[0038] Reference Figure 1-10 The figure shows a preferred embodiment of the present invention.

[0039] The compressed tube heat sink comprises a base 3 and a plurality of compressed copper tubes 1. The bottom surface of the base 3 is concavely provided with an opening groove and side strips respectively located on both sides of the opening groove. The compressed copper tube 1 comprises a round tube section 12 and a square tube section 11. The square tube section 11 comprises a first square tube section 11, a second square tube section 11 and a middle square tube section 11. The middle square tube section 11 is arranged in contact with the opening groove. Both sides of the middle square tube section 11 are compressed to form side surfaces 111. The side surfaces 111 of adjacent middle square tube sections 11 are arranged in overlapping contact. The middle square tube section 11 has a bottom surface 112. The bottom surface 112 of the middle square tube section 11 is arranged coplanar with the bottom surface of the side strips.

[0040] The above-mentioned pressed tube radiator, since the two sides of the square tube section 11 are compressed to form the side surfaces 111, reduces the occupied area of ​​a single heat dissipation copper tube, increases the number of heat pipes per unit area, reduces the load borne by a single heat dissipation heat pipe, and improves the heat dissipation effect. At the same time, under the action of the side surfaces 111, the contact area between adjacent heat dissipation heat pipes is increased, which facilitates heat conduction and improves the heat dissipation effect; and, since the bottom surfaces 112 are arranged in the same plane, the contact area with the heat source is increased, the heat exchange effect is improved, and the heat dissipation effect is further improved.

[0041] The compressed tube radiator can be used to dissipate heat from the equipment, thereby ensuring the performance stability of the equipment and ensuring the normal use of the equipment.

[0042] The device may be a computer host. A large amount of heat will be generated when the computer host is working. Overheating may cause the computer to freeze, parts to burn, etc.

The heat dissipation strips 33 are arranged in a long strip shape, and each heat dissipation strip 33 is arranged in sequence and spaced apart. The heat dissipation strips 33 extend along the axial direction of the square tube section 11, and heat dissipation channels are formed between adjacent heat dissipation strips 33. Under the action of each heat dissipation strip 33, it is convenient for the ambient airflow to carry the heat of the base 3 and the pressed copper tube 1, thereby improving the heat dissipation effect.

[0052] The two side strips are arranged in a spaced relationship with each other, and the side strips have inner side surfaces facing the central square tube section 11. The assembly groove 32 is arranged between the two inner side surfaces, and along the direction toward the arc groove 31, the two inner side surfaces are arranged in a flared shape, and the two inner side surfaces are used to squeeze each central square tube section 11 to be arranged in a pressed fit; in this way, under the action of the two inner side surfaces, the close fit of adjacent central square tube sections 11 is enhanced, which facilitates thermal interaction between the central square tube sections 11 and improves the heat dissipation effect.

[0064] The processing method of the above-mentioned pressed tube radiator is convenient for pressing and forming a square tube section 11 with two side surfaces 111 under the action of the tube pressing mold 4, and then, under the action of the assembly equipment, it is convenient for the assembly between each heat dissipation fin 21 and the pressed copper tube 1, and then, the fixing fixture 51 is used to fix and transfer the heat dissipation group, and the heat dissipation group is first transferred to the rolling device 52 to realize the rolling of the square tube section 11 to the base 3, and realize the assembly between the heat dissipation combination base 3, and then transferred to the flying surface device, and the flying surface operation is performed to form the bottom surface 112; in this way, the processing and production of the pressed tube radiator is convenient, and it helps to improve production efficiency and reduce production costs.

[0065] The tube pressing mold 4 includes a pressing plate 41 and a pressing seat 42. The pressing seat 42 has a pressing platform with a convex arrangement. The pressing platform has a flattening groove. The pressing seat 42 has a lower empty pressing groove. The lower empty pressing groove is connected to the flattening groove. The pressed copper tube 1 is placed on the pressing seat 42 so that the square tube section 11 is in the flattening groove and the round tube section 12 is in the lower empty pressing groove.

At this time, the round tube section 12 is in the lower empty pressing groove, and the square tube section 11 is in the flattening groove. The pressing seat 42 is then engaged with the pressing plate 41, and the pressing plate 41 is pressed down. Under the action of the boss, the square tube section 11 in the flattening groove is subjected to compression pressure, so that the two sides of the square tube section 11 form side surfaces 111 respectively, while the round tube section 12 in the lower empty pressing groove is not subjected to compression pressure, and the round tube section 12 does not deform.

[0067] The tube pressing mold 4 includes two positioning columns 43 and two positioning blocks 44.
