DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0037] In addition, if the terms "first", "second" and the like appear, they are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0038] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0039] The following describes in detail, with reference to the accompanying drawings, the specific structure of a heating device 1 provided by this utility model and its corresponding technical effects.

[0040] by Figure 1 For reference, in this embodiment, the first direction is direction A, which can be understood as the height direction of the heating device; the second direction is direction B, which can be understood as the length direction of the heating device; and the third direction is direction C, which can be understood as the width direction of the heating device.

[0041] It should be noted that, with Figure 1 or Figure 3 For reference, the first direction of the heating device 1 can also be understood as the height direction of the heating device 1.

[0042] Please refer to Figures 1-3 The present invention provides a heating device 1 including a mounting frame 100, a heat dissipation strip 200, and a heating element 300. The mounting frame 100 includes a first end plate 210 and a first mounting plate 110 and a second mounting plate 120 arranged at intervals along a first direction of the heating device 1. The heat dissipation strip 200 has a first end 201 and a second end 202 opposite to each other in a second direction. The heat dissipation strip 200 includes heat dissipation units 220 connected sequentially along the second direction. The heat dissipation unit 220 includes a first side portion 221, a second end plate 223, and a second side portion 222 connected sequentially. The first side portion 221 and the second side portion 222 are disposed on both sides of the second end plate 223 along the second direction. For two adjacent heat dissipation units 220, the first side portion 221 of one heat dissipation unit 220 is connected to the second side portion 222 of the other heat dissipation unit 220 through the first end plate 210. The first end plate 210 and the second end plate 223 respectively abut against the first mounting plate 110 and the second mounting plate 120.

[0043] The first vertical extension and the second vertical extension of the first side 221 have different positions in the third direction and have a spacing in the second direction, the third vertical extension and the fourth vertical extension of the second side 222 have different positions in the third direction and have a spacing in the second direction, the first vertical extension, the second vertical extension, the third vertical extension and the fourth vertical extension all extend along the first direction. The heat sheet 300 is arranged on the side of the second mounting plate 120 away from the heat dissipation strip 200, the heat sheet 300 is perpendicular to the first vertical extension, the second vertical extension, the third vertical extension and the fourth vertical extension, and the heat sheet 300 is parallel to the first end plate 210 and the second end plate 223, that is, the heat sheet 300 is in contact with the second mounting plate 120, so that the pressure can be uniformly distributed and transmitted to the heat sheet 300 after the heat dissipation strip 200 is pressed, and the heat transfer efficiency of the heat sheet 300 to the heat dissipation strip 200 is also increased.

[0044] It can be understood that the first vertical extension and the second vertical extension have a spacing in the second direction, and the third vertical extension and the fourth vertical extension have a spacing in the second direction, that is, the first side 221 and the second side 222 are not flat straight plates, for example, the spacing between the first side 221 and the first end 201 in the third direction thereof changes gradually or suddenly, and the spacing between the second side 222 and the first end 201 in the third direction thereof changes gradually or suddenly.

[0045] The thickness direction of the heat sheet 300, the thickness direction of the second mounting plate 120 and the thickness direction of the first mounting plate 110 are parallel to the first direction, the first direction, the second direction and the third direction are perpendicular to each other, and the arrangement direction of the plurality of heat dissipation units 220 is parallel to the second direction.

[0046] It should be noted that in the present embodiment, perpendicular should not be limited to strict perpendicularity, but should be approximately perpendicular.

[0047] Due to the arrangement of the first side 221 and the second side 222, the size of the first end plate 210 and the second end plate 223 in the second direction can be increased, so that the heat dissipation area of the heat dissipation strip 200 can be increased, the heat exchange efficiency can be increased, and the heating efficiency of the heating device 1 can be improved.

[0048] In addition, in the present embodiment, the heat sheet 300 is arranged on the side of the second mounting plate 120 away from the heat dissipation strip 200, and the first side 221 and the second side 222 are arranged, that is, the heat dissipation strip 200, the second mounting plate 120 and the heat sheet 300 are arranged in the first direction of the heating device 1 in sequence, so that the heat dissipation strip 200 can be uniformly stressed.

[0049] In the embodiment, the number of the heat-generating sheets 300 is multiple, and the multiple heat-generating sheets 300 are sequentially arranged on the second mounting plate 120 along the second direction, the projections of the at least two continuous and adjacent second end plates 223 in the first direction fall within the range of the orthographic projection of the same heat-generating sheet 300 in the first direction, the projections of the at least two continuous and adjacent first vertical extension and second vertical extension on the first side in the first direction fall within the range of the orthographic projection of the same heat-generating sheet 300 in the first direction, and the projections of the at least two continuous and adjacent third vertical extension and fourth vertical extension in the first direction fall within the range of the orthographic projection of the same heat-generating sheet 300 in the first direction. Thus, the heat transfer area of each heat-generating sheet 300 to the heat dissipation unit 220 is ensured, and the heat conduction efficiency is increased to increase the heat dissipation efficiency.

[0050] The orthographic projection of each heat-generating sheet 300 in the first direction is opposite to the orthographic projection of the at least two continuous and adjacent second end plates 223 in the first direction, that is, each heat-generating sheet 300 has at least two second end plates 223 above in the first direction.

[0051] In the embodiment, the first direction of the first end plate 210 and the first direction of the second end plate 223 are parallel to the first direction of the first mounting plate 110. Of course, in some other embodiments, the first direction of the first end plate 210 and the first direction of the second end plate 223 can also not be parallel to the first direction of the first mounting plate 110.

[0052] In detail, the heat-generating sheet 300 is bonded to the side of the second mounting plate 120 away from the heat dissipation strip 200, for example, the heat-generating sheet 300 can be bonded to the second mounting plate 120 by high-temperature silicone.

[0053] Optionally, the heat-generating sheet 300 described above can be a ceramic heat-generating sheet 300.

[0054] In the embodiment, each heat-generating sheet 300 has three second end plates 223 above in the first direction, which can improve the heat transfer efficiency of the heat-generating sheet 300 and the heat dissipation strip 200, thereby improving the heat dissipation efficiency of the heat dissipation strip 200.

[0055] It can be understood that the two adjacent first side 221 and second side 222 have a heat dissipation channel 203, the extension direction of the heat dissipation channel 203 is parallel to the heat-generating sheet 300, and the extension length of the heat dissipation channel 203 in the extension direction is greater than the length of the heat-generating sheet 300 in the third direction.

[0056] In addition, the projection of the heat dissipation channel 203 in the first direction falls within the projection range of the heat-generating sheet 300 in the first direction. In this way, the coverage area of the heat dissipation channel on the heat-generating sheet is increased, the heat dissipation efficiency is increased, and the heat conduction efficiency is improved.

[0057] The heat dissipation channel 203 has a variable distance in the third direction from the first end 201 in the second direction, which can also be understood as that the heat dissipation channel 203 has a variable distance in the third direction from the second end 202 in the second direction.

[0058] The heat dissipation channel 203 can be located between the first side 221 and the second side 222 in one heat dissipation unit 220, and also between the first side 221 and the second side 222 formed in the adjacent heat dissipation unit 220. Since the heat dissipation channel 203 has a variable distance in the third direction from the first end 201, the contact area of the first side 221 and the second side 222 with the airflow is also increased, which can improve the heat exchange effect, and since the first side 221 and the second side 222 are arranged, the airflow disturbance effect when the airflow passes through the heat dissipation channel 203 is also increased, which improves the heating efficiency.

[0059] Please refer to Figures 2-3 In this embodiment, the first side 221 includes the first side plate 2211 and the second side plate 2212 arranged in sequence in the third direction thereof, the first side plate 2211 is closer to the first end 201 than the second side plate 2212, the second side 222 includes the third side plate 2221 and the fourth side plate 2222 arranged in sequence in the third direction thereof, the third side plate 2221 is closer to the first end 201 than the fourth side plate 2222, the third side plate 2221 is opposite to the first side plate 2211, and the fourth side plate 2222 is opposite to the second side plate 2212.

[0060] That is, in this embodiment, the first vertical extension is the side of the first side plate 2211 in the second direction, the second vertical extension is the side of the second side plate 2212 in the second direction, the third vertical extension is the side of the third side plate 2221 in the second direction, and the fourth vertical extension is the side of the fourth side plate 2222 in the second direction.

[0061] Further, in this embodiment, the second end plate 223 includes the first sub-plate 2233 and the second sub-plate 2234 connected in sequence in the third direction, the first sub-plate 2233 is closer to the first end 201 than the second sub-plate 2234, the first side plate 2211 and the third side plate 2221 are arranged on the two sides of the first sub-plate 2233 respectively, the second side plate 2212 and the fourth side plate 2222 are arranged on the two sides of the second sub-plate 2234 respectively, the first side plate 2211, the third side plate 2221 and the first sub-plate 2233 jointly form a first sub-channel 224, the second side plate 2212, the fourth side plate 2222 and the second sub-plate 2234 jointly form a second sub-channel 225, and the first sub-channel 224 and the second sub-channel 225 are in communication and at least partially opposite.

[0062] That is, in the present embodiment, the heat dissipation unit 220 has the first sub-channels 224 and the second sub-channels 225 staggered in the third direction.

[0063] Optionally, the second end plate 223 has a dimension in the second direction greater than or equal to a dimension of the first end plate 210 in the second direction.

[0064] In the present embodiment, in order to ensure the area of the second end plate 223 and also improve the support to the first mounting plate 110, the second end plate 223 has a dimension in the second direction equal to a dimension of the first end plate 210 in the second direction.

[0065] Of course, in some other embodiments, the second end plate 223 can also have a dimension in the second direction smaller than a dimension of the first end plate 210 in the second direction.

[0066] Please refer to Figures 4-6 In some other optional embodiments, the second end plate 223 comprises two first wavy edges 2231 spaced apart in the second direction and two first side edges 2232 spaced apart in the third direction, and the first side portion 221 and the second side portion 222 are both wavy plate structures, and the cross section of the first side portion 221 and the cross section of the second side portion 222 are the same as the first wavy edge 2231.

[0067] That is, in the present embodiment, the first vertical extension is a trough or a crest of the first side portion 221 in the third direction, the second vertical extension is a crest or a trough of the first side portion 221 in the third direction, the third vertical extension is a trough or a crest of the second side portion 222 in the third direction, and the fourth vertical extension is a crest or a trough of the second side portion 222 in the third direction.

[0068] In detail, the first end plate 210 comprises two second wavy edges 211 spaced apart in the second direction and two second side edges 212 spaced apart in the third direction, and the cross section of the first side portion 221 and the cross section of the second side portion 222 are the same as the second wavy edge 211, that is, the first end plate 210 and the second end plate 223 have the same shape and size.

[0069] It should be noted that the waveforms of the first wavy edge 2231 and the second wavy edge 211 are approximately sinusoidal.

[0070] In detail, in the present embodiment, the heat dissipation strip 200 is integrally formed by stamping, that is, in the present embodiment, the first side plate 2211, the second side plate 2212, the third side plate 2221, the fourth side plate 2222, the first sub-plate 2233, the second sub-plate 2234 and the first end plate 210 are different parts of the integral structure. Alternatively, the first end plate 210, the second end plate 223, the first side 221 and the second side 222 are different parts of the integral heat dissipation strip 200 to ensure the heat dissipation efficiency of the heat dissipation strip 200.

[0071] Optionally, the corrugated pitch size of the heat dissipation strip is a, 2≤a≤6mm. For example, the corrugated pitch of the heat dissipation strip can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm or 6mm. It can be understood that the corrugated pitch of the heat dissipation strip refers to the distance between two adjacent peaks (or valleys) of the heat dissipation strip in the second direction. The smaller the corrugated pitch, the more the number of corrugations per unit length, the more the surface area increases, and the better the heat dissipation effect. However, too small corrugated pitch will increase air resistance and affect air circulation, thereby reducing heat dissipation efficiency. Therefore, in the present embodiment, the corrugated pitch size is between 2mm and 6mm, which ensures the heat dissipation effect and does not have excessive air resistance.

[0072] Optionally, the thickness of the heat dissipation strip is t, 0.15≤t≤2.8mm, for example, the thickness of the heat dissipation strip can be 0.15mm, 0.16mm, 0.18mm, 0.2mm, 0.22mm, 0.24mm, 0.25mm, 0.26mm, 0.28mm, 0.3mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 2.6mm or 2.8mm.

[0073] Optionally, the distance between the first end plate 210 and the second end plate 223 in the first direction is h, 5≤h≤10mm. It can be understood that the distance between the first end plate 210 and the second end plate 223 in the first direction can affect the heat dissipation surface area of the heat dissipation strip, and between 5mm and 10mm, for example, the height h can be 5mm, 6mm, 7mm, 8mm, 9mm or 10mm. It can ensure that the heat dissipation strip has sufficient heat exchange area to improve the heating efficiency of the heating device 1.

[0074] Optionally, for each heat dissipation unit 220, the first side 221 has a first part closest to the first end 201 in the third direction, and the first side 221 has a second part farthest from the first end 201 in the third direction, and the size of the first part and the second part in the second direction is b, 0.5≤b≤3mm.

[0075] That is to say, in the embodiment, the dislocation size of the first side plate 2211 and the second side plate 2212 in the second direction is b, and it can be understood that at this time, the first part and the second part can be the first side plate 2211 and the second side plate 2212 respectively, or when the second end plate 223 has two first wavy edges 2231 arranged in the second direction and the first side plate 221 is wavy, the first part and the second part can be the peaks and valleys of the first side plate 221 in the third direction respectively, that is, the peaks and valleys of the first side plate 221 in the third direction have a spacing of b in the second direction. Through the above arrangement, the contact area of each heat dissipation unit 220 with air can be improved, thereby improving the heat dissipation efficiency of the heat dissipation strip 200.

[0076] In order to further ensure the heating efficiency of the heating device 1, the second mounting plate 120 is provided with a baffle 130 at both ends in the second direction, and the heat dissipation strip 200 is in abutment with the two baffles 130 respectively on both sides in the second direction. It can be understood that the baffle 130 not only plays a role in fixing the heat dissipation strip 200 in the second direction, but also increases the contact area with the heat dissipation strip 200 to ensure that the heat energy generated by the heat generating sheet 300 is efficiently transmitted to the heat dissipation strip 200.
