Technical Field
[0001] The present invention relates to the technical field of relays, and specifically to a relay heat dissipation component. Background Art
[0002] A relay is an electrical control device. When the change of the input quantity (excitation quantity) reaches the specified requirement, a predetermined step change occurs in the controlled quantity in the electrical output circuit. It has an interactive relationship between a control system (also called an input circuit) and a controlled system (also called an output circuit). Its main types include electromagnetic relays, solid-state relays, and thermal dry reed relays. Among them, an electromagnetic relay is composed of an iron core, a coil, an armature, contact reeds, etc. When a certain voltage is applied across the coil, an electric current flows through the coil to generate an electromagnetic effect. The armature is attracted by the electromagnetic force and overcomes the pulling force of the return spring to be attracted to the iron core, driving the moving contact to engage with the normally open static contact; after the coil is powered off, the electromagnetic attraction disappears, and the armature returns under the reaction force of the spring, and the moving contact engages with the normally closed static contact, thereby realizing the conduction and cut-off of the circuit. During the use of an electromagnetic relay, the coil inside generates heat when energized. If this heat cannot be dissipated in time, it will cause the temperature inside the relay to be too high, melting the insulation layer of the coil, short-circuiting or even burning the relay, causing danger.
[0003] However, most of the existing relay heat dissipation structures are arranged outside the relay and cannot guide and dissipate the heat inside the relay in time, resulting in low heat dissipation efficiency. To solve the above problems, we propose a relay heat dissipation component to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The technical solution in the embodiment of the present application is to solve the problems in the above-mentioned background technology. The general idea is as follows: By installing components such as heat conduction columns 4, heat conduction plates 5, heat conduction fins 7 and heat dissipation fins 8 inside the relay housing 1, the heat inside the relay can be transferred to the outside for heat dissipation and temperature reduction. In addition, the setting of the heat dissipation channel 10 in the present invention, and by providing an air cooling component and a spraying component, the present invention can enable corresponding heat dissipation and temperature reduction solutions according to the operating state of the relay, so as to efficiently dissipate heat and cool down the relay, and enhance the safety of the relay during use.
[0018] Embodiment: Refer to Figure 1 - Figure 3As shown in the figure, a relay heat dissipation component of this embodiment includes a relay housing 1, a core column 2 installed inside the relay housing 1, and a coil 3 wound around the periphery of the core column 2; a heat conducting sheet 7 is arranged on the periphery of the coil 3, a heat conducting column 4 is arranged in the middle of the inner side of the core column 2, heat conducting plates 5 are arranged at both ends of the heat conducting column 4, and the heat conducting plates 5 are connected to the heat conducting sheet 7. Through the heat conducting column 4, the heat inside the core column 2 can be transferred outward, enhancing the uniformity and efficiency of heat dissipation.
[0019] Heat dissipation components are arranged at both ends of the heat conducting sheet 7, including an air cooling component and a spraying component; The air cooling component includes multiple groups of heat dissipation fins 8. The multiple groups of heat dissipation fins 8 are installed at the bottom of both ends of the heat conducting sheet 7. Heat dissipation channels 10 are arranged at the bottom of both ends of the relay housing 1. The outer sides of the heat dissipation fins 8 extend out of the relay housing 1 and are installed in the heat dissipation channels 10. A heat dissipation fan 12 is arranged at the inlet end of the heat dissipation channel 10. The arrangement of the heat dissipation channel 10 makes the wind blown by the heat dissipation fan 12 more concentrated, thereby enhancing the efficiency of heat dissipation by the heat dissipation fins 8 through blowing.
[0020] The spraying component includes a spraying pipe 18. Multiple groups of spray heads are installed at equal intervals at the bottom of the spraying pipe 18. The spraying pipe 18 is installed at the inner top of the heat dissipation channel 10. Butterfly valves 13 are arranged in the middle of both ends of the heat dissipation channel 10. The spraying pipe 18 is connected to a water tank 14 through a pipeline 16. Under the action of a water pump, the cooling water stored in the water tank 14 can be transported to the spraying pipe 18 for spraying, thereby realizing spraying and cooling of the heat dissipation fins 8 and enhancing the effect of heat dissipation and cooling.
[0021] The middle part of the inner side of the heat dissipation channel 10 is set as a square structure channel, and both ends of the heat dissipation channel 10 are set as cylindrical structures 11. The heat dissipation fan 12 is installed in the middle of the inner side of the cylindrical structure 11 at the inlet end. Two groups of butterfly valves 13 are respectively installed in the cylindrical structures 11 at both ends. By closing the butterfly valves 13, the inside of the heat dissipation channel 10 is in a sealed state, so that the spraying pipe 18 in the spraying component can spray cooling water to cool the heat dissipation fins 8. Even, the cooling water can be stored in the heat dissipation channel 10 to soak the heat dissipation fins 8, further enhancing the effect of heat dissipation and cooling; on the contrary, when the butterfly valves 13 are in the open state, both ends of the heat dissipation channel 10 are in a ventilated state, facilitating the heat dissipation fan 12 to blow air into the inside, so that the heat flows out from the outlet end of the heat dissipation channel 10.
[0022] In some examples, multiple groups of water leakage holes 9 are opened in the middle of the multiple groups of heat dissipation fins 8, and the positions of the water leakage holes 9 of the upper layer of heat dissipation fins 8 and the lower layer of heat dissipation fins 8 are staggered, so that the cooling water can flow to each heat dissipation fin 8, increasing the contact time between the cooling water and the heat dissipation fins 8, thereby enhancing the efficiency of the cooling water taking away the heat of the heat dissipation fins 8.
[0023] In some examples, the water tank 14 is located at the bottom of the relay housing 1. A water outlet pipe 15 is provided in the middle of the bottom end of the water tank 14, and a water pump is provided at the water outlet pipe 15, which is mainly used for conveying cooling water. An inlet pipe 17 is provided at the top of the heat dissipation channel 10, and the inlet pipe 17 and the water outlet pipe 15 are connected by a pipeline 16.
[0024] In some examples, heat-conducting silica gel 6 is filled between the coil 3 and the heat-conducting fin 7.
[0025] In some examples, a water return pipe 19 is provided in the middle of the bottom end of the heat dissipation channel 10, and the end of the water return pipe 19 is located at the top of the water tank 14. Through the water return pipe 19, the cooling water in the heat dissipation channel 10 can be guided into the water tank 14 for heat exchange.
[0026] Under the action of the water outlet pipe 15, the pipeline 16, the inlet pipe 17, the spray pipe 18 and the water return pipe 19, the cooling water forms a cycle, playing a role in circulating heat exchange.
[0027] In some examples, valves are provided in the middle of both the inlet pipe 17 and the water return pipe 19. When the spray assembly is in the open state, the valves are opened, and when the spray assembly is in the closed state, the valves are closed.
[0028] In some examples, the spray pipe 18 is located in the middle of the upper end of the heat dissipation fins 8 and has the same length as the heat dissipation fins 8. Through the spray pipe 18, the cooling water can be sprayed onto the upper-layer heat dissipation fins 8, and then under the flow of the water leakage holes 9, the cooling water can flow from the upper-layer heat dissipation fins 8 to the lower-layer heat dissipation fins 8 in sequence, enabling the cooling water to come into full contact with the heat dissipation fins 8. During the flow of the cooling water, the heat on the heat dissipation fins 8 can be driven, thereby enhancing the efficiency of heat dissipation and cooling.
[0029] The working principle of the present invention is: In the present invention, by providing an air-cooling component and a spray component, efficient intelligent heat dissipation of the relay is achieved. When the usage power of the relay is relatively low, at this time, the heat generated by the relay can be air-cooled by the air-cooling component. When the relay operates at high power, at this time, the air-cooling component is turned off and the spray component is started, thereby improving the efficiency of heat dissipation and cooling. By providing a relay heat dissipation component, the present invention enables corresponding heat dissipation and cooling solutions to be turned on according to the operating state of the relay, achieving intelligent heat dissipation of the relay, thereby effectively avoiding the disadvantages of waste of energy consumption caused by insufficient heat dissipation or excessive heat dissipation power.
[0030] The main heat dissipation process is as follows: during the operation of the relay, the coil 3 will generate heat. At this time, a heat-conducting sheet 7 and a heat-conducting silica gel 6 are installed on the periphery of the coil 3. First, the heat of the coil 3 can be transferred to the heat-conducting sheet 7 through the heat-conducting silica gel 6. In addition, a heat-conducting column 4 is arranged in the middle of the inner side of the core column 2, and heat-conducting plates 5 are arranged at both ends of the heat-conducting column 4. The heat-conducting plates 5 are connected to the heat-conducting sheet 7. The heat in the core column 2 can also be transferred to the heat-conducting sheet 7 through the heat-conducting column 4 and the heat-conducting plate 5. Since heat-dissipating fins 8 are arranged at the bottom of both ends of the heat-conducting sheet 7, the heat inside the relay can be transferred to the outside through the heat-dissipating fins 8, thereby playing a role in heat dissipation and cooling. At the same time, by providing a cooling fan 12 at the inlet end of the cooling channel 10, starting the cooling fan 12 can blow air to the cooling fins 8, further improving the efficiency of the cooling of the cooling fins 8; In addition, when the relay is in high-power operation, the air cooling component is not enough to quickly cool down and dissipate heat, then the air cooling component is turned off, and the spray component is turned on for cooling. First, the cooling fan 12 is turned off, and the butterfly valves 13 at both ends of the heat dissipation channel 10 are started at the same time. The vents at both ends of the heat dissipation channel 10 are closed by closing the butterfly valve 13, so that the heat dissipation channel 10 is in a sealed state, and then the water pump inside the water tank 14 is started, and the coolant stored in the water tank 14 is transported to the spray pipe 18 through the outlet pipe 15, the pipe 16 and the inlet pipe 17, so that the cooling water is sprayed from the top layer of the heat dissipation fins 8 for cooling. The cooling water flows on the heat dissipation fins 8 to drive the flow of heat, and finally flows back to the water tank 14 through the return pipe 19 at the bottom of the heat dissipation channel 10 for heat exchange. In the above process, the heat dissipation and cooling efficiency of the heat dissipation fins 8 can be enhanced by spraying cooling water; If the efficiency of spray cooling is insufficient, the valve at the return pipe 19 can be adjusted to reduce the return water flow rate so that the cooling water can accumulate in the heat dissipation channel 10 to soak the heat dissipation fins 8, further enhancing the efficiency of cooling the heat dissipation fins 8.
[0031] With the cooperation of the temperature sensor, the present invention can realize flexible switching of the operation between the air-cooling component and the spray component. Compared with the traditional technology of using only air cooling or water cooling, it is easy to have insufficient efficiency or excessive energy consumption during use. For example, some large relays have too high power. When running at high power, it is difficult to quickly cool them down by only air cooling. If water cooling is installed, once the relay is in low power operation, its water cooling will waste energy. In the present invention, the setting of the heat dissipation channel 10, in conjunction with the switching of the air-cooling component and the spray component, enables intelligent heat dissipation of the relay, thereby effectively avoiding the disadvantages of energy waste caused by insufficient heat dissipation or excessive heat dissipation power.
