[0002] A cooler is a type of heat exchange equipment used to cool fluids. It typically uses water or air as a coolant to remove heat. They can be mainly classified into shell-and-tube coolers, plate coolers, and air-cooled coolers. Coolers are widely used heat exchange devices in industries such as metallurgy, chemical engineering, energy, transportation, light industry, and food processing.

The upper and lower ends of the cylinder are sealed by an upper tube box and a lower tube box, respectively. An upper tube plate is provided between the upper tube box and the cylinder, and a lower tube plate is provided between the lower tube box and the cylinder. Heat exchange tubes that allow gas to pass through are provided inside the cylinder. The upper and lower ends of the heat exchange tubes pass through holes in the upper and lower tube plates, respectively, and communicate with the upper and lower tube boxes, respectively. The cylinder interior is provided with... The cylinder has a number of baffles fixedly connected and staggered on its left and right inner walls. The upper tube box has an air inlet on its side wall and the lower tube box has an air outlet on its side wall. One end of the cylinder has a circulating water inlet located on the side where the lowermost baffle is fixed to the cylinder. The other end of the cylinder has a circulating water outlet located on the side where the uppermost baffle is fixed to the cylinder. The heat exchange tube has a number of bends in its middle section. The bends are arranged alternately on both sides with the central axis of the heat exchange tube as the reference.

[0006] This utility model also includes a blow-off pipe for blowing out impurities inside the cylinder, the blow-off pipe being located in the lower end pipe box.

[0007] This utility model also includes a spacer tube fixedly connected to the baffle plate, and the distance between two adjacent baffle plates is 105 mm.

[0008] The lower end of the lower pipe box of this utility model is provided with a mounting seat for fixing the cylinder. The mounting seat includes a seat body adapted to the lower pipe box. The lower end of the seat body has an outwardly extending extension around its perimeter. An inclined reinforcing rib is provided between the extension and the seat body.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Compared with the existing technology where the heat exchange efficiency of the cooler is not high and the required cooling effect is not achieved, this utility model improves the heat exchange efficiency and achieves the required cooling effect by setting up a number of staggered baffles to increase the residence time of circulating water in the cylinder and having a number of bends in the middle of the heat exchange tube to increase the residence time of gas in the cylinder. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 As shown in this embodiment, a cooler for improving heat exchange efficiency includes a vertically arranged hollow cylindrical body 1. The upper and lower ends of the cylindrical body 1 are sealed by an upper tube box 2 and a lower tube box 3, respectively. An upper tube plate 21 is provided between the upper tube box 2 and the cylindrical body 1, and a lower tube plate 31 is provided between the lower tube box 3 and the cylindrical body 1. The interior of the cylindrical body 1 is provided with heat exchange tubes 4 that allow gas to pass through. The upper and lower ends of the heat exchange tubes 4 pass through holes in the upper tube plate 21 and the lower tube plate 31, respectively, and communicate with the upper tube box 2 and the lower tube box 3. The interior of the cylindrical body 1 is provided with a plurality of baffles 5 that are fixedly connected to the left and right inner walls of the cylindrical body 1 and arranged alternately. The side wall of the upper tube box 2 is provided with an air inlet 22, and the side wall of the lower tube box 3 is provided with... The cylinder 1 has an air outlet 32. One end of the cylinder 1 is provided with a circulating water inlet 11, which is located on the side where the lowest baffle 5 is fixed to the cylinder 1. The other end of the cylinder 1 is provided with a circulating water outlet 12, which is located on the side where the uppermost baffle 5 is fixed to the cylinder 1. The heat exchange tube 4 has a number of bends 41 in the middle. The bends 41 are arranged alternately to bend to both sides with the central axis of the heat exchange tube 4 as a reference. In this embodiment, by providing a number of baffles 5 arranged in an alternating manner, the residence time of the circulating water in the cylinder 1 is increased. The number of bends 41 in the middle of the heat exchange tube 4 increases the residence time of the gas to be cooled in the cylinder 1, thereby doubly improving the heat exchange efficiency and achieving the required cooling effect.

[0014] This embodiment also includes a blow-off pipe 6 for blowing out impurities inside the cylinder 1. The blow-off pipe 6 is located in the lower end tube box 3. The function of the blow-off pipe 6 is to blow out impurities inside the cylinder 1, thereby improving heat exchange efficiency.

[0015] This embodiment also includes a spacer tube 51 fixedly connected to the baffle 5, with a spacing of 105 mm between two adjacent baffles 5; the appropriate spacing ensures the best heat exchange effect.

[0016] In this embodiment, the lower end of the lower end pipe box 3 is provided with a mounting seat 7 for fixing the cylinder 1. The mounting seat 7 includes a seat body 71 adapted to the lower end pipe box 3. The lower end of the seat body 71 has outwardly extending extensions 72 around its perimeter. An inclined reinforcing rib 73 is provided between the extensions 72 and the seat body 71. The function of the mounting seat 7 is to reinforce the lower end pipe box 3, thereby strengthening the stability of the cylinder 1.
