The suspension design ensures the stable output of the internal antenna signal of the product. The glue filling area is not easy to produce bubbles, and the glue filling is relatively uniform, which can make the electronic components generate heat for a long time. The service life of the overall product is prolonged. At the same time, the sealing ring can assist in waterproofing, moisture-proofing and high-low temperature-proofing, so that the controller box is suitable for different voltage environments and has high precision, so as to solve the problems that the existing AGV control box is directly connected with the control box through four locking screws, and then glue is filled, which is not conducive to the installation of the control panel by workers, and the positioning is not accurate during installation, and the waterproofness of the control box is poor.

Moreover, in the following description, the description of known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0027] As Figures 1-4As shown, the utility model provides a kind of internal self-heat dissipation structure of pushing material AGV navigation controller, including navigation controller body 1, navigation controller body 1 both sides surface are all provided with heat dissipation mounting groove 2, heat dissipation mounting groove 2 is symmetrically arranged, the inner wall of heat dissipation mounting groove 2 is all through and is provided with heat conduction jack 3, the inner cavity of heat conduction jack 3 is all through and is inserted with heat conduction column 4, one end surface of heat conduction column 4 is connected with outer heat conduction plate 5, the other end surface of heat conduction column 4 is connected with inner heat conduction plate 7, and outer heat conduction plate 5 surface is equipped with semiconductor refrigeration piece 6;

[0028] The inner heat conduction plate 7 is equipped with a circulating fan 8 on the surface.

[0029] It should be noted that when the semiconductor refrigeration piece 6 is coupled into a galvanic couple by a piece of N-type semiconductor material and a piece of P-type semiconductor material, a transfer of energy can be generated in this circuit after a direct current is connected, and the current is absorbed by the joint of the N-type element to the P-type element, becoming a cold end, and the joint of the P-type element to the N-type element releases heat, becoming a hot end. The cold energy is transmitted to the outer heat conduction plate 5 through the heat-conducting silicone grease, and the outer heat conduction plate 5 transmits the cold energy to the inner heat conduction plate 7 through the heat conduction column 4. The circulating fan 8 can accelerate the air flow rate on the surface of the inner heat conduction plate 7, so that the cold energy on the inner heat conduction plate 7 can be quickly released into the inner cavity of the navigation controller body 1. Through the continuous circulation of cold energy in the inner cavity of the navigation controller body 1, rapid heat dissipation and cooling of the inner cavity of the navigation controller body 1 can be achieved.

[0030] In this embodiment, as shown in the figure, Figure 3 The outer heat conduction plate 5 is located in the heat dissipation mounting groove 2, and the surface of the outer heat conduction plate 5 is connected to the surface of the semiconductor refrigeration piece 6 with heat-conducting silicone grease.

[0031] It should be noted that the heat-conducting silicone grease can improve the conduction effect of cold energy.

[0032] In this embodiment, as shown in the figure, Figure 3 The inner heat conduction plate 7 is located in the inner cavity of the navigation controller body 1, and the inner heat conduction plate 7 is a double-plate structure.

[0033] It should be noted that the double-plate structure of the inner heat conduction plate 7 can improve the conduction effect of cold energy.

[0034] In this embodiment, as shown in the figure, Figure 3 The surface of the heating surface of the semiconductor refrigeration piece 6 is equipped with a heat dissipation fin 9, the surface of the heat dissipation fin 9 is equipped with a heat dissipation fan 10, and the heat dissipation fan 10 is symmetrically arranged.

[0035] It should be noted that the circulating fan 8 can accelerate the air flow rate on the surface of the inner heat conduction plate 7, so that the cold energy on the inner heat conduction plate 7 can be quickly released into the inner cavity of the navigation controller body 1.

[0036] In this embodiment, as Figure 3 As shown, a desiccant plate 13 is movably provided on the surface of the circulating fan 8, and a drying box 11 is installed on the surface of the inner heat-conducting plate 7. The circulating fan 8 is located between the inner heat-conducting plate 7 and the drying box 11. An insertion interface 12 is provided at one end of the drying box 11, and the desiccant plate 13 is movably inserted into the inner cavity of the drying box 11 through the insertion interface 12.

[0037] It should be noted that the desiccant plate 13 is movably inserted into the inner cavity of the drying box 11 via the insertion interface 12, which makes it easy to replace the desiccant plate 13.

Ventilation holes 14 are provided on the surfaces of both the desiccant plate 13 and the drying box 11.

[0039] It should be noted that the sealing ring 15 can seal the connection between the insertion interface 12 and the desiccant plate 13 to prevent moisture leakage and improve the drying effect of the airflow. Moisture can pass through the vent hole 14 through the desiccant plate 13 and the drying box 11.

[0040] The working principle and usage of this utility model are as follows: The semiconductor cooling chip 6 is electrically connected to the heat dissipation fan of the navigation controller body 1. When the semiconductor cooling chip 6 is composed of an N-type semiconductor material and a P-type semiconductor material connected to form an electrical couple, energy transfer occurs when a DC current is applied to this circuit. The current flows from the N-type element to the P-type element's junction, absorbing heat and becoming the cold end. The current flows from the P-type element to the N-type element's junction, releasing heat and becoming the hot end. The cold end transfers the cooling energy to the outer heat-conducting plate 5 through thermal grease. The outer heat-conducting plate 5 transfers the cooling energy to the inner heat-conducting plate 7 through the thermally conductive pillars 4. The circulating fan 8 can accelerate the airflow speed on the surface of the inner heat-conducting plate 7, thereby enabling the inner heat-conducting plate 7 to cool down. The cold air on the hot plate 7 is quickly released into the inner cavity of the navigation controller body 1. The cold air circulates continuously in the inner cavity of the navigation controller body 1, which can achieve rapid heat dissipation and cooling inside the navigation controller body 1. The hot end of the semiconductor cooling chip 6 transfers heat to the heat dissipation fins 9. The heat dissipation fins 9 and the cooling fan 10 are used together to achieve rapid cooling of the hot end of the semiconductor cooling chip 6, so as to ensure the stability of the operation of the semiconductor cooling chip 6. The cold air blown out by the circulating fan 8 enters the drying box 11 through the vent 14 and passes through the desiccant plate 13. The desiccant plate 13 can absorb the moisture in the air through the desiccant powder inside, so as to ensure the dryness inside the navigation controller body 1.
