Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Referring to fig. 1 and 2, a collecting pipe capable of adjusting internal flow includes a collecting pipe 1, a plug, a flat pipe 2 and an edge plate, a top end face and two side faces of the collecting pipe 1 are bent to form an angle of 90 degrees, a bottom end face of the collecting pipe 1 is an arc-shaped face, the two side faces are in arc-shaped transition connection with the top end face and the bottom end face of the collecting pipe 1, and the top end face of the collecting pipe 1 is equidistantly provided with a socket 3;

in the structure, as the section of the collecting pipe 1 is D-shaped, when the pressure plate, the hose and the drying bottle are fixed on the collecting pipe 1, the fixing frame can be fixed on two side surfaces (planes), and compared with the traditional circular pipe, the fixing mode is firmer and more reliable, and displacement is not easy to generate; meanwhile, the length of the two side panels of the D-shaped collecting pipe 1 can be increased on the premise of not enlarging the height of the pipe (namely the inner diameter of the circular pipe), so that the space in the pipe is increased, and the D-shaped collecting pipe can adapt to larger medium flow, and the structure is very suitable for the requirements of an automobile heat exchanger with small installation space and large requirement on the flow in the collecting pipe 1;

the flat tube 2 is a micro-channel flat tube 2, two ends of the flat tube 2 are provided with limiting structures, and two ends of the flat tube 2 are inserted into the sockets 3 and are limited by the limiting structures;

the depth of the flat tube 2 inserted into the collecting pipe 1 can be adjusted by arranging the position of the limiting structure, when the flat tube 2 is inserted into the collecting pipe 1 deeply, the space in the collecting pipe 1 becomes narrow, the flow rate becomes small, otherwise, the flow rate in the collecting pipe 1 becomes large;

specifically, as shown in fig. 3, the limiting structure is a limiting insertion end 4 arranged at an end of the flat pipe 2, the width of the limiting insertion end 4 corresponds to that of the socket 3 and is smaller than that of the flat pipe 2, the limiting insertion end 4 is inserted into the socket 3, and the flat pipe 2 is limited at the outer side of the top end face of the collecting pipe 1 and is welded with the collecting pipe 1;

it should be noted that the number of the micro-channels in the limiting insertion end 4 is the same as the number of the micro-channels in the flat tubes 2, the diameter of the micro-channels in the limiting insertion end 4 is smaller than that of the micro-channels in the flat tubes 2, and the micro-channels in each limiting insertion end 4 are connected with the corresponding micro-channels in the flat tubes 2 in a bending manner; the structure can ensure the circulation of media in each micro-channel and prevent the blockage of part of micro-channels so as to reduce the heat exchange efficiency of the heat exchanger;

the limiting structure can also be a plurality of limiting frames, the limiting frames are welded on the inner sides of two ends of the flat pipe 2, one end of the flat pipe 2 is inserted into the corresponding socket 3, the limiting frames are abutted against the outer side of the top end face of the collecting pipe 1 and are welded with the collecting pipe 1, and compared with the structure that the limiting insertion end 4 is directly arranged on the end part of the flat pipe 2, the structure has the advantages of simple processing and difficult leakage;

the two limit structures also have the following advantages: the existence of limit structure still makes the workman become simply with flat pipe 2 insert the process time of pressure manifold 1, need not the setting of locating plate can make flat pipe 2 insert the degree of depth unanimously, is favorable to improving the quality of product.
