Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0058] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. The terms used in the following embodiments are only for the purpose of describing the specific embodiments, and are not intended to be limiting to the present application. As used in the specification and the appended claims of the present application, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “one or more,” in the embodiments of the present application, refer to one, two, or more than two; “and / or” describes the associated objects in the conjunctive relationship, which means that there can be three kinds of relationships; for example, A and / or B, which means that A exists alone, A and B exist together, B exists alone, and A, B can be singular or plural. The character “ / ” generally represents an “or” relationship between the associated objects.

[0059] In the present specification, the reference to “one embodiment” or “some embodiments” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Therefore, the statements “in one embodiment,” “in some embodiments,” “in other some embodiments,” “in yet some embodiments,” and the like appearing in various places throughout the specification are not necessarily all referring to the same embodiment, but mean “one or more but not all embodiments” unless otherwise specifically stated. The terms “include,” “contain,” “have,” and their variants mean “including but not limited to,” unless otherwise specifically stated.

[0060] The plurality referred to in the embodiments of the present application means greater than or equal to two. It should be noted that in the description of the embodiments of the present application, the terms “first,” “second,” and the like are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order.

[0061] “Vertical” referred to in the present application is “substantially vertical” in actual operation. “Substantially vertical” can be understood as a vertical with certain errors.

[0062] This application provides a heat dissipation device, a radiator, and electrical equipment to reduce damage caused by a radiator explosion.

[0063] like Figures 1-5 As shown, the heat dissipation device 100 provided in this application embodiment includes: a radiator 10 and a first explosive component 20.

[0064] The radiator 10 has a heat exchange medium channel (not shown in the figure) through which the heat exchange medium flows. It is understood that the heat exchange medium is used to absorb heat from the heating device (not shown in the figure). The heat exchange medium can be solid, liquid, or gas, or it can undergo transformations between liquid and gaseous states, or between solid and liquid states, or between solid and gaseous states, or between solid, liquid, and gaseous states. When the heat exchange medium can undergo transformations between liquid and gaseous states, the radiator 10 can be called a thermosiphon radiator. When the heat exchange medium is liquid, the radiator 10 can be called a water-cooled radiator or other liquid-cooled radiator.

[0065] The first explosive component 20 is disposed on the radiator 10 and is connected to the heat exchange medium channel. It is understood that the first explosive component 20 has a channel communicating with the heat exchange medium channel. Thus, the first explosive component 20 contains the heat exchange medium. When the temperature of the heat exchange medium rises to a set value (the pressure of the heat exchange medium rises to the explosive pressure of the first explosive component 20), the first explosive component 20 explodes. By setting the position of the first explosive component 20, a specific location can be exploded; by setting the direction of the first explosive component 20, a specific direction can be exploded. This allows foreign objects or shock waves generated by the explosion to be moved away from specific equipment or specific areas, thereby reducing damage to personnel at specific equipment or specific areas caused by foreign objects or shock waves generated by the explosion. Therefore, the heat dissipation device 100 can reduce damage caused by the explosion.

[0066] Moreover, by setting the burst pressure of the first bursting component 20, the first bursting component 20 can be burst under the set pressure, which improves the safety and reliability of the heat dissipation device 100.

[0067] It should be noted that a specific area can be an area frequently traversed or frequented by people. A specific device can be a component that is difficult to replace and maintain, or a component with high cost; for example, a specific device can be an electrical device such as a heating element. Of course, a specific area can also be understood as other areas, and a specific device can also be understood as other devices; this application does not limit this interpretation.

[0068] In the heat dissipation device 100, the first explosion component 20 can be welded to the heat sink 10, or the first explosion component 20 is fixed to the heat sink 10 by fasteners, etc. The embodiments of the present application do not limit the setting mode of the first explosion component 20.

[0069] As shown in Figures 1-5 , one end of the first explosion component 20 is fixed to the heat sink 10 and communicates with the heat exchange medium passage. In this way, the installation of the first explosion component 20 can be simplified.

[0070] As shown in Figure 1 , in order to protect the stability of the first explosion component 20, the first explosion component 20 can be fixed to the heat sink 10 and communicate with the heat exchange medium passage at its first position, and the first explosion component 20 is fixed to the heat sink 10 by the mounting seat 40 at its second position. In this way, the connection stability of the first explosion component 20 and the heat sink 10 is improved.

[0071] For the specific structure of the mounting seat 40, it is selected according to the actual situation, and the embodiments of the present application do not limit it.

[0072] In the heat dissipation device 100, the structure, shape and size of the first explosion component 20 are designed according to the actual situation, as long as the first explosion component 20 can be away from the specific equipment or specific area.

[0073] In the heat dissipation device 100, the first explosion component 20 can be a pipe. For example, the first explosion component 20 is a round pipe, a square pipe, a rectangular pipe, a spherical pipe, a semispherical pipe or other shaped pipe, so that the first explosion component 20 and the heat exchange medium passage are communicated.

[0074] It can be understood that one end of the first explosion component 20 is closed and the other end is open, and the end of the first explosion component 20 with the opening communicates with the heat exchange medium passage, which can be understood as: the end of the first explosion component 20 with the opening is connected with a certain component of the heat sink 10.

[0075] For example, as shown in Figure 1 , Figure 3 and Figure 4 , the first explosion component 20 is a straight pipe; as shown in Figure 1 and Figure 2 , the first explosion component 20 is a bent pipe. Among them, the bent pipe can be an L-shaped pipe or an arc-shaped pipe, etc. The embodiments of the present application do not limit it.

[0076] In the embodiments of the present application, in the case that the first explosion component 20 is a straight pipe, one end of the first explosion component 20 in the axial direction can be fixed to the heat sink 10 and communicate with the heat exchange medium passage.

[0077] The first burst component 20 can be a single-layer pipe or a multi-layer pipe. The multi-layer pipe includes at least two nested pipes.

[0078] In actual cases, the first burst component 20 can also be a box or other structure, and is not limited to a pipe, as long as the first burst component 20 has a cavity for containing the heat exchange medium, so that the first burst component 20 is in communication with the heat exchange medium passage.

[0079] The first burst component 20 bursts before the radiator 10, or the first burst component 20 bursts and the radiator 10 does not burst. To achieve this purpose, the burst pressure of the first part 21 of the first burst component 20 can be selected to be less than the burst pressure of the second part 22. In this way, the first part 21 is a weak part, and the first part 21 bursts before the second part 22, or the first part 21 bursts and the second part 22 does not burst, which can further achieve a burst at a specific position and in a specific direction, and can further reduce damage caused by the explosion.

[0080] It should be noted that the first part 21 and the second part 22 of the first burst component 20 are both used to contact the heat exchange medium, and the pressurization speed of the heat exchange medium in the first part 21 is the same as the pressurization speed of the heat exchange medium in the second part 22. The burst pressure of the first part 21 refers to the maximum pressure value borne by the first part 21 when the first part 21 bursts, and the burst pressure of the second part 22 refers to the maximum pressure value borne by the second part 22 when the second part 22 bursts. The sizes of the first part 21 and the second part 22 are selected according to actual conditions, and the embodiments of the present application do not limit this.

[0081] In the first burst component 20, the first part 21 and the second part 22 are distinguished according to the burst pressure, and it does not mean that the first burst component 20 is designed as two components of the first part 21 and the second part 22. It can be understood that the first part 21 and the second part 22 are two separate components, or the first part 21 and the second part 22 are an integral structure, or a part of the first part 21 and a part of the second part 22 are an integral structure, and another part of the first part 21 and another part of the second part 22 are two separate components.

[0082] The first burst component 20 is a pipe, and the flow direction of the heat exchange medium in the first burst component 20 is the axial direction of the first burst component 20, and the radial direction of the first burst component 20 is perpendicular to the axial direction of the first burst component 20.

[0083] For the convenience of production and manufacture, the first portion 21 and the second portion 22 can be distributed along the axial direction of the first blasting component 20. In this case, the first portion 21 and the second portion 22 can be located at two ends of the axial direction of the first blasting component 20 respectively; or, the second portion 22 is two and is distributed along the axial direction of the first blasting component 20, and the first portion 21 is located between the two second portions 22.

[0084] In the case of machining the first blasting component 20 by turning or other processes, the second portion 22 is two and is distributed along the axial direction of the first blasting component 20, and the first portion 21 is located between the two second portions 22. In this way, the first portion 21 can be machined conveniently by fixing at the two second portions 22.

[0085] For the further convenience of machining, the cross section of the first portion 21 and the cross section of the second portion 22 are of the same shape, and the cross section of the first portion 21 and the cross section of the second portion 22 are both perpendicular to the axial direction of the first blasting component 20. Of course, the cross section of the first portion 21 and the cross section of the second portion 22 can be of different shapes.

[0086] The first portion 21 and the second portion 22 in the first blasting component 20 can also be distributed along the circumferential direction of the first blasting component 20.

[0087] In the case that the blasting pressure of the first portion 21 is less than the blasting pressure of the second portion 22, the first blasting component 20 can be a single-layer pipe, which simplifies the production and manufacture of the first blasting component 20. Of course, the first blasting component 20 can also be a multi-layer pipe, which can be understood as at least two pipes sleeved and connected in the radial direction.

[0088] In the case that the first portion 21 and the second portion 22 are distributed along the axial direction of the first blasting component 20 and the first blasting component 20 is a multi-layer pipe, the first portion 21 is a single-layer pipe, and the second portion 22 is a multi-layer pipe; or, the first portion 21 and the second portion 22 are both multi-layer pipes, and the number of layers of the first portion 21 is less than the number of layers of the second portion 22. In this way, the machining of the first portion 21 and the second portion 22 is facilitated, and the blasting pressure of the first portion 21 being less than the blasting pressure of the second portion 22 is also facilitated.

[0089] For example, the first blasting component 20 includes an inner layer pipe and an outer layer pipe, the outer layer pipe is sleeved on the inner layer pipe, and the outer layer pipe is located at both ends of the inner layer pipe, so that the part between the two ends of the inner layer pipe is not sleeved by the outer layer pipe, and the part of the inner layer pipe not sleeved by the outer layer pipe forms the first portion 21, and the part of the inner layer pipe sleeved by the outer layer pipe and the outer layer pipe form the second portion 22.

[0090] To realize that the burst pressure of the first portion 21 in the first burst component 20 is less than the burst pressure of the second portion 22, in a first aspect, the wall thickness of the first portion 21 can be selected to be less than the wall thickness of the second portion 22; in a second aspect, the material strength of the first portion 21 can also be selected to be less than the material strength of the second portion 22; in a third aspect, the first portion 21 can also be provided with a groove; in a fourth aspect, when the first burst component 20 is a pipe, the first portion 21 and the second portion 22 are distributed along the axial direction of the first burst component 20, the cross section of the first portion 21 and the cross section of the second portion 22 are of the same shape, the width of the inner wall of the first portion 21 in the radial direction of the first burst component 20 is greater than the width of the inner wall of the second portion 22 in the radial direction of the first burst component 20, and / or the width of the outer wall of the first portion 21 in the radial direction of the first burst component 20 is less than the width of the outer wall of the second portion 22 in the radial direction of the first burst component 20.

[0091] Based on the above-mentioned first aspect, the second aspect, the third aspect and the fourth aspect, in the embodiments of the present application, there are mainly the following fifteen kinds of choices:

[0092] Firstly, the first aspect can be used to realize that the burst pressure of the first portion 21 in the first burst component 20 is less than the burst pressure of the second portion 22.

[0094] Third, the first part 21 of the first bursting member 20 can have a lower bursting pressure than the second part 22 by the first aspect and the third aspect.

[0109] It should be noted that the "whether the first part 21 has a groove" mentioned in the foregoing includes: the first part 21 has a groove, and the first part 21 has no groove.

[0110] Note that the "distribution direction of the first portion 21 and the second portion 22" mentioned above includes a case where the first portion 21 and the second portion 22 are distributed in the axial direction of the first bursting member 20, a case where the first portion 21 and the second portion 22 are distributed in the circumferential direction of the first bursting member 20, and other distribution directions.

[0111] Note that the "shape of the cross section of the first portion 21 and the second portion 22" mentioned above includes a case where the shape of the cross section of the first portion 21 and the second portion 22 is the same, and a case where the shape of the cross section of the first portion 21 and the second portion 22 is different.

[0112] Note that the "size relationship between the width of the inner wall of the first portion 21 in the radial direction and the width of the inner wall of the second portion 22 in the radial direction" mentioned above includes a case where the width of the inner wall of the first portion 21 in the radial direction is equal to the width of the inner wall of the second portion 22 in the radial direction, a case where the width of the inner wall of the first portion 21 in the radial direction is greater than the width of the inner wall of the second portion 22 in the radial direction, and a case where the width of the inner wall of the first portion 21 in the radial direction is less than the width of the inner wall of the second portion 22 in the radial direction.

[0113] Note that the "size relationship between the width of the outer wall of the first portion 21 in the radial direction and the width of the outer wall of the second portion 22 in the radial direction" mentioned above includes a case where the width of the outer wall of the first portion 21 in the radial direction is equal to the width of the outer wall of the second portion 22 in the radial direction, a case where the width of the outer wall of the first portion 21 in the radial direction is greater than the width of the outer wall of the second portion 22 in the radial direction, and a case where the width of the outer wall of the first portion 21 in the radial direction is less than the width of the outer wall of the second portion 22 in the radial direction.

[0114] In the fourth aspect, in a case where the width of the inner wall of the first portion 21 in the radial direction of the first bursting member 20 is greater than the width of the inner wall of the second portion 22 in the radial direction of the first bursting member 20, there are three options:

[0115] First, the width of the outer wall of the first portion 21 in the radial direction of the first bursting member 20 is equal to the width of the outer wall of the second portion 22 in the radial direction of the first bursting member 20, so that the wall thickness of the first portion 21 is smaller than the wall thickness of the second portion 22, and the bursting pressure of the first portion 21 can be made smaller than the bursting pressure of the second portion 22, and it is convenient to process the outer wall of the first bursting member 20.

[0116] Second, the width of the outer wall of the first portion 21 in the radial direction of the first bursting member 20 is smaller than the width of the outer wall of the second portion 22 in the radial direction of the first bursting member 20, so that the wall thickness of the first portion 21 is smaller than the wall thickness of the second portion 22, and the bursting pressure of the first portion 21 can be made smaller than the bursting pressure of the second portion 22.

[0117] Third, the width of the outer wall of the first portion 21 in the radial direction of the first bursting member 20 is greater than the width of the outer wall of the second portion 22 in the radial direction of the first bursting member 20. By adjusting the difference in the width of the inner wall of the first portion 21 and the second portion 22 in the radial direction, and the difference in the width of the outer wall of the first portion 21 and the second portion 22 in the radial direction, the wall thickness of the first portion 21 can be made smaller than the wall thickness of the second portion 22, so that the bursting pressure of the first portion 21 can be made smaller than the bursting pressure of the second portion 22.

[0118] In the fourth aspect, in the case where the width of the outer wall of the first portion 21 in the radial direction of the first bursting member 20 is smaller than the width of the outer wall of the second portion 22 in the radial direction of the first bursting member 20, there are three options:

[0119] First, the width of the inner wall of the first portion 21 in the radial direction of the first bursting member 20 is equal to the width of the inner wall of the second portion 22 in the radial direction of the first bursting member 20. In this way, the wall thickness of the first portion 21 can be made smaller than the wall thickness of the second portion 22, so that the bursting pressure of the first portion 21 can be made smaller than the bursting pressure of the second portion 22. Moreover, it is convenient to process the inner wall of the first bursting member 20.

[0120] Second, the width of the inner wall of the first portion 21 in the radial direction of the first bursting member 20 is smaller than the width of the inner wall of the second portion 22 in the radial direction of the first bursting member 20. By adjusting the difference in the width of the inner wall of the first portion 21 and the second portion 22 in the radial direction, and the difference in the width of the outer wall of the first portion 21 and the second portion 22 in the radial direction, the wall thickness of the first portion 21 can be made smaller than the wall thickness of the second portion 22, so that the bursting pressure of the first portion 21 can be made smaller than the bursting pressure of the second portion 22.

[0121] Third, the width of the inner wall of the first portion 21 in the radial direction of the first bursting member 20 is greater than the width of the inner wall of the second portion 22 in the radial direction of the first bursting member 20. This has been described above, and will not be described here.

[0122] In the fourth aspect, in the case where the first bursting member 20 is a circular pipe, the first portion 21 and the second portion 22 are both circular pipe segments. The width of the inner wall of the first portion 21 in the radial direction of the first bursting member 20 is the inner diameter of the first portion 21, the width of the outer wall of the first portion 21 in the radial direction of the first bursting member 20 is the outer diameter of the first portion 21, the width of the inner wall of the second portion 22 in the radial direction of the first bursting member 20 is the inner diameter of the second portion 22, and the width of the outer wall of the second portion 22 in the radial direction of the first bursting member 20 is the outer diameter of the second portion 22.

[0123] In the fourth aspect, when the first blasting component 20 is a square tube, the first part 21 and the second part 22 are both square tube segments, the width of the inner wall of the first part 21 in the radial direction of the first blasting component 20 is the inner side length of the first part 21, the width of the outer wall of the first part 21 in the radial direction of the first blasting component 20 is the outer side length of the first part 21, the width of the inner wall of the second part 22 in the radial direction of the first blasting component 20 is the inner side length of the second part 22, and the width of the outer wall of the second part 22 in the radial direction of the first blasting component 20 is the outer side length of the second part 22.

[0124] In actual cases, other parameters of the first part and the second part in the first blasting component 20 can also be selected to be different, and are not limited to the above four aspects.

[0125] In order to realize that the first blasting component 20 explodes before the radiator 10 explodes, or the first blasting component 20 explodes and the radiator 10 does not explode, the blasting pressure of the first blasting component 20 can also be selected to be less than the blasting pressure of the radiator 10. In this way, it is convenient to design the first blasting component 20, and it is also convenient to produce and manufacture the first blasting component 20.

[0126] It should be noted that the blasting pressure of the first blasting component 20 refers to the maximum pressure value borne by the first blasting component 20 when the first blasting component 20 explodes; and the blasting pressure of the radiator 10 refers to the maximum pressure value borne by the radiator 10 when the radiator 10 explodes.

[0127] In the case where the blasting pressure of the first blasting component 20 is less than the blasting pressure of the radiator 10, the first blasting component 20 can distinguish the first part 21 and the second part 22, or can not distinguish the first part 21 and the second part 22.

[0128] In the case where the blasting pressure of the first blasting component 20 is less than the blasting pressure of the radiator 10, the structure, shape and material of the first blasting component 20 are not limited. For example, the following three aspects exist:

[0129] In the first aspect, the first blasting component 20 can be an equal-wall-thickness structure;

[0130] In the second aspect, the materials at different positions in the first blasting component 20 can be the same;

[0131] In the third aspect, the first blasting component 20 has no groove structure.

[0132] The above three aspects can be implemented independently or in any combination, and the embodiments of the present application do not limit this.

[0133] The specific position of the first blasting component 20 will be described below according to the specific structure of the radiator 10.

[0134] For example, as shown in FIG. 1, the first blasting component 20 is arranged on the outer wall of the radiator 10. Figure 1, Figure 2 , Figures 4-7 As shown, the radiator 10 includes: a condensing end 11, and a heating end 12 connected to the condensing end 11 and forming a circulation loop. The circulation loop is a structure of the heat exchange medium channel mentioned above.

[0135] The heating end 12 may or may not have an evaporation function. To effectively improve heat dissipation efficiency and effect, the heating end 12 can be selected to have an evaporation function, which can be understood as the heating end 12 being an evaporation end. In this case, the radiator 10 is a thermosiphon radiator, the condensing end 11 can be called a condenser, and the evaporating end can be called an evaporator.

[0136] The heating end 12 may not have an evaporation function. In this case, the radiator 10 can be a liquid-cooled radiator, such as a water-cooled radiator; or, the radiator 10 can be an air-cooled radiator.

[0137] The first explosive component 20 is disposed in at least one of the condensing end 11 and the heating end 12. For example, the first explosive component 20 is disposed in the condensing end 11, or the first explosive component 20 is disposed in the heating end 12, or at least one first explosive component 20 is disposed in the condensing end 11 and at least one first explosive component 20 is disposed in the heating end 12. For example, as... Figure 1 As shown, a first bursting component 20 is disposed at the condensing end 11, and a first bursting component 20 is disposed at the heating end 12.

[0138] like Figure 1 , Figure 2 , Figures 4-7 As shown, the condenser end 11 includes a condenser tube 111. There can be one or more condenser tubes 111. To facilitate communication with the heating end 12, the condenser end 11 also includes a manifold 112, which is connected to the condenser tube 111. Thus, the manifold 112 collects the flow from the condenser tube 111, facilitating communication with the heating end 12. For example, the manifold 112 is connected to the inlet or outlet of the condenser tube 111; or, there are two manifolds 112, namely a first manifold 112a and a second manifold 112b. The first manifold 112a is connected to the outlet of the condenser tube 111, and the second manifold 112b is connected to the inlet of the condenser tube 111. The first manifold 112a is connected to the inlet of the heating end 12, and the second manifold 112b is connected to the outlet of the heating end 12.

[0139] It should be noted that, in order to facilitate the return of the liquid heat exchange medium in the condenser end 11 to the heating end 12, the outlet of the condenser end 11 is lower than the inlet, and the first manifold 112a is lower than the second manifold 112b.

[0140] Based on the structure of the condensation end 11, the position of the first explosive component 20 can be one of the following three situations.

[0141] In the first embodiment, the condenser end 11 includes at least one condenser tube 111, and the first bursting component 20 is disposed on at least one condenser tube 111. In this case, the bursting pressure of the first portion of the first bursting component 20 is less than the bursting pressure of the second portion; or, the bursting pressure of the first bursting component 20 is less than the bursting pressure of the condenser tube 111.

[0142] The second type includes a condenser end 11 comprising a condenser tube 111 and a manifold 112. A first bursting component 20 is disposed on the condenser tube 111, or on the manifold 112, or at least one first bursting component 20 is disposed on both the condenser tube 111 and the manifold 112; wherein the manifold 112 is either a first manifold 112a or a second manifold 112b. For example, as shown... Figure 4 As shown, a first explosive component 20 is disposed on the first manifold 112a. To facilitate the placement of the first explosive component 20, it can be fixed to the first manifold 112a via a fixing seat 30. This placement method is also applicable to situations where the first explosive component 20 is disposed on other pipe fittings. The specific structure of the fixing seat 30 is selected according to the actual situation; this embodiment does not limit this aspect.

[0143] In the second case, the burst pressure of the first part of the first bursting component 20 is less than the burst pressure of the second part; or, the burst pressure of the first bursting component 20 is less than the burst pressure of the pipe (condenser pipe 111 or manifold 112) where the first bursting component 20 is located.

[0144] Thirdly, the condensing end 11 comprises a condensing pipe 111, a first collecting pipe 112a and a second collecting pipe 112b, the first bursting component 20 is arranged in the condensing pipe 111, or the first bursting component 20 is arranged in the first collecting pipe 112a, or the first bursting component 20 is arranged in the second collecting pipe 112b, or at least one first bursting component 20 is arranged in the condensing pipe 111 and at least one first bursting component 20 is arranged in the first collecting pipe 112a, or at least one first bursting component 20 is arranged in the condensing pipe 111 and at least one first bursting component 20 is arranged in the second collecting pipe 112b, or at least one first bursting component 20 is arranged in the first collecting pipe 112a and at least one first bursting component 20 is arranged in the second collecting pipe 112b, or at least one first bursting component 20 is arranged in the condensing pipe 111 and at least one first bursting component 20 is arranged in the first collecting pipe 112a and at least one first bursting component 20 is arranged in the second collecting pipe 112b. In this case, the bursting pressure of the first part of the first bursting component 20 is less than that of the second part; or the bursting pressure of the first bursting component 20 is less than that of the pipe (the condensing pipe 111, the first collecting pipe 112a or the second collecting pipe 112b) where the first bursting component 20 is arranged.

[0145] In the heat sink 10, the heating end 12 can be a heating plate or other structure.

[0146] In the heat sink 10, one side of the heating end 12 is used for mounting a heat generating device (not shown in the figure). In the case where the first bursting component 20 is arranged in the heating end 12, the first bursting component 20 is arranged on the side of the heating end 12 away from the heat generating device. For example, as shown in Figure 4 the right side of the heating end 12 is used for mounting the heat generating device, and the left side of the heating end 12 is provided with the first bursting component 20. In this way, the damage to the heat generating device caused by the explosion can be reduced. Of course, the first bursting component 20 can also be arranged at other positions of the heating end 12, for example, the first bursting component 20 and the heat generating device are arranged on the same side of the heating end 12, and the embodiments of the present application do not limit this.

[0147] In the heat sink 10, the heating end 12 and the condensing end 11 form a circulating loop in various ways. For example, as shown in Figure 1 , Figure 2 and Figure 4 the heat sink 10 further comprises a first connecting pipe 13 and a second connecting pipe 14, the first connecting pipe 13 connects the outlet of the condensing end 11 and the inlet of the heating end 12, and the second connecting pipe 14 connects the inlet of the condensing end 11 and the outlet of the heating end 12.

[0148] It should be noted that when the condenser end 11 includes a first manifold 112a and a second manifold 112b, the first connecting pipe 13 is connected to the first manifold 112a, and the second connecting pipe 14 is connected to the second manifold 112b. The first connecting pipe 13 is a component of the connecting pipe assembly, and the second connecting pipe 14 is a component of the connecting pipe assembly.

[0149] With the structure of the radiator 10 described above, the first bursting component 20 is disposed at the condenser end 11; or, the first bursting component 20 is disposed at the heating end 12; or, the first bursting component 20 is disposed at the first connecting pipe 13; or, the first bursting component 20 is disposed at the second connecting pipe 14; or, the first bursting component 20 is disposed at at least two of the condenser end 11, the heating end 12, the first connecting pipe 13, and the second connecting pipe 14. In this case, the bursting pressure of the first part of the first bursting component 20 is less than the bursting pressure of the second part; or, the bursting pressure of the first bursting component 20 is less than the bursting pressure of the component in which the first bursting component 20 is located (condenser end 11, heating end 12, first connecting pipe 13, or second connecting pipe 14).

[0150] like Figure 5 As shown, the condenser end 11 can be connected to the heating end 12, and the heat exchange medium channel of the condenser end 11 and the heat exchange medium channel of the heating end 12 are directly connected. This eliminates the need for a first connecting pipe 13 and a second connecting pipe 14. In this case, the first bursting component 20 is located at the condenser end 11; or, the first bursting component 20 is located at the heating end 12; or, at least one first bursting component 20 is located at the condenser end 11 and at least one first bursting component 20 is located at the heating end 12. Wherein, the bursting pressure of the first part of the first bursting component 20 is less than the bursting pressure of the second part; or, the bursting pressure of the first bursting component 20 is less than the bursting pressure of the component (condenser end 11 or heating end 12) in which the first bursting component 20 is located.

[0151] like Figure 5 As shown, the condenser end 11 can be connected to the heating end 12, and the gas passage of the condenser end 11 and the heat exchange medium passage of the heating end 12 are directly connected; the liquid passage of the condenser end 11 is connected to the heat exchange medium passage of the heating end 12 through the first connecting pipe 13. Thus, there is no need to provide a second connecting pipe 14, and the connecting pipe assembly includes the first connecting pipe 13. In this case, the first bursting component 20 is located at the condenser end 11; or, as... Figure 5As shown, the first burst component 20 is arranged at the heating end 12; alternatively, the first burst component 20 is arranged at the first connecting pipe 13; alternatively, the first burst component 20 is arranged at at least two of the condensing end 11, the heating end 12 and the first connecting pipe 13. In the first burst component 20, the burst pressure of the first portion is less than that of the second portion; alternatively, the burst pressure of the first burst component 20 is less than that of the component (the condensing end 11, the heating end 12 or the first connecting pipe 13) where the first burst component 20 is arranged.

[0152] It is to be noted that the gas passage and the liquid passage of the condensing end 11 are both part of the heat exchange medium passage of the condensing end 11. The gas and the liquid in the condensing end 11 are both heat exchange medium.

[0153] In actual cases, the condensing end 11 can also be connected to the heating end 12, and the gas passage of the condensing end 11 directly communicates with the heat exchange medium passage of the heating end 12 through the second connecting pipe 14; the liquid passage of the condensing end 11 directly communicates with the heat exchange medium passage of the heating end 12. In this way, the first connecting pipe 13 is not needed, and the connecting pipe assembly includes the second connecting pipe 14. In this case, the first burst component 20 is arranged at the condensing end 11; alternatively, the first burst component 20 is arranged at the heating end 12; alternatively, the first burst component 20 is arranged at the second connecting pipe 14; alternatively, the first burst component 20 is arranged at at least two of the condensing end 11, the heating end 12 and the second connecting pipe 14. In the first burst component 20, the burst pressure of the first portion is less than that of the second portion; alternatively, the burst pressure of the first burst component 20 is less than that of the component (the condensing end 11, the heating end 12 or the second connecting pipe 14) where the first burst component 20 is arranged.

[0154] According to the structure of the heat sink 10 described above, two specific structures of the heat dissipation device 100 are described below in combination with Figure 1 and Figure 2 .

[0155] The first structure, as shown in Figure 1 , the heat dissipation device 100 includes the heat sink 10 and the first burst component 20. The heat sink 10 includes the condensing end 11, the heating end 12, the first connecting pipe 13 and the second connecting pipe 14, the first connecting pipe 13 communicates the outlet of the condensing end 11 with the inlet of the heating end 12, and the second connecting pipe 14 communicates the inlet of the condensing end 11 with the outlet of the heating end 12. The condensing end 11 includes the first manifold 112a, the condensing pipe 111 and the second manifold 112b, the first connecting pipe 13 communicates with the first manifold 112a, and the second connecting pipe 14 communicates with the second manifold 112b. The first burst component 20 is two, one of the first burst components 20 is arranged at the first manifold 112a, and the other of the first burst components 20 is arranged at the heating end 12.

[0156] In the above structure, the first manifold 112a is used to collect the heat exchange medium in each condenser tube 111, realizing the convergence of the heat exchange medium in all condenser tubes 111. This makes the pressure of the heat exchange medium in the first manifold 112a larger than the pressure of the heat exchange medium at other locations on the condenser end 11, resulting in a larger pressure of the heat exchange medium in the first bursting component 20 connected to the first manifold 112a. This allows the first bursting component 20 to burst in a timely manner, improving safety and reliability.

[0157] In the above structure, the pressure of the heat exchange medium in the heating end 12 is more likely to exceed the set value, making it easier for the first bursting component 20 connected to the heating end 12 to burst in a timely manner, thus improving safety and reliability.

[0158] The two first explosive components 20 can be located on the same side of the heating end 12 or on different sides of the heating end 12. The relative positions of the two first explosive components 20 can be selected according to the actual situation, and this application embodiment does not limit this.

[0159] Figure 1 The number of first explosive components 20 in the heat dissipation device 100 shown may be increased, and the first explosive components 20 may be added in other positions. This application embodiment does not limit this.

[0160] The second structure, such as Figure 2 As shown, the heat dissipation device 100 includes a radiator 10 and a first bursting component 20. The radiator 10 includes a condensing end 11, a heating end 12, and a first connecting pipe 13, wherein there is one heating end 12 and two condensing ends 11; one condensing end 11 and the heating end 12 are arranged at an angle relative to each other and are directly connected; the outlet of the other condensing end 11 is connected to the inlet of the heating end 12 through the first connecting pipe 13, and the inlet of the condensing end 11 and the outlet of the heating end 12 are directly connected. The first bursting component 20 is disposed on the heating end 12.

[0161] In the above structure, the pressure of the heat exchange medium in the heating end 12 is more likely to exceed the set value, making it easier for the first bursting component 20 connected to the heating end 12 to burst in a timely manner, thus improving safety and reliability.

[0162] The first explosive component 20 may be located on the same side of the two condensing ends 11 or between the two condensing ends 11.

[0163] The first bursting component 20 and the condensing end 11 can be located on the same side of the heating end 12 or on different sides of the heating end 12.

[0164] The first explosive component 20 can be one or more, and this application embodiment does not limit this.

[0165] Figure 2The first blasting component 20 can also be added at other positions in the heat dissipation device 100. The number of condensing ends 11 can also be increased or decreased, which is not limited in the embodiments of the present application.

[0166] As shown in FIG. 1, the heat dissipation device 100 includes a heat dissipation component 10 and a condensing end 11. The heat dissipation component 10 includes a first blasting component 20. Figures 3-5 As shown in FIG. 1, in order to facilitate injection of the heat exchange medium into the heat exchange medium channel, the heat dissipation component 10 has a flushing pipe 15 for flushing the heat exchange medium. It should be noted that the channel of the flushing pipe 15 is part of the heat exchange medium channel. In this case, the first blasting component 20 is arranged in the flushing pipe 15, or the first blasting component 20 is arranged in other components of the heat dissipation component 10, or at least one first blasting component 20 is arranged in the flushing pipe 15 and at least one first blasting component 20 is arranged in other components of the heat dissipation component 10.

[0167] Since the flushing pipe 15 has a certain length, the first blasting component 20 arranged in the flushing pipe 15 can further move away from other parts of the heat dissipation component 10, and the damage caused by the explosion can be further reduced.

[0168] The flushing pipe 15 can be a round pipe, a square pipe, a rectangular pipe, or other shaped pipes.

[0169] In the case where the first blasting component 20 is arranged in the flushing pipe 15, the blasting pressure of the first part of the first blasting component 20 is less than that of the second part; or the blasting pressure of the first blasting component 20 is less than that of the flushing pipe 15. For the first part and the second part of the first blasting component 20, please refer to the foregoing description.

[0170] As described above, the first blasting component 20 can be a pipe. In order to achieve that the blasting pressure of the first blasting component 20 is less than that of the flushing pipe 15, the specific way of achieving this can refer to the specific way of achieving that the blasting pressure of the first part is less than that of the second part, which will not be described here.

[0171] As shown in FIG. 1, in the axial direction of the flushing pipe 15, the first blasting component 20 is arranged at one end of the flushing pipe 15. As shown in FIG. 2, the first blasting component 20 is arranged on the circumferential side wall of the flushing pipe 15. Figure 3 and Figure 4 As shown in FIG. 1, in the axial direction of the flushing pipe 15, the first blasting component 20 is arranged at one end of the flushing pipe 15. As shown in FIG. 2, the first blasting component 20 is arranged on the circumferential side wall of the flushing pipe 15. Figure 5

[0172] As described above, the heat dissipation component 10 includes the condensing end 11 and the heating end 12. Therefore, the flushing pipe 15 can be arranged in the heating end 12 or the condensing end 11. Alternatively, there are at least two flushing pipes 15, at least one flushing pipe 15 is arranged in the heating end 12, and at least one flushing pipe 15 is arranged in the condensing end 11.

[0173] ​As described above, the heat sink 10 includes the condensing end 11, the heating end 12 and the connecting pipe assembly, the connecting pipe assembly includes at least one of the first connecting pipe 13 and the second connecting pipe 14, and the injection pipe 15 is arranged in at least one of the condensing end 11, the heating end 12 and the connecting pipe assembly. For example, the injection pipe 15 can be arranged in the condensing end 11, the heating end 12, the first connecting pipe 13 or the second connecting pipe 14.

[0174] As described above, the heat sink 10 includes the condensing end 11, the heating end 12 and the connecting pipe assembly, the connecting pipe assembly includes at least one of the first connecting pipe 13 and the second connecting pipe 14, and the injection pipe 15 is arranged in at least one of the condensing end 11, the heating end 12 and the connecting pipe assembly. For example, the injection pipe 15 can be arranged in the condensing end 11, the heating end 12, the first connecting pipe 13 or the second connecting pipe 14. Figures 3-5 As shown, the injection pipe 15 is arranged in the second collecting pipe 112b, and since the second collecting pipe 112b is higher than the first collecting pipe 112a, the injection of the heat exchange medium is facilitated.

[0175] In the embodiments of the present application, the heat sink 10 can have the structure mentioned above or other structures. As shown in the drawings, Figure 6 In some embodiments, the components of the heat sink 10 forming the heat exchange medium channels are channel components 101, and part of the channel components 101 are the second burst components 16. It can be understood that the number of the second burst components 16 is less than the number of all the channel components 101.

[0176] It should be noted that the second burst components 16 burst before the other channel components 101, or the second burst components 16 burst and the other channel components 101 do not burst. The burst pressure of the second burst components 16 can be greater than, less than or equal to the burst pressure of the first burst components 20. The burst pressure of the second burst components 16 refers to the maximum pressure value that the second burst components 16 bear when they burst.

[0177] According to the above description of the heat sink 10, it can be understood that the condensing end 11, the heating end 12, the first connecting pipe 13, the second connecting pipe 14 and the injection pipe 15 can all be understood as channel components 101, and the condensing pipe 111 and the collecting pipe 112 in the condensing end 11 can also be understood as channel components 101.

[0178] In the heat sink 10, in the case where the temperature of the heat exchange medium is raised to a set value (the pressure of the heat exchange medium is raised to the burst pressure of the second burst member 16), the second burst member 16 is burst, the burst at a specified position can be achieved by setting the position of the second burst member 16, the burst at a specified direction can be achieved by setting the direction of the second burst member 16, and the foreign matter or the shock wave generated by the burst can be made to be far away from the specific equipment or the specific area, so that the damage to the specific equipment or the person at the specific area caused by the foreign matter or the shock wave generated by the burst can be reduced, and further, the damage caused by the burst can be reduced.

[0179] Further, by setting the burst pressure of the second burst member 16, the burst of the second burst member 16 at a set pressure can be achieved, and the safety and reliability of the heat sink 10 can be improved.

[0180] Based on the above technical effects, the heat sink 10 can be applied alone without the first burst member 20.

[0181] In order to achieve the purpose that the second burst member 16 is burst before the other passage members 101, or the second burst member 16 is burst and the other passage members 101 are not burst, the burst pressure of the second burst member 16 can be selected to be less than the burst pressure of the passage member 101 in which the second burst member 16 is located. In this way, by designing the position of the second burst member 16, the burst at a specified position and a specified direction can be achieved.

[0182] In order to achieve the purpose that the second burst member 16 is burst before the other passage members 101, or the second burst member 16 is burst and the other passage members 101 are not burst, the burst pressure of the third portion 161 of the second burst member 16 can be selected to be less than the burst pressure of the fourth portion 162, wherein the third portion 161 and the fourth portion 162 are both used to form the heat exchange medium passage. In this way, by designing the position of the second burst member 16 and the position of the third portion 161, the burst position and the burst direction can be further set, so that the damage caused by the burst can be further reduced.

[0183] It should be noted that the distribution of the third portion 161 and the fourth portion 162 of the second burst member 16 can refer to the distribution of the first portion 21 and the second portion 22 of the first burst member 20, which will not be described here.

[0184] As described above, the heat sink 10 includes the condensing end 11 and the heating end 12, and the condensing end 11 is the second burst member 16, or the heating end 12 is the second burst member 16, or the condensing end 11 and the heating end 12 are both the second burst member 16.

[0185] As described above, the heat sink 10 includes the condensing end 11, the heating end 12 and the connecting pipe assembly, the connecting pipe assembly includes at least one of the first connecting pipe 13 and the second connecting pipe 14, at least one of the condensing end 11, the heating end 12 and the connecting pipe assembly is the second burst component 16. For example, at least one of the condensing end 11, the heating end 12, the first connecting pipe 13 and the second connecting pipe 14 is the second burst component 16.

[0186] As described above, the heat sink 10 includes the condensing end 11, the heating end 12 and the connecting pipe assembly, the connecting pipe assembly includes at least one of the first connecting pipe 13 and the second connecting pipe 14, at least one of the condensing end 11, the heating end 12 and the connecting pipe assembly is the second burst component 16. For example, at least one of the condensing end 11, the heating end 12, the first connecting pipe 13 and the second connecting pipe 14 is the second burst component 16.

[0187] As described above, the condensing end 11 includes at least one condensing pipe 111, in the case that the condensing end 11 is the second burst component 16, at least one condensing pipe 111 can be selected as the second burst component 16. In this way, by designing the condensing pipe 111, the condensing pipe 111 can be the second burst component 16, which simplifies the modification of the heat sink 10 itself and reduces the impact on the cost of the heat sink 10. Figure 7 Figure 8 As described above, the condensing end 11 includes at least one condensing pipe 111, in the case that the condensing end 11 is the second burst component 16, at least one condensing pipe 111 can be selected as the second burst component 16. In this way, by designing the condensing pipe 111, the condensing pipe 111 can be the second burst component 16, which simplifies the modification of the heat sink 10 itself and reduces the impact on the cost of the heat sink 10.

[0188] In order to facilitate the second condensing pipe 111b to have a burst pressure less than the first condensing pipe 111a, on the one hand, the length of the second condensing pipe 111b in a certain direction can be greater than the length of the first condensing pipe 111a in the certain direction, and the certain direction is perpendicular to the flow direction of the condensing pipe 111.

[0189] On the other hand, the flow area of the second condensing pipe 111b can be greater than the flow area of the first condensing pipe 111a.

[0190] On the other hand, the wall thickness of the second condensing pipe 111b can be less than the wall thickness of the first condensing pipe 111a.

[0191] On the other hand, the material strength of the second condensing pipe 111b can be less than the material strength of the first condensing pipe 111a.

[0192] The above four aspects can be implemented alone or in combination, and the embodiments of the present application do not limit this.

[0193] For the type of condensing pipe 111, it can be selected according to actual conditions. For example, the condensing pipe 111 can be a straight pipe.​Figure 8 As shown, to improve the heat exchange efficiency, the condensing pipe 111 can be selected as a micro-channel flat tube. It can be understood that the first condensing pipe 111a and the second condensing pipe 111b are both micro-channel flat tubes, and the length direction of the condensing pipe 111 is the flow direction of the condensing pipe 111.

[0194] In the case of the condensing pipe 111 being a micro-channel flat tube, to facilitate the implementation of the aforementioned: the length of the second condensing pipe 111b in the set direction is greater than the length of the first condensing pipe 111a in the set direction, the height of the second condensing pipe 111b can be selected to be greater than the height of the first condensing pipe 111a, and the height of the condensing pipe 111 is perpendicular to the length direction of the condensing pipe 111; and / or, the width of the second condensing pipe 111b can be selected to be greater than the width of the first condensing pipe 111a, and the width of the condensing pipe 111 is perpendicular to the length direction of the condensing pipe.

[0195] In the case of the condensing pipe 111 being a micro-channel flat tube, to facilitate the implementation of the aforementioned: the channel flow area of the second condensing pipe 111b is greater than the channel flow area of the first condensing pipe 111a, as shown, Figure 8 the cross-sectional area of the flat tube hole 1111 of the second condensing pipe 111b can be selected to be greater than the cross-sectional area of the flat tube hole 1111 of the first condensing pipe 111a, and the number of the flat tube holes 1111 of the second condensing pipe 111b is equal to the number of the flat tube holes 1111 of the first condensing pipe 111a; or, the cross-sectional area of the flat tube hole 1111 of the second condensing pipe 111b can be selected to be equal to the cross-sectional area of the flat tube hole 1111 of the first condensing pipe 111a, and the number of the flat tube holes 1111 of the second condensing pipe 111b is greater than the number of the flat tube holes 1111 of the first condensing pipe 111a; or, the cross-sectional area of the flat tube hole 1111 of the second condensing pipe 111b can be selected to be greater than the cross-sectional area of the flat tube hole 1111 of the first condensing pipe 111a, and the number of the flat tube holes 1111 of the second condensing pipe 111b is greater than the number of the flat tube holes 1111 of the first condensing pipe 111a; or, the cross-sectional area of the flat tube hole 1111 of the second condensing pipe 111b can be selected to be greater than the cross-sectional area of the flat tube hole 1111 of the first condensing pipe 111a, and the number of the flat tube holes 1111 of the second condensing pipe 111b is less than the number of the flat tube holes 1111 of the first condensing pipe 111a; or, the cross-sectional area of the flat tube hole 1111 of the second condensing pipe 111b can be selected to be less than the cross-sectional area of the flat tube hole 1111 of the first condensing pipe 111a, and the number of the flat tube holes 1111 of the second condensing pipe 111b is greater than the number of the flat tube holes 1111 of the first condensing pipe 111a.

[0196] In actual cases, the material hardness of the second condensing pipe 111b can be less than that of the first condensing pipe 111a, so that the burst pressure of the second condensing pipe 111b is less than that of the first condensing pipe 111a, when the material of the second condensing pipe 111b and the material of the first condensing pipe 111a are the same kind of material. For example, the second condensing pipe 111b and the first condensing pipe 111a are both metal pipes, and the material hardness of the second condensing pipe 111b is less than that of the first condensing pipe 111a.

[0197] As described above, the heat sink 10 includes the condensing end 11, the condensing end 11 includes the condensing pipe 111 and the manifold 112, the manifold 112 includes one of the first manifold 112a and the second manifold 112b, and at least one of the condensing pipe 111, the first manifold 112a and the second manifold 112b is the second burst component 16. Of course, the manifold 112 can also be one, and at least one of the condensing pipe 111 and the manifold 112 is the second burst component 16.

[0198] As described above, the heat sink 10 includes the injection pipe 15, as shown in Figure 6 The injection pipe 15 can be selected as the second burst component 16. Since the injection pipe 15 has a certain length, the injection pipe 15 as the second burst component 16 can make the second burst component 16 as far as possible from other components of the heat sink 10, and can further reduce the damage caused by the explosion.

[0199] The burst pressure of the injection pipe 15 is less than the burst pressure of the component in which the injection pipe 15 is located, or the burst pressure of the third portion 161 of the injection pipe 15 is less than that of the fourth portion 162. For the distribution of the third portion 161 and the fourth portion 162 of the injection pipe 15, reference can be made to the distribution of the first portion 21 and the second portion 22 of the first burst component 20. In the case where the second burst component 16 is the injection pipe 15, the structure and type of the second burst component 16 can be referred to the first burst component 20, which will not be described here.

[0200] For the specific position of the injection pipe 15, reference can be made to the foregoing, which will not be described here.

[0201] In actual cases, the second burst component 16 can be one or more than two, and in the case where the second burst component 16 is more than two, at least two second burst components 16 are the same kind of channel component 101, for example, at least two second burst components 16 are both condensing pipes 111; or at least two second burst components 16 are different channel components 101, for example, one second burst component 16 is an injection pipe 15, and at least one second burst component 16 is a condensing pipe 111.

[0202] Based on the heat dissipation device 100 and the heat sink 10 with the second burst component 16 provided in the above embodiments, the embodiment of the present application further provides an electrical device, which comprises the heat dissipation device 100 or the heat sink 10 with the second burst component 16 provided in the above embodiments.
