Description

Technical Field

[0001] This invention relates to the field of cooling components technology, and more specifically to a ceramic plate processing apparatus for the production of cooling components. Background Technology

[0002] The working principle of the cooling element is based on Peltier's principle, which was first discovered by J.A. Peltier in 1834. Peltier's principle states that when a circuit composed of two different semiconductors A and B is energized with direct current, some kind of heat is released at one junction in addition to Joule heating, while the other junction absorbs heat. The phenomenon caused by Peltier's effect is reversible. When the direction of the current is changed, the junctions that release and absorb heat also change. The heat absorbed and released is proportional to the current intensity.

[0003] The cooling device includes two ceramic plates located on the upper and lower sides, namely an upper ceramic plate and a lower ceramic plate. Multiple conductive sheets are welded to the bottom of the upper ceramic plate, and these conductive sheets are called upper conductive sheets. Multiple conductive sheets are welded to the top of the lower ceramic plate, and these conductive sheets are called lower conductive sheets. In addition, multiple grains are welded between the upper and lower conductive sheets.

[0004] The ceramic plate has a welding surface for welding conductive sheets, and the welding surface has multiple grooves for placing conductive sheets. The multiple grooves are arranged in multiple rows and columns, and the surface of the ceramic plate opposite to the welding surface is the outside. In the prior art, the ceramic plates used are directly supplied by the ceramic plate manufacturer, and their welding surfaces are smooth. Such ceramic plates have the disadvantage of weak welding of conductive sheets, and the conductive sheets are easy to fall off during use, which affects the service life of the cooling components. Summary of the Invention

[0005] The present invention addresses the above-mentioned shortcomings by providing a processing device for ceramic plates with uneven welding surfaces that ensures strong welding of conductive sheets—a processing device for ceramic plates used in cooling components.

[0006] The technical solution of the present invention is implemented as follows: a processing device for ceramic plates used in cooling components; characterized in that: it includes a heating chamber, the heating chamber being a tunnel-type heating chamber, the heating chamber having an inlet on the left and an outlet on the right, a conveyor roller inside the heating chamber, and a conveyor belt wound around the conveyor roller, the conveyor belt having a box, the top of the box being open, the open portion being the top opening of the box, the top opening of the box being the placement position for placing the ceramic plate; the ceramic plate has a welding position for welding conductive sheets, and the positions outside the welding positions are non-welding positions, when the ceramic plate is placed in the placement position, the projection of the welding position is inside the top opening of the box.

[0007] Furthermore, when one or more ceramic plates are placed in the designated location, the ceramic plates will form a closed state on the top of the box.

[0008] Furthermore, the box has longitudinal and / or transverse steel wires at its top opening. When the ceramic plate is placed at the top opening of the box, the steel wires block the non-welding positions, but do not block the welding positions.

[0009] Furthermore, the heating chamber is equipped with a heating device that can raise the temperature of the heating chamber to 400-500°C.

[0010] Furthermore, there is an air inlet pipe connected to the box, and the outer end of the air inlet pipe has a flared opening; the high-temperature section of the heating chamber, where the temperature reaches 400-500℃, also includes a blower pipe, which has one or more blower pipe outlets in the high-temperature section, and the blower pipe outlets travel along the path of the flared opening.

[0011] Furthermore, it also includes a cooling device having a cooling pipe that is wound around the blower pipe, the cooling pipe causing the airflow temperature inside the blower pipe to reach 10-20°C.

[0012] Furthermore, the box contains a mixture of pulverized sodium chloride and aluminum oxide.

[0013] Furthermore, the mixture also contains pulverized slag, and the weight ratio of sodium chloride, aluminum oxide and slag is 2:2:1.

[0014] Furthermore, the top opening of the box and the box itself are detachable and movably connected.

[0015] The beneficial effect of the present invention is that the ceramic plate processing apparatus for such a cooling component provides a ceramic plate with a non-smooth welding surface, which can ensure that the conductive sheet is firmly welded. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] As shown in the figure, a device for processing ceramic plates used in cooling components is characterized by comprising a heating chamber 1, which is a tunnel-type heating chamber with an inlet 11 on the left and an outlet 12 on the right. A conveyor roller 13 is located within the heating chamber, and a conveyor belt 14 is wound around the conveyor roller. A box 15 is mounted on the conveyor belt, and the top of the box is open, forming the upper opening of the box. The upper opening of the box is the placement position for the ceramic plate 2. The ceramic plate has welding positions 21 for welding conductive sheets, and non-welding positions 22 outside the welding positions. When the ceramic plate is placed in the placement position, the projection of the welding positions is inside the upper opening of the box.

[0024] When processing the ceramic plate, place the ceramic plate in the designated position with the side of the ceramic plate with the welding position facing down towards the inside of the box. Place some evaporated salt inside the box. Under high temperature (this device utilizes a heating chamber), the evaporated salt in the heating chamber forms particles and disperses inside the box. Some of the evaporated salt particles will gather and adhere to the welding position of the ceramic plate, making the welding position rough, which is beneficial for welding the conductive sheet and achieves the purpose of this invention.

[0025] The purpose of the statement "when the ceramic plate is placed in the placement position, the projection of the welding position is inside the top opening of the box" is to ensure that the welding position is adhered to the evaporated salt and forms a rough surface without any blank areas.

[0026] The top of the box can contact the non-welded parts of the ceramic plate to support it, such as the surrounding area of ​​the ceramic plate.

[0027] The box can be placed on the conveyor belt at the inlet and removed from the conveyor belt at the outlet.

[0028] Furthermore, when one or more ceramic plates are placed in the designated location, the ceramic plates will form a closed state on the top of the box.

[0029] The present invention is designed such that when one or more ceramic plates are placed in the placement position, the box forms a relatively closed space, which is conducive to the accumulation and condensation of evaporated salt at the welding position, resulting in better treatment effect.

[0030] Furthermore, the top opening of the box has longitudinal and / or transverse steel wires or steel bars 16. When the ceramic plate is placed on the top opening of the box, the steel wires block the non-welding positions and do not block the welding positions.

[0031] This design ensures that the non-welded areas of the ceramic plate do not become rough after processing, which helps to guarantee product quality. This design also reduces the deformation of the ceramic plate.

[0032] Furthermore, the heating chamber is equipped with a heating device 17, which can raise the temperature of the heating chamber to 400-500°C.

[0033] This invention is designed to ensure that the salt mist formed by the evaporated salt at this temperature has the advantage of being firmly bonded to the ceramic plate.

[0034] Furthermore, there is an air inlet pipe 18 connected to the box, the outer end of which has a flared opening 181. The box has a mesh 182, and the air inlet pipe leads to the bottom of the mesh. The heating chamber temperature reaches 400-500℃ in the high-temperature section 19, which also includes a blower pipe 3. The blower pipe has one or more blower pipe outlets 31 in the high-temperature section of the heating chamber, and the blower pipe outlets follow the path of the flared opening.

[0035] This invention is designed to ensure that the evaporated salt forms salt mist at this temperature, resulting in a large amount of salt mist dust inside the box. This ensures that the welded parts can fully adhere to the salt particles and makes the welded parts rough.

[0036] Furthermore, it also includes a cooling device having a cooling pipe 4, which is wrapped around the blower pipe, and the cooling pipe makes the airflow temperature inside the blower pipe reach 10-20°C.

[0037] This invention allows for an extremely cold process in which salt particles adhere to the ceramic plate, resulting in more sharp edges on the rough surface and thus a more robust welded conductive sheet.

[0038] Furthermore, the box contains a mixture of pulverized sodium chloride and aluminum oxide.

[0039] Furthermore, the mixture also contains pulverized slag, and the weight ratio of sodium chloride, aluminum oxide and slag is 2:2:1.

[0040] This invention, with its specific design, can effectively increase the toughness of the ceramic slab.

[0041] Furthermore, the top opening of the box and the box itself are detachable and movably connected.

[0042] This invention is designed to make it easy to replace the salt inside the box.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
