Referring to FIG. 1 to FIG. 8 together, the heat dissipation monolith 10 of the embodiment of the present invention is used for the electric heating oil 100. The heat dissipation monolith 10 includes a heat dissipation portion 12 to which the body 11 is coupled to the body 11.

The heat sink 12 includes a venting portion 18. The venting portion 18 is provided with a heat dissipation chamber 121. The venting portion 18 projects toward at least one of the two sides 119 of the plane 111 where the body 11 is located with respect to the plane 111 where the body 11 is located. The heat dissipation chamber 121 is connected to the outside atmosphere.

In the heat dissipation monolith 10 of the embodiment of the present invention, since the heat dissipation chamber 121 is connected to the outside atmosphere, the cold air can enter the heat dissipation chamber 121 to exchange heat with the heat dissipation portion 12, thereby promoting heat dissipation and improving. The heat dissipation speed of the heat dissipation portion 12 increases the heat dissipation efficiency of the electric heating oil 100 having the heat dissipation monolith 10 . Moreover, the venting portion 18 protrudes from at least one side of the two sides 119 of the plane 111 of the body 11 with respect to the plane 111 where the body 11 is located, which can increase the heat dissipation area of the venting portion 18, and further improve the electric heating oil having the heat dissipating single piece 10. 100 heat dissipation efficiency.

It should be noted that “the venting portion 18 protrudes from at least one side of the two sides 119 of the plane 111 where the body 11 is located with respect to the plane 111 where the body 11 is located” refers to a position where the venting portion 18 is distributed with respect to the body 11 , that is, It is said that when the plane 111 represents the body 11, the venting portion 18 needs to be in a set state with respect to the plane 111. Moreover, it is because the venting portion 18 protrudes toward at least one side of the two sides 119 of the plane 111 of the body 11 with respect to the plane 111 where the body 11 is located, so that the heat radiated by the heat radiating portion 12 can be guided by the venting portion 18. The lower cover covers a larger space area, thereby enhancing the lateral heat dissipation and longitudinal heat dissipation of the heat dissipation single piece 10.

At the same time, the shape of the venting portion 18 is not specifically limited, and may be set according to actual application conditions. For example, in one example, the vent 18 is disposed about the body 11. Thus, the heat formed at the body 11 can be more uniformly distributed to the periphery under the guiding action of the venting portion 18, so that the heat dissipating single piece 10 is more uniformly radiated outward.

Further, the shape and size of the heat dissipation chamber 121 are not specifically limited, and may be set according to actual application. For example, in one example, the heat dissipation chamber 121 is U-shaped and disposed around the body 11. In this way, more cold air from the outside can enter the heat dissipation chamber 121, and the contact area between the cold air entering the heat dissipation chamber 121 and the heat conducted outwardly from the body 11 is larger, thereby not only improving the cold air and the heat dissipation portion 12 The heat exchange efficiency between the two is effective, and the temperature of the heat dissipation monolith 10 is effectively reduced, and the heat dissipation efficiency of the heat dissipation monolith 10 is ensured.

In the example of the invention, the plane 111 is the reference plane of the body 11. The heat dissipating monolith 10 can be processed with the flat surface 111 as a reference surface for welding. The ventilating portion 18 extends in the longitudinal direction of the heat radiating single piece 10 (shown in the Y-axis direction of FIG. 7). Thus, the heat dissipation area of the heat dissipation portion 12 is large.

In some examples, body 11 is constructed of a thermally conductive material and vent 18 is constructed of a thermally conductive material. The body 11 is welded to the heat dissipation portion 12.

Referring to FIGS. 9-10, the venting portion 18 projects toward the sides 119 of the plane 111 of the body 11 with respect to the plane 111 where the body 11 is located. Thus, since the venting portions 18 are distributed on the two sides 119 of the plane 111 of the body 11, the heat dissipating area of the two sides 119 corresponding to the heat dissipating single piece 10 is increased, so that the heat dissipating single piece 10 is more uniformly radiated outward.

In the example shown in Fig. 10, a portion of the venting portion 18 projects toward one of the two sides 119 of the plane 111 where the body 11 is located, and the other portion of the venting portion 18 is opposite to the sides 119 of the plane 111 where the body 11 is located. The other side is convex. Thus, the heat dissipated by the heat radiating single piece 10 covers a large space area.

Referring to FIG. 11, the venting portion 18 projects toward a side of the two sides 119 of the plane 111 of the body 11 with respect to the plane 111 where the body 11 is located. In the example shown in FIG. 6, the venting portion 18 projects toward the right side of the plane 111 where the body 11 is located with respect to the plane 111 where the body 11 is located.

It should be noted that "right side" refers to a position state in which the heat dissipation single piece 10 is in a normal use state, for example, a position state as shown in FIG.

In one embodiment, the heat sink monolith 10 includes an air outlet 17. The ventilation portion 18 is provided with an air inlet 181. The heat dissipation chamber 121 communicates with the air inlet 17 and the air outlet 17. The air inlet 181 protrudes toward at least one side of the two sides 119 of the plane 111 where the body 11 is located with respect to the plane 111 where the body 11 is located.

In this way, the outside cold air can enter the heat dissipation chamber 121 through the air inlet 181, and can flow out of the heat dissipation chamber 121 from the air outlet 17. At the same time, since the air inlet 181 protrudes toward at least one side of the plane 111 of the body 11, the area of the heat dissipation chamber 121 in contact with the outside air is increased, and the cold air outside is more easily entered into the heat dissipation chamber 121 through the air inlet 181.

It should be noted that the purpose of the air inlet 181 protrudingly is to increase the coverage of the air inlet 181 and increase the amount of cold air entering the air inlet 181. If the venting portion 18 protrudes toward the two sides 119 of the plane 111 of the body 11, the air inlet 181 may protrude toward the two sides 119 of the plane 111 of the body 11, or may be one of the two sides 119 of the plane 111 where the body 11 is located. The side is convex. If the venting portion 18 protrudes toward one of the two sides 119 of the plane 111 of the body 11, the air inlet 181 can protrude toward the convex side of the venting portion 18 of the two sides 119, that is, the air inlet 181 at this time. The protruding direction coincides with the protruding direction of the venting portion 18.

Further, the setting manner of the air outlet 17 can be correspondingly set according to the actual application, and the setting position thereof is not limited. That is to say, the air outlet 17 can be opened at any position on the heat dissipating portion 12, and only needs to be in communication with the heat dissipation chamber 121, and the air outlet of the heat dissipation chamber 121 is not affected.

Referring to FIG. 4 , in one embodiment, the venting portion 18 defines a plurality of air outlet holes 182 . A plurality of air outlet holes 182 form an air outlet 17. The plurality of air outlet holes 182 are linearly spaced apart. The air outlet 17 is closer to the top of the heat dissipation single piece 10 with respect to the air inlet 181.

Thus, since the air outlet 17 is located on the upper side of the air inlet 181, the cold air is cooled by the air inlet 181. After the chamber 121, heat can be caused to flow upward in the heat dissipation chamber 121 at a relatively high speed, thereby improving the heat dissipation efficiency of the heat dissipation monolith 10 as a whole.

It should be noted that the "top" refers to the position state of the heat-dissipating single chip 10 in a normal use state, for example, the position state as shown in FIG.

Referring to FIG. 6, in one embodiment, the heat dissipation chamber 121 protrudes from the plane 111 of the body 11 toward both sides 119 of the plane 111 of the body 11.

Thus, since the heat dissipation chamber 121 protrudes toward the both sides 119 of the plane 111 where the body 11 is located, the space volume of the heat dissipation chamber 121 is increased, so that more cold air enters the heat dissipation chamber 121 and enters the heat dissipation chamber. The contact area between the air in the 121 and the body 11 is large, thereby further ensuring the heat dissipation effect of the heat dissipation portion 12.

In one embodiment, the heat sink 12 includes two fins 13. Two fins 13 are attached to the opposite ends 118 of the body 11 respectively. Each of the fins 13 protrudes toward at least one of the two sides 119 of the plane 111 where the body 11 is located with respect to the plane 111 where the body 11 is located. The venting portion 18 includes two connected venting subsections 183. Each of the fins 13 is formed with a venting portion 183. Each of the ventilation sub-portions 183 is provided with a heat dissipation sub-chamber 184 and an air inlet 181. The two heat sink sub chambers 184 of the two venting subsections 183 are in communication with each other. The two heat sink chambers 184 form part of the heat dissipation chamber 121.

Thus, since each of the heat sinks 13 is distributed on at least one of the two sides 119 of the plane 111 of the body 11, the heat dissipation area of the heat dissipation monolith 10 is increased, so that the heat dissipation speed of the heat dissipation monolith 10 can be improved. At the same time, the cold air enters the heat dissipation sub-chamber 184 from the air inlet 181, so that heat convection can be formed in the heat sink 13, thereby improving the heat dissipation efficiency of each heat sink 13, thereby improving the heat dissipation of the corresponding sides 119 of the body 11. effectiveness.

It should be noted that “each of the fins 13 protrudes from at least one of the two sides 119 of the plane 111 of the body 11 with respect to the plane 111 where the body 11 is located” means that each fin 13 is distributed with respect to the body 11 . The position, that is, the state in which each of the fins 13 needs to be satisfied with respect to the plane 111 when the plane 111 represents the body 11. Moreover, it is precisely because each of the fins 13 protrudes toward at least one side of the two sides 119 of the plane 111 of the body 11 with respect to the plane 111 where the body 11 is located, so that the heat radiated by the heat radiating portion 12 can be made on the heat sink 13. Covering a larger space area under the guiding action, thereby enhancing the lateral heat dissipation and longitudinal heat dissipation of the heat dissipation single piece 10.

Further, the two venting portions 183 of the two fins 13 and the two venting portions 183 of the venting portion 18 refer to the same portion. The structure of the fins 13 and the structure of the venting portion 18 can be set as the case may be. The manner in which the fins 13 project toward the plane 111 is not equivalent to the manner in which the venting portion 18 projects toward the plane 111. There is no necessary connection between the protruding manner of the fins 13 and the protruding manner of the venting portion 18. That is to say, when the venting portion 18 is convex, the portion where the venting portion 18 protrudes is not the venting portion 183. Similarly, when the heat sink 13 is projected, the portion where the heat sink 13 protrudes is not the venting portion 183.

For example, if the venting portion 18 protrudes toward the two sides 119 of the plane 111, the fins 13 may protrude toward the two sides 119 of the plane 111, or may protrude toward one of the two sides 119 of the plane 111, or may not Any side of the plane 111 protrudes. If the venting portion 18 protrudes toward one of the two sides 119 of the plane 111, the fins 13 may protrude toward the both sides 119 of the plane 111, or may protrude toward one of the sides 119 of the plane 111, also It may not protrude to either side of the plane 111.

Preferably, when the venting portion 18 projects toward both sides 119 of the plane 111, each of the fins 13 also simultaneously protrudes toward both sides 111 of the plane 111. At this time, not only the heat dissipation area of each of the heat dissipation fins 13 is large, but also the overall heat dissipation area of the heat dissipation portion 12 of the heat dissipation single sheet 10 is large, so that the heat dissipation single sheet 10 has a high heat dissipation speed.

In one example, each of the fins 13 extends along the longitudinal direction of the heat radiating monolith 10 (shown in the Y-axis direction of FIG. 7) and the width direction (shown in the X-axis direction of FIG. 7). Thus, the heat dissipation area of the heat sink 13 is large.

Referring to FIGS. 12 and 13, each of the fins 13 protrudes from the plane 111 of the body 11 toward both sides 119 of the plane 111 of the body 11. In this way, since the heat dissipation fins 13 are distributed on the two sides 119 of the plane 111 of the body 11, the heat dissipation area of the two sides 119 corresponding to the heat dissipation monolith 10 is increased, so that the heat dissipation monolith 10 is more uniformly radiated outward.

In the example shown in FIG. 12, each of the fins 13 protrudes toward the both sides 119 of the plane 111 where the body 11 is located with respect to the plane 111 where the body 11 is located, and the convex directions of the two fins 13 are opposite. Thus, the heat dissipated by the heat radiating single piece 10 covers a large space area.

In the example shown in FIG. 13, each of the fins 13 protrudes from the plane 111 of the body 11 toward both sides 119 of the plane 111 where the body 11 is located, and each of the fins 13 faces the both sides 119 of the plane 111 where the body 11 is located. The degree of bulging is basically the same. In this way, the heat radiated from the heat dissipation monolith 10 to the two sides 119 is substantially the same, so that the heat dissipation is relatively uniform.

Referring to FIGS. 14-16, each of the fins 13 protrudes from a plane 111 of the body 11 toward a side of the two sides 119 of the plane 111 where the body 11 is located.

In the example shown in FIG. 14, one of the two fins 13 protrudes toward the left side of the body 11, and the other fin 13 protrudes toward the right side of the body 11. Thus, the space in which the two fins 13 are entirely covered is large.

It should be noted that "left side" and "right side" refer to a position state in which the heat dissipation single piece 10 is in a normal use state, for example, a position state as shown in FIG.

In the example shown in FIG. 15, both of the fins 13 are convex toward the left side of the plane 111 where the body 11 is located. In this way, the heat dissipation area on the left side of the heat dissipation monolith 10 is increased.

It should be noted that "left side" refers to a position state in which the heat dissipation single piece 10 is in a normal use state, for example, a position state as shown in FIG.

In the example shown in FIG. 16, both of the fins 13 are convex toward the right side of the plane 111 where the body 11 is located.

In one embodiment, each of the venting sub-portions 183 projects toward the sides 119 of the plane 111 of the body 11 with respect to the plane 111 of the body 11. The heat dissipation sub-chamber 184 protrudes from the plane 111 where the body 11 is located toward both sides 119 of the plane 111 where the body 11 is located.

Thus, since the venting sub-portion 183 and the heat-dissipating sub-chamber 184 protrude toward the two sides 119 of the plane 111 of the body 11, this not only increases the spatial volume of the heat-dissipating sub-chamber 184, but also enters the cooling sub-chamber 184. The air can perform sufficient heat exchange with the fins 13, and the heat dissipation area of each of the fins 13 is increased.

In the example shown in FIG. 4, the heat dissipating portion 12 includes a connecting piece 122 that connects the two fins 13. The tab 122 is attached to the edge of the top end 116 of the body 11. The connecting piece 122 is provided with a communication chamber (not shown) that communicates the two heat dissipation sub-chambers 184. The connecting piece 122 is provided with an air outlet 17. The air outlet 17 communicates with the communication chamber. The communication chamber communicates with the two heat dissipation sub-chambers 184 and together constitutes the heat dissipation chamber 121. Thus, the heat dissipation chamber 121 forms a semi-wrapped structure for the body 11, such that the cold air entering the two heat dissipation sub-chambers 184 of the air inlet 181 first flows upward in the heat dissipation sub-chamber 184, and then forms at the absorption body 11. The heat then merges in the communication chamber and finally can be dissipated from the air outlet 17, thereby achieving the effect that the heat formed by the body 11 sufficiently covers the entire heat dissipation monolith 10.

In one embodiment, the venting subsection 183 is formed with a plurality of protrusions 186. The plurality of convex portions 186 are linearly spaced apart. Each convex portion 186 protrudes toward one of the two sides 119 of the plane 111 where the body 11 is located with respect to the plane 111 where the body 11 is located. Each convex portion 186 is provided with an air inlet hole 187. The plurality of air inlet holes 187 form an air inlet 181.

In this way, the air inlet range of the outside cold air is increased, and each of the ventilation sub-portions 183 has a larger air inlet area, so that more cold air enters each of the heat dissipation sub-chambers 184, thereby facilitating heat generated at the body 11. Dissipated. At the same time, the manner in which the plurality of convex portions 186 are spaced apart increases the mechanical strength of the ventilation sub-portion 183.

In one embodiment, the opening 1871 of each air inlet 187 is disposed downward. In this way, the cold air enters the heat dissipation chamber 121 from the air inlet 181 in a bottom-up flow manner, which facilitates the upward flow of the cold air, thereby increasing the flow speed of the air with heat in the heat dissipation chamber 121.

It should be noted that "downward setting" refers to the positional state of the heat-dissipating single piece 10 in a normal use state, for example, the positional state as shown in FIG.

In one example, the opening 1871 of each air inlet hole 187 faces downward and is inclined toward the outer side of the heat sink 13 with respect to the inner side of the heat sink 13. In this way, the range of the outside air entering the cold air is increased.

It should be noted that "the inner side of the heat sink 13" refers to the side where the heat sink 13 is connected to the body 11,

The "outer side of the heat sink 13" refers to the other side of the heat sink 13 opposite to the side to which the body 11 is connected. The "inside of the heat sink 13" and the "outside of the heat sink 13" are based on the positional state of the heat radiating single chip 10 in the normal use state, for example, the position of the heat radiating single chip 10 as shown in FIG.

In the example shown in FIG. 1, the body 11 includes a heat transfer oil pack 16. The number of the heat transfer oil packs 16 is two, and the two heat transfer oil packs 16 are spaced apart, one of the heat transfer oil packs 16 is disposed on the lower side of the body 11, and the other heat transfer oil pack 16 is disposed on the upper side of the body 11. The heat transfer oil pack 16 on the lower side is provided with a first heating chamber 162. A heating pipe (not shown) for heating is disposed in the first heating chamber 162. The heat transfer oil pack 16 on the upper side is provided with a second heat transfer chamber 163. The heating tube is not disposed in the second heat transfer chamber 163, and is only used for conducting heat. The body 11 defines an oil guiding passage 164 that communicates with the first heating chamber 162 and the second heat conducting chamber 163. Since the heating pipe is disposed in the heat-conducting oil bag 16 located on the lower side, the heat generated by the heating pipe is radiated upward, thereby improving the efficiency of the heat generated by the heating pipe and reducing the heat loss. At the same time, this also reduces the setting of the heating tube while ensuring heat dissipation efficiency.

At the same time, the ventilation sub-portion 183 of the heat sink 13 protrudes toward the two sides 119 of the plane 111 of the body 11 with respect to the plane 111 where the body 11 is located. Each of the venting portions 183 is formed with a plurality of convex portions 186. Each convex portion 186 protrudes toward the two sides 119 of the plane 111 of the body 11 with respect to the plane 111 where the body 11 is located. Each convex portion 186 is provided with an air inlet hole 187. The plurality of air inlet holes 187 of each of the fins 13 are linearly spaced apart. The air outlet 17 is closer to the top of the heat dissipation monolith 10 with respect to the heat transfer oil pack 16 on the upper side. Thus, cold air can enter the heat dissipation chamber 121 from the air inlet 181 located on both sides of the heat transfer oil pack 16, and then can flow upward along the heat dissipation chamber 121 with heat and be discharged from the air outlet 17.

In one embodiment, the heat sink 13 includes a first heat sink fin 14 that extends from an end edge of the body 11. The first heat radiation fin 14 is formed with a ventilation sub-portion 183.

In this way, each of the heat dissipation sub-chambers 184 is closer to the body 11 so as to facilitate the heat generated by the body 11.

In one embodiment, the body 141 of the first heat sink sub-sheet 14 is coupled to the venting sub-portion 183. The heat dissipation sub-chamber 184 penetrates the body 141 of the first heat dissipation sub-sheet 14 and the ventilation sub-portion 183. The body 141 of the first heat dissipation sub-sheet 14 is parallel to the plane 111 where the body 11 is located. As such, the space of the heat dissipation sub-chamber 184 is large. At the same time, the body 141 of the first heat dissipation fin 14 extends outward from the one end of the body 11 to further increase the heat dissipation area of the heat sink 13 .

In one embodiment, the first heat dissipation fins 14 protrude toward the sides 119 of the plane 111 of the body 11 with respect to the plane 111 where the body 11 is located. The bottom end 144 of the first heat dissipation sub-segment 14 is provided with an auxiliary air inlet 188 that communicates with the heat dissipation sub-chamber 184. The auxiliary air inlet 188 is spaced apart from the air inlet 181. The opening of the auxiliary air inlet 188 faces downward. As such, the auxiliary air inlet 188 can increase the air intake range of the corresponding heat dissipation subchamber 184. At the same time, since the opening of the auxiliary air inlet 188 faces downward, it facilitates the upward flow of the cold air.

In one embodiment, the heat sink 13 includes a second heat sink sub-sheet 15 that is coupled to the first heat sink sub-sheet 14. The second heat dissipating sub-sheet 15 protrudes from the plane 111 of the body 11 toward the two sides 119 of the plane 111 where the body 11 is located. The angle b between the second heat sink sub-sheet 15 and the plane 111 where the body 11 is located is greater than 0 degrees and less than 180 degrees.

Thus, the arrangement of the second heat dissipating sub-sheets 15 can further increase the effective heat dissipating area of each of the fins 13 while ensuring that the heat radiated by the heat dissipating portion 12 has a large heat dissipating speed along the two sides 119 of the plane 111 of the body 11 .

In one example, the second heat radiation sub-sheet 15 extends along the longitudinal direction of the heat dissipation monolith 10 (shown in the Y-axis direction of FIG. 7) and the width direction (shown in the X-axis direction of FIG. 7).

Referring to FIG. 17, in one embodiment, the angle b between the second heat dissipating sub-sheet 15 and the plane 111 of the body 11 is greater than or equal to 90 degrees and less than 180 degrees.

Thus, the angle b between the second heat dissipating sub-sheet 15 and the body 11 is relatively large, such that the area of the second heat dissipating sub-sheet 15 protruding toward the two sides 119 with respect to the body 11 is large, and the second heat dissipating sub-sheet 15 A large heat conduction space can be formed between the body 11 and the body 11 so that the heat radiated from the body 11 can be led out along the first heat dissipation sub-sheet 14 and the second heat dissipation sub-sheet 15 in time. At the same time, the second heat dissipating sub-sheet 15 has a certain guiding effect on the heat radiated from the heat dissipating portion 12, so that the heat radiated from the heat dissipating portion 12 can be led out from the first heat dissipating sub-sheet 14 to the second heat dissipating sub-sheet 15, thereby increasing heat. The area of space covered.

In some examples, the angle b between the second heat sink sub-sheet 15 and the body 11 may be 90 degrees, 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees, 170 degrees, or 175. degree. It should be noted that the angle b between the second heat dissipation sub-sheet 15 and the body 11 is not limited to the values listed in the above examples.

In the example shown in FIG. 17, each of the heat sinks 13 includes a second heat sink sub-sheet 15, that is, the heat sink portion 12 includes two second heat sink sub-sheets 15. The two second heat sink sub-sheets 15 are disposed in parallel. The second heat sink sub-sheet 15 is substantially in the form of a sheet. The angle b between each of the second heat dissipating sub-sheets 15 and the plane 111 of the body 11 is 90 degrees. Thus, the two sides 119 of the heat dissipation monolith 10 have a large heat dissipation area, and at the same time, since the angle between the second heat dissipation sub-sheet 15 and the body 11 is moderate, the heat dissipation fins 13 have a better covering effect on the body 11 as a whole. And facilitating the flow of air between the heat sink 13 and the body 11 to form a heat convection effect, the heat dissipation speed of the heat sink 13 is large, and the temperature of the entire heat sink 13 is effectively reduced.

Referring to FIG. 18, an electrothermal oil cell 100 according to an embodiment of the present invention includes the heat dissipation monolith 10 according to any of the above embodiments.

In the electric heating oil 100 of the embodiment of the present invention, since the heat dissipation chamber 121 is connected to the outside atmosphere, such cold space After the gas enters the heat dissipation chamber 121, heat exchange with the heat dissipation portion 12 is performed, thereby promoting heat dissipation, increasing the heat dissipation rate of the heat dissipation portion 12, and improving the heat dissipation efficiency of the electric heating oil 100 having the heat dissipation monolith 10. Moreover, the venting portion 18 protrudes from at least one side of the two sides 119 of the plane 111 of the body 11 with respect to the plane 111 where the body 11 is located, which can increase the heat dissipation area of the venting portion 18, and further improve the electric heating oil having the heat dissipating single piece 10. 100 heat dissipation efficiency.

In one embodiment, the plurality of heat dissipation monoliths 10 are plural. The two heat dissipating portions 12 of the adjacent two heat dissipating single sheets 10 are spaced apart and an air flow passage 20 having a chimney effect is formed between the two heat dissipating portions 12 of the adjacent two heat dissipating single sheets 10.

Thus, the chimney effect airflow passage 20 enhances the thermal convection effect between the adjacent two heat dissipation monoliths 10 such that a portion of the heat between the two heat dissipation monoliths 10 can be dissipated into the air by heat convection. Thereby increasing the overall temperature of the space. At the same time, the strong heat convection effect can improve the overall heat dissipation speed of the electric heating oil 100, and can effectively reduce the overall temperature of the electric heating oil 100, thereby improving the safety and service life of the electric heating oil 100.

It should be noted that the two heat dissipating portions 12 of the adjacent two heat dissipating single sheets 10 form a semi-wrapped structure for the body 11. The width of the gap between the two heat dissipating portions 12 of the adjacent two heat dissipating single sheets 10 may be set as the case may be. For example, in one example, in order to prevent the child's fist from directly contacting the higher temperature portion of the body 11, the width of the gap between the two heat dissipating portions 12 may be correspondingly set to be no larger than the width corresponding to the child's fist.

In the present invention, the first feature "on" or "under" the second feature may include direct contact of the first and second features, and may also include first and second features, unless otherwise specifically defined and defined.
