Description

Technical Field

[0001] The utility model relates to a cold exchanger, in particular to a high-efficiency refrigeration cold exchanger applied in the field of ice-making equipment. Background Art

[0002] An ice maker is a mechanical device that generates ice by cooling water through a refrigeration system. It uses a refrigeration system and water as a carrier to condense water into ice. Cold exchange equipment is used in the ice-making process. When heat exchange is performed, the liquid will first enter the water collecting box, and then pass through the water collecting box into multiple heat exchange tubes connected to it for cold exchange operation.

[0003] The water collecting boxes in the existing cold exchangers are mostly in the form of round tubes or square tubes. When welding the heat exchange tubes and the water collecting box, the contact surface of the round tube is small, which is not convenient for welding the heat exchange tubes and the round tubes, and may even cause water leakage in the pipes after welding. Although the square tube is easy to weld, the pressure bearing capacity of the square tube is weaker than that of the round tube, and the pressure shock during use is larger. Both types of pipes are inconvenient to operate, which may lead to a decrease in the refrigeration effect of the cold exchanger and a shortened service life of the water collecting box. Utility Model Content

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that the water collecting boxes in the existing cold exchangers are mostly circular pipes or square pipes, but the circular pipes are not convenient for welding and water leakage may occur, and the square pipes have weak pressure bearing capacity, which leads to a decrease in the cooling effect of the cold exchanger and a shortened service life of the water collecting box.

[0005] To solve the above problems, the utility model provides a high-efficiency refrigeration exchanger, including four cross beams, two end columns are commonly fixedly connected between the upper and lower cross beams, and the upper and lower cross beams are fixedly connected with the middle column through a connecting plate, a middle longitudinal beam and two end longitudinal beams are commonly fixedly connected between the front and rear cross beams, a plurality of clamping plates 2 are commonly fixedly connected between the two end longitudinal beams on the left side, and a plurality of clamping plates 1 are commonly fixedly connected between the two end longitudinal beams on the right side, a U-shaped heat exchange tube row is commonly fixedly connected between the clamping plates 1 and 2, both ends of the heat exchange tube row are fixedly connected with a water collecting box, the water collecting box includes a tube sheet fixedly penetrated by the ends of the heat exchange tube row, a bending buckle plate is fixedly connected to the inner wall of the tube sheet, the front and rear ends of the tube sheet are fixedly connected with a blocking plate, the ends of the two blocking plates away from each other are fixedly connected with a reinforcing rib plate, the left end of the bending buckle plate is fixedly connected with a connecting pipe, and a temperature measuring tube is fixedly penetrated in the connecting pipe of one of the water collecting boxes.

[0006] In the above-mentioned high-efficiency refrigeration cooler, the U-shaped tube sheet is used to facilitate the welding of the heat exchange tube row tubes, and then the force points are dispersed through the curved bending buckle plate, and the tube sheet and the bending buckle plate are sealed with a plugging plate and a reinforcing rib plate to improve the pressure-bearing capacity of the water collecting box, thereby effectively reducing pressure shock, effectively avoiding the occurrence of water leakage, and improving the cooling effect of the cooler.

[0007] As a further improvement of the present application, a flange is fixedly sleeved on the outer surface of the connecting pipe, and an externally threaded pipe joint is fixedly connected to the outer surface of the connecting pipe, and the connecting pipe, the bending buckle plate and the externally threaded pipe joint are connected.

[0008] As a further improvement of the present application, adjacent end longitudinal beams and cross beams are fixedly connected with tie angle steels, and the angle between the end longitudinal beams and the tie angle steels is forty-five degrees.

[0009] As a further improvement of the present application, the cross section of the tube sheet is U-shaped, and a plurality of fixing holes are drilled on the inner wall of the tube sheet, and the inner diameter of the fixing holes is consistent with the diameter of the heat exchange tube row.

[0010] As another improvement of the present application, the bending buckle plate includes two rectangular blocks and an isosceles trapezoidal plate fixedly connected to the two rectangular blocks. The ends of the two rectangular blocks that are away from each other are fixedly connected to the inner wall of the tube plate, and the angle between the isosceles trapezoidal plate and the rectangular blocks is one hundred and thirty-five degrees.

[0011] As another improvement of the present application, a pressure gauge is fixedly connected to the front end of the blocking plate, and the pressure gauge is connected to the external controller signal.

[0012] To summarize, in actual application, water flows through a connecting pipe into a water collecting box connected to it, and then enters the heat exchange tube row pipe through the water collecting box for heat exchange operation, and then enters another water collecting box and is discharged through another connecting pipe. The heat exchange tube row pipe is supported and limited by the first and second clamps, and multiple cross beams, middle columns, end columns, end longitudinal beams and middle longitudinal beams provide stable support for the overall equipment. The U-shaped tube sheet is convenient for welding the heat exchange tube row pipe, and then the force points are diverged by the curved bending buckle plate. The tube sheet and the bending buckle plate are sealed with a plugging plate and a reinforcing rib plate to improve the pressure bearing capacity of the water collecting box, thereby effectively reducing pressure shock, effectively avoiding the occurrence of water leakage, and improving the cooling effect of the cooler.

DETAILED DESCRIPTION

[0021] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0022] The first implementation method:

[0024] Figure 4 and Figure 5It is shown that: an intermediate longitudinal beam 14 and two end longitudinal beams 12 are fixedly connected between the front and rear cross beams 8, both ends of the heat exchange tube row tube 10 are fixedly connected with a water collecting box, the water collecting box includes a tube sheet 5 fixedly penetrated by the ends of the heat exchange tube row tube 10, the inner wall of the tube sheet 5 is fixedly connected with a bending buckle plate 4, the front and rear ends of the tube sheet 5 are fixedly connected with a plugging plate 16, the ends of the two plugging plates 16 that are far away are fixedly connected with a reinforcing rib plate 17, the left end of the bending buckle plate 4 is fixedly connected with a connecting pipe 2, a temperature measuring tube 18 is fixedly penetrated in the connecting pipe 2 of one of the water collecting boxes, the temperature measuring tube 18 can detect the water temperature inside the connecting pipe 2 of the water outlet, the adjacent end longitudinal beams 12 and the cross beam 8 are fixedly connected with a tie angle steel 13, and the end longitudinal beams 12 and the tie angle steel 13 are fixedly connected. The angle between the rib angle steels 13 is forty-five degrees, and the cross-section of the tube sheet 5 is U-shaped. The U-shaped tube sheet 5 is convenient for welding the heat exchange tube row tube 10, and then the force points are diverged through the bending buckle plate 4 with a curvature, and a plurality of fixing holes are opened on the inner wall of the tube sheet 5.
