Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchanger detection, in particular to a plate radiator leak detection and screening tool. Background Art

[0002] The plate heat exchanger is a high-efficiency heat exchanger made of a series of metal sheets with specified corrugated shapes. It passes two different fluids into the thin rectangular channels formed between adjacent plates, and uses the plates to expand the contact area between the two fluids, so as to achieve rapid heat exchange between different fluids. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, long service life, etc., and is widely used in the heat dissipation of electrolytic aluminum power supply systems.

[0003] At present, aluminum electrolytic plants often use liquid-liquid plate heat exchangers, which use rectangular channels to transport cooling water to cool the pure water carrying heat from the unit. Since most cooling water uses groundwater, with years of operation, impurities in the groundwater will corrode the plate heat sink, forming pitting on the plate heat sink, causing sand holes on the plate heat sink. During use, cooling water will contaminate pure water through the sand holes, causing water to flow through the rectifier unit. Under the action of high voltage and high current, electrical components of the equipment contaminated by impurities in the water will break down and discharge, seriously endangering the operation of the equipment.

[0004] Since trachoma is often small and difficult to detect with the naked eye, it is difficult and time-consuming for maintenance personnel to inspect and screen the plate heat sink. There is inevitable human error in screening with the naked eye, and the error is large, which can easily lead to trachoma not being discovered in time, causing the problematic plate heat sink to be installed on the heat exchanger. Therefore, it is urgent to design a tool to assist in the detection of trachoma in plate heat sinks to improve the detection speed and accuracy. Utility Model Content

[0005] In order to overcome the problems existing in the related technology, the utility model provides a plate heat sink leak detection screening tool to assist maintenance personnel to quickly determine whether there are trachomas in the plate heat sink and determine the location of the trachomas, thereby improving the detection speed and accuracy.

[0006] The technical solution adopted by the utility model is: a plate-type heat sink leak detection and screening tool, comprising a table body; a detection component fixedly connected to the table top of the table body; a detection cavity is formed inside the detection component, and a support plate for placing the plate-type heat sink is provided at the opening of the detection cavity, and a lighting device is installed inside the detection cavity, and the light emitted by the lighting device is irradiated onto the plate-type heat sink through the support plate.

[0007] Furthermore, the shape and size of the support plate are the same as those of the plate-type heat sink.

[0008] Furthermore, the support plate is made of transparent material.

[0009] Furthermore, the detection chamber is rectangular parallelepiped-shaped, and a light condensing layer is provided on its side walls and bottom surface.

[0010] Furthermore, the lighting device includes a mounting base and a lamp tube. The mounting base is arranged on the two end wall surfaces of the detection chamber, and both ends of the lamp tube are clamped into the mounting base.

[0011] Furthermore, there are two lighting devices, which are evenly arranged on the two end wall surfaces of the detection chamber, dividing the detection chamber into three equal parts along the width direction.

[0012] Furthermore, orifice gaskets are provided at the four corner positions of the support plate, and / or rubber gaskets are provided at the edges of the support plate.

[0013] Furthermore, the table body includes four support feet, and universal wheels are installed at the bottoms of the support feet.

[0014] Furthermore, the plate surface of the support plate is a flat straight surface, which is parallel to the horizontal plane.

[0015] The leak detection and screening tool for plate heat sinks of the present utility model has the following technical effects: By using the principle of small hole imaging in optics, a transparent support plate with the same size and shape as the plate heat sink is made. The support plate is placed on the opening of the detection assembly, and a detection chamber is formed inside the detection assembly, and a lighting device is installed in the detection chamber. The plate heat sink is placed on the support plate, and the light emitted by the lighting device passes through the support plate and irradiates onto the plate heat sink. In the case of a relatively dark surrounding environment, by observing whether there are light spots on the plate heat sink, it can be quickly determined whether there are sand holes in the heat sink and the positions of the sand holes can be determined. This screening tool can assist maintenance personnel in quickly screening out problematic heat sinks, preventing them from being installed on radiators and causing serious consequences that endanger the operation of the equipment. At the same time, the overall structure of this screening tool is simple, easy to manufacture, low in cost, simple and convenient to use, and suitable for large-scale promotion.

Detailed implementation manners

[0022] The following will explain in detail the specific implementation manners disclosed in the present utility model with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustration and explanation of the present disclosure, and are not used to limit the present disclosure.

[0023] As Figure 1 、 Figure 2 shown, it is an exemplary embodiment disclosed in the present utility model. The plate - type heat sink leak - detection and screening tool 10 of the present utility model includes a table body 20 and a detection component 30 fixedly connected to the tabletop of the table body 20. A detection cavity 31 is formed inside the detection component 30. An opening of the detection cavity 31 is provided with a support plate 40 for placing the plate - type heat sink. A lighting device 50 is installed inside the detection cavity 31, and the light emitted by the lighting device 50 passes through the support plate 40 and irradiates on the plate - type heat sink.

[0024] The plate - type heat sink leak - detection and screening tool 10 of the present utility model includes a table body 20 and a detection component 30. The detection component 30 and the tabletop of the table body 20 can be fixedly connected by fasteners such as bolts and nuts, or can be fixedly connected by welding. If the welding method is adopted, the detection component 30 and the table body 20 are of an integrally formed structure. The detection component 30 is a hollow structure with a detection cavity 31 formed inside, and a lighting device 50 is installed inside the detection cavity 31. In order to better fix the plate - type heat sink and prevent it from falling into the detection cavity 31, a support plate 40 is also provided at the opening of the detection cavity 31, and the light emitted by the lighting device 50 passes through the support plate 40 and irradiates on the heat sink. In a dark environment, it can be observed whether there are light spots on the plate surface 41 of the plate - type heat sink to determine whether there are sand holes in the plate - type heat sink and quickly determine the position of the sand holes. In this way, the screening tool can assist maintenance personnel in leak - detection and screening of plate - type heat sinks, improving the speed and accuracy of detection. The overall structure of the screening tool is simple, easy to manufacture, and convenient to use, suitable for large - scale promotion.

[0025] Exemplarily, as Figure 2 、 Figure 3As shown, in the exemplary embodiment disclosed by the present utility model, the shape and size of the support plate 40 are the same as those of the plate-shaped heat sink. The support plate 40 is made of a transparent material. The plate surface 41 of the support plate 40 is a flat surface and is parallel to the horizontal plane.

[0026] The support plate 40 is made of a transparent material, such as transparent glass, plastic, etc., so that the light emitted by the lighting device 50 can pass through the support plate 40 and irradiate onto the heat sink. The shape and size of the support plate 40 should be the same as those of the plate-shaped heat sink. When placing the plate-shaped heat sink on the support plate 40, the size and shape of the support plate 40 should just fit the heat sink. If the plate surface 41 of the support plate 40 is larger than the heat sink, the light emitted by the lighting device 50 will shoot out from the edge of the heat sink, which will interfere with the maintenance personnel's judgment on whether there are sand holes in the heat sink. If the plate surface 41 of the support plate 40 is smaller than the heat sink, part of the area of the heat sink will not be irradiated by the detection light, which will affect the accuracy of leak detection. The plate surface 41 of the support plate 40 is a flat surface. After installing the support plate 40 on the opening of the detection component 30, the plate surface 41 of the support plate 40 is parallel to the horizontal plane. In this way, when placing the plate-shaped heat sink on the support plate 40, no additional fixation is required and it will not slide off the support plate 40.

[0027] Specifically, hole channel gaskets 60 are provided at the four corner positions of the support plate 40, and / or rubber gaskets 70 are provided at the edge of the support plate 40.

[0028] The plate body of the plate-shaped heat sink has four hole channels. Correspondingly, hole channel gaskets 60 are provided at the four corner positions on the side of the support plate 40 that contacts the heat sink. When placing the heat sink on the support plate 40, the four hole channel gaskets 60 on the support plate 40 just pass through the four hole channels on the heat sink and seal the four hole channels, preventing the light irradiated on the support plate 40 from shooting out from the heat sink hole channels and affecting the maintenance personnel's judgment on whether there are sand holes in the plate-shaped heat sink. Preferably, rubber gaskets 70 are also provided at the edge of the side of the support plate 40 where the hole channel gaskets 60 are located. When placing the heat sink on the support plate 40, the rubber gaskets 70 can seal the gap between the support plate 40 and the edge of the heat sink, preventing the detection light from overflowing and affecting the judgment of the maintenance personnel, thereby improving the accuracy of leak detection. At the same time, the rubber gaskets 70 can also lift the heat sink, making it convenient to remove the heat sink from the support plate 40 after the leak detection is completed.

[0029] Exemplarily, such as Figure 2 、 Figure 3As shown, in the exemplary embodiment disclosed in the present utility model, the detection cavity 31 is in the shape of a rectangular parallelepiped, and a light-collecting layer 32 is provided on its side wall and bottom surface. The lighting device 50 includes a mounting seat 51 and a lamp tube 52, the mounting seat 51 is provided on the two end walls of the detection cavity 31, and the two ends of the lamp tube 52 are inserted into the mounting seat 51. Preferably, there are two lighting devices 51, which are evenly provided on the two end walls of the detection cavity 31, dividing the detection cavity 31 into three equal parts along the width direction.

[0030] The detection cavity 31 of the plate-type heat sink leak detection screening tool 10 of the present invention is in the shape of a rectangular parallelepiped. In order to better irradiate the detection light emitted by the lighting device 50 onto the heat sink, a focusing layer 32 is provided on the side wall and the bottom surface of the detection cavity 31. The focusing layer 32 is made of a reflective material. After the detection light is irradiated onto the side wall and the bottom surface of the detection cavity 31, it will be reflected onto the opening and gathered together to irradiate onto the heat sink. The lighting device 50 used in the plate-type heat sink leak detection screening tool 10 of the present invention is a fluorescent lamp, which includes a mounting seat 51 and a lamp tube 52. The relevant control circuit in the fluorescent lamp is installed in the mounting seat 51, and the mounting seat 51 is connected to a switch and a plug through a wire, and the power supply is connected through the plug. The mounting seats 51 are provided on the two end walls of the rectangular parallelepiped detection cavity 31, and the length of the lamp tube 52 is the same as the length of the detection cavity 31. The two ends of the lamp tube 52 are inserted into the mounting seats 51 on the two end walls of the detection cavity 31. Preferably, two fluorescent lamps can be arranged in the detection cavity 31, and the detection light emitted will be brighter. In a dark environment, if there are trachoma on the heat sink, the detection light passing through the trachoma will be brighter, the contrast will be more distinct, and it will be easier for maintenance personnel to detect. In order to make the brightness of the light irradiated to the heat sink more uniform, the two fluorescent lamps can be evenly arranged in the detection cavity 31, so that the vertical plane where the two fluorescent lamp tubes 52 are located divides the internal space of the detection cavity 31 into three equal parts along the width direction of the detection cavity 31.

[0031] For example, the table body 20 of the plate-type heat sink leak detection screening tool 10 of the utility model includes four supporting legs, and universal wheels 80 are installed at the bottom of the supporting legs. The table body 20 is designed as a four-legged supporting structure, which can make the table body 20 more stable and not easy to tip over. The universal wheels 80 are installed at the bottom of the supporting legs to facilitate the plate-type heat sink leak detection screening tool 10 to move in any direction, making the screening tool more flexible to use.
