Description

Technical Field

[0001] This utility model relates to the field of UVLED curing light source technology, specifically a UVLED curing light source cooling device. Background Technology

[0002] In high-power LED chips, the photoelectric conversion efficiency of UVLEDs is high, with approximately 60% or more of the electrical energy being converted into heat. This requires end-users to take good care of heat dissipation when using high-power UVLED curing products to ensure that the high-power UVLED chips can work normally.

[0003] In the prior art, Chinese utility model application number CN202021377429.X discloses a UVLED curing light source cooling device, including a side interface, a center connector, a mounting shell, a protective shell, a protective glass cover, a UVLED lamp group, a heat dissipation chamber, a front heat dissipation fan, an air duct, a heat dissipation copper pipe, and a rear heat dissipation fan. The side interface and the center connector are installed at the rear end of the mounting shell. The mounting shell and the protective shell are sealed together with screws. The front heat dissipation fan, the air duct, and the rear heat dissipation fan are installed in sequence inside the heat dissipation chamber. The heat dissipation copper pipe is installed at the front end of the air duct and directly contacts the UVLED lamp group panel. In this UVLED curing light source cooling device, a heat dissipation chamber is designed on the rear side of the UVLED curing light source module. The front heat dissipation fan transmits air to the rear heat dissipation fan through the air duct. The heat dissipation copper pipe is installed at the front end of the air duct and directly contacts the UVLED lamp group panel to remove heat. The air duct is designed to be wide at both ends and narrow in the middle to compress the air and increase the air flow rate. The diamond-shaped baffles inside the air duct improve the air convection speed and thus improve the heat dissipation efficiency.

[0004] Although the above technical solution utilizes the air velocity difference to dissipate heat from the lamp panel, the temperature reduction after the outside air is accelerated by entering the air duct is not significant. The cooling effect is poor in high-temperature weather, the overall heat exchange time is short, and the cooling efficiency of the light source needs to be further improved. Therefore, we need to propose a UVLED curing light source cooling device. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

A circulating pump circulates coolant from the coolant tank into a heat-absorbing copper pipe to exchange heat with the first heat exchange plate, thereby cooling the lamp assembly.

[0023] Please see Figure 1-5This utility model provides a technical solution: a UVLED curing light source cooling device, including a housing 1, a coolant tank 9 and a heat insulation plate 12 are provided in the inner cavity of the housing 1, a plurality of first heat exchange plates 13 are provided on one side of the heat insulation plate 12, a plurality of second heat exchange plates 14 are provided on the other side of the heat insulation plate 12, a heat exchange mechanism 11 is provided on the plurality of first heat exchange plates 13 and the plurality of second heat exchange plates 14, one side of the housing 1 is open, a lamp group 7 is provided in the inner cavity of the housing 1 near the open end, and the backlight side of the lamp group 7 abuts against the plurality of first heat exchange plates 13;

[0024] The heat exchange mechanism 11 includes a circulating pump 111, a heat-absorbing copper tube 113, and a heat-dissipating copper tube 115. The outlet end of the circulating pump 111 is provided with an inlet pipe 112 that is connected to the inlet end of the heat-absorbing copper tube 113. The outlet end of the heat-absorbing copper tube 113 is provided with a connecting pipe 114 that is connected to the inlet end of the heat-dissipating copper tube 115. The outlet end of the heat-dissipating copper tube 115 is provided with a return pipe 116 that is connected to the coolant tank 9. The heat-absorbing copper tube 113 is arranged on multiple sets of first heat exchange plates 13, and the heat-dissipating copper tube 115 is arranged on multiple sets of second heat exchange plates 14.

[0025] An air inlet channel 3 is provided on the side of the housing 1 adjacent to the lamp group 7. A cooling fan unit 5 is installed in the air inlet channel 3. A dustproof net 4 is installed at the air inlet end of the air inlet channel 3. Multiple sets of heat dissipation holes 8 are opened on the side of the housing 1 opposite to the air inlet channel 3. The cooling fan unit 5 provides air cooling to the second heat exchange plate 14 and the heat dissipation copper pipe 115, thereby improving the cooling efficiency of the coolant and improving the circulation effect of the coolant.

[0026] Multiple sets of first heat exchange plates 13 and multiple sets of second heat exchange plates 14 are arranged parallel to the horizontal plane and are equidistant from each other. The first heat exchange plates 13 and multiple sets of second heat exchange plates 14 improve the heat absorption effect, thereby improving the cooling efficiency of the lamp group 7 and the cooling effect of the coolant.

[0027] Both the heat-absorbing copper pipe 113 and the heat-dissipating copper pipe 115 are arranged in a serpentine shape and are staggered. By utilizing the shape of the heat-absorbing copper pipe 113 and the heat-dissipating copper pipe 115, the flow distance of the coolant is increased, thereby improving the heat dissipation effect on the lamp assembly 7 and the heat dissipation effect on the coolant.

[0028] Multiple sets of prismatic guide plates 10 are provided on one side of the coolant tank 9. An air guide channel is provided between two adjacent sets of prismatic guide plates 10. The air inlet and outlet sections of the air guide channel are larger than the middle section of the channel. The air blown out by the cooling fan unit 5 is compressed after passing through the air guide channel through the prismatic guide plates 10, and the air velocity is increased. The air guide channel improves the air velocity, thereby improving the heat dissipation efficiency.

[0029] A protective glass plate 6 for protecting the lamp assembly 7 is provided on one side of the housing 1. The protective glass plate 6 is made of tempered glass, which improves the protection effect of the lamp assembly 7.

[0030] A center connector 2 is provided on the side of the housing 1 opposite to the protective glass plate 6. The dustproof net 4 is a double-layer stainless steel mesh. Through the composite design of the dustproof net 4, the dust blocking effect is improved.

[0031] When the lamp assembly 7 is powered on, the circulating pump 111 and the cooling fan unit 5 start operating synchronously. The first heat exchange plate 13 directly contacts and removes the heat generated by the lamp assembly 7. The circulating pump 111 introduces coolant into the heat-absorbing copper pipe 113 through the water inlet pipe 112. The heat-absorbing copper pipe 113 removes the heat absorbed by the first heat exchange plate 13, thereby cooling the heat-absorbing copper pipe 113 through the flowing coolant, thus cooling the lamp assembly 7. The coolant that has absorbed heat flows back to the cooling copper pipe 115 through the connecting pipe 114. The cooling copper pipe 115 absorbs the heat from the cooling water and then the second heat exchange plate 14 absorbs the heat, thereby reducing the temperature of the coolant. At the same time, the cooling fan unit 5 increases the airflow speed inside the casing 1, thereby cooling the second heat exchange plate 14 through air cooling, further improving the heat dissipation efficiency of the cooling copper pipe 115, thus improving the cooling effect of the coolant. The cooled coolant then flows back to the coolant tank 9 for recycling, improving the cooling efficiency of the lamp assembly 7.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
