Description

Technical Field

[0001] This utility model belongs to the field of welding technology, and more specifically, relates to a liquid-cooled plate stirring welding assembly. Background Technology

[0002] Stir welding is used in the production and processing of liquid cooling plates. First, flow channels are processed on one plate, and then another plate is fixed on by stir welding to cover the flow channels. The key point is how to open the inlet and outlet ports so that the inlet and outlet ports can be connected to the flow channels.

[0003] There are two ways to open inlet and outlet ports:

[0004] The first method involves first machining the inlet and outlet ports on the plate with the flow channel, and then stirring and welding another plate to fix it. In this method, the material will flow towards the inlet and outlet ports under the action of welding pressure during the welding process, causing the inlet and outlet ports to deform and become blocked. In addition, the material flow during welding will cause the welding material to be not compacted, forming a welding gap.

[0005] The second method is to process the inlet and outlet ports after stirring and welding; however, some special structures cannot be processed after welding.

[0006] Therefore, it is necessary to propose a structure that allows for stirring and welding after the inlet and outlet ports have been machined. Utility Model Content

[0007] The main purpose of this invention is to provide a liquid-cooled plate stirring and welding assembly, which aims to avoid clogging of the liquid passage after stirring and welding.

[0008] According to a first aspect of the present invention, a liquid-cooled plate stirring welding assembly is provided, comprising a first plate and a second plate. The first plate has a first wall surface, and at least one end of the first wall surface along a first direction is provided with a protrusion. The protrusion protrudes along a second direction, the first direction being perpendicular to the second direction. The first wall surface and the protrusion cooperate to form a receiving groove, and the bottom of the receiving groove is provided with a flow channel.

[0009] The first plate is provided with a liquid passage, which passes through the protrusion to connect the flow channel to the outside;

[0010] The second plate is located in the receiving groove, and the side of the protrusion near the second plate is welded to the second plate.

[0011] In the above-mentioned liquid-cooled plate stirring welding assembly, the liquid passage is filled with a water-soluble solid filler.

[0012] In the above-mentioned liquid-cooled plate stirring welding assembly, the second plate is higher than or flush with the protrusion in the second direction.

[0013] In the above-mentioned liquid-cooled plate stirring welding assembly, the depth of the receiving groove is 2.5 to 4.5 mm.

[0014] In the above-mentioned liquid-cooled plate stirring welding assembly, the protrusion is provided with a connecting block, the thickness of the connecting block in the second direction is greater than the thickness of the protrusion in the second direction, and the liquid passage passes through the connecting block.

[0015] In the above-mentioned liquid-cooled plate stirring welding assembly, the liquid passage includes a first channel and a connecting hole. The first channel communicates with the flow channel, and the connecting hole is located in the connecting block, and the connecting hole communicates with the first channel and the outside.

[0016] In the above-mentioned liquid-cooled plate stirring welding assembly, there are multiple connecting blocks arranged at intervals along a third direction, with the first direction, the second direction, and the third direction being perpendicular to each other.

[0017] In the above-mentioned liquid-cooled plate stirring welding assembly, the water-soluble solid filler is copper sulfate or calcium chloride.

[0018] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:

[0019] In this utility model, a protrusion is provided to construct a receiving groove. The second plate is located in the receiving groove, so that the liquid passage is lower than the second plate. The side of the protrusion near the second plate is a weld seam with the second plate. Stir welding is performed at the weld seam, so that the second plate and the protrusion are welded together, reducing the impact of welding on the liquid passage.

[0020] Meanwhile, water-soluble solid fillers can be filled into the liquid passage to prevent material from flowing into the liquid passage and ensure that the liquid passage is not blocked during the welding process. After welding is completed, the filler can be removed by water so that the liquid passage can be left intact. Attached Figure Description

[0027] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0029] Reference Figures 1 to 3 As shown, a liquid-cooled plate stir welding assembly includes a first plate 1 and a second plate 2. The first plate 1 has a first wall surface 11. At least one end of the first wall surface 11 along a first direction is provided with a protrusion 3. The protrusion 3 protrudes along a second direction. The first direction is perpendicular to the second direction. The first wall surface 11 and the protrusion 3 cooperate to form a receiving groove 12. The bottom of the receiving groove 12 is provided with a flow channel 13.

[0030] The first plate 1 is provided with a liquid passage 14, which passes through the protrusion 3 to connect the flow channel 13 with the outside.

[0031] The second plate 2 is located in the receiving groove 12, and the side of the protrusion 3 near the second plate 2 is welded to the second plate 2.

[0032] A protrusion 3 is provided on the first plate 1 to form a receiving groove 12. The second plate 2 is located in the receiving groove 12, so that the liquid passage 14 is lower than the second plate 2. The side of the protrusion 3 close to the second plate 2 is a weld seam with the second plate 2. Stir welding is performed at the weld seam, so that the second plate 2 and the protrusion 3 are welded together, reducing the impact of welding on the liquid passage 14.

[0033] Meanwhile, the liquid passage 14 is filled with water-soluble solid filler 4 to prevent material from flowing into the liquid passage 14 and to ensure that the liquid passage 14 is not blocked during the welding process. After welding is completed, the filler is removed by water so that the liquid passage 14 can be left intact.

[0034] The water-soluble solid filler 4 can be copper sulfate or calcium chloride, which are soluble in water and have a high melting point.

[0035] Of course, the first plate 1 and the second plate 2 are also welded in other positions to seal the flow channel 13, except that the liquid passage 14 is welded at the weld seam.

[0036] In this embodiment, two or more flow channels 13 can be provided on the first plate 1. The flow channels 13 are curved. One flow channel 13 corresponds to two liquid passages 14. One liquid passage 14 is for input and one liquid passage 14 is for output, thereby realizing the flow of coolant.

[0037] In this embodiment, the second plate 2 is higher than or flush with the protrusion 3 in the second direction, ensuring that the second plate 2 has sufficient area for welding.

[0038] Specifically, taking the second direction as vertically upward as an example, the top surface of the second plate 2 is higher than or level with the top surface of the protrusion 3.

[0039] Preferably, the top surface of the second plate 2 is flush with the top surface of the protrusion 3, making the liquid cooling plate more aesthetically pleasing.

[0040] In this embodiment, the depth of the receiving groove 12 is designed according to the thickness of the plate, generally 2.5 to 4.5 mm, to ensure that the second plate 2 has enough area for welding at the weld seam, so that the second plate 2 and the protrusion 3 are firmly welded.

[0041] In this embodiment, a connecting block 5 is provided on the protrusion 3, and the thickness of the connection in the second direction is greater than the thickness of the protrusion 3 in the second direction. The liquid passage 14 passes through the connecting block 5.

[0042] The liquid passage 14 includes a first channel 141 and a connecting hole 142. The first channel 141 is connected to the flow channel 13, and the connecting hole 142 is located in the connecting block 5. The connecting hole 142 connects the first channel 141 to the outside.

[0043] The connection hole 142 is relatively large, which makes it easy to arrange the connector. The first channel 141 is to be hidden in the first plate 1. Due to the thickness of the first plate 1, conventional connectors can be connected without increasing the thickness of the first plate 1.

[0044] In this embodiment, there are multiple connecting blocks 5 arranged at intervals along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other, and each connecting block 5 is connected to a liquid passage 14.

[0045] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
