Problems solved by technology
[0004] At present, the installation space of the sleeve-type heat exchanger is limited. On the one hand, in order to achieve a certain heat exchange area, the sleeve-type heat exchanger needs to connect multiple segments of sleeves with 180-degree bends. The concentric circular tubes are generally covered by shell side Tube side, tube side welding and disassembly are troublesome, installation and maintenance are inconvenient; on the other hand, sleeve-tube heat exchangers generally have a fixed volume, and expansion or reduction of volume must be redesigned and manufactured, and expansion or reduction is inconvenient

Embodiment Construction
[0026] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0027] Such as Figure 4 As shown, a matrix casing heat exchanger includes a plurality of casing groups of the same size connected in parallel to form a matrix shape of 7 rows and 10 columns, and also includes an inlet pipe 3, an outlet pipe 4, a refrigerant input pipe 5 and Refrigerant output pipe 6 and fixing bracket 7. figure 1 It is a schematic structural diagram of a single casing group of a matrix tube-in-tube heat exchanger, each casing group includes seven first casings 1, six second casings, two end casings 8 water inlet 821, and water outlet 822 , a refrigerant outlet 811 and a refrigerant inlet 812. The water inlet 821 and the water outlet 822 are respe...

The invention relates to a matrix-type sleeve heat exchanger. The matrix-type sleeve heat exchanger is characterized in that the matrix-type sleeve heat exchanger comprises a plurality of sleeve groups which are connected in parallel and are the same in size, each sleeve group comprises a plurality of first sleeves and a plurality of second sleeves, the first sleeves and the second sleeves are connected in series and located in the same plane, the first sleeves are straight sleeves, the second sleeves are 180-degree bent sleeves, the second sleeves comprise second shell sides and second pipe sides, the pipe diameter of the second pipe sides is smaller than the pipe diameter of the second shell sides, each second pipe side extends linearly inside the corresponding second shell side from one side of the second shell side to the outer portion of the second shell side, then is bent by 180 degrees to reach the outer portion of the other end of the second shell side in the straight line direction and further extends linearly to enter the inner portion of the second shell side until return to the other end of the second shell side; each sleeve group comprises a water inlet, a water outlet, a refrigerant inlet and a refrigerant outlet. The matrix-type sleeve heat exchanger is low in cost, convenient to assemble and disassemble and can further achieve the effect of changing the size of heat exchanging area by increasing or reducing the number of the sleeve groups and the number of the first sleeves in the sleeve groups.
Description
technical field [0001] The invention relates to a heat exchanger, in particular to a matrix casing heat exchanger. Background technique [0002] Heat exchanger is a general-purpose equipment widely used in chemical industry, petroleum, electric power, medicine, metallurgy, refrigeration and other industries. Classified according to the shape and structure of its heat transfer surface, it can be divided into tube type, plate type and other heat exchangers, and tube type heat exchangers can be divided into coil heat exchangers, casing heat exchangers and tube shells heat exchanger etc. [0003] The casing heat exchanger is a common heat exchanger. Its basic structure is two round tubes of different diameters. The tube with a smaller diameter (tube side) is sleeved inside the tube with a larger diameter (shell side). Two temperatures Different fluids flow in reverse or in the same direction in the inner tube and the outer tube respectively, and exchange heat through the tube ...
