Description

Technical Field

[0001] The utility model relates to the field of radiators, in particular to a radiator for a chassis. Background Art

[0002] The improvement of computer performance is often accompanied by an increase in power consumption. Some high-performance computers can generate heat of even over a thousand watts during operation. Currently, the heat sources inside the chassis (such as electronic components like CPUs, central processing units, or graphics card processors) have continuously increasing operating frequencies and speeds, and the heat they generate also increases accordingly, with the temperature rising continuously, seriously affecting the operating performance and stability of the electronic components. To solve the heat dissipation problem, radiators are usually installed inside the chassis for heat dissipation. The traditional heat dissipation solution using heat dissipation fans in existing radiators cannot meet the heat dissipation requirements of high-performance computers, and the heat dissipation capacity is maintained by stacking the number of fans.

[0003] The existing radiators also have the following defects:

[0004] 1) Existing radiators usually consist of a traditional motor and fan blades, and heat dissipation is achieved by driving the fan blades to rotate through the motor. Such radiators have the problem that the heat dissipation fan is prone to local overheating. During the rotation of the motor, the motor itself also generates heat. The motor drives the fan blades to dissipate heat from the heat source, but it cannot dissipate heat from the motor itself. When the heat generated by the computer during operation reaches over a thousand watts, the motor of the heat dissipation fan will burn out due to excessive temperature, further causing the heat dissipation fan to stop working and being unable to dissipate heat from the motor, easily resulting in local overheating and burnout of the heat dissipation fan.

[0005] 2) Existing radiators usually consist of a traditional motor and fan blades, and heat dissipation is achieved by driving the fan blades to rotate through the motor. Such radiators have the problems of poor heat dissipation performance and inability to expand the heat sink. When the models and types of heat sources are different, it is difficult for the heat dissipation fan to meet the heat dissipation requirements, and it is impossible to increase or decrease the area of the radiator, or to additionally install heat dissipation structures such as heat sinks on the radiator to improve the heat dissipation performance. It is impossible to flexibly adjust the number of heat sinks according to specific heat dissipation requirements, and the heat dissipation performance is not strong. For different heat sources, it is impossible to further improve the heat dissipation capacity. Summary of the Utility Model

[0006] In order to overcome the deficiencies of the existing technical solutions, the utility model provides a radiator for a chassis, which can effectively solve the technical problems that the heat dissipation fan inside the existing radiator is prone to local overheating and burning out, as well as poor heat dissipation performance and inability to expand the heat sink.

[0007] The technical solution adopted by the present utility model to solve its technical problems is as follows: A radiator for a chassis, comprising a housing, a cooling fan, and a heat conduction plate. The cooling fan is arranged inside the housing. One end of the housing is provided with a conductive air outlet, and the other end of the housing is provided with a conductive air inlet. The air direction of the cooling fan blows from the air inlet to the air outlet. The heat conduction plate is located outside the housing. One end of the housing extends outward to form an extension part. The extension part is provided with a plurality of extension plates arranged equidistantly. The inner wall of the extension plate is provided with a plurality of engaging elastic pieces arranged equidistantly. The side surface of the heat conduction plate extends outward to form a plurality of fixing plates arranged equidistantly. A fixing groove is formed between the plurality of fixing plates. The fixing groove extends along the length direction of the fixing plate. A heat conduction strip is welded to the top surface of the housing. One end of the heat conduction strip extends outward and is bent, and is welded to the heat conduction plate. The other end of the heat conduction strip extends outward to the outside of the housing. A metal tube is arranged inside the housing, and both ends of the metal tube are provided with conductive tube heads.

[0008] Further, one end of the heat conduction strip is provided with a substrate, the edge of the substrate is provided with a mounting plate, and screws are arranged on the surface of the mounting plate.

[0009] Further, two positioning blocks protruding upward are formed by extending one end of the housing outward. The two positioning blocks are symmetrically distributed.

[0010] Further, a plurality of screw holes are arranged on the edges of the housing and the fixing plate.

[0011] Further, a plurality of clamping blocks for fixing the metal tube are arranged inside the housing.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1) For the radiator for a chassis of the present utility model, by arranging a metal tube, coolant can be introduced. The coolant can surround the cooling fan to cool the cooling fan, and it can avoid the situation that the cooling fan is locally overheated and the cooling fan is burned out.

[0014] 2) The radiator of the present utility model for a chassis can effectively conduct heat to the outside quickly by setting heat conduction strips, with one end of the heat conduction strip welded to the heat conduction plate and the other end extending outside the housing, accelerating the heat dissipation, improving the heat dissipation efficiency, and greatly enhancing the heat dissipation performance of the radiator.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1 - 4As shown, a heat sink for a chassis includes a shell 1, a heat dissipation fan 3 and a heat conduction plate 2, wherein the heat dissipation fan 3 is composed of a motor and fan blades, and the motor drives the fan blades to blow air to achieve a heat dissipation function. The heat dissipation fan 3 is arranged inside the shell 1, and the inside of the shell 1 is a hollow structure. One end of the shell 1 is provided with a conductive air outlet 6, and the other end of the shell 1 is provided with a conductive air inlet 17. The wind direction of the heat dissipation fan 3 is from the air inlet 17 to the air outlet 6. When dissipating heat, the air outlet 6 is aligned with the heat source, and the heat is dissipated to the heat source through the heat dissipation fan 3. The heat source blows air to achieve heat dissipation, the heat conducting plate 2 is located outside the housing 1, and other heat sources (such as CPU, CPU, central processing unit or display card processor and other electronic components) can be installed on the heat conducting plate 2. One end of the housing 1 extends outward to form an extension part 8, and the extension part 8 is provided with a plurality of equally spaced extension plates 9. The inner wall of the extension plate 9 is provided with a plurality of equally spaced snap-fit spring pieces 15. By directly snapping the heat sink into the extension plate 9, the heat sink and the snap-fit spring piece 15 are in conflict with each other, so as to facilitate the installation of the heat sink. The side surface extends outward to form a plurality of fixed plates 12 arranged equidistantly, and a fixed groove 16 is formed between the plurality of fixed plates 12. The fixed groove 16 extends along the length direction of the fixed plate 12. The heat sink can be installed by sliding directly on the fixed plate 12, so that the heat sink is slidably connected to the fixed groove 16, which is convenient for installing the heat sink. A heat conducting strip 4 is welded on the top surface of the housing 1. One end of the heat conducting strip 4 extends outward and is bent, and is welded to the heat conducting plate 2. The other end of the heat conducting strip 4 extends outward to the outside of the housing 1. By setting the heat conducting strip 4 To further conduct the excess heat, a metal tube 18 is provided inside the shell 1, and conductive pipe heads 7 are provided at both ends of the metal tube 18. The pipe heads 7 can be conveniently connected to external water pipes, so as to facilitate the addition of coolant to the inside of the metal tube 18. The coolant circulates in the metal tube 18 to absorb the heat generated by the cooling fan 3, reduce the temperature of the cooling fan 3, and avoid local overheating of the cooling fan 3. The heat conducting strip 4, the heat conducting plate 2, the base plate 5, the expansion plate 9, and the fixing plate 12 are all made of metal copper and have strong thermal conductivity.

[0023] One end of the heat conduction strip 4 is provided with a substrate 5. An edge of the substrate 5 is provided with a mounting plate 13. A screw 14 is provided on the surface of the mounting plate 13. By providing the substrate 5, a heat source can be installed. By providing the mounting plate 13 and the screw 14, the substrate 5 can be fixed, facilitating the fixing of the substrate 5 at the installation position inside the chassis. One end of the housing 1 extends outwards to form two upwardly protruding positioning blocks 10. The two positioning blocks 10 are symmetrically distributed, enabling precise positioning of the radiator during installation and enabling the radiator to be fixed at the installation position inside the chassis. A plurality of screw holes 11 are provided at the edges of the housing 1 and the fixing plate 12. By providing the screw holes 11, screws can be inserted to facilitate the fixing of the radiator. A plurality of clamping blocks 19 for fixing the metal pipe 18 are provided inside the housing 1. The clamping blocks 19 are used to fix the metal pipe 18, preventing the metal pipe 18 from loosening or detaching due to external force or vibration.

[0024] A radiator for a chassis in this embodiment can pass coolant through the metal pipe 18. The coolant can surround the heat dissipation fan 3 to cool the heat dissipation fan 3, avoiding the situation of local overheating of the heat dissipation fan 3. By providing the heat conduction strip 4, one end of the heat conduction strip 4 is welded to the heat conduction plate 2, and the other end extends outside the housing 1, which can effectively conduct heat to the outside quickly, accelerating the dissipation of heat and improving the heat dissipation efficiency, greatly improving the heat dissipation performance of the radiator. By providing an extension part 8 and equally spaced extension plates 9 at one end of the housing 1, and providing a plurality of engaging elastic pieces 15 on the extension plates 9, heat dissipation fins can be additionally added by an engaging method. By providing the fixing plate 12 and the fixing groove 16, heat dissipation fins can be additionally added by a sliding method, increasing the heat dissipation area of the radiator, facilitating the increase of the number and layout of heat dissipation fins according to specific heat dissipation requirements, greatly improving the heat dissipation efficiency of the radiator, and facilitating the additional installation of heat dissipation fins on the radiator.

[0025] During installation, the radiator is installed at the installation position inside the chassis by inserting fasteners such as screws into the screw holes 11. The substrate 5 is fixed at the installation position inside the chassis by the screw 14. At the same time, a heat source is installed at one end of the air outlet 6 of the housing 1, on the substrate 5, and on the heat conduction plate 2. During heat dissipation, the air outlet 6 is aligned with the heat source, and heat dissipation is achieved by blowing air from the heat dissipation fan 3 towards the heat source. Part of the heat generated by the heat source can be quickly conducted through the heat conduction strip 4, enabling the heat to be directly conducted into the air. The pipe head 7 is connected to an external water pipe. By adding coolant into the metal pipe 18 and circulating the coolant in the metal pipe 18, the heat generated by the heat dissipation fan 3 can be absorbed, reducing the temperature of the heat dissipation fan 3. Heat dissipation fins are additionally added on the extension plates 9 by an engaging method, and heat dissipation fins are added on the fixing plate 12 and the fixing groove 16 by a sliding method, increasing the heat dissipation area of the radiator and further improving the heat dissipation performance.
