Heat dissipation case

Abstract

The utility model discloses a heat dissipation case, which belongs to the technical field of heat dissipation equipment, and comprises a case body, and heat dissipation tooth sheets and a fan assembly which are arranged in the case body, the fan assembly comprises a cross-flow fan; the cross-flow fan is of a columnar structure; blades are arranged on the outer side face of the cross-flow fan in the circumferential direction. The heat dissipation tooth pieces comprise heat dissipation channels with air inlets facing the blades. Due to the fact that the cross-flow fan can form strong wind under the condition that the radial size of the cross-flow fan is extremely small, even if the cross-flow fan is arranged in the case body with the narrow internal space, the cross-flow fan can still be matched with the heat dissipation tooth pieces to achieve heat dissipation work, and therefore the electronic equipment can meet the requirements for strong heat dissipation and exquisite heat dissipation at the same time.

Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation equipment, and particularly relates to a heat dissipation chassis. Background Art

[0002] With the rapid development of modern science and technology, people not only put forward requirements for the performance of electronic equipment, but also continue to move towards intensification and refinement in terms of the space occupancy rate of electronic equipment. For this reason, in the design and production process of electronic equipment, a large number of electronic components will be arranged in a chassis with limited space, so as to achieve the functional combination of high performance and low space occupancy rate.

[0003] However, in actual use, it is found that high-performance products often have problems of high power consumption and high heat generation. In addition, due to the small size of such electronic devices, heat can easily accumulate quickly inside the chassis, causing the operating temperature to rise rapidly, which in turn affects the performance of the electronic equipment.

[0004] In order to solve this problem, corresponding heat conduction and heat dissipation equipment, such as heat sink fins and cooling fans, are usually added to the chassis of such electronic equipment. However, due to the limited internal space of the chassis, if the heat sink fins occupy a large volume, the volume left for the cooling fan will be reduced accordingly. Conventional cooling fans (centrifugal fans and axial fans) usually have a large cross-section and need to occupy a large volume. In order to prevent foreign matter from entering the electronic equipment, the air outlet size of the chassis is generally designed to be relatively small. This leads to the problem of heat dissipation inconsistency between the heat sink fins and the cooling fan, making it impossible to take into account the global heat dissipation of the equipment, and only local heat dissipation can be achieved, which will still affect the overall heat dissipation and working performance. Utility Model Content

[0038] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0039] The most critical concept of the utility model is that since the cross-flow fan can form strong wind with extremely small radial dimensions, even if it is set in a chassis body with a narrow internal space, it can still cooperate with the heat dissipation teeth to achieve heat dissipation, so that the electronic equipment can meet the requirements of strong heat dissipation and compactness at the same time.

[0040] Please refer to Figures 1 to 3 The heat dissipation chassis provided by the utility model comprises a chassis body 1, and heat dissipation fins 2 and a fan assembly 3 arranged in the chassis body 1;

[0041] The fan assembly 3 includes a cross-flow fan 31;

[0042] The cross-flow fan 31 is a columnar structure;

[0043] The outer side surface of the cross-flow fan 31 is provided with blades in the circumferential direction;

[0044] The heat dissipation fins 2 include heat dissipation channels 21 with air inlets disposed toward the blades.

[0045] From the above description, it can be seen that the beneficial effects of the utility model are: providing a heat dissipation chassis, in which the cross-flow fan 31 can generate strong wind when its own radial size is extremely small, so even if it is set in a chassis body 1 with a narrow internal space, it can still cooperate with the heat dissipation fins 2 to achieve heat dissipation; compared with the fans in the existing chassis, the air volume generated by the cross-flow fan 31 is only related to the length of the fan extending along its own axis, thereby avoiding the problem of the radial size of the fan not matching the chassis body 1 and the heat dissipation fins 2, which affects the installation and heat dissipation effect, and thus provides structural support for electronic equipment to simultaneously meet the requirements of strong heat dissipation and compactness.

[0046] Furthermore, the chassis body 1 is a cubic structure;

[0047] The fan assembly 3 is arranged at the bottom of the chassis body 1;

[0048] The axis of the cross-flow fan 31 is parallel to the length direction of the chassis body 1 .

[0049] Furthermore, the chassis body 1 is provided with heat dissipation holes 11 at one end thereof in the height direction and opposite to the cross-flow fan 31;

[0050] The chassis body 1 is provided with air inlet holes 12 in an array at one end thereof in the width direction and close to the cross-flow fan 31 .

[0051] Preferably, in the length direction of the chassis body 1 , the arrangement size of the heat sink fins 2 , the axial size of the cross-flow fan 31 and the arrangement size of the heat dissipation holes 11 are all consistent, and the heat sink fins 2 and the cross-flow fan 31 are both within the projection area of ​​the heat dissipation holes 11 .

[0052] From the above description, it can be seen that since the weight of cold air is slightly heavier than that of hot air under the same volume, the fan assembly 3 is arranged at the bottom of the chassis body 1, and the air inlet 12 is arranged close to the cross-flow fan 31. The cold air from the outside can be brought into the inside of the chassis body 1 under the drive of the cross-flow fan 31. At the same time, under the further agitation of the cross-flow fan 31, the strong cold air can discharge the heat absorbed by the heat dissipation teeth 2 to the outside along the heat dissipation holes 11, thereby achieving the effect of heat dissipation and cooling of the components in the chassis body 1.

[0053] Furthermore, a support plate 13 is provided in the chassis body 1;

[0054] The heat dissipation fins 2 are connected to the chassis body 1 through a support plate 13;

[0055] The heat dissipation fins 2 are disposed between the heat dissipation holes 11 and the cross-flow fan 31 .

[0056] Furthermore, the heat dissipation fins 2 include heat conducting fins 22 arranged at equal intervals along the length direction of the chassis body 1;

[0057] A heat dissipation channel 21 is formed between adjacent heat conducting sheets 22;

[0058] The length direction of the heat dissipation channel 21 is parallel to the flow direction of the airflow;

[0059] The air inlet of the heat dissipation channel 21 is arranged toward the blades;

[0060] The air outlet of the heat dissipation channel 21 is arranged toward the heat dissipation hole 11 .

[0061] From the above description, it can be seen that the design has made specific modifications to the layout and component structure of the heat dissipation teeth 2, ensuring that the length direction of the heat dissipation channel 21 formed by the heat conductive sheet 22 is parallel to the flow direction of the airflow, and that the air inlet and air outlet of the heat dissipation channel 21 are respectively arranged toward the blades and the heat dissipation holes 11, thereby reducing the resistance to gas flow, so that heat can be discharged from the chassis body 1 more smoothly, thereby making the overall cooling effect more obvious.

[0062] Furthermore, the heat conducting sheet 22 is provided with ventilation holes 221 at equal intervals along its length direction.

[0063] It can be seen from the above description that the ventilation holes 221 can enhance the fluidity of the airflow between the heat conducting plates 22, thereby further reducing the resistance of the air flow, and thus allowing the heat absorbed by the heat conducting plates 22 to be discharged from the chassis body 1 more quickly.

[0064] Furthermore, a boss 23 is provided on one side of the heat dissipation fin 2 close to the support plate 13 .

[0065] Specifically, the support plate can also be used to fix various components, so the size, quantity and distribution position of the bosses 23 can be adaptively adjusted according to the actual situation of the components arranged on the support plate.

[0066] From the above description, it can be seen that the boss 23 provides structural support for the heat sink 2 to be provided with a corresponding thermal conductive paste or thermal conductive silicone, so that the heat sink 2 can be in contact with the relevant components on the support plate 13 through the thermal conductive paste or thermal conductive silicone, so that the heat generated by the components can be transferred to the heat sink 2 more quickly, and then the heat is taken away in the process of cold air flowing through the heat sink 2.

[0067] Furthermore, the heat dissipation fin 2 also includes an avoidance notch 24 .

[0068] From the above description, it can be seen that since the internal space of the chassis body 1 is limited and the size of some components is large, corresponding avoidance gaps 24 are provided on the heat sink 2 to prevent the heat sink 2 from interfering with these components during installation and use.

[0069] Furthermore, the fan assembly 3 also includes a driving motor;

[0070] The rotating shaft of the cross-flow fan 31 is connected to the movable end of the driving motor.

[0071] It can be seen from the above description that the driving motor provides power support for the cross-flow fan 31 to generate strong wind.

[0072] The heat dissipation chassis of the utility model can assist the heat dissipation work of electronic components.

[0073] Please refer to Figures 1 to 3 , Embodiment 1 of the present utility model is:

[0074] A heat dissipation chassis comprises a chassis body 1, and a support plate 13, heat dissipation fins 2 and a fan assembly 3 arranged in the chassis body 1; the fan assembly 3 comprises a driving motor and a cross-flow fan 31; the cross-flow fan 31 is a columnar structure; the rotating shaft of the cross-flow fan 31 is connected to the movable end of the driving motor, and blades are circumferentially arranged on the outer side surface of the cross-flow fan 31; the heat dissipation fins 2 comprise a heat dissipation channel 21 arranged with an air inlet facing the blades; the heat dissipation fins 2 are connected to the chassis body 1 through the support plate 13; a boss 23 is provided on the side of the heat dissipation fins 2 close to the support plate 13; the heat dissipation fins 2 also include an avoidance notch 24.

[0075] The chassis body 1 is a cubic structure; the fan assembly 3 is arranged at the bottom of the chassis body 1; the axis of the cross-flow fan 31 is parallel to the length direction of the chassis body 1; the chassis body 1 is provided with a heat dissipation hole 11 at one end array in its height direction and opposite to the cross-flow fan 31; the chassis body 1 is provided with an air inlet hole 12 at one end array in its width direction and close to the cross-flow fan 31; the heat dissipation fins 2 are arranged between the heat dissipation hole 11 and the cross-flow fan 31.

[0076] The heat dissipation fins 2 include heat conductive sheets 22 that are evenly spaced along the length direction of the chassis body 1; a heat dissipation channel 21 is formed between adjacent heat conductive sheets 22; the length direction of the heat dissipation channel 21 is parallel to the flow direction of the airflow; the air inlet of the heat dissipation channel 21 is arranged toward the blades; the air outlet of the heat dissipation channel 21 is arranged toward the heat dissipation hole 11; the heat conductive sheet 22 is provided with ventilation holes 221 at even intervals along its own length direction.

[0077] The working principle of the utility model is as follows: first, the components on the support plate 13 transfer the heat generated during operation to the heat conductive sheet 22 of the heat dissipating tooth sheet 2 through the heat conductive paste or heat conductive silica gel provided on the boss 23 of the heat dissipating tooth sheet 2; then, driven by the cross-flow fan 31, the cold air from the outside is first brought into the interior of the chassis body 1, and at the same time, under the further agitation of the cross-flow fan 31, the strong cold air flows through the heat dissipating channel 21 between the heat conductive sheets 22, so that the heat absorbed by the heat conductive sheets 22 is discharged to the outside along the heat dissipating holes 11, thereby achieving the effect of heat dissipation and cooling of the components in the chassis body 1.

[0078] In summary, the utility model provides a heat dissipation chassis, because the cross-flow fan can form strong wind when its own radial size is extremely small, so even if it is set in a chassis body with a small internal space, it can still cooperate with the heat dissipation fins to achieve heat dissipation; compared with the fan in the existing chassis, the air volume generated by the cross-flow fan is only related to the length of the fan extending along its own axis, thereby avoiding the problem of the fan radial size not matching the chassis body and the heat dissipation fins affecting the installation and heat dissipation effect, and then providing structural support for electronic equipment to meet the requirements of strong heat dissipation and exquisiteness at the same time. It effectively solves the problem that the heat dissipation fins and fans in the existing chassis cannot achieve heat dissipation balance due to the inability to coordinate performance.
