Problems solved by technology

However, the micro-groove tube array obtained by extrusion molding has relatively smooth groove surface, no rough surface structure, and small capillary suction, so the working medium can only rely on gravity to reflow, which limits the extruded aluminum profile of the micro-groove group. Application on heat pipe

Abstract

The invention discloses a micro-groove group extrusion molding device with an ultrasonic rough surface, which includes a machine head body, a main body, a fluid distribution bracket, a core mold with a flow channel inside, and an outer die. The machine head body and the main body pass through the Bolts are connected, and the sub-fluid support is fixed between the head body and the main body connection, the left end of the head body is provided with a filter screen, and the center of the mandrel is provided with an ultrasonic wave that can generate ultrasonic waves to vibrate the mandrel. For the transducer, the right end of the main body is fixedly provided with an external die for defining the cross-sectional shape of the finished product through a gland. The invention is simple in structure, easy to implement, can carry out extrusion molding processing on aluminum materials, has high production efficiency and low cost, and uses the method of ultrasonic rough surface in the production process to make the groove on the inner wall of the aluminum profile have a rough surface, thereby broadening its application occasion.

Description

Technical field [0001] The present invention involves the field of heat exchange materials, especially the microorgam group extrusion molding device that involves a rough surface of the ultrasonic rough surface. Background technique [0002] At present, the main methods of strengthening heat transfer are mainly to increase the heat transfer coefficient, expand the heat transfer area, and increase the heat transfer temperature difference.Increasing the number of heat transfer pipes in a certain heat exchanger can effectively increase the heat transfer area. In addition, rough surface roughness can effectively improve the surface heat transfer coefficient on the surface of the material, thereby improving the surface heat dissipation or heat absorption capacity, and strengthening the heat transfer process. [0003] The aluminum profiles of the microorgana gap are made of several microorph grooves. There are a lot of capillary micro -grooves, which are applied to a new type of heat p...
