Embodiment Construction

[0030] The present invention will be further described below, and the examples listed below only represent one or several best implementation modes, and should not be construed as limiting the present invention.

[0031] Such as figure 1 As shown, the heat exchange device includes a housing 2, two heat exchange tube fixing plates 3 and several heat exchange tubes 1; the heat exchange tube fixing plates 3 and the heat exchange tubes 1 are installed in the housing 2, and the middle The axis is parallel to the heat exchange tube 1 and perpendicular to the heat exchange tube fixing plate 3, the heat exchange tube 1 is welded between two heat exchange tube fixing plates 3, and the edge of the heat exchange tube fixing plate 3 is welded to the shell 2 on the inner wall.

[0032] Such as figure 2 As shown, the heat exchange tube fixed plate 3 is plate-shaped and is provided with a plurality of through holes. The diameters of these through holes are the same. Except for the through...

Abstract

The invention provides a technology for manufacturing heat exchanging device, and relates to the technical field of machinery manufacturing. The technology comprises the following steps: (1) opening a hole; intercepting a section of tube with opening in two ends thereof as a housing of the heat exchanging device based on the dimension requirements of a blueprint; (2) fixing disk; welding two heating exchanging tube fixing disks inside the tube, wherein the heat exchanging tube fixing disks are provided with a plurality of through holes; (3) inserting tube; vertically placing the tube which is welded with the heat exchanging tube fixing disks on a welding platform, and inserting the heat exchanging tubes into the through holes of the heat exchanging tube fixing disks; (4) grinding; adjusting the lengths of the heat exchanging tubes and removing the burrs of the heat exchanging tubes; and (5) welding; using a laser welding device to weld the heat exchanging tubes on the heat exchanging tube fixing disks under the protection of an inert gas. The provided technology for manufacturing heat exchanging device is able to weld the heat exchanging tubes having a 0.4 mm to 0.5 mm tube wall thickness on the heat exchanging tube fixing disks, and is able to prevent the heat exchanging tubes from being bent in the welding process.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a manufacturing process of a heat exchange device. Background technique [0002] The welding method adopted in the manufacturing process of the heat exchange device in the past requires the thickness of the heat exchange tube of the heat exchange device to be greater than 0.8 mm. If the tube wall of the heat exchange tube is thicker, the heat transfer rate of the heat exchange tube is slow; if the tube wall of the heat exchange tube is too thin, the heat exchange tube is easily welded through during the welding process. Moreover, for a heat exchange device with the same volume, the thicker the tube wall, the smaller the heat exchange area. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the current existing heat exchange device manufacturing process can only weld heat exchange tubes with a thickness greater ...
