Description

Technical Field

[0001] This utility model belongs to the field of LED switching power supply technology, and specifically relates to a protective LED switching power supply. Background Technology

[0002] LED switching power supplies are power supplies that use circuits to control the switching transistors to perform high-speed conduction and interception, thereby maintaining a stable output voltage. They are used in high-tech fields and have advantages such as miniaturization and portability. Therefore, it is necessary to design a protective LED switching power supply.

[0003] Existing LED switching power supplies generate heat during operation due to the internal circuit board. Therefore, LED switching power supplies are made in the form of a mesh plate to achieve heat dissipation. However, the mesh plate shell structure is not waterproof. If an external water source is placed in the mesh plate shell, it can seep into the LED switching power supply through the through holes, causing damage to the internal components and affecting its lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a protective LED switching power supply with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A protective LED switching power supply includes a housing, on both sides of which are provided with openings and grooves extending into them. A circuit board that mates with the openings and grooves is inserted into the inner side of the housing. A heat dissipation component is fixedly installed at the bottom of the housing and placed directly below the circuit board. Both ends of the outer side of the housing are fixedly fitted with mounting sealing components that cover the heat dissipation components.

[0007] As a further optimization of this utility model, the heat dissipation assembly includes multiple heat dissipation fins fixedly installed at the bottom of the housing directly below the circuit board. A heat exchange tube is provided through the interior of the multiple heat dissipation fins. The heat dissipation assembly also includes a water tank fixedly installed at the bottom of the housing. A semiconductor cooling chip extending to the outside is installed at the bottom of the water tank. A mounting groove is provided at one end of the water tank. A water pump is fixedly installed inside the mounting groove. A connecting pipe connected to one end of the heat exchange tube is fixedly installed at the output end of the water pump.

[0008] As a further optimization of this utility model, the installation sealing assembly includes two sealing caps fitted onto both ends of the housing. One sealing cap has connecting rods fixedly installed on both sides of one end of its back side, which are placed inside the opening groove and inserted into the other sealing cap. Both sides of the two connecting rods are provided with multiple internal thread fixing grooves. Both sides of the other sealing cap are provided with fixing screws threaded through and cooperating with the internal thread fixing grooves.

[0009] As a further optimization of this utility model, the other sealing cover has grooves on both sides of one end of the front, and fixing screws are threaded through both sides of the two grooves, and the two grooves are fitted onto the outside of the connecting rod.

[0010] As a further optimization of this utility model, both ends of the two sealing covers are fixedly installed with fixing plates, and both sides of the interior of the two fixing plates are provided with internal threaded holes, which are matched with external bolts.

[0011] As a further optimization of this utility model, the heat exchange tube is made of an "S" shaped structure, and the end of the heat exchange tube away from the connecting pipe extends through the shell to the back end of the top of the water tank.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through its integrated shell structure design, eliminates the need for multiple heat dissipation mesh holes on its surface. Simultaneously, by cooperating with the sealing components and the shell sealing and fixing installation, it achieves a sealing function for the interior of the shell, thereby preventing external water from penetrating into its interior. This effectively reduces damage to the internal components of the LED switching power supply and extends its service life. Furthermore, the shell structure design and the use of the sealing components facilitate the fixing and installation of the circuit board, increasing the convenience and flexibility of the LED switching power supply's later installation and use.

[0014] 2. This utility model can achieve the cooling function inside the LED switching power supply through the structural design of the heat dissipation component. Compared with the traditional heat dissipation structure design with multiple through holes, this cooling efficiency is better and can effectively and timely achieve the cooling operation of the LED switching power supply. Moreover, through the "S"-shaped structure design of the heat exchange tube, the cooling time can be extended and the heat exchange function inside the shell can be achieved.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, a protective LED switching power supply includes a housing 1, which is formed by extrusion of a one-piece structure to facilitate the sealing performance of the housing exterior without the need for multiple heat dissipation holes. Opening grooves 4 are provided at the middle positions of both sides of the housing 1, extending to the inner side of the housing 1. The opening grooves 4 and the housing 1 are integrally extruded to form a single housing. A circuit board 5 is slidably placed inside the housing 1, with the bottom of the circuit board 5 fitting against the bottom of the inner side of the housing 1, and the two sides of the top of the circuit board 5 fitting against the bottom of the outer side of the opening grooves 4. This facilitates the positioning and placement of the circuit board 5. Furthermore, the design of the circuit board 5 and the connection design of the external wiring facilitate the control of the LED light source. A heat dissipation component 2 is fixedly installed at the bottom inside the housing 1 to cool the LED switching power supply. Both ends of the housing 1 are covered with matching mounting sealing components 3. The covering design of the mounting sealing components 3 securely mounts the circuit board 5 and also seals the interior of the housing 1 to prevent water penetration and ensure its service life.

[0023] like Figure 2 , Figure 3As shown, the heat dissipation assembly 2 includes a water tank 201 fixedly installed at the bottom of the housing 1. The structure of the water tank 201 facilitates the storage of chilled water. A thermoelectric cooler 200 is fixedly installed at the bottom of the water tank 201, with the heating end of the thermoelectric cooler 200 extending to the outside of the water tank 201 and the cooling end of the thermoelectric cooler 200 located at the bottom of the inner side of the water tank 201. The thermoelectric cooler 200 facilitates the cooling of the chilled water inside the water tank 201. The heat dissipation assembly 2 also includes multiple heat dissipation fins 206 fixedly installed at the bottom of the housing 1. The multiple heat dissipation fins 206 are vertically positioned directly below the bottom of the circuit board 5. The structure of the multiple heat dissipation fins 206 facilitates the conduction of heat generated by the circuit board 5 during operation. A heat exchange tube 205 is installed through the interior of the multiple heat dissipation fins 206. The heat exchange tube 205 is designed with an "S" shape and is placed inside the heat dissipation fins 206 to facilitate the heat exchange of heat inside the heat dissipation fins 206 through the chilled water inside the heat exchange tube 205. This allows for heat dissipation from the interior of the housing 1. One end of the heat exchange tube 205 extends through the interior of the housing 1 into and communicates with the interior of the water tank 201. A mounting groove 202 is provided on one end of the front of the water tank 201. A water pump 203 is fixedly installed at the bottom of the mounting groove 202. An inlet pipe is fixedly installed at the input end of the water pump 203, and the other end of the inlet pipe extends into and communicates with the interior of the water tank 201. A connecting pipe 204 is fixedly installed at the output end of the water pump 203, and the other end of the connecting pipe 204 is connected to... One end of the front of the top of the shell 1 is connected to the end of the heat exchange tube 205 away from the water tank 201. Later, the cold water inside the water tank 201 can be pumped into the connecting pipe 204 by the water pump 203, and then transferred to the heat exchange tube 205. Finally, the heat exchange work inside the shell 1 can be realized through the structural design of the heat exchange tube 205 and the heat dissipation fin 206. After the heat exchange is completed, it can be transferred to the water tank 201 through the heat exchange tube 205 to cool the hot water through the semiconductor cooling chip 200, thereby realizing the cyclic cooling work.

[0024] like Figure 1 , Figure 4As shown, the sealing assembly 3 includes two sealing covers 300 fixedly fitted at both ends of the housing 1. The two sealing covers 300 fit snugly against the outer ends of the housing 1, facilitating a sealing function to the interior of the housing 1 and preventing the penetration of external water. Each end of the two sealing covers 300 is fixed with a fixing plate. Both sides of the inner surface of the two fixing plates have internal threaded holes that mate with external bolts, facilitating the fixed installation of the housing 1 and its components. Each sealing cover 300 has a groove at the middle position on one side of its front end. A fixing screw 303 is threaded through the two grooves on opposite sides. The grooves facilitate the subsequent fixed installation of the two sealing covers 300, and the fixing screws 303 can then be used to secure the two sealing covers 300. For the other sealing cover 300, connecting rods 302 are fixedly installed at the middle positions of both sides on one end of the back. The back ends of the two connecting rods 302 are inserted into the inside of the groove. The two connecting rods 302 are located inside the two open grooves 4. The open grooves 4 facilitate the storage of the connecting rods 302. The back ends of the two connecting rods 302 on the opposite side are provided with multiple internal thread fixing grooves 301. The internal thread fixing grooves 301 cooperate with the fixing screws 303. The two sealing covers 300 are fixedly connected to the housing 1 by the threaded engagement of the fixing screws 303 and the internal thread fixing grooves 301. At the same time, the sealing covers 300 can seal the two ends of the housing 1 and also resist the two ends of the circuit board 5, thereby realizing the fixed installation of the circuit board 5.

[0025] It should be noted that, in the use of this type of protective LED switching power supply, the operator can first place the circuit board 5 inside the housing 1, and then place it at the bottom outside the opening groove 4. Figure 2 As shown, this allows for the placement of the circuit board 5 to be limited. Later, the water pump 203 can pump the cold water inside the water tank 201 into the connecting pipe 204, and then transfer it to the heat exchange pipe 205. At the same time, the heat dissipation fins 206 can conduct heat during the operation of the circuit board 5. Then, in conjunction with the coolant inside the heat exchange pipe 205, heat exchange is achieved inside the shell 1, thereby cooling the inside of the shell 1. After the heat exchange is completed, the heat exchange pipe 205 can transfer hot water back to the water tank 201, and then the semiconductor cooling chip 200 can cool the water inside the water tank 201, thereby achieving the cooling of the water circulation.

[0026] Later, the sealing caps 300 are removed and inserted into both ends of the housing 1. Then, by using the sealing caps 300 in conjunction with the housing 1, the circuit board 5 can be positioned and installed. At the same time, by fixing the two sets of sealing caps 300 together, the connecting rod 302 can be inserted into the groove. Then, the fixing screw 303 is screwed into the internal thread fixing groove 301, thereby fixing the two sealing caps 300 to complete the sealing of the exterior of the housing 1 and achieve its waterproof performance.

[0027] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
