Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a condenser microchannel extruded tube. Background Art

[0002] Microchannel aluminum extruded tube is a thin-walled porous flat tubular material made of refined aluminum rods, through hot extrusion and surface zinc spraying for corrosion protection. It is mainly used in air-conditioning systems of various refrigerants. As a pipeline component carrying new environmentally friendly refrigerants, it adopts a new environmentally friendly system and is a key material for the new generation of parallel flow microchannel air-conditioning heat exchangers.

The cooling channel between the two sides of the tube wall has low strength and is easily deformed and dented after being compressed. It does not match the shape of the sealing covers at both ends of the microchannel extruded tube, which easily causes coolant leakage. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] The utility model embodiment provides a condenser microchannel extruded tube,

[0026] like Figure 1-5 As shown, it includes an extruded tube body 1, a plurality of support ribs 2 are arranged in the extruded tube body 1, and the front and rear side walls of the extruded tube body 1 are plugged with an arched guide plate 3 recessed toward the middle, and a first cooling channel 4 is formed between the arched guide plate 3 and the extruded tube body 1, and the support ribs 2 abut against the side of the arched guide plate 3 facing the side wall of the extruded tube body 1, and a plurality of longitudinal ribs 6 are arranged on the side of the arched guide plate 3 facing away from the front side wall of the extruded tube body 1, and a second cooling channel 5 is formed between two adjacent longitudinal ribs 6, and the arched guide plate 3 is provided with a plurality of support ribs 2. The flow plate 3 includes a plurality of integrally formed guide portions 31 and connecting portions 32. The cross-section of the guide portion 31 is shuttle-shaped. L-shaped limit strips 7 are provided on both sides of the inner wall of the extruded tube body 1. The two ends of the arched guide plate 3 are inserted between the L-shaped limit strip 7 and the inner wall of the extruded tube body 1. The front end of the guide portion 31 abuts against the inner wall of the L-shaped limit strip 7. A limit block 8 is provided at the lower end of the L-shaped limit strip 7. The front side of the connecting portion 32 abuts against the limit block 8, and the upper edge of the limit block 8 abuts against the lower side of the guide portion 31.

[0027] It is further configured that a plurality of corrugated grooves are provided on the inner wall of the extruded tube body 1, and a plurality of limiting blocks are provided on the side of the support rib 2 facing the corrugated grooves, and the limiting blocks are engaged in the limiting grooves with concave-convex fitting.

[0028] Working principle: In the utility model, an arched guide plate is arranged inside the extruded tube body and supported by supporting ribs to support the front and rear side walls of the extruded tube body, thereby increasing the heat exchange area and ensuring that the front and rear side walls of the extruded tube body will not deform after being compressed;

[0029] The coolant enters the extruded tube body 1 from one end of the extruded tube body 1, and the coolant in the hollow position of the first cooling channel 4 and the second cooling channel 8 flows in a vertical direction. The coolant passing through the arched guide plate 3 impacts the shuttle-shaped guide part 31. Part of the coolant will form a diversion through the surface of the guide part 31 and impact on both sides of the guide part 31, and the other part will adhere to the surface of the guide part 31 and flow downward. The coolant in the diversion part will impact the coolant flowing vertically to cause coolant disturbance, so that the coolant can fully exchange heat with the extruded tube body 1, thereby ensuring the heat exchange efficiency of the extruded tube body 1.

[0030] In addition, by adjusting the position of the support rib 2 in the limit slot, the support position of the support rib 2 on the arched guide plate 3 can be adjusted, and the curvature of the arched guide plate 3 can be adjusted to adjust the optimal supporting force, so that the extruded tube body 1 remains in its original state and avoids deformation.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
