[0002] Ultraviolet sterilizers are widely used in the field of sewage treatment. LED ultraviolet lamps have advantages over traditional ultraviolet lamps because of their characteristics such as no illumination attenuation throughout the life cycle, low voltage power supply and low power consumption. However, due to the problem of excessive heat generation, they cannot be widely used in ultraviolet sterilizers. The Chinese utility model patent "Air-cooled ultraviolet sterilizer" with announcement number CN208933031U discloses an air-cooled ultraviolet sterilizer composed of a metal cylinder, a glass sleeve, an ultraviolet light emitter, a cooling fan and a control circuit, which solves the problem that LED ultraviolet lamps cannot be used in ultraviolet sterilizers due to heat generation. However, since the cooling fan is not effective in extracting heat from the metal cylinder, the air cooling method cannot effectively control the temperature rise, making the air-cooled ultraviolet sterilizer unable to be used continuously for a long time.

Detailed Description of the Preferred Embodiments

[0016] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to specific examples and the accompanying drawings. It should be noted that the directional terms mentioned in the examples, such as "upper", "lower", "middle", "left", "right", "front", "rear", etc., are only with reference to the directions of the accompanying drawings. Therefore, the directions used are only for illustration and not for limiting the protection scope of the present utility model.

[0017] See Figure 1 and 2 A water-cooled flow-through LED ultraviolet sterilizer is composed of a sterilizer main body 1, an LED ultraviolet disinfection device 2 and a water cooler 3.

[0018] The sterilizer main body 1 includes a sterilization tube 1-1, a sterilization water inlet 1-2 and a sterilization water outlet 1-3. The sterilization tube 1-1 is a hollow columnar tube. The sterilization water inlet 1-2 and the sterilization water outlet 1-3 are respectively opened on the side walls at both ends of the sterilization tube 1-1, and the sterilization water inlet 1-2 and the sterilization water outlet 1-3 are communicated with the inner cavity of the sterilization tube 1-1. The sterilization tube 1-1 is made of common materials such as PPR, plastic, copper or stainless steel on the current market. In the preferred embodiment of the present utility model, the sterilization tube 1-1, the sterilization water inlet 1-2 and the sterilization water outlet 1-3 are made of stainless steel.

[0019] The LED ultraviolet sterilizer 2 includes an LED fixing tube 2-1, a transparent protection tube 2-2, and multiple LED ultraviolet lamp groups 2-3. Both the LED fixing tube 2-1 and the transparent protection tube 2-2 are hollow cylindrical tubes. The multiple LED ultraviolet lamp groups 2-3 are distributed and installed on the outer side wall of the LED fixing tube 2-1, and the light-emitting directions of all the LED ultraviolet lamp groups 2-3 are towards the radially outer side of the LED fixing tube 2-1. The transparent protection tube 2-2 is sleeved on the radially outer side of the LED fixing tube 2-1 and its LED ultraviolet lamp groups 2-3. Each LED ultraviolet lamp group 2-3 consists of a light-emitting control board and several LED ultraviolet lamps installed on the light-emitting control board. All the LED ultraviolet lamp groups 2-3 are evenly distributed on the outer side wall of the LED fixing tube 2-1, and the quantity and density of the LED ultraviolet lamp groups 2-3 are adjusted according to requirements to ensure that the ultraviolet light emitted by them can be evenly radiated outward into the entire inner cavity of the sterilizing tube 1-1. As the installation tube for the LED ultraviolet lamp groups 2-3, the LED fixing tube 2-1 needs to be made of a material with good heat dissipation performance, such as metal. In the preferred embodiment of the present utility model, the LED fixing tube 2-1 is made of aluminum material. Considering the installation of the LED ultraviolet lamp groups 2-3, the LED fixing tube 2-1 adopts a polygonal pipe, such as a hexagonal pipe, etc., so that the ultraviolet light emitted by the LED ultraviolet lamp groups 2-3 has a wider and more uniform coverage area, greatly improving the sterilization efficiency. As the transmission tube for the LED ultraviolet lamp groups 2-3, the transparent protection tube 2-2 needs to be made of a material with high ultraviolet transmittance and good insulation performance, such as transparent plastic or quartz glass, etc. In the preferred embodiment of the present utility model, the transparent protection tube 2-2 is made of quartz glass material. There is a gap between the inner side wall of the transparent protection tube 2-2 and the outer side wall of the LED fixing tube 2-1 to avoid direct heat transfer to the transparent protection tube 2-2 and prevent the formation of water scale.

[0020] The water cooler 3 includes a water cooling tube 3-1, a water cooling inlet 3-2, and a water cooling outlet 3-3. The water cooling tube 3-1 is a hollow cylindrical tube, and the water cooling inlet 3-2 and the water cooling outlet 3-3 are respectively arranged at both ends of the water cooling tube 3-1, and the water cooling inlet 3-2 and the water cooling outlet 3-3 are communicated with the inner cavity of the water cooling tube 3-1. In order to improve the heat dissipation effect, the water cooling tube 3-1 needs to be made of a material with good heat dissipation performance and corrosion resistance, such as metal. In the preferred embodiment of the present utility model, the water cooling tube 3-1 is made of 304 stainless steel material.

[0021] The water cooler 3, the LED ultraviolet sterilizer 2, and the sterilizer main body 1 are nested and arranged from the inside to the outside and are fixed together by end caps 4 at both ends. The central axes of the water cooler 3, the LED ultraviolet sterilizer 2, and the sterilizer main body 1 coincide. The inner cavity of the water cooler 3 forms a cooling water channel. The outer side wall of the water cooler 3 is in contact with the inner side wall of the LED ultraviolet sterilizer 2, and the gap between the outer side wall of the LED ultraviolet sterilizer 2 and the outer side wall of the sterilizer main body 1 forms a sterilizing water channel.

[0022] The water channel formed by the sterilization water inlet 1-2, the sterilization water channel, and the sterilization water outlet 1-3 can be independent of or in series with the water channel formed by the water cooling inlet 3-2, the cooling water channel, and the water cooling outlet 3-3. When the two water channels are independent: the sterilization water inlet 1-2 forms the inlet for the water to be sterilized, and the sterilization water outlet 1-3 forms the outlet for the water to be sterilized; the cooling water inlet forms the cooling water inlet, and the cooling water outlet forms the cooling water outlet. At this time, the water to be sterilized flows in from the sterilization water inlet 1-2, passes through the sterilization water channel, and flows out from the sterilization water outlet 1-3, while the cooling water flows in from the cooling water inlet, passes through the cooling water channel, and flows out from the cooling water outlet. When the two water channels are in series, the water cooling inlet 3-2 forms the total inlet for the water to be sterilized, the water cooling outlet 3-3 is connected to the sterilization water inlet 1-2, and the sterilization water outlet 1-3 forms the total outlet for the water to be sterilized. At this time, the water to be sterilized enters from the water cooling inlet 3-2, passes through the cooling water channel, flows out from the water cooling outlet 3-3, then flows in from the sterilization water inlet 1-2, and passes through the sterilization pipe water channel and flows out from the sterilization water outlet 1-3. In the preferred embodiment of the present utility model, the two water channels are connected in series.

[0023] In order to further improve the heat dissipation effect, the sterilization water inlet 1-2 and the water cooling outlet 3-3 are located at the same end, and the sterilization water outlet 1-3 and the water cooling inlet 3-2 are located at the same end, so that the water flow direction in the cooling water channel is opposite to that in the sterilization water channel. Since the water flow rate of the cooling water can be controlled, and the water flow rate affects the heat dissipation effect of the LED ultraviolet disinfection device 2, the water flow rate of the cooling water is adjusted according to the heat generation of the LED ultraviolet disinfection device 2 to achieve the effect of rapid heat dissipation.

[0024] Considering that there is water flow in the inner cavities of both the water cooler 3 and the sterilizer 1-1, and there is a circuit in the LED ultraviolet disinfection device 2, a sealed connection is provided at the two ends where the inner side wall of the water cooling pipe 3-1 is connected to the outer side wall of the transparent protection tube 2-2, a sealed connection is provided at the two ends where the inner side wall of the transparent protection tube 2-2 is connected to the outer side wall of the LED fixing tube 2-1, and a sealed connection is provided at the two ends where the inner side wall of the LED fixing tube 2-1 is connected to the outer side wall of the sterilization tube 1-1 to avoid the influence of water vapor on the circuit.

[0025] In a preferred embodiment of the present utility model, the cooling water channel and the sterilizing water channel are connected in series. The water to be sterilized enters the cooling water channel from the water cooling inlet 3-2, flows through the cooling water channel and then flows out from the water cooling outlet 3-3. Then it enters the sterilizing water channel from the sterilizing water inlet 1-2, and flows through the sterilizing water channel and then flows out from the sterilizing water outlet 1-3. During this process, the water to be sterilized in the cooling water channel forms cooling water to absorb the heat dissipated by the LED ultraviolet lamp group 2-3, so as to achieve the purpose of heat dissipation. During the process of the water to be sterilized flowing through the sterilizing water channel, the ultraviolet light emitted by the LED ultraviolet lamp group 2-3 sterilizes it.

[0026] It should be noted that although the embodiments described above of the present utility model are illustrative, they are not limitations of the present utility model. Therefore, the present utility model is not limited to the above specific embodiments. Without departing from the principle of the present utility model, any other embodiments obtained by those skilled in the art under the inspiration of the present utility model are regarded as being within the protection scope of the present utility model.
