[0003] However, the existing heat exchanger has a large heat dissipation surface, and the high-temperature heating devices are generally arranged on both sides of the box. The heat dissipation surface and the corresponding parts of the high-temperature heating devices can play a heat dissipation role, while the heat dissipation surface and the parts that do not correspond to the high-temperature heating devices (i.e., the middle part of the heat dissipation surface) cannot effectively play a heat dissipation role, resulting in the radiator not being effectively utilized.

[0006] A radiator, comprising a mounting plate and a first heat dissipation fin arranged on a side of the mounting plate, wherein the mounting plate is connected to the slotted opening of the box body, and the first heat dissipation fin is located outside the box body;
[0007] A siphon heat dissipation module, comprising a heat pipe and a heat collector connected to the heat pipe, the heat collector being connected to the mounting plate, the heat pipe and the heat collector forming a circulation pipeline, the reflux section of the circulation pipeline being arranged to be inclined downward along the direction of gravity;

[0014] Optionally, the internal fan and the siphon heat dissipation module are arranged at intervals.
[0015] Optionally, an air outlet of the internal fan faces an inner central area of the box.
[0016] Optionally, the box body includes an openable box cover.
[0017] The technical solution of this utility model has the following advantages:
[0018] 1. The heat dissipation device provided by the utility model transfers a part of the heat to the first heat dissipation fin (i.e., the middle part of the heat dissipation surface) which is not corresponding to the high-temperature heating device through the fan inside the box and the heat collecting part, and transfers the heat to the outside under the action of the fan outside the box. Specifically, the heat is first concentrated into the interior of the heat collecting part by the blowing of the fan inside the box, and the heat collecting part absorbs the heat inside the box and heats the internal liquid, thereby forming an evaporation zone. The heat collecting part is connected to the heat pipe on the mounting plate, and the liquid inside the heat collecting part evaporates and then contacts the heat pipe for condensation and reflux, and then the heat collecting part stores the water refluxed from the condensation zone of the heat pipe again, thereby forming a circulation pipeline. The heat pipe and the heat collecting part transfer the absorbed heat to the first heat dissipation fin in the middle part of the heat dissipation surface, and finally the purpose of effective utilization of the radiator can be achieved.
[0019] 2. The heat dissipation device provided by the utility model directly transfers part of the heat to the outside through the external fan of the box and the first heat dissipation fins (i.e. the parts on both sides of the heat dissipation surface) corresponding to the high-temperature heating device. Specifically, the external fan is arranged outside the box, and the air outlet of the external fan faces the first heat dissipation fins of the radiator, which can directly dissipate the heat inside the box to the outside of the box.

The heat dissipation device provided by the utility model has the evaporation section, horizontal section and reflux section of the circulation pipeline connected in sequence, and the liquid in the heat collecting block evaporates to form gas. Since the gas density is small, it rises to the evaporation section, and the gas condenses into liquid through the evaporation section and horizontal section of the heat pipe. Since the reflux section is set in an inclined manner, the liquid flows back to the inside of the heat collecting block, which can circulate and dissipate the heat in the inner center area of the box, effectively improving the heat dissipation efficiency.

[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0041] like Figure 1 As shown, a specific implementation of the heat dissipation device provided in this embodiment includes: a box body 1, a radiator, a siphon heat dissipation module and an internal fan 8. The box body 1 has a notch 2; the radiator has a mounting plate 3 and a first heat dissipation fin 4 arranged on one side of the mounting plate 3, the mounting plate 3 is connected to the notch 2 of the box body 1, and the first heat dissipation fin 4 is located outside the box body 1;
[0042] The siphon heat dissipation module comprises a heat pipe 5 and a heat collector connected to the heat pipe 5, the heat collector is connected to the mounting plate 3, the heat pipe 5 and the heat collector form a circulation pipeline, and the reflux section 14 of the circulation pipeline is arranged to be tilted downward along the gravity direction;
[0043] The internal fan 8 is arranged inside the box 1, and the air outlet of the internal fan 8 faces the heat collecting element;
[0044] The heat dissipation device provided in this embodiment transfers part of the heat to the second heat dissipation fin (i.e., the middle part of the heat dissipation surface) which is not corresponding to the high-temperature heating device through the fan 8 inside the box body 1 and the heat collection part, and transfers the heat to the outside under the action of the fan outside the box body. First, the heat is concentrated inside the heat collection part by the blowing of the internal fan, and the heat collection part absorbs the heat inside the box body 1 and heats the internal liquid, thereby forming an evaporation zone. The heat collection part is connected to the heat pipe 5 on the mounting plate 3, and the liquid inside the heat collection part evaporates and then contacts the heat pipe 5 to condense and reflux, and then the heat collection part stores the water refluxed from the condensation zone of the heat pipe 5 again, thereby forming a circulation pipeline. The heat pipe 5 and the heat collection part transfer the absorbed heat to the first heat dissipation fin 4 on one side of the mounting plate 3, and finally the purpose of effective utilization of the radiator can be achieved.
[0045] like Figure 1 , Figure 3 and Figure 4 As shown, in the heat dissipation device provided in this embodiment, the external fan 9 is arranged outside the box 1, and the air outlet of the external fan 9 faces the first heat dissipation fin 4 of the radiator. In this way, the heat inside the box 1 can be dissipated to the outside of the box 1.
[0046] Of course, the above description is not restrictive, and in some alternative embodiments, the external fan 9 may not be provided or may be provided in plurality.
[0047] like Figure 1 , Figure 5As shown, in the heat dissipation device provided in this embodiment, the heat collecting part includes a heat collecting block 6 and a second heat dissipating fin 7 connected to the heat collecting block 6, the second heat dissipating fin 7 extends toward the interior of the box body 1 in a direction perpendicular to the mounting plate, and the air outlet of the internal fan 8 faces the second heat dissipating fin 7. It should be noted that the second heat dissipating fin 7 has a plurality of fin plates arranged at intervals, and air ducts are formed between any two adjacent fin plates, and the air outlet of the internal fan 8 faces the air ducts to blow the air flow through the plurality of air ducts and transfer the heat to the fin plates. In this arrangement, the internal fan 8 is used to first concentrate the heat inside the box body 1 to the second heat dissipating fin 7, and then the second heat dissipating fin 7 is transferred to the heat collecting block 6, so that an evaporation zone can be formed inside the heat collecting block 6.
[0048] Of course, the above description is not restrictive, and in some alternative embodiments, the air outlet of the internal fan 8 may also be directed toward the second heat dissipating fins 7 and the heat collecting block 6 at the same time.
[0049] like Figure 2 As shown, in the heat dissipation device provided in this embodiment, the mounting plate 3 has a surface groove 11, and the heat pipe 5 and the heat collecting block 6 are embedded in the surface groove 11. In this way, the heat pipe 5 and the heat collecting block 6 can be embedded in the radiator, and the heat can be dissipated from the inside to the outside.
[0050] Of course, the above description is not restrictive, and in some alternative embodiments, the surface groove 11 can be omitted, and the heat pipe 5 and the heat collecting block 6 can be closely connected to the mounting plate 3 .
[0051] like Figure 1 As shown, in the heat dissipation device provided in this embodiment, the siphon heat dissipation module has two groups symmetrically arranged. Such an arrangement can effectively conduct the heat in the central area inside the box 1 to the two ends inside the box 1 at the same time, thereby improving the heat dissipation efficiency.
[0052] Of course, the above description is not restrictive, and in some alternative embodiments, the siphon heat dissipation module may be provided in only one group or more groups.
[0053] like Figure 1 As shown, in the heat dissipation device provided in this embodiment, the heat pipe 5 extends toward the inner center area of the box body 1. Such an arrangement can effectively bring the heat that cannot be dissipated in the inner center area of the box body 1 out to both ends of the box body 1.
[0054] Of course, the above description is not restrictive, and in some alternative embodiments, the heat pipe 5 may extend toward multiple areas inside the box 1 .
[0055] like Figure 3 , Figure 6 As shown, the heat dissipation device provided in this embodiment, when the box is installed in a manner perpendicular to the ground, in the box 1, the circulation pipeline of the siphon heat dissipation module includes: an evaporation section 12 extending upward along the gravity direction, a horizontal section 13 extending toward the inner center area of the box 1, and the reflux section 14, and the evaporation section 12, the horizontal section 13 and the reflux section 14 are connected in sequence. In this way, the liquid evaporates through the heat collecting block 6 to form gas, and due to the small density of the gas, it rises to the evaporation section 12, and the gas passes through the evaporation section 12 and the horizontal section 13 of the heat pipe 5 to condense into liquid. Since the reflux section 14 is arranged in an inclined manner, the liquid flows back to the inside of the heat collecting block 6, which can circulate and dissipate the heat in the inner center area of the box 1, effectively improving the heat dissipation efficiency.
[0056] Of course, the above description is not restrictive, and in some alternative embodiments, the circulation pipeline can be set to various shapes such as arc shape.
[0057] like Figure 1 As shown, in the heat dissipation device provided in this embodiment, the internal fan 8 is spaced apart from the siphon heat dissipation module. Such a configuration can make the heat absorption effect of the second heat dissipation fins 7 better.
[0058] Of course, the above description is not restrictive, and in some alternative embodiments, the internal fan 8 and the siphon heat dissipation module can be arranged in close proximity.
[0059] like Figure 1 As shown, in the heat dissipation device provided in this embodiment, the air outlet of the internal fan 8 faces the inner center area of the box body 1. Such an arrangement can gather the heat at both ends of the box body 1 to the inner center area of the box body 1.
[0060] Of course, the above description is not restrictive, and in some alternative embodiments, the air outlet of the internal fan 8 may be tilted toward the inner center area of the box body 1 .
[0061] like Figure 2 As shown, in the heat dissipation device provided in this embodiment, the box body 1 includes an openable box cover 10. Such a configuration can make the box body 1 more convenient to install, disassemble and maintain.
[0062] Of course, the above description is not restrictive. In some alternative embodiments, the box body 1 may not be provided with an openable box cover 10 or may be provided with a box cover 10 that cannot be opened.
[0063] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present utility model.
