Description

Technical Field

[0001] The utility model relates to the technical field of controller equipment, in particular to a controller heat dissipation structure. Background Art

[0002] A controller is a main command device that changes the wiring of the main circuit or control circuit and the resistance value in the circuit in a predetermined order to control the starting, speed regulation, braking and reversal of the motor.

[0003] The controller is generally composed of a heat dissipation shell and a circuit board. The heat dissipation shell is usually made of metal, and heat dissipation fins are provided on the top and both sides of the surface. The overall volume is small, especially for vehicle-mounted controllers. Due to the limited space inside the vehicle, in order to ensure that the controller can be installed normally in the vehicle, the volume control of the vehicle-mounted controller is more stringent, so conventional heat dissipation fans cannot be used for heat dissipation;

[0004] Most of them are heat dissipated by setting up a heat dissipation shell. When the circuit board generates heat internally, the heat is dissipated through the heat dissipation shell and the heat dissipation fins, that is, the good thermal conductivity of metal is used to dissipate the heat through the metal shell and the external air to achieve the heat dissipation effect. This heat dissipation method will make the entire controller a heat source. At this time, the heat is evenly dissipated outward, which causes the air around the controller to be exchanged and become hot air. The essence of heat exchange is that heat is transferred from high temperature to low temperature. Therefore, when the temperature around the controller rises, the heat exchange process is blocked, that is, the heat exchange effect is weakened, resulting in poor heat exchange effect;

[0005] However, passive heat dissipation relying solely on heat dissipation fins has a poor heat dissipation effect, so a controller heat dissipation structure is proposed to solve the above-mentioned problem. Utility Model Content

[0006] Based on the above description, the utility model provides a controller heat dissipation structure to solve the problem of poor heat dissipation effect of existing vehicle-mounted controllers.

[0007] The utility model solves the above-mentioned technical problem with the following technical solution: a controller heat dissipation structure, installed on a controller body, the controller body comprising a heat dissipation shell and a mounting groove, the mounting groove being arranged on both sides of the heat dissipation shell, the heat dissipation component comprising a metal substrate, a metal heat dissipation column and a metal heat dissipation plate, the metal substrate being arranged inside the mounting groove, the metal heat dissipation column and the metal heat dissipation plate being both arranged on the surface of the metal substrate, and side covers being arranged on both sides of the controller body by screws.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, a V-shaped bottom surface is provided on the lower surface of the heat dissipation shell, a lower heat dissipation fin is provided at the bottom end of the V-shaped bottom surface, and an upper heat dissipation fin is provided at the top end of the heat dissipation shell.

[0010] Furthermore, the installation groove includes a placement groove and an ear groove, and a threaded blind hole is arranged inside the ear groove.

[0011] Furthermore, mounting ears are provided on both sides of the metal substrate, and the mounting ears are arranged inside the ear grooves.

[0012] Furthermore, a second through hole is provided on the surface of the mounting ear, and the second through hole corresponds to the threaded blind hole.

[0013] Furthermore, the side cover includes a cover body, and a fixing ear plate is provided on a side of the cover body away from the controller body.

[0014] Furthermore, a positioning protrusion is provided on one side of the cover body close to the controller body, and the positioning protrusion extends to the inside of the ear groove, and the height of the cover body is greater than the height of the metal substrate.

[0015] Furthermore, a first through hole penetrating the positioning protrusion is provided on the surface of the cover body, and the first through hole corresponds to the threaded blind hole.

[0016] Furthermore, the screw passes through the first through hole and the second through hole in sequence and is threadedly connected with the threaded blind hole.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] 1. The utility model provides side covers and heat sinks and other components, and the heat sinks and the controller body cooperate to transfer the heat of the controller body to the heat sink. At this time, the air between the controller body and the side covers is heated up, and the density of the heated air is reduced, so it flows upward, that is, an upward airflow is generated between the controller body and the side covers;

[0019] 2. By setting the V-shaped bottom surface and the lower heat dissipation fins, the effect of guiding the directional flow of air is achieved, so that the air below the controller body can flow along the direction of the V-shaped bottom surface after being heated up. During the flow, the lower heat dissipation fins are restricted to ensure that the hot air can enter the space between the controller body and the side cover. Through the directional flow of airflow, the effect of accelerating the flow of air outside the controller body is achieved, making the heat dissipation effect better.

However, the present application can be implemented in many different forms and is not limited to the embodiments described herein.

It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0031] See also Figure 1-Figure 4A controller heat dissipation structure is installed on a controller body 1, wherein the controller body 1 includes a heat dissipation housing 11 and a mounting slot 12, wherein:

[0032] The mounting grooves 12 are arranged on both sides of the heat dissipation housing 11. The mounting grooves 12 include placement grooves and ear grooves. The ear grooves are provided with threaded blind holes 13;

[0033] The lower surface of the heat dissipation housing 11 is provided with a V-shaped bottom surface 14, the bottom end of the V-shaped bottom surface 14 is provided with a lower heat dissipation fin 15, and the top end of the heat dissipation housing 11 is provided with an upper heat dissipation fin 16;

[0034] Based on the above, the upper heat sink 16 and the lower heat sink 15 both have the effect of heat dissipation, that is, transferring heat energy, so that the heat energy inside the controller body 1 is exchanged with the air, and the setting of the V-shaped bottom surface 14 allows the air below the controller body 1 to move along the direction of the V-shaped bottom surface 14 and the lower heat sink 15 after heating, that is, it is ensured that the air can enter between the controller body 1 and the side cover 2, and the setting of the threaded blind hole 13 allows the side cover 2 and the heat sink 3 to be connected and fixed to the controller body 1 by screws.

[0035] like Figure 1 , Figure 2 and Figure 6 As shown, the heat sink 3 includes a metal substrate 31, a metal heat sink column 33 and a metal heat sink plate 34, wherein:

[0036] A metal substrate 31 is disposed inside the mounting groove 12, and mounting ears 32 are disposed on both sides of the metal substrate 31. The mounting ears 32 are disposed inside the ear grooves, and a second through hole 35 is disposed on the surface of the mounting ears 32. The second through hole 35 corresponds to the threaded blind hole 13;

[0037] Metal heat dissipation columns 33 and metal heat dissipation plates 34, which are arranged on the surface of the metal substrate 31;

[0038] Based on the above, the heat sink 3 plays a role in gathering heat. The heat generated inside the controller body 1 is transferred from the heat dissipation shell 11 to the metal substrate 31, the metal heat dissipation plate 34 and the metal heat dissipation column 33, and achieves a heat exchange effect with the air. At this time, the density of the air decreases after heating, causing the hot air to flow upward, that is, a directional airflow is generated. Through the setting of the second through hole 35, the heat sink 3 can be fixed by screws.

[0039] like Figure 1 , Figure 2 and Figure 3As shown, the side cover 2 is set on both sides of the controller body 1 by screws, and the side cover 2 includes a cover body 21, and a fixing ear plate 22 is set on the side of the cover body 21 away from the controller body 1, and a positioning protrusion 23 is set on the side of the cover body 21 close to the controller body 1, and the positioning protrusion 23 extends to the inside of the ear groove. The height of the cover body 21 is greater than the height of the metal substrate 31, and the surface of the cover body 21 is provided with a first through hole 24 that penetrates the positioning protrusion 23, and the first through hole 24 corresponds to the threaded blind hole 13;

[0040] Based on the above, the setting of the side cover 2 plays a role in limiting the direction of airflow. When the heat sink 3 heats the air into hot air, the hot air can only move vertically, through the cover body 21 whose height is greater than the metal substrate 31, so that the air below the controller body 1 can be hindered when moving horizontally along the V-shaped bottom surface 14, so as to ensure that the air can enter the space between the side cover 2 and the controller body 1.

[0041] In actual use of this embodiment, the heat sink 3 and the side cover 2 are installed on both sides of the controller body 1 by screws, and the metal substrate 31 is located inside the installation groove 12;

[0042] When the controller body 1 is working, heat is generated inside it, and the heat is exchanged with the external air through the heat dissipation shell 11. The lower heat dissipation fins 15 exchange heat with the air below the controller body 1, so that the air is heated up to become hot air. The hot air moves laterally along the direction of the V-shaped bottom surface 14 and the lower heat dissipation fins 15, that is, flows toward the direction close to the side cover 2, and the flowing airflow flows into the space between the side cover 2 and the controller body 1;

[0043] Part of the heat generated by the controller body 1 is transferred to the heat sink 3, and heat is exchanged with the air between the side cover 2 and the controller body 1 through the metal heat sink 33 and the metal heat sink plate 34, that is, the air is heated, so that the air is heated to become hot air, and the hot air flows upward at this time;

[0044] The two streams of hot air mentioned above continue to flow after converging, generating a top airflow, which drives the air in other positions when flowing, thereby enabling the air around the controller body 1 to flow and form a directional airflow. Compared with traditional controllers, the air flow can drive cold air to flow around the controller body 1 to achieve an enhanced heat dissipation effect.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
