[0025] In order to more clearly illustrate the embodiments of the present application, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.
[0026] In the description of the embodiments of the present application, the terms "upper", "lower", "front", "rear", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the application. In addition, the terms "first", "second", etc. are only used to distinguish in the description and have no special meaning.
[0027] According to some embodiments of the present application, Figures 1 to 5 As shown, a welding head liquid cooling structure is provided, including a liquid cooling body 1, an elastic heat conductive layer 2, a cooling layer 3 and a pressing frame 4. The pressing frame 4 presses the cooling layer 3 to the elastic heat conductive layer 2 so that the surface of the elastic heat conductive layer 2 protrudes from the pressing frame 1. One side of the elastic heat conductive layer 2 is attached to the liquid cooling body 1, and the other side is attached to the surface of the welding head 5. A cooling pipe 13 is arranged inside the liquid cooling body 1 and is used to fill with coolant.
[0028] Specifically, the pressing frame 4 is locked with the liquid cooling body 1 to press the cooling layer 3 and the elastic heat conductive layer 2 to the middle of the liquid cooling body 1. The pressing frame 4 fastens the elastic heat conductive layer 2 and the cooling layer 3 around, and the pressing frame 4 is fixedly connected to the liquid cooling body 1. The frame of the pressing frame 4 is connected to the cooling layer 3, and the middle of the pressing frame 4 is hollowed out so that the cooling layer 3 protrudes from the frame and fits with the surface of the welding head.
[0029] Furthermore, the elastic heat conductive layer 2 cooperates with the cooling layer 3 and is attached to the surface of the welding head 5 to cool the welding head 5. The elastic heat conductive layer 2 not only has a rebound effect, but also can conduct heat, so that heat is transferred between the elastic heat conductive layer 2 and the cooling layer 3.
[0030] Furthermore, the liquid-cooled body 1 has a square structure, and a cooling pipe 13 is arranged inside the liquid-cooled body 1. The cooling pipe 13 is arranged in a curved shape. The cooling pipe 13 can be set to a U-shaped structure to ensure that the liquid fully cools the liquid-cooled body 1. The shape of the cooling pipe 13 can also be set to an S-shaped structure, etc., which is not limited to the above form and can be specifically set according to actual needs.
[0031] Furthermore, the liquid cooling body 1 is provided with a liquid inlet hole 11 and a liquid outlet hole 12, which are respectively connected to the cooling pipe 13 to ensure the circulation of the liquid in the cooling pipe 13. The liquid inlet hole 11 and the liquid outlet hole 12 are connected to the external coolant, and the coolant can be cooling water or other liquids.
[0032] Furthermore, the thickness of the elastic heat-conducting layer 2 is greater than the thickness of the cooling layer 3, and the elastic heat-conducting layer 2 is protruded from the pressing frame 4. The heat of the welding head is directly transferred to the cooling layer 3, transferred to the elastic heat-conducting layer 2 through the cooling layer 3, and finally transferred to the liquid cooling body 1, and the heat is taken away by the coolant in the liquid cooling body 1, thereby realizing the cooling of the welding head.
[0033] Furthermore, the thickness of the cooling layer 3 is set to 0.01-0.4 mm, and can be set within the range of 0.01-0.4 mm, preferably set to 0.2 mm, and can be specifically set according to actual needs.
[0034] When there is a gap α between the upper and lower sides of the liquid cooling structure and the side of the welding head 5, or when there is a gap β between the front and rear sides of the liquid cooling structure and the side of the welding head 5, the gap error can be overcome by the automatic rebound effect of the elastic heat conductive layer 2 to ensure that the cooling layer 3 and the welding head 5 are completely in contact, so as to achieve the purpose of adaptive adjustment without affecting the cooling of the welding head.
[0035] In some embodiments of the present application, the cooling layer 3 is configured as copper foil or aluminum foil, which has good thermal conductivity. The copper foil or aluminum foil can ensure that when the elastic thermal conductive layer 2 is pressed against the liquid cooling body 1, the heat of the welding head is transferred to the elastic thermal conductive layer 2 and then to the cooling liquid.
[0036] If thermally conductive silicone is used alone to attach to the welding head, it is easy to tear or adhere to the surface of the welding head when the thermally conductive silicone is separated from the welding head after heating, which not only affects the thermal conductivity effect, but also affects the beauty of the product. In some embodiments of the present application, by configuring the elastic thermally conductive layer 2 as thermally conductive silicone, attaching the cooling layer 3 to the outside of the elastic thermally conductive layer 2, so that the cooling layer 3 is in direct contact with the welding head, on the one hand, the thermally conductive silicone can play a good heat conduction role, and on the other hand, the thermally conductive silicone has good elasticity, which can make the thermally conductive silicone fully contact with the surface of the welding head body, avoiding the appearance of a gap between the liquid cooling structure and the welding head, and better cooling the welding head.
[0037] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.
[0038] The above description is only a detailed description of the preferred embodiments and principles of the present application. For ordinary technicians in this field, there will be changes in the specific implementation methods based on the ideas provided by the present application, and these changes should also be regarded as the scope of protection of the present application.
