[0002] With the popularization of high-power electronic products, the heat dissipation problem of heat-generating electronic components is also unfolding at the same time. At present, there are two main ways to dissipate heat for the circuit board inside the electronic control box. One is to install a fan inside the box and make holes in the shell to allow cold air to flow through the circuit board, but this hole-opening method cannot achieve the problem of outdoor waterproofing. The other is to place the circuit board in a completely sealed box, and install a fan outside the box to cool the box shell to achieve heat dissipation of the internal components. Due to the large thermal resistance between the heat-generating part and the box shell, the efficiency of this heat dissipation method is extremely low. In order to solve the above problems, the present invention proposes a heat dissipation device in a closed box to achieve the functions of effective waterproofing and efficient heat dissipation.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] See also Figure 1-5 The present invention provides a technical solution: a closed box heat dissipation system, mainly including a device housing 1, an electronic device 2, a heat absorption module 3 and a fan 4. The device main housing 11, the front cover 12 and the air inlet connector 311, the air outlet connector 312 and the cable connector installed thereon form a closed space structure in the entire box, which can effectively prevent the corrosion of external dust, moisture, etc. on the internal electronic equipment. At the same time, a heat absorption module 3 is provided, and the airflow generated by the fan 4 in the heat dissipation pipeline placed in the box enters and carries the heat absorbed from the inner wall to the external environment, which is beneficial to the operation of the heat dissipation system. The specific technical solution is as follows: The device housing 1 is configured as a closed structure, the electronic device 2 is installed inside the device housing 1, a heat absorption module 3 is installed inside the device housing 1 and above the electronic device 2, the heat absorption module 3 is configured as a copper material, the fan 4 is provided with an exhaust port and is connected to the air inlet of the heat absorption module 3 through an air inlet joint 311, the heat absorption module 3 includes a main heat dissipation pipeline 31, an air inlet joint 311, an air outlet joint 312, a branch heat dissipation pipeline 32, a capillary heat dissipation pipeline 33 with an irregular shape structure, a capillary heat dissipation pipeline 34 with a square spiral structure, and a capillary heat dissipation pipeline 35 with a circular spiral structure, which are used to match the appearance of the heat-generating electronic components and tightly wrap and fit.
[0019] The heat absorption module 3 is provided with a capillary heat dissipation pipeline 33 with an irregular shape structure, a capillary heat dissipation pipeline 34 with a square spiral structure, and a capillary heat dissipation pipeline 35 with a circular spiral structure, which are connected in parallel in the main heat dissipation pipeline 31 through a multi-open joint 36, and the middle section pipeline is connected in series in the main heat dissipation pipeline 31 through a bent joint 37, and the branch heat dissipation pipeline 32 is connected in parallel in the main heat dissipation pipeline 31 through a three-way joint 38, so that the openings at both ends of the main heat dissipation pipeline 31 are the pipeline inlet and outlet of the heat absorption module 3, and the equipment housing 1 includes a main housing 11 and a front end cover 12, and the upper part of the front end cover 12 is respectively provided with a reserved hole 121 and a reserved hole 2 122, and the lower part of the front end cover 12 is provided with two reserved holes for cable entry and exit, and the reserved hole 121 on the front end cover 12 is provided with An air inlet connector 311 is installed and connected to the inlet of the main heat dissipation pipeline 31, a reserved hole 122 is set to install an air outlet connector 312 and connect to the outlet of the main heat dissipation pipeline 31, and two reserved holes at the lower part of the front cover 12 are set to install cable connectors for connecting external cables. Each connector is sealed with the edge of the opening to form a closed box. The fan 4 is installed on the front cover 12, and the air intake of the fan 4 is exposed to the environment, and the air outlet is connected to the air inlet connector 311. In this way, the heat generated by the electronic heating element in the box is transferred to the inner wall through the outer wall of the copper pipe, and the airflow generated by the fan 4 flows inside the pipe of the heat dissipation component 3, and discharges the heat absorbed from the inner wall of the pipe to the external environment, so as to achieve heat dissipation and cooling inside the closed box.
[0020] When the heat dissipation device in the closed box is working, the heat dissipation pipes placed in the box by the heat absorption module 3 conduct the heat energy in the box from the outer wall to the inner wall, and the capillary heat dissipation pipes 33 with irregular shapes that match the shape of the heating element 21 and fit and wind around it, the capillary heat dissipation pipes 34 with square spiral structures, and the capillary heat dissipation pipes 35 with circular spiral structures absorb the heat generated by the electronic device 2 when it is working. The airflow generated by the fan 4 flows through the heat dissipation pipes and absorbs heat from the inner wall and discharges it to the external environment, including the main heat dissipation pipe 31, the branch heat dissipation pipes 32 and the capillary heat dissipation pipes, which are connected in series or in parallel to an air inlet connected to the air inlet joint 311 and an air outlet connected to the air outlet interface 312. The fan 4 is started to draw the external air into the heat absorption module 3 through the air inlet joint 311 and divide it into various heat dissipation pipes, and finally discharge it to the external environment through the air outlet joint 312. In addition, the air inlet of the fan 4 is provided with a dustproof net, which blocks dust in the external air. This dustproof net is a prior art product and can be attached to the air inlet by gluing.
[0021] It should be noted that the front panel of the box is connected to the inlet and outlet of the internal copper tube through two sealing joints. The sealing performance of the sealing joints can prevent rainwater from flowing into the box from the opening of the front panel. Rainwater or air outside the box can only flow through the inner hole of the sealing joint into the copper tube inside the box. The copper tube wall completely isolates the water or air in the tube from the electronic devices in the box, thus protecting the internal circuit.
[0022] The box shell is sealed, and the opening of the front panel and the opening of the internal copper tube are connected with a sealed joint. It can be concluded that the outer wall of the box shell and the inner wall of the copper tube form a continuous space, which is the outside of a sealed container with a serious depression in a local position. The inner wall of the shell and the outer wall of the copper tube constitute the inside of this depressed sealed container, and the electronic devices are protected in it. The heat dissipation action is performed on the surface of the depressed area of this depressed sealed container. The air flowing through the inside of the pipe dissipates the heat on the surface of the depressed area of the container to the outside.
[0023] The copper tubes distributed in the box can be arranged as needed. The surface of the copper tube is the exchange interface between the heat in the box and the cold air inside the copper tube. The surface area of the copper tube is the size of the heat exchange interface, and the location of the copper tube is the main area of heat dissipation. The arrangement of the copper tube is very flexible, and the desired effect can be achieved through bifurcation and bending, such as capillary copper tubes wrapped around high-power heating devices, and large-diameter pipes distributed in the heating center. The fan inputs high-speed airflow to the pipe inlet, and discharges the heat absorbed by the pipe from the box from the pipe outlet, which effectively plays a waterproof role for the electronic devices in the box and achieves efficient heat dissipation inside the box.
