Embodiment Construction

[0012] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0013] refer to figure 1 , figure 2 , Two rollers 1 form a pair of rollers, and the roller shafts 3 are installed on the gearbox 4 respectively, and the gearbox 4 is driven by the motor 5, and the frequency regulator 6 is installed on the gearbox 4. The circular heat pipe 2 is interspersed between the two rollers 1. The inner groove C of the roller 1 clamps the heat pipe 2 tightly on both sides. There are several microscopic protrusions T on the inner groove C, densely covering the whole Inner concave wheel groove C, two rollers 1 carry out relative rolling on the heat dissipation pipe 2, the heat dissipation pipe 2 runs in the horizontal direction, and the frequency regulator 6 automatically adjusts the speed of the motor 5 according to the running speed of the heat dissipation pipe 2, so that the speed of the roller 1 Matching with the running spee...

Abstract

The invention relates to a high-efficiency cooling pipe for refrigeration equipment and a surface blurring method thereof. The surface blurring method comprises the following steps of: forming a roller pair by two opposite rollers (1), assembling sleeve roller shafts (3) on a gearbox (4) and connecting with a motor (5) to be assembled into processing equipment; and mounting a frequency variator (6) on the gearbox (4), driving the gearbox (4) by the motor (5) to drive the roller shafts (3) together with the two rollers (1) to relatively rotate and roll a cooling pipe (2) clamped in the middle of the roller pair so that micro-bumps (T) or micro-dents (W) are distributed on the surface of the cooling pipe (2), wherein the heights of the micro-bumps (T) or the depths of the micro-dents (W) are 20-300 micros, the diameters are 40-300 micros, and the distribution density is 1-23piece / mm<2>. Or the blurring treatment is carried out in such a way that a front cylindrical roller pair and a rear cylindrical roller pair can be respectively assembled by four cylindrical rollers (7) to relatively roll the rectangular cooling pipe (8) from the four sides, i.e. the top, the bottom, the left and the right. The blurred cooling pipe has great cooling area, good cooling effect, high heat exchange efficiency, low manufacture cost and high production efficiency.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a heat radiation pipe for refrigeration. Background technique [0002] With the economic development and the growing demands of social life, the market capacity of the domestic refrigeration industry is expanding year by year, the quality of refrigeration equipment is constantly improving, and it is developing towards large capacity, low energy consumption and miniaturization, making special heat dissipation for high-performance refrigeration evaporators and condensers Tubes are gradually replaced by threaded tubes with high heat transfer efficiency, and are developing from traditional smooth and smooth copper tubes to internally threaded and externally threaded copper tubes. The inner threaded copper tube is deep-processed on the structure of the smooth copper tube. There are toothed spiral grooves on the surface of the inner hole, and the outer surface is still a smooth tube. Although...
