Description

Technical Field

[0001] The invention belongs to the technical field of heat dissipation, and in particular relates to a radiator. Background Art

[0002] With the development of the times, the intelligent trend of various products is becoming more and more obvious. The higher the degree of integration of electronic digital circuits, the higher the heat generation. In order to reduce heat dissipation, it is generally necessary to add a radiator to the product to ensure the normal operation of the electronic equipment.

[0003] Conventional radiators include expansion tube radiators and tube-belt radiators. Heat is dissipated by passing a heat transfer fluid, such as water, through the heat pipe.

[0004] The expansion tube radiator includes a heat dissipation tube and a heat dissipation fin, which are arranged in an array along the axial direction of the heat dissipation tube and ensured to be parallel to each other. A through hole is opened on the heat dissipation fin. The heat dissipation tube passes through the through hole and is expanded by the tube expander so that the heat dissipation tube abuts against the inner wall of the through hole to fix the heat dissipation fin and the heat dissipation tube.

[0005] Among them, the tube-belt radiator includes a heat pipe and a heat belt. The heat belt is wavy and consists of multiple heat sinks. The heat sinks are connected end to end and folded back repeatedly. The two ends of each heat sink are welded to the heat pipe respectively, thereby fixing the heat belt and the heat pipe.

[0006] However, the above radiators are all made of multiple parts fixed together. When the heat flows from the heat pipe to the heat sink, the heat insulation effect will inevitably affect the heat conduction efficiency, which has an adverse effect on the heat dissipation process of the radiator.

[0007] Therefore, it is urgent to design a radiator to solve the above-mentioned problems. Summary of the invention

The heat transfer component is connected to a heat dissipation component. A heat transfer fluid is arranged in the heat transfer component. Heat dissipation grooves are integrally formed on the heat sink. The heat dissipation grooves are connected in sequence to form a heat dissipation channel. The heat dissipation channel is used for the heat transfer fluid to circulate. A first direction end of the heat dissipation channel is connected to the heat transfer component so that the heat carried by the heat transfer fluid is transferred to the heat sink through the heat dissipation channel.

[0010] Furthermore, the heat sink includes a first sheet body and a second sheet body, the first sheet body and the second sheet body are fixedly connected, and heat dissipation grooves are integrally formed on the first sheet body and the second sheet body.

[0011] Furthermore, the heat dissipation grooves on each first sheet are connected in sequence to form a first heat dissipation channel, and the heat dissipation grooves on each second sheet are connected in sequence to form a second heat dissipation channel. The first heat dissipation channel is connected to the second heat dissipation channel through a heat transfer component.

[0012] Furthermore, the heat transfer component includes a heat transfer base and a heat pipe, the heat transfer base is connected to the heat dissipation component, the middle of the heat pipe is connected to the heat transfer base, and both ends of the heat pipe are respectively connected to the first heat dissipation channel and the second heat dissipation channel.

[0014] Furthermore, when the heat dissipation slots are connected in sequence to form a heat dissipation channel, the heat dissipation fins are connected in sequence to form a heat dissipation assembly, a heat dissipation hole is provided in the heat dissipation assembly, and an exhaust assembly is provided in the heat dissipation hole.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0022] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0023] Please refer to the attached Figure 1 To Attachment Fig.11 A heat sink of the present invention is described.

[0024] At present, existing radiators are all made of multiple parts fixed together. When heat flows from the heat pipe to the heat sink, the heat insulation effect will inevitably affect the heat conduction efficiency, causing an adverse effect on the heat dissipation process of the radiator.

[0025] Therefore, the radiator includes a heat transfer component 3 and a plurality of heat sinks 11. The heat transfer component 3 is connected to the heat dissipation component. A heat transfer fluid is arranged in the heat transfer component 3. Heat dissipation grooves 21 are integrally formed on the heat sink 11. The heat dissipation grooves 21 are connected in sequence to form a heat dissipation channel 2. The heat dissipation channel 2 is used for the heat transfer fluid to circulate. The first direction A end of the heat dissipation channel 2 is connected to the heat transfer component 3, so that the heat carried by the heat transfer fluid is transferred to the heat sink 11 through the heat dissipation channel 2.

[0026] After the heat sink is connected, heat transfer liquid is placed on the heat transfer component through the second direction B end of the heat dissipation channel, and then the second direction B end of the heat dissipation channel is sealed.

[0027] The heat dissipation channel 2 is integrally formed by the heat sink 11, eliminating the heat insulation effect, so that heat can be efficiently transferred from the heat transfer liquid in the heat pipe to the fins through the heat dissipation fins, thereby improving the heat dissipation efficiency of the radiator. Moreover, through this heat dissipation method, the radiator can be made of aluminum material, which greatly saves costs compared to the copper material in the prior art.

[0028] In order to make the heat sink 11 and the heat sink 21 integrally formed, different manufacturing processes can be used. Preferably, a stamping process is used. Specifically, each heat sink 11 is provided with a corresponding heat sink 21, and the heat sink 21 extends in the first direction A. Through the stamping process, the waste generated by opening holes in the heat sink 11 is reduced, and this part of the waste is converted into the wall surface of the heat dissipation channel 2, thereby saving material costs. In other embodiments of the present invention, the heat sink 21 can also extend in the second direction B, as long as the heat sink 21 and the heat sink 11 are integrally formed.

[0029] When the heat dissipation slots 21 are connected in sequence to form the heat dissipation channel 2, the heat dissipation fins 11 are connected in sequence to form the heat dissipation assembly 1. The heat dissipation assembly 1 is composed of a plurality of heat dissipation fins 11. The specific number of the heat dissipation fins 11 can be set according to actual conditions and is not limited in the present invention.

[0030] When the edge of the heat dissipation slot 21 extends along the first direction A, and in the heat dissipation assembly 1, the end of the heat dissipation slot 21 of the heat sink 11 located at the second direction B end is welded and fixed to the starting end of the heat dissipation slot 21 of the heat sink 11 adjacent to its first direction A end, and the starting end of the heat dissipation slot 21 of the heat sink 11 at the first direction A end is welded and fixed to the end of the heat dissipation slot 21 of the heat sink 11 adjacent to its second direction B end, and the connection, fixation and sealing of each heat dissipation slot 21 are achieved by welding to form a heat dissipation channel 2.

[0031] When the edge of the heat dissipation slot 21 extends along the second direction B, and in the heat dissipation assembly 1, the starting end of the heat dissipation slot 21 of the heat sink 11 located at the second direction B end is welded and fixed to the end of the heat dissipation slot 21 of the heat sink 11 adjacent to its first direction A end, and the end of the heat dissipation slot 21 of the heat sink 11 at the first direction A end is welded and fixed to the starting end of the heat dissipation slot 21 of the heat sink 11 adjacent to its second direction B end, and the connection, fixation and sealing of each heat dissipation slot 21 are achieved by welding to form a heat dissipation channel 2.

[0032] The heat sink 11 includes a first sheet 111 and a second sheet 112, which are fixedly connected. The first sheet 111 and the second sheet 112 are integrally formed with a heat dissipation groove 21. In other embodiments of the present invention, a third sheet, a fourth sheet, etc. may also be included as long as the heat sink 11 can be formed.

[0033] Specifically, the heat dissipation grooves 21 on each first plate 111 are connected in sequence to form a first heat dissipation channel, and the heat dissipation grooves 21 on each second plate 112 are connected in sequence to form a second heat dissipation channel. The first heat dissipation channel and the second heat dissipation channel are connected through the heat transfer component 3, so that the heat of the heat dissipation component of the heat transfer component 3 is transferred to the heat transfer component 3. As the temperature rises, the heat transfer fluid in the heat transfer component 3 evaporates at high temperature and flows to the heat dissipation channel 2, and then is cooled by the heat dissipation component 1, forming a cyclic heat dissipation process. Moreover, by setting the first heat dissipation channel and the second heat dissipation channel, the heat transfer fluid can dissipate heat to the first heat dissipation channel and / or the second heat dissipation channel, further accelerating the heat dissipation speed.

[0034] Preferably, the specific number of the first heat dissipation channel and the second heat dissipation channel are both five, and the corresponding first heat dissipation channels and the second heat dissipation channels are connected through the heat transfer component 3. In other embodiments of the present invention, the number of the first heat dissipation channels and the second heat dissipation channels can also be set according to actual conditions.

[0035] Preferably, the first sheet 111 and the second sheet 112 are both semicircular arc-shaped. When the first sheet 111 and the second sheet 112 are welded and fixed to form a heat sink 11, the heat sink 11 is circular. When multiple heat sinks 11 form a heat sink assembly 1, the heat sink assembly 1 is cylindrical.

[0036] The heat transfer component 3 includes a heat transfer base 31 and a heat pipe 32. The heat transfer base 31 is connected to the heat dissipation component. The middle part of the heat pipe 32 is connected to the heat transfer base 31. The two ends of the heat pipe 32 are respectively connected to the first heat dissipation channel and the second heat dissipation channel. Specifically, the heat transfer base 31 and the heat pipe 32 are both made of aluminum, which further saves material costs.

[0037] Regarding the first embodiment of the heat transfer base 31 , the heat conduction pipe 32 passes through two side surfaces of the heat transfer base 31 , so that the heat conduction pipe 32 extends to both ends of the heat transfer base 31 to connect with the first heat dissipation channel and the second heat dissipation channel.

[0038] Regarding the second embodiment of the heat transfer base 31 , the heat conduction pipe 32 passes through the top surface of the heat transfer base 31 , so that the heat conduction pipe 32 extends outside the top surface of the heat transfer base 31 to connect with the first heat dissipation channel and the second heat dissipation channel.

[0039] A heat dissipation hole is provided in the heat dissipation component 1, and an exhaust component 4 is provided in the heat dissipation hole. Specifically, the exhaust component 4 includes an exhaust fan 43 and a motor 41. The output end of the motor 41 is fixedly connected to a rotating shaft 42, and the rotating shaft 42 is connected to the exhaust fan 43. The exhaust fan 43 is located in the heat dissipation hole, so that air is sucked in from the second direction B end of the heat dissipation component 1, and the heat on the heat sink 11 is blown away by blowing the air out from the annular surface of the heat dissipation component 1.

[0040] The exhaust fan 43 includes an upper connecting ring, fan blades 432 and a lower connecting ring 431. The upper connecting ring and the lower connecting ring 431 are fixedly connected by the fan blades 432. The upper connecting ring is connected to the exhaust fan 43. The fan blades 432 are arranged at an angle, so that when heat is dissipated, the annular surface of the heat dissipation component 1 can be dissipated all around, thereby improving the heat dissipation efficiency.

[0041] The first direction A end of the heat dissipation component 1 is connected to a lower mounting plate 13, and the second direction B end of the heat dissipation component 1 is connected to an upper mounting plate 12. Specifically, a second connecting hole 131 is provided on the lower mounting plate 13, and the second connecting hole 131 may be the same as the heat dissipation groove 21, or may only be a hole body. The second connecting hole 131 is connected to the first direction A end of the heat dissipation channel 2. A first connecting hole 121 is provided on the upper mounting plate 12, and the first connecting hole 121 is the same as the heat dissipation groove 21. The first connecting hole 121 is connected to the second direction B end of the heat dissipation channel 2. The upper mounting plate 12 is also provided with a mounting hole 122, which can be fixed to the motor bracket 5 through the mounting hole 122, and the motor bracket 5 is connected and fixed to the power supply machine 41.

[0042] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. 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 embodiments here.
