Abstract

The invention relates to a pipe joint structure, comprising a collecting pipe for delivering fluid along a first direction, an inlet / outlet pipe for delivering fluid along a second direction which is perpendicular to the first direction and a hollow pipe joint hermetically jointed to the collecting pipe and the inlet / outlet pipe. The first joint part of the pipe joint is jointed to one end part of the inlet / outlet pipe and maintains the fluid communication, the second joint part of the pipe joint is jointed to the collecting pipe and maintains the fluid communication with the collecting pie via a hole on the side wall of the collecting pipe, thereby enabling the fluid communication between the inlet / outlet pipe and the collecting pipe is maintained. The second joint part forms a pipe-like wall or partially pipe-like wall configuration jointed to the collecting pipe. The pipe joint structure has advantages of small pressure drop in the inlet / outlet pipe, high burst strength in the joint part and low cost.

Description

technical field [0001] The present invention relates to a pipe joint structure, in particular but not exclusively to a pipe joint structure for a heat exchanger. Background technique [0002] In the application of various pipeline systems, in order to realize the change of pipeline conveying direction, the diversion of fluid, the connection between various pipelines, etc., it is inevitable to use the pipe joint structure, especially for the connection between two vertical pipelines. Connection. For example, in the existing aluminum heat exchanger, the method of directly inserting the inlet and outlet pipes as the branch pipes into the header pipe as the main pipe is usually adopted to realize the fluid communication between the two pipes. [0003] figure 1 A prior art fitting structure 10 is shown. The pipe joint structure 10 includes a header 11 for conveying refrigerant such as water in the vertical direction, a hole 12 on the side wall of the header, and an inlet and o...
