Detailed Description
Embodiments of the present invention will be described in detail below with reference to fig. 1 to 2. It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application.
referring to fig. 1, the utility model discloses annular heat-conducting plate welding set of embodiment includes base 1, stopper 2, tubular metal resonator fore-set 3, metal sheet fore-set 4, first heat dissipation part 5 and second heat dissipation part 6.
Referring to fig. 2, the first metal plate 7 and the second metal plate 8 in the embodiment of the present invention are copper plates, and the annular heat conducting metal pipe 9 is a copper pipe, and of course, may be an aluminum plate and an aluminum pipe according to actual needs.
the base 1 is the body of the entire device for carrying other components. Illustratively, the base 1 is a steel plate.
A first heat sink member 5 and a second heat sink member 6 for dissipating heat during welding are mounted on the surface of the base 1. The first heat sink member 5 and the second heat sink member 6 are both made of a heat sink material resistant to high temperature. The material of the first heat sink member 5 and the second heat sink member 6 is asbestos, for example. Specifically, the first heat sink member 5 and the second heat sink member 6 are respectively located on both sides of the surface of the base 1 so as to be aligned with the annular heat conductive metal pipe 9.
The first heat sink piece 5 carries a first metal plate 7 and the second heat sink piece 6 carries a second metal plate 8.
The annular heat-conducting metal tube 9 is in the shape of an open ring having two free sections which need to be welded to the first metal plate 7 and the second metal plate 8, respectively. On the surface of the first metal plate 7 a section 91 of the annular heat-conducting metal tube 9 is placed, and on the surface of the second metal plate 8 another section 92 of said annular heat-conducting metal tube 9 is placed.
The metal tube top column 3 and the metal plate top column 4 are respectively used for fixing the annular heat-conducting metal tube and the metal plate in the welding process. The metal pipe top pillar 3 is detachably fixed on the base 1, and a part of the metal pipe top pillar 3 can extend out to be located above a section 91 of the annular heat-conducting metal pipe 9 and is separated by a set first distance. The metal plate top pillar 4 is detachably fixed on the base 1, and a part of the metal plate top pillar 4 can extend above the first metal plate 7 and is separated by a set second distance. Illustratively, the metal tube top pillar 3 and the metal plate top pillar 4 are the same structure, and each includes a support member 31 and a projecting member 32; the support member 31 is detachably mounted on the base 1, for example, inserted in a hole of the base 1; the extension part 32 can be extended from the support part 31 by sliding, specifically, the support part 31 is provided with a through hole, the extension part 32 is a cylinder movably disposed in the through hole, and the extension part 32 can move in the through hole when being pushed, thereby extending.
Thus, the extension member 32 is a part of the metal pipe top 3 or the metal plate top 4, the surface of the extension member 32 of the metal pipe top 3 is spaced apart from the surface of the one section 91 of the annular heat conductive metal pipe 9 by a first distance, and the surface of the extension member 32 of the metal pipe top 3 is spaced apart from the surface of the first metal plate 7 by a second distance. Wherein, the first distance and the second distance are reserved for the metal tube and the metal plate to expand with heat and contract with cold in the welding process.
The limiting block 2 is detachably fixed on the base 1, and the notch 21 of the limiting block 2 can be abutted against the end part of one section 91 of the annular heat-conducting metal pipe 9, so that the deformation of the annular heat-conducting metal pipe is prevented. The end of the section 91 of the annular heat conducting metal tube 9 is bent upwards, so that the notch 21 is pressed against the part of the section 91 bent upwards.
Before welding, the positions of the annular heat-conducting metal pipes 9 on the first metal plate 7 and the second metal plate 8 are adjusted so that the positions set on the annular heat-conducting metal pipes 9 are aligned with the corresponding positions on the first metal plate 7 and the second metal plate 8. During welding, the first metal plate 7 and the section 91 of the annular heat-conducting metal tube 9 are heated according to a welding process, a welding flux is melted in, and after the welding liquid is solidified, a part of the metal tube top column 3 and a part of the metal plate top column 4 are retracted, so that the annular heat-conducting metal tube 9 is loosened, and unilateral welding is completed, namely welding of the section 91 of the annular heat-conducting metal tube 9. Then another section 92 of the annular heat conducting metal tube 9 is welded, so that a part of the metal tube top column 3 and a part of the metal plate top column 4 extend out, the second metal plate 8 and another section 91 of the annular heat conducting metal tube 9 are welded according to a welding process, and the welding of the other side is completed, so that the welding of the whole annular heat conducting plate is completed.
According to the above, one section 91 of the annular heat-conducting metal tube 9 is placed on the surface of the first metal plate 7, a portion of the metal tube top pillar 3 can extend above the one section 91 of the annular heat-conducting metal tube 9 and is spaced apart from the one section 91 of the annular heat-conducting metal tube 9 by a set first distance, the stopper 2 can abut against the end of the one section 91 of the annular heat-conducting metal tube 9, and the other section 92 of the annular heat-conducting metal tube 9 is freely placed on the second metal plate 8. So, at the in-process of welding one section 91 of annular heat conduction tubular metal resonator 9, because expend with heat and contract with cold, annular heat conduction tubular metal resonator 9 can expand, wherein, one section 91 grow to certain extent after with the partly contact that tubular metal resonator fore-set 3 stretched out to make the deformation stopped. The other section 92 of the annular heat conducting metal tube 9 is also deformed, but because it is free, it can be deformed all the time, and it can avoid that the deformation of the other section 91 is prevented. The same is true for the first metal plate 7, which is deformed to some extent and then comes into contact with a portion of the metal plate top pillar 4 projecting therefrom, so that the deformation is prevented; while the second metal sheet 8 is free and thus always deformed. When welding the other segment 92 of the annular heat-conducting metal pipe 9, the segment 91 of the annular heat-conducting metal pipe 9 and the first metal plate 7 are free and can be deformed all the time. A part of heat generated in the welding process is dissipated by the first heat sink member 5 and the second heat sink member 6, so that deformation caused by the heat can be reduced. Due to the existence of the first distance and the second distance and the unilateral fixation of the annular heat-conducting metal tube 9, the deformation of the annular heat-conducting metal tube 9, the first metal plate 7 and the second metal plate 8 can be reduced, and the yield is improved.
The present invention will be further explained below.
The first and second distances are set according to the deformation of the product, and if the material of the heat-conducting plate is deformed more when heated, the larger distance is set, and in general, the first distance is 0.05mm to 0.2mm, and the second distance is also 0.05mm to 0.2mm, which can accommodate the deformation of most materials. For the heat conducting plate made of copper, the first distance and the second distance are both 0.1mm, and high yield can be obtained.
because the annular heat-conducting metal pipe 9 is usually longer, a plurality of metal pipe top columns 3 are arranged, and the annular heat-conducting metal pipe 9 can be well fixed. The metal tube top pillar 3 and the metal plate top pillar 4 are respectively located on two sides of the heat dissipation part, so that the annular heat conduction metal tube 9 and the metal plate can be well fixed, the yield is improved, specifically, the metal tube top pillar 3 is located on one side of the first heat dissipation part 5, and the metal plate top pillar 4 is located on the other side of the first heat dissipation part 5.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific/preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. For those skilled in the art to which the invention pertains, a plurality of alternatives or modifications can be made to the described embodiments without departing from the concept of the invention, and these alternatives or modifications should be considered as belonging to the protection scope of the invention.
