Description

Technical Field

[0001] The present invention relates to the technical field of heating equipment, and in particular to a heat sink and heating equipment. Background Art

[0002] The oil-filled radiator heater is composed of heat sinks, which are connected by oil bags to form upper and lower oil bag passages. The two oil bags of the heat sink itself are connected by multiple oil flow channels to achieve rapid heat transfer from bottom to top.

[0003] When a traditional oil-filled radiator heater is in use, the top of the heater can easily burn the user, posing a safety hazard. Summary of the invention

[0004] Based on this, in order to address the problem that the top of a traditional oil-filled radiator heater can easily scald the user when in use, posing a safety hazard, a heat sink and a heating device are proposed. The heat sink and the heating device can prevent the pressure-bearing part from scalding the user when in use, thereby improving the safety factor of use.

[0005] The specific technical solutions are as follows:

[0006] On the one hand, the present application relates to a heat sink, including a heat sink body, the heat sink body including a pressure-bearing part and a supporting part arranged opposite to each other, the heat sink body also having a circulation channel for circulating a heat-conducting medium, the circulation channel being arranged between the pressure-bearing part and the supporting part, the heat sink body having an anti-scalding zone, the anti-scalding zone being arranged between the circulation channel and the pressure-bearing part, and the anti-scalding zone being formed by an interval between the highest circulation point of the circulation channel and the pressure-bearing part.

[0007] When the above-mentioned heat sink is in use, the supporting part supports the heat sink body, and the heat-conducting medium located in the circulation channel can transfer heat to the heat sink body. Since the highest circulation point of the circulation channel and the pressure-bearing part are spaced apart to form an anti-scalding area, the heat transfer efficiency between the heat-conducting medium in the circulation channel and the pressure-bearing part is relatively low, and thus the temperature of the pressure-bearing part is relatively low. Therefore, when in use, when the user accidentally sits on the pressure-bearing part or places items such as clothes on the pressure-bearing part, the user will not be scalded or the clothes will be damaged, thereby improving the safety factor of use.

[0008] The technical solution is further described below:

[0009] In one of the embodiments, the circulation channel is extended from the support portion to the pressure-bearing portion, and the circulation channel includes a blocking portion arranged opposite to an inlet of the circulation channel, and the blocking portion is used to block the heat-conducting medium from flowing toward the pressure-bearing portion, and the blocking portion is spaced apart from the pressure-bearing portion.

[0010] In one embodiment, the blocking portion is a blocking wall, and the blocking wall is arranged opposite to the inlet of the flow channel.

[0011] In one of the embodiments, the heat dissipation body is further provided with a supply through hole for supplying a heat-conducting medium, and the supply through hole is communicated with the inlet of the circulation channel.

[0012] In one of the embodiments, the heat dissipation body further includes a supply channel, an inner wall of the supply channel is provided with the supply through hole, the supply channel is connected with the circulation channel through the supply through hole, and the supply channel is closer to the supporting portion than the pressure-bearing portion.

[0013] In one embodiment, the heat sink further includes a first protrusion, wherein the first protrusion is fixed to a side wall of the heat sink body, and the first protrusion is spaced apart from the flow channel.

[0014] In one embodiment, the heat sink further includes a second protrusion, the second protrusion is disposed on a side wall of the heat sink body, and the flow channel is disposed in the second protrusion.

[0015] In one embodiment, the heat dissipation body includes a first split body and a second split body, the first split body is provided with a first groove, the second split body is provided with a second groove, the first split body and the second split body are assembled to form the heat dissipation body, and the first groove and the second groove are assembled to form the circulation channel.

[0016] In one of the embodiments, the outer wall of the pressure-bearing part is coated or covered with a heat insulation layer.

[0017] On the other hand, the present application also relates to a heating device, comprising the heat dissipation element described in any of the above embodiments.

[0018] When the above-mentioned heating device is in use, the supporting part supports the heat dissipation body, and the heat-conducting medium located in the circulation channel can transfer heat to the heat dissipation body. Since the highest point of the circulation in the circulation channel and the pressure-bearing part are spaced apart to form an anti-scalding area, the heat transfer efficiency between the heat-conducting medium in the circulation channel and the pressure-bearing part is relatively low, and thus the temperature of the pressure-bearing part is relatively low. Therefore, when in use, when the user accidentally sits on the pressure-bearing part or places items such as clothes on the pressure-bearing part, the user will not be scalded or the clothes will be damaged, thereby improving the safety factor of use.

[0019] The technical solution is further described below:

[0020] In one of the embodiments, the heating device further comprises a heating element, and the heating element is used to heat the heat-conducting medium in the circulation channel. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A traditional oil-filled radiator heater generally includes an upper oil bag flow channel and a lower oil bag flow channel and an oil flow channel connecting the upper oil bag flow channel and the lower oil bag flow channel. The oil flow channel and the upper and lower oil bags contain heat transfer oil. The heating element heats the heat transfer oil in the lower oil bag flow channel. At this time, the heat is transferred along the oil flow channel to the heat transfer oil in the upper oil bag flow channel, thereby making the entire oil-filled radiator heater heat up. At this time, when in use, if the user (especially children) accidentally sits near the pressure-bearing part of the upper oil bag flow channel, they may be easily scalded due to the high temperature there, thereby posing a safety hazard. Based on this, the present invention proposes a heat sink and a heating device. The heat sink and the heating device can prevent the pressure-bearing part from scalding the user when in use, thereby improving the safety factor of use.

[0033] like Figures 1 to 4 As shown, a heating device 10 in one embodiment includes a heat sink 100, which includes a heat sink body 110. The heat sink body 110 includes a pressure-bearing portion 112 and a support portion 114 that are relatively arranged. The heat sink body 110 is also provided with a flow channel 118 for the flow of a heat-conducting medium. The flow channel 118 is arranged between the pressure-bearing portion 112 and the support portion 114. The highest flow point of the flow channel 118 is spaced apart from the pressure-bearing portion 112 to form an anti-scalding area.

[0034] When the heat sink 100 is in use, the support portion 114 supports the heat sink body 110, and the heat-conducting medium in the flow channel 118 can transfer heat to the heat sink body 110 (heat is transferred according to Figures 1 to 4 Since the highest point of the circulation in the circulation channel 118 and the pressure-bearing portion 112 are spaced apart to form an anti-scalding zone, the heat transfer efficiency between the heat-conducting medium in the circulation channel 118 and the pressure-bearing portion 112 is relatively low, and thus the temperature of the pressure-bearing portion 112 is relatively low. Furthermore, since no heat-conducting medium flows in the anti-scalding zone 1102, the heat transfer efficiency in the anti-scalding zone 1102 is relatively reduced. Therefore, when in use, when a user accidentally sits on the pressure-bearing portion 112 or places items such as clothes on the pressure-bearing portion 112, the user will not be scalded or the clothes will be damaged, thereby improving the safety factor of the heating device 10.

[0035] Specifically, the highest point of the circulation channel 118 refers to the highest position to which the heat-conducting medium in the circulation channel 118 can flow in the height direction relative to the heat dissipation body 110. For example, when the circulation channel 118 is extended along the height direction of the heat dissipation body 118, the highest point of the circulation channel 118 is the highest point of the circulation channel 118.

[0036] Specifically, the heat transfer medium may be heat transfer oil.

[0037] Specifically, the heat dissipation body 118 may be made of a thermally conductive material.

[0038] Specifically, the number of the circulation channels 118 may be one or more than two. When the number of the circulation channels 118 is more than two, the circulation channels 118 may be spaced apart or connected to each other through intermediate channels.

[0039] like Figure 1 and Figure 2 As shown, on the basis of the above embodiment, the circulation channel 118 is extended from the support portion 114 to the pressure-bearing portion 112. At this time, the heat-conducting medium can transfer heat from the support portion 114 to the pressure-bearing portion 112. Further, in order to reduce the efficiency of heat transfer to the pressure-bearing portion 112, in this embodiment, the circulation channel 118 includes a blocking portion 1182 arranged opposite to the inlet of the circulation channel 118. The blocking portion 1182 is used to block the heat-conducting medium from flowing to the pressure-bearing portion 112. The blocking portion 1182 is spaced apart from the pressure-bearing portion 112. At this time, the blocking portion 1182 blocks the heat-conducting medium from flowing to the pressure-bearing portion 112. Therefore, the heat-conducting medium cannot flow directly to the pressure-bearing portion 112, thereby reducing the efficiency of heat transfer from the heat-conducting medium to the pressure-bearing portion 112, so that the temperature of the pressure-bearing portion 112 is relatively low. On the basis of this embodiment, the blocking portion 1182 is a blocking wall, which is arranged opposite to the inlet of the circulation channel 118. At this time, the flow of the heat-conducting medium is blocked by the blocking wall.

[0040] Specifically, the blocking portion 1182 can be arranged in the middle of the circulation channel 118 or at the highest circulation point of the circulation channel 118. In this embodiment, the circulation channel 118 is a long strip structure with one end open. At this time, the blocking portion 1182 is the bottom wall of the circulation channel 118, and the bottom wall is the highest circulation point of the circulation channel 118.

[0041] Furthermore, during actual use of the heat sink 100, it is necessary to set a heat-conducting medium in the circulation channel 118. In this embodiment, the heat sink body 110 is also provided with a supply through hole for supplying the heat-conducting medium, and the supply through hole is connected to the inlet of the circulation channel 118. At this time, the heat-conducting medium can be transported to the circulation channel 118 through the supply through hole.

[0042] like Figure 4 As shown, specifically in this embodiment, the heat dissipation body 110 also includes a supply channel 120, and the inner wall of the supply channel 120 is provided with a supply through hole, and the supply channel 120 is connected to the circulation channel 118 through the supply through hole. At this time, the heat-conducting medium in the supply channel 120 is transmitted to the circulation channel 118 through the supply through hole; further, the supply channel 120 is closer to the support part 114 than the pressure-bearing part 112. At this time, the heat-conducting medium is located near the support part 114, and the heat at the pressure-bearing part 112 is relatively low, thereby avoiding scalding the user. Specifically, in this embodiment, the supply channel 120 can be a channel provided in the oil bag structure of the oil-filled radiator heater.

[0043] like Figure 3 and Figure 4 As shown, the heating device 10 includes a plurality of heat sinks 100, each heat sink 100 is provided with a connecting portion, and the connecting portion is provided with a supply channel 120. The heat sinks 100 are connected to each other through the connecting portion, and the supply channels 120 between each heat sink 100 are connected. The connecting portion and the heat sink body 110 can be integrally formed. Specifically, in this embodiment, the connecting portion can be an oil bag structure in an oil radiator heater.

[0044] like Figure 3 As shown, based on any of the above embodiments, the heat sink 100 further includes a first protrusion 116, which is fixed to the side wall of the heat sink body 110, and the first protrusion 116 is spaced apart from the circulation channel 118. In this case, the strength of the heat sink body 110 is enhanced by the first protrusion 116. Specifically, the first protrusion 116 may be a reinforcing rib, and in this embodiment, there are two reinforcing ribs, which are spaced apart, and the circulation channel 118 is disposed between the two reinforcing ribs.

[0045] Specifically, there are many ways to form the flow channel on the heat dissipation body 110. For example, it can be formed by digging inside the complete heat dissipation body 110. Of course, it is also possible to provide a rib structure on the heat dissipation body 110 and dig the flow channel 118 inside the rib structure.

[0046] For example, in one embodiment, the heat sink 100 further includes a second protrusion, which is disposed on the side wall of the heat sink body 110, and the second protrusion is provided with a flow channel 118. Specifically, the second protrusion can be formed by the inner wall of the heat sink body 110 being recessed inward, or can be additionally disposed on the side wall of the heat sink body 110, and the specific formation method can be set as needed.

[0047] For example, in another embodiment, Figure 4As shown, the heat dissipation body 110 includes a first split body 102 and a second split body 104. The first split body 102 is provided with a first groove, and the second split body 104 is provided with a second groove. The first split body 102 and the second split body 104 are assembled to form the heat dissipation body 110. The first groove and the second groove are assembled to form a circulation channel 118. At this time, the first split body 102 and the second split body 104 can be fixedly connected by welding or riveting.

[0048] Furthermore, in order to improve the heat transfer efficiency of the heat-conducting medium in the circulation channel 118, in this embodiment, the width of the circulation channel 118 is H1, and the width of the heat dissipation body is H2, wherein 0<H2≤3H1. At this time, due to the larger cross-sectional area of ​​the circulation channel 118, the time for the heat-conducting medium to transfer heat in the entire circulation channel 118 can be reduced, thereby achieving a rapid heating effect.

[0049] Based on any of the above embodiments, the outer wall of the pressure-bearing part 112 is coated or covered with a heat-insulating layer, so that the risk of scalding the user by the pressure-bearing part 112 is further reduced through the heat-insulating effect of the heat-insulating layer; specifically, the heat-insulating layer can be a ceramic heat-insulating layer.

[0050] like Figure 1 As shown, further, based on any of the above embodiments, the heating device 10 further includes a heating element 200, which is used to heat the heat-conducting medium in the circulation channel 118. Specifically, the heating portion of the heating element 200 can be arranged in the supply channel 120, and the heating element 200 can be a heating element such as a heating wire.

[0051] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
