Description

Technical Field

[0001] The utility model discloses a water-cooling and air-cooling composite mechanism, belonging to the field of UVLED lamp board heat dissipation equipment. Background Art

[0002] During the operation, the UVLED lamp board will output high energy and high density, thus generating a large amount of heat, which will increase the temperature of the chip inside the UVLED lamp board. If the chip temperature is higher than 70 degrees Celsius, it will cause huge thermal attenuation. At the same time, the increase in power supply temperature will make the power output unstable. The water-cooled platform is prone to condensation due to thermal inertia.

[0003] In the prior art, a water cooling mechanism is installed on the back of the UVLED lamp board to continuously cool the chip inside the lamp board with water, thereby ensuring that the UVLED lamp board chip does not suffer from thermal attenuation while ensuring stable power output. However, long-term operation of the water-cooled heat dissipation platform will cause condensation on the back of the water cooling platform and the UVLED lamp board due to thermal inertia, making the UVLED lamp board prone to electrical failures and reducing the heat dissipation reliability.

[0004] In summary, the present invention provides a water-cooling and air-cooling composite mechanism to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a water-cooling and air-cooling composite mechanism to solve the problem in the above background technology that water-cooling heat dissipation is prone to condensation, causing LED lamp failure.

[0007] Furthermore, the top and bottom of the two card seats are both protruded backwards and extend to the top and bottom of the mounting plate respectively, and the top and bottom of the two card seats are fixedly connected to the top and bottom of the mounting plate by screws.

[0008] Furthermore, the top and bottom of the front side of the mounting plate are provided with slots for engaging with two sockets, and the ends of the two slots away from the water-cooled heat exchanger extend to one side of the mounting plate.

[0009] Furthermore, the top and bottom of the front sides of the two card seats are both in the shape of raised card blocks, and the back sides of the two connecting plates are both provided with card slots that cooperate with the raised blocks on the top and bottom of the front sides of the card seats.

[0010] Furthermore, the LED lamp board is electrically connected to the LED lamp power supply through a wire, and the air outlet of the cooling fan faces the back of the LED lamp board and the heat exchange exhaust pipe.

[0011] Furthermore, the heat exchange exhaust pipe is in the shape of multiple rows of "U"-shaped bends, and the three sections of "U"-shaped bends of the heat exchange exhaust pipe are respectively clamped into the three inner grooves on the front side of the clamping seat.

[0012] Furthermore, the two mounting grooves are in a square concave shape, and the number of fans in each row of heat dissipation fans is five.

[0013] Beneficial effects of the utility model:

The heat energy on the LED light board can be continuously absorbed by the heat exchange pipe, and the heat energy is adsorbed and taken away by the condensing medium and then continuously cooled by the water-cooled heat exchanger, so that the LED light board can be continuously circulated and cooled.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See also Figure 1-5The utility model provides a technical solution: a water-cooled and air-cooled composite mechanism, including a mounting plate 1, a water-cooled heat exchanger 2, an LED light board 5 and an LED light power supply 8. The water-cooled heat exchanger 2 is fixedly connected to one side of the mounting plate 1. A card holder 3 is clamped between the top and the bottom of both sides of the front of the mounting plate 1. The fronts of the two card holders 3 are evenly provided with three inner grooves 6 from top to bottom. A heat exchange exhaust pipe 10 is connected between the water inlet and the water outlet of the water-cooled heat exchanger 2 and between the inner grooves 6 located on the front of the two card holders 3. A connecting plate 4 is clamped between the tops of the two front sides of the card holders 3 and between the bottoms of the two front sides of the card holders 3. The LED light board 5 is fixedly connected between the opposite sides of the two connecting plates 4 and Located on the front side of the heat exchanger exhaust pipe 10, the LED lamp power supply 8 is fixedly connected to the back side of the mounting plate 1 by screws, and mounting grooves 7 are provided on the back sides of the two sockets 3. Three rows of cooling fans 9 are evenly fixedly connected from top to bottom on the front side of the mounting plate 1 and between the mounting grooves 7 on the back sides of the two sockets 3. Since a low-temperature heat dissipation space is formed between the front side of the mounting plate 1 and the back side of the LED lamp board 5 through the water-cooled heat exchanger 2, the heat exchanger exhaust pipe 10 and the cooling fan 9, the mounting plate 1 can absorb heat and transfer heat at the same time. The LED lamp power supply 8 can be protected from heat dissipation by the cooled mounting plate 1, which effectively expands the heat dissipation protection range of the water-cooled and air-cooled composite mechanism and improves the working stability of the LED lamp.

[0026] See also Figure 1-4 The top and bottom of the two card seats 3 are both protruding backwards and extend to the top and bottom of the mounting plate 1 respectively. The top and bottom of the two card seats 3 are fixedly connected to the top and bottom of the mounting plate 1 by screws. The top and bottom of the front of the mounting plate 1 are provided with card slots for matching the two card seats 3, and the ends of the two card slots away from the water-cooled heat exchanger 2 extend to one side of the mounting plate 1. The water-cooled heat exchanger 2 is connected to an external power supply and is provided with a power control switch. The working principle of the water-cooled heat exchanger 2 is to achieve heat balance by transferring heat between the cooling medium and the heat source medium. The heat source medium passes through one side of the water-cooled heat exchanger 2 and releases heat on the metal surface in contact with the cooling medium. Then the cooling medium flows through the pipe on the other side to take away the heat.

[0027] See also Figure 2-4 The top and bottom of the front sides of the two card holders 3 are both in the shape of raised card blocks, and the back sides of the two connecting plates 4 are provided with card slots that match the raised blocks on the top and bottom of the front sides of the card holders 3. The LED light board 5 is electrically connected to the LED light power supply 8 through wires, and the air outlet of the cooling fan 9 faces the back side of the LED light board 5 and the heat exchange exhaust pipe 10. The heat exchange exhaust pipe 10 is in the shape of multiple rows of "U"-shaped curved pipes, and the three sections of "U"-shaped curved pipes of the heat exchange exhaust pipe 10 are respectively clamped into the three inner grooves 6 on the front side of the card holder 3. The heat exchange exhaust pipe 10 can be stably supported by the inner grooves 6 on the two card holders 3 to ensure the stability of the water-cooled heat exchange operation.

[0028] See also Figure 2-3 The two mounting grooves 7 are square depressions. Each row of cooling fans 9 has five fans. Each row of cooling fans 9 is connected to an external power supply and is provided with the same power control switch. By starting the water-cooled heat exchanger 2, the condensing medium inside the heat exchange pipe 10 can be circulated and pumped for circulation cooling. The heat exchange pipe 10 can continuously absorb the heat energy on the LED light board 5, and the heat energy is adsorbed and taken away by the condensing medium and then continuously cooled by the water-cooled heat exchanger 2, so that the LED light board 5 can be continuously circulated and cooled. At the same time, multiple rows of cooling fans 9 are started, and the cold air blown by the cooling fans 9 is evenly blown to the LED light board 5 and the pipe surface of the heat exchange pipe 10 to prevent condensation caused by excessive water cooling, avoid electrical failures caused by condensation, and effectively improve the heat dissipation reliability.

[0029] Specific implementation method: By starting the water-cooled heat exchanger 2, the condensing medium inside the heat exchange exhaust pipe 10 can be circulated and pumped for circulation cooling. The heat energy on the LED light board 5 can be continuously absorbed by the heat exchange exhaust pipe 10, and the heat energy is adsorbed and taken away by the condensing medium and then continuously cooled by the water-cooled heat exchanger 2, so that the LED light board 5 can be continuously circulated and cooled. At the same time, multiple rows of cooling fans 9 are started, and the cold air blown by the cooling fans 9 is evenly blown to the LED light board 5 and the tube surface of the heat exchange exhaust pipe 10 to prevent condensation due to excessive water cooling, avoid electrical failures caused by condensation, and effectively improve the heat dissipation reliability.

[0030] Since a low-temperature heat dissipation space is formed between the front of the mounting plate 1 and the back of the LED lamp board 5 through the water-cooled heat exchanger 2, the heat exchange exhaust pipe 10 and the cooling fan 9, the mounting plate 1 can absorb heat and transfer heat at the same time. The cooling mounting plate 1 can also provide heat dissipation protection for the LED lamp power supply 8 at the same time, effectively expanding the heat dissipation protection range of the water-cooled and air-cooled composite structure and improving the working stability of the LED lamp.

[0031] The inner grooves 6 on the two holders 3 can stably support the heat exchange pipes 10 to ensure the stability of the water-cooling heat exchange operation.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
