TECHNICAL FIELD
[0001] The utility model relates to electronic equipment technical field, concretely is a closed box internal heat conduction heat dissipation system. BACKGROUND
[0002] With the rapid development of modern electronic technology, high-power electronic products are increasingly widely used in various fields. During the operation of these electronic products, the internal electronic components, especially the electronic heating elements, will generate a large amount of heat energy. If these heat cannot be effectively dissipated in time, not only the performance stability of the electronic product will be affected, but also the equipment failure may be caused, and even the safety hazard may be triggered.
[0003] For the heat dissipation problem of the internal circuit board of the electric control box, there are mainly two solutions on the market. The first solution is to install a fan inside the box and open a hole on the shell so that cold air can flow through the circuit board to carry away heat. However, this solution has a significant disadvantage, that is, the open hole design cannot realize the outdoor waterproof function. In actual application, many electronic products need to be placed outdoors or in humid environments, and the open hole design will undoubtedly increase the risk of moisture intrusion, which threatens the normal operation of the electronic product.
[0004] Another solution is to place the circuit board in a completely sealed box and then install a fan outside the box to cool the box shell to achieve the heat dissipation effect of the internal components. Although this solution solves the waterproof problem, due to the large thermal resistance between the heating part and the box shell, the heat dissipation efficiency is extremely low. After a long time of operation, the temperature inside the box will continue to rise, which may eventually affect the service life and performance of the electronic product.
[0005] In view of the obvious shortcomings of the above two solutions, the industry urgently needs a closed box heat dissipation device that can effectively prevent water and efficiently dissipate heat. This device needs to be able to quickly remove the heat generated by the electronic heating elements while ensuring that the electronic product operates in a dry and safe environment, ensuring the stable operation of the electronic product.

DETAILED DESCRIPTION
[0027] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0028] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: a closed box internal heat conduction heat dissipation system, mainly including equipment shell 1, electronic equipment 2 and capillary heat absorption module 3.Equipment shell 1 is designed as closed structure, can effectively prevent the erosion of outside dust, moisture etc. to internal electronic equipment, simultaneously provide a relatively closed thermal environment, it is conducive to the operation of heat dissipation system, specific technical scheme is as follows:
[0029] The device shell 1 is composed of a main shell 11, a front end cover 12 and a rear end cover 13. The two ends of the main shell 11 are designed as open structures, and the front end cover 12 and the rear end cover 13 are respectively installed at the two ends of the main shell 11 to form a closed box structure, the electronic device 2 is installed inside the device shell 1, the capillary heat absorption module 3 is installed inside the device shell 1 and above the electronic device 2, the capillary heat absorption module 3 includes a main air duct pipeline and a plurality of capillary heat dissipation pipelines, each capillary heat dissipation pipeline is connected in series in the main air duct pipeline, and a spiral structure capable of winding or adhering outside the electronic heating element 21 is arranged in each capillary heat dissipation pipeline, the main air duct pipeline of the capillary heat absorption module 3 is responsible for absorbing heat energy inside the closed shell, the plurality of capillary heat dissipation pipelines are in contact with the heating electronic product to realize heat conduction, and then the heat conduction temperature is dispersed to the main air duct, and the heat energy of the pipe wall is sent out through the new air entering the heat absorption module 3
[0030] The upper part of the main shell 11 is reserved with an opening, and a window 111 is installed in the opening for observing the working state of the internal electronic device. The display screen 4 is installed at the top end of the inside of the main shell 11, and the display surface of the display screen 4 faces the window 111, which is convenient for users to check the device information. In addition, the upper part of the main shell 11 is provided with a handle 112, which is convenient for carrying and moving, and the upper part of the front end cover 12 is provided with a reserved hole one 121 and a reserved hole two 122 (which can be used to accommodate the air inlet connector 310 and the air outlet connector 311 respectively), and the lower part is symmetrically provided with a cable connector, through which the external cable can be connected with the wiring terminal of the electronic device 2;
[0031] The electronic device 2 is installed inside the device shell 1, and a plurality of electronic heating elements 21 are installed on the upper part of the electronic device 2. These heating elements are the main target of the heat dissipation system;
[0032] The capillary heat absorption module 3 includes an air inlet pipeline 31, an air outlet pipeline 32, a U-shaped connecting pipeline 33, a plurality of shunt pipelines 37, and a plurality of capillary pipelines 34. The air inlet pipeline 31 and the air outlet pipeline 32 are respectively used as the inlet and outlet of the cooling air, and are connected in series through the U-shaped connecting pipeline 33 and the shunt pipeline 37 to form a main air duct pipeline. The capillary pipeline 34 is connected in series in the main air duct pipeline to enhance the heat dissipation effect. The air inlet pipeline 31, the air outlet pipeline 32, the U-shaped connecting pipeline 33, the shunt pipeline 37, and the capillary pipeline 34 are all made of copper pipes because copper has good heat conduction performance and can effectively transfer heat. The diameter of each capillary pipeline 34 is smaller than that of the other pipelines to reduce air resistance and increase the heat dissipation area. A spiral wrapping body 35 is arranged in the section of the capillary pipeline 34. The spiral wrapping body 35 wraps the outside of the electronic heat generating element 21, and its shape is adapted to the shape of the electronic heat generating element 21 and closely fits to maximize the heat dissipation effect. The air inlet ends and the air outlet ends of the plurality of capillary pipelines 34 are connected in series through a capillary pipeline collection joint 36. The U-shaped connecting pipeline 33, the shunt pipeline 37, and the capillary pipeline collection joint 36 are connected in series through a three-way joint 38 with the air inlet pipeline 31 and the air outlet pipeline 32 to form a complete heat dissipation system. The fan 39 is installed on the front of the equipment shell 1, and its air inlet is exposed to the environment. The air outlet of the fan 39 is connected in series with the air inlet end of the air inlet pipeline 31 through an air inlet joint 310. The air outlet end of the air outlet pipeline 32 is connected with an air outlet joint 311, and the air outlet end of the air outlet joint 311 extends to the outside of the equipment shell 1 to discharge hot air.
[0033] When the closed box heat dissipation device is working, the plurality of electronic heat generating elements 21 of the electronic device 2 will generate a large amount of heat energy when working. The fan 39 is started, and the fan 39 draws the external air into the air inlet pipeline 31, and then the air is shunted to the plurality of capillary pipelines 34 from the air inlet pipeline 31. When the air flow passes through the spiral wrapping body 35 in the capillary pipeline 34, because the spiral wrapping body 35 is closely fitted with the electronic heat generating element 21, the heat generated by the electronic heat generating element 21 will be transferred to the spiral wrapping body 35, the entire capillary pipeline 34, and the air inlet pipeline 31 and the air outlet pipeline 32 (because the air inlet pipeline 31 and the air outlet pipeline 32 are far away from the heat source, so the heat is mainly concentrated on the spiral wrapping body 35 and the capillary pipeline 34). The air flow will take away the heat of the spiral wrapping body 35 and the capillary pipeline 34, and discharge the heat through the air outlet pipeline 32;
[0034] In the process of taking away heat, because the diameter of the capillary tube 34 and the spiral ring body 35 is much smaller than the diameter of the air inlet pipe 31 and the air outlet pipe 32, when the airflow enters the inside of the capillary tube 34 from the air inlet pipe 31, it will show a positive pressure at the joint of the air inlet pipe 31 and the capillary tube 34, and because it is also connected with the U-shaped connecting pipe 33 and the several branch pipes 37, most of the airflow will flow into the air outlet pipe 32 through the U-shaped connecting pipe 33 and the branch pipes 37 (that is, not along the path of the capillary tube 34 and the spiral ring body 35), so the flow rate in the air outlet pipe 32 is much larger than that in the capillary tube 34, thus showing a negative pressure at the joint of the capillary tube 34 and the air outlet pipe 32. In this way, the air inlet and air outlet of the capillary tube 34 are positive pressure and negative pressure respectively, that is, positive pressure injection and negative pressure suction, which will instantaneously increase the flow rate in the capillary tube 34, so that the heat generated by the electronic heating element 21 can be quickly taken away.
