Heat exchanger

[0013] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.

[0014] See Figure 1-2 , A heat exchanger, comprising a cooling tank 1, a longitudinal baffle 7 and an upper end cover 14; the cross section of the cooling tank 1 is square, and four sets of tubes 8 are arranged in the cooling tank 1 along the horizontal and transverse intervals. Each group of tube 8 is provided with at least two along the horizontal and longitudinal direction. The tube 8 is spiral. The design of the spiral tube increases the pipe stroke of the tube 8 and improves the heat exchange effect. Among them, each adjacent two sets A longitudinal baffle 7 is provided between the tubes 8, the longitudinal baffle 7 on the left is provided between the first group of tubes 8 and the second group of tubes 8, and the middle longitudinal baffle 7 is provided in the second Between the group tube 8 and the third group of tubes 8, the right longitudinal baffle 7 is arranged between the third group of tubes 8 and the fourth group of tubes 8, and the longitudinal baffle 7 is arranged on the cooling tank. 1, and the longitudinal baffle 7 divides the inside of the cooling tank 1 into four cooling turbulence zones 15. The open ends of the two adjacent longitudinal baffles 7 are respectively arranged at two opposite ends, and the left longitudinal baffle The open ends of the plate 7 and the longitudinal baffle 7 on the right side are set at the lower end, and the open end of the longitudinal baffle 7 in the middle is set at the upper end. The longitudinal baffle 7 causes the refrigerant to form a turbulent flow in the cooling tank 1. The heat exchange effect is good; in addition, an upper end cover 14 is provided above the cooling tank body 1, a lower end cover 6 is provided below the cooling tank body 1, and 12 upper fixing holes are evenly distributed on four sides of the upper end of the cooling tank body 1. 10. The four sides of the lower end of the cooling tank body 1 are provided with 12 lower fixing holes 3, the four sides of the upper end cover 14 are provided with 12 upper mounting holes 11, and the four sides of the lower end cover 6 are provided with 12 The lower mounting holes 4, the upper mounting holes 11 and the upper fixing holes 10 are arranged in one-to-one correspondence, and the lower mounting holes 4 and the lower fixing holes 3 are arranged in one-to-one correspondence. The upper end cover 14 and the lower end cover 6 can be installed with the cooling tank 1 through bolts Together, a sealing ring is provided between the upper end cover 14 and the lower end cover 6 and the cooling tank 1; the upper end cover 14 is provided with two sets of partitions 16 which divide the upper end cover cavity into three chambers 5 , Each chamber 5 communicates with the upper end of the tube 8, wherein the first chamber 5 of the upper end cover 14 communicates with the first group of tubes 8, and the second chamber 5 of the upper end cover 14 communicates with the second and third groups The column tube 8 communicates, the third chamber 5 of the upper end cover 14 communicates with the fourth group of column tubes 8, a set of partitions 16 are provided in the lower end cover 6, and the partitions 16 divide the lower end cover cavity into two left and right chambers 5, The chamber 5 on the left side of the lower end cover 6 communicates with the lower ends of the first and second sets of tubes 8, and the chamber 5 on the right side of the lower end cover 6 communicates with the lower ends of the third and fourth sets of tubes 8; The right side of the cooling tank body 1 is provided with a shell side outlet 9; the left side of the cooling tank body 1 is provided with a shell side inlet 2; the left side chamber 5 of the upper end cover 14 is provided with a tube side outlet 13; The right side chamber 5 is provided with a tube pass inlet 12; when working, the heat medium enters the fourth group of tubes 8 from the tube pass inlet 8 and enters the third group of tubes 8 through the right side chamber 5 of the lower end cover 6, and then Then the second chamber 5 of the upper end cover 14 enters the left chamber 5 of the lower end cover 6 through the second set of tubes 8 and then enters the first chamber 5 of the upper end cover 14 through the first set of tubes 8 , And finally the heat medium flows out of the tube side exit 13, and the refrigerant flows from the cooling The shell side inlet 2 of the tank 1 enters the cooling tank 1, and the refrigerant passes through the baffle of the longitudinal baffle 7, and finally the refrigerant flows out of the shell side outlet 9. The spiral tube 8 makes the heat between the heat medium and the refrigerant The exchange contact area is increased and the heat exchange effect is improved.

[0015] The above description of the present invention has only been made with examples, but the present invention is not limited to the above-mentioned dimensions and appearance illustrations, and should not constitute any limitation of the present invention. As long as any improvements or modifications made to the present invention fall within the protection scope of the claims of the present invention.
