The utility model discloses in, the shape of recess is the linear type, the recess for the tube sheet body is sunken downwards, the upper end of recess all around with this body coupling of tube sheet.

The utility model discloses in, the length of the recess at tube sheet body center is the longest, and the length of the recess of both sides is steadilyd decrease in proper order.

The utility model discloses in, the quantity of the tube hole in the recess at center is the most, and the quantity of the tube hole in the recess of both sides steadilys decrease in proper order.

The utility model discloses in, the shape of fin is rectangle, be parallel to each other and be equipped with equal clearance between the fin.

The utility model discloses in, the shape of stationary blade is L shape, the stationary blade is equipped with a plurality of, arranges in proper order the outside of fin.

The utility model discloses in, constitute a rectangular space between stationary blade and the recess, the fin is fixed between stationary blade and the recess.

To sum up, the beneficial effect of this application: the tube is welded in the tube hole and then contacts the side wall of the groove, heat is transferred to the two sides of the groove and dissipated by the radiating fins, and meanwhile the radiating holes between the tube holes radiate the heat, so that the radiating efficiency is greatly improved, and the situation that the heat is completely concentrated on the surface of the tube plate is avoided.

Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1, 2 and 3, a cooling tube plate comprises a tube plate body 1, wherein the tube plate body 1 is circular, the tube plate body 1 is provided with a plurality of grooves 2, the grooves 2 are parallel to each other and have equal spacing, a plurality of pipe holes 3 are uniformly arranged at the bottom of the groove 2, the pipe holes 3 are arranged in a straight line at the bottom of the groove 2, the diameter of the pipe holes 3 is equal to the width of the groove 2, heat dissipation holes 4 are arranged between the pipe holes 3, the heat dissipation holes 4 are arranged at the bottom of the groove 2, the shape of the heat dissipation holes 4 is rectangular, a plurality of radiating fins 5 are arranged on two sides of the groove 2, the direction of the radiating fins 5 is vertical to the side surface of the groove 2, the outer side of the radiating fin 5 is fixed by fixing pieces 6, and the fixing pieces 6 are arranged on two sides of the groove 2.

As shown in fig. 2, the groove 2 is linear, the groove 2 is recessed downward relative to the tube plate body 1, and the periphery of the upper end of the groove 2 is connected to the tube plate body 1. The shape of stationary blade 6 is L shape, stationary blade 6 is equipped with a plurality of, arranges in proper order in the outside of fin 5. A rectangular space is formed between the fixing piece 6 and the groove 2, and the radiating fin 5 is fixed between the fixing piece 6 and the groove 2.
