present application is a warm air blower.

[0186] The fourteenth embodiment of the present application proposes a manufacturing method of a heat generation body, which is used to manufacture the heat generation body according to the first aspect of the present application, as Figure 2 As shown, the manufacturing method comprises:

[0187] Step 1202, filling the connecting member at least in the recess of the heat generation member;

[0188] Step 1204, sleeving the heat dissipation member on the heat generation member;

[0189] Step 1206, energizing the heat generation member so that the connecting member is melted;

[0190] Step 1208, de-energizing the heat generation member so that the connecting member is solidified to connect the heat generation member and the heat dissipation member into one.

[0191] The manufacturing method of the heat generation body proposed in this embodiment can be used to manufacture the heat generation body according to the first aspect of the present application, which has all the beneficial effects of the heat generation body described above; on the one hand, it can improve the heat transfer effect between the heat generation member and the heat dissipation member, thereby reducing the energy consumption of the heat generation member, on the other hand, it can reduce the risk of loosening between the heat dissipation member and the heat generation member, which will not be discussed in detail here.

[0192] Specifically, in the process of manufacturing the heat-generating body, first, the connecting member is filled at least in the recess of the heat-generating member; then, the heat-dissipating member is sleeved on the heat-generating member, and the connecting member is in contact with the heat-generating member and the heat-dissipating member; then, the heat-generating member is powered to make the heat-generating member operate to generate heat, and the connecting member is melted by the heat; then, the heat-generating member is powered to stop generating heat, and the connecting member gradually solidifies and connects the heat-generating member and the heat-dissipating member into one.

[0193] In this way, the heat-generating body manufactured by the application can make the position where the connecting member is located not exist a heat-insulating gap. In this way, at least part of the heat generated by the heat-generating member is conducted to the heat-dissipating member through the connecting member during the operation of the heat-generating body, which improves the heat conduction efficiency from the heat-generating member to the heat-dissipating member, so that the heat is efficiently and quickly conducted to the heat-dissipating member, thereby reducing the energy consumption of the heat-generating body.

[0194] In addition, the heat-generating body manufactured by the application can realize stable connection of the heat-dissipating member and the heat-generating member through the connecting member, and make the heat-generating member and the heat-dissipating member in close contact (which can be direct contact or indirect contact through the connecting member). In this way, during the daily use of the heat-generating body, the firm connection between the heat-dissipating member and the heat-generating member can be ensured, and the situation that the connection between the heat-dissipating member and the heat-generating member is loose can be avoided, thereby ensuring the safe use of the heat-generating body.

[0195] Specifically, the connecting member can be a hot-melt member or a welded member. In addition, the melting point of the connecting member is higher than the heat-generating temperature of the heat-generating member during daily use. That is, during the connection of the heat-generating member and the heat-dissipating member, the power-on voltage of the heat-generating member is greater than the daily working voltage, so that the heat-generating temperature of the heat-generating member is higher than the daily heat-generating temperature. In this way, during daily use, the connecting member will not be melted again. For example, when the connecting member is solder paste, the heat-generating member is powered to heat the solder paste to more than 400℃.

[0196] The fifteenth embodiment of the application provides a manufacturing method of a heat-generating body, which is further based on the fourteenth embodiment and has the following features:

[0197] After the heat-dissipating member is sleeved on the heat-generating member, the application first performs stamping treatment on the flange of the heat-dissipating member, and then powers the heat-generating member. In this way, during the stamping treatment of the flange of the heat-dissipating member, the flange of the heat-dissipating member can be made to fit the heat-generating member as much as possible.

[0198] In this way, during the subsequent heating of the connecting parts, the connecting parts can simultaneously contact the heat sink and the heat source. Even in areas where the connecting parts are not connected, the heat sink and the heat source can still be in contact as much as possible, reducing the possibility of heat insulation gaps between the heat sink and the heat source. This improves the heat transfer efficiency from the heat source to the heat sink, allowing heat to be transferred to the heat sink efficiently and quickly, thereby reducing the energy consumption of the heating element.

[0199] Specifically, the user can manually stamp the flange of the heat sink, or the user can use relevant stamping equipment to stamp the flange of the heat sink.

[0200] A heating element is a heating device installed inside a heater such as a fan heater to heat the cold air drawn into the heater. The warm air heated by the heating element is discharged into the environment from the air outlet of the fan heater, thus achieving heat exchange through circulation to achieve the effect of raising the temperature.

[0201] In related technologies, the heating element is directly inserted into the heat sink, which can easily lead to loosening at the connection between the heating element and the heat sink. Furthermore, the loose fit between the heating element and the heat sink results in significant thermal resistance at the connection point, leading to low thermal conductivity of the heating element. Additionally, the small contact area between the heating element and the heat sink also contributes to low thermal conductivity and high energy consumption.

[0202] like Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, this invention proposes a heating element 100 and its manufacturing method. The heating element 100 includes at least a heating element 102 and a heat dissipation element 106, which are connected as a single unit by a connector. Wherein, as Figure 9 As shown, the heating element 100 includes a heating tube 114, a heating element 116 disposed inside the heating tube 114, and an insulating member 118; as Figure 9 and Figure 11 As shown, the side wall of the heating element 114 has at least one recess 104. The recess 104 is coated with a connector such as solder paste, and the heating element 102 and the heat sink 106 are connected together by the connector.

[0203] Specifically, such as Figure 11 As shown, the recess size of the recess 104 is the third dimension L3, which is less than or equal to 2 mm. This avoids the heating element 116 from being too short from the recess 104, thereby avoiding the risk of the recess 104 overheating during the operation of the heating element 100.

[0204] Specifically, such asFigure 11 As shown, the recess 104 comprises a bottom wall 120, a first side wall 122 and a second side wall 124; as Figure 11 As shown, the first included angle a between the first side wall 122 and the bottom wall 120 is greater than or equal to 90°; in addition, the second included angle β between the second side wall 124 and the bottom wall 120 is greater than or equal to 90°. In this way, it is convenient to fill the connecting member into the recess 104.

[0205] Specifically, as Figure 9 As shown, the size L4 of the opening of the recess 104 in the circumferential direction of the heating element 102 is greater than or equal to 1mm and less than or equal to 5mm; in addition, as Figure 11 As shown, the size L5 of the bottom wall 120 in the circumferential direction of the heating element 102 is greater than or equal to 1mm and less than or equal to 3mm. In this way, it is convenient to fill the connecting member into the recess 104.

[0206] Specifically, as Figure 5 And Figure 6 As shown, the number of recesses 104 can be one or at least two. When the number of recesses 104 can be at least two, the at least two recesses 104 are distributed in the circumferential direction of the heating pipe 114 in a central symmetric manner, which is convenient to keep the heat dissipation temperature uniform around the heating pipe 114.

[0207] Specifically, as ​ And ​ As shown, the heat dissipation element 106 comprises the fin 110 and the flange 112. The mounting hole is provided on the fin 110, and the edge of the mounting hole is provided with the flange 112; the heating element 102 is arranged in the mounting hole, and the flange 112 is connected with the heating element 102 in an integrated manner through the connecting member.

[0208] Specifically, in the process of manufacturing the heating element 102, the connecting member such as solder paste is applied in the recess 104 of the heating pipe 114, and the fin 110 is sequentially sleeved on the heating pipe 114, so that the solder paste uniformly abuts against the flange 112 on the fin 110; then, the flange 112 and the heating pipe 114 are pressed by the stamping equipment (the flange 112 extrudes and wraps the heating pipe 114); then, the heating pipe 114 is powered on, and the solder paste between the heating pipe 114 and the flange 112 is heated and melted by using the heat generated by the heating pipe 114 (the heating temperature needs to reach 400℃); then, the heating pipe 114 is powered off to cool down, and the heating pipe 114 and the fin 110 are welded in an integrated manner.
