Device and method for manufacturing a pin-fin radiator

technical field

The invention relates to a manufacturing device and a manufacturing method of a metal pin-fin radiator with a base cloth and a pin-fin structure, and belongs to the technical field of heat dissipation devices.

Background technique

Compared with sheet radiators, pin fin radiators have better heat dissipation performance than sheet radiators due to their light weight and larger specific surface area. Formed in other ways, the manufacturing difficulty is high, the efficiency is low, the yield rate is low, and the investment is high. The publication number is CN202420273, and the utility model patent named "Heat Exchange Unit" discloses a heat exchange unit. This heat exchange unit uses metal wires as raw materials to form a heat exchange unit with base cloth and pin ribs. The base cloth supports the needles. The raised ribs can achieve high-density ultra-fine pin ribs, thereby achieving high-efficiency heat dissipation, but this utility model patent does not propose a specific manufacturing process.

After openings are formed in heddle one and heddle two each time, the control device controls the weft thread device to guide different weft threads to pass through the opening, thereby forming a base fabric in which the base thread and the weft thread are vertically interwoven;

The looping device includes a looping piece, one end of the looping piece is placed on the base cloth, and the other end is fixed;

The twisted wire is introduced from the twisted wire device, and each time the base line 1 and the base line 2 form an opening, the twisted wire is located under the opening, and the weft thread is pressed on the twisted wire after passing through the opening, during the process of forming the next opening between the base line 1 and the base line 2 The twisted wire device is controlled by the control device so that the twisted wire goes around the loop starting piece. After the next opening is formed, the twisted wire is located under the next opening, and the weft thread passing through the next opening is pressed on the twisted wire.

Preferably, the weft thread device comprises a weft inserter.

Preferably, the loop starting device further includes a stringing rod, and the other end of the loop starting piece is connected by the stringing rod.

Preferably, the twisting device includes half heald one and half heddle two arranged in parallel in the vertical direction.

Another technical solution of the present invention is to provide a method for manufacturing a pin-fin radiator, which is characterized in that using the above-mentioned device includes the following steps:

In the first step, the second heald is raised, and the second heald eye on the second heald drives the second baseline to rise, and at the same time, the first heald is lowered, and the first heald eye on the first heald drives the first lower line to form the current opening. At the same time, half heddle 1 rises, half heald 2 descends, driving the riding heald and the stranded wire in the heald eye 3 to descend, so that the stranded wire is located below the current opening;

In the second step, the weft thread device drives the current weft thread to pass through the current opening, and the twisted thread is pressed under the current weft thread;

Step 3: Heald piece 2 goes down, heald eye 2 on heddle 2 drives baseline 2 down, while heddle 1 rises, heald eye 1 on heald 1 drives baseline 1 up, forming the next opening, and at the same time, The second half heald rises first, and under the action of the first riding heald spring and the second riding heald spring, the riding heald also rises, so that the stranded wire passing through it is higher than the coil piece, and then the first half heald is lowered to drive the riding heald to wind Descend through the loop-starting piece, so that the stranded wire passing through it goes around the loop-starting piece and reaches the bottom of the next opening;

Step 4: The weft thread device drives the next weft thread to pass through the next opening, and the twisted thread is pressed under the next weft thread;

The fifth step, returning to the first step, execute the first step to the fourth step in a cycle until the base fabric and the weft thread are vertically intertwined, and the surface of the base fabric forms an inverted V-shaped needle rib that is fixed and arranged neatly by the base fabric.
