[0030] In the UV lamp curing process, the UV lamp needs to be kept at a certain temperature, and the long-term operation of the UV lamp will inevitably cause the temperature to rise. In order to achieve constant temperature, it is generally necessary to add a cooling system to cool it down. In the prior art, circulating nitrogen is generally used. The nitrogen passes through the UV lamp and is sucked to the heat exchanger along the reflux channel. After cooling, it is sent to the UV lamp again. This cycle is repeated to achieve cooling treatment, but the existing cooling method is not ideal. In order to solve the above problems, this embodiment discloses a cooling mechanism 100 used in a gas reflux system.

[0031] See also Figures 1 to 4 In this first embodiment, this embodiment discloses a cooling mechanism 100 applied to a gas reflux system. The cooling mechanism 100 of the gas reflux system is used in scenes such as UV lamps that require fast and precise control, and includes: a coolant circulation pipe 11 and a heat sink group 13; a circulation lumen is provided in the coolant reflux pipe 11, and the heat sink group 13 is arranged in the circulation lumen, and the heat sink group 13 is arranged near one end of the air outlet of the coolant circulation pipe 11.

[0032] In this embodiment, the coolant circulation pipe 11 is used to provide a circulation channel for the gas coolant, and it occupies a certain space. In the prior art, a coolant (such as nitrogen, etc.) is introduced into the coolant circulation pipe 11, and a fan is used to pump the nitrogen in the coolant circulation pipe 11, so that it passes through the components that need to dissipate heat and the heat exchanger in turn, so as to circulate, thereby quickly dissipating heat from the heat-generating components and maintaining a relatively constant temperature state. The existing cooling system only uses a heat exchanger to cool the coolant, and the processing efficiency is low, which does not meet the needs of scenes such as UV lamps that require rapid temperature control.

[0033] In order to improve the heat dissipation effect of the coolant during the circulation and reflux cooling process, this embodiment adds a heat sink group 13 in the coolant circulation pipe 11. The heat sink group 13 absorbs the heat of the coolant and quickly transfers it to the pipe wall of the coolant circulation pipe 11, and finally releases it into the environment, thereby further improving the heat dissipation effect.

[0034] Specifically, the heat sink group 13 includes a plurality of heat sinks 131 extending along the coolant flow direction, and cooling gaps are reserved between adjacent heat sinks 131, and the cooling gaps are connected to one end of the air outlet 1121. Figure 4 As shown, a plurality of heat sinks 131 can be arranged horizontally in layers, or arranged vertically in a front-to-back arrangement, or arranged in a front-to-back arrangement in an inclined manner, and the cooling gaps between adjacent heat sinks 131 are used to circulate the coolant. It should be noted that the edges of the plurality of heat sinks 131 abut against the wall of the coolant circulation pipe 11. The heat sink 131 is made of a material with good thermal conductivity, such as aluminum or copper sheets.

[0035] In this embodiment, a plurality of the heat sinks 131 are arranged at equal intervals. The heat sink 131 may be a planar sheet structure or other non-planar sheet structure, and the surface of the heat sink 131 may be a smooth surface or a non-smooth surface. However, a cooling channel for coolant circulation must be reserved between adjacent heat sinks 131. The heat sink 131 may also adopt a honeycomb structure or other structure that can expand the heat dissipation contact area.

[0036] In this embodiment, the coolant circulation pipe 11 includes: a vertical pipe portion 111 and a horizontal pipe portion 112 connected to the upper end of the vertical pipe portion 111, and the heat sink group 13 is arranged in the tube cavity of the horizontal pipe portion 112. The horizontal pipe portion 112 is perpendicular to the vertical pipe portion 111. In other embodiments, the shape and structure of the coolant circulation pipe 11 are set according to the needs of the actual application scenario, and are not limited to the shape of this embodiment. Its main purpose is to guide the hot air to be passed through the heat dissipation component back to the heat dissipation component, so as to complete the circulation cooling process.

[0037] A coolant air inlet 1111 is also provided at the bottom of the vertical pipe portion 111, which is used to be an output end of the coolant gas of an external cooling component, such as a UV light source.

[0038] Please refer again Figures 1 to 4 In the first embodiment, a heat dissipation block group 12 is also attached to the outer wall of the coolant circulation pipe 11 .

[0039] The heat dissipation block group 12 includes a plurality of evenly distributed heat dissipation blocks 121, and the heat dissipation blocks 121 are connected to the outer wall of the coolant circulation pipe 11 where the heat sink group 13 is located. That is, the heat dissipation block group 12 is arranged on the pipe wall of the horizontal pipe part 112. Without occupying the connection position of other components, the outer pipe wall of the horizontal pipe part 112 can completely cover the heat dissipation blocks 121, so that the heat transferred from the pipe wall is quickly released to the ambient air through the heat dissipation blocks 121, further improving the heat dissipation effect.

[0040] See also Figures 5 to 8 , which is a second embodiment of the cooling mechanism 100 of the gas reflux system. In this second embodiment, the heat sink group 13 is replaced by a heat pipe group 22. The heat pipe group 22 includes a plurality of cross-distributed heat pipes 221, and the heat pipes 221 are arranged perpendicular to the flow direction of the coolant. The plurality of heat pipes 221 are arranged parallel to each other and are arranged perpendicular to the flow direction of the coolant. Crossing means that adjacent heat pipes 221 are not distributed at the same height in the vertical direction in the flow direction of the coolant, so that when the coolant flows through the heat pipes 221, it contacts at least one of the heat pipes 221, thereby improving the heat dissipation effect.

[0041] Specifically, the cooling mechanism 100 of the gas reflux system of the second embodiment includes: a coolant circulation pipeline 21 , and the heat dissipation pipe group 22 is arranged in the tube cavity of the coolant circulation pipeline 21 .

[0042] The coolant circulation pipe 21 includes a vertical pipe portion 211 and a horizontal pipe portion 212, and the vertical pipe portion 211 and the horizontal pipe portion 212 are perpendicular to each other. It can be understood that in other embodiments, the shape and structure of the coolant circulation pipe 11 can also be other structures, and are not limited thereto.

[0043] The air inlet end 2111 of the coolant circulation pipe 21 is used to receive the gas outflow end of the cooling component. The horizontal pipe part 212 is also provided with a coolant output end 2121.

[0044] In this embodiment, the heat dissipation pipe group 22 is arranged near the coolant output end 2121. Similar to the first embodiment, the outer tube wall of the coolant circulation pipe 21 is also provided with a heat dissipation block group (not shown in the figure), and the heat dissipation block group structure is the same as the heat dissipation block group 12 in the embodiment. Preferably, the heat dissipation block group abuts against the outer tube wall of the horizontal pipe part 212, which is used to improve the heat dissipation effect.

[0045] Specifically, in the above-mentioned first embodiment and second embodiment, a heat exchanger (not shown in the figure) is also provided in front of one end of the air outlet of the coolant circulation pipe 11 (21), and the heat exchanger is used to absorb heat from the coolant gas with a higher temperature, reduce its temperature and output it from its output port.

[0046] In order to increase the circulation speed of the coolant during the refrigeration process, the air outlet end of the heat exchanger is also provided with an air extraction device, which includes a fan, a blower, etc.

[0047] An embodiment of the present invention provides a UV lamp, which includes the cooling mechanism 100 applied to the gas reflux system as described in any one of the above embodiment 1 or embodiment 2.

[0048] This embodiment is applied to the cooling mechanism of the gas reflux system and its UV lamp. It adds a heat dissipation block group on the outer wall of the coolant circulation pipeline and adds a heat dissipation fin group or a heat dissipation tube group in the pipe cavity, thereby utilizing the space of the coolant circulation pipeline to improve the cooling effect of the reflux coolant, thereby improving the temperature control of the UV lamp.

[0049] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention shall be subject to the claims.
