Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.
[0026] As Figures 1-2 shown, the present application provides a heat exchanger for thermal power, comprising a base 1, which is a support part of the heat exchanger, a distributor 9 is fixedly installed on one side of the base 1 through a flange, the inside of the distributor 9 is hollowly arranged, and the distributor 9 is suitable for distributing the fluid entering the distributor 9, so as to facilitate the heat exchange;
[0027] A shell 12 is fixedly installed on one side of the distributor 9 through a flange, the shell 12 is a main part of the heat exchanger, the inside of the shell 12 is hollowly arranged and communicates with the inside of the distributor 9, an end cover 10 is fixedly installed on the side of the shell 12 away from the distributor 9 through a flange, the end cover 10 is fixedly connected with the base 1 through a flange, and the inside of the end cover 10 is hollowly arranged and communicates with the inside of the shell 12, and the heat exchange operation is carried out in the inside of the distributor 9, the shell 12 and the end cover 10;
[0028] A distribution plate 11 is fixedly installed in the inner cavity of the distributor 9, which divides the inside of the distributor 9 into two groups of chambers of the same size, which are defined as a first chamber close to the base 1 and a second chamber away from the base 1 for the convenience of explanation, and the first pipe 2 is fixedly installed at the lower end of the distributor 9 and communicates with the first chamber, and the second pipe 3 is fixedly installed at the upper end of the distributor 9 and communicates with the second chamber; Figure 2
[0029] At least two groups of baffle plates 8 are fixedly installed in the shell 12, the baffle plates 8 can be semicircular plates and are arranged in a staggered manner, so that the fluid in the shell 12 needs to alternately flow around the baffle plates 8 when flowing, so that the flow trajectory of the fluid in the shell 12 can be changed by the baffle plates 8, the turbulent flow speed of the fluid is strengthened, and the heat transfer efficiency is improved;
[0030] As Figure 2 shown, a honeycomb plate is fixedly installed in the shell 12, a plurality of through holes are formed in the honeycomb plate, and a plurality of tube bundles 7 are arranged in the shell 12, the tube bundles 7 penetrate the baffle plates 8 and are fixedly connected with the honeycomb plate, so that the fluid in the distributor 9 can only enter the tube bundles 7 through the distributor 9 and reach the other end of the distributor 9 through the tube bundles 7, and the fluid in the shell 12 cannot enter the distributor 9, so that there are two kinds of fluids in the tube bundles 7 and the shell 12, so as to realize the exchange of thermal energy;
[0031] As Figure 1 shown, a third pipe 4 and a fourth pipe 5 are also fixedly installed on the two sides of the shell 12, respectively, to facilitate the fluid to enter the shell 12;
[0032] When the heat energy exchange is carried out, the staff only needs to inject the first liquid into the distributor 9 through the second pipe 3, the first liquid enters the second chamber and flows into the pipe bundle 7, and at the same time, the staff injects the second liquid into the shell 12 through the third pipe 4, the second liquid flows to the other end of the shell 12 through the baffle 8, when the first liquid and the second liquid reach the same position, if there is a certain temperature difference between the first liquid and the second liquid, the heat energy exchange is carried out at this time, and finally the first liquid passes through the pipe bundle 7 to reach the first chamber and flows out from the first pipe 2, and the staff can extract the second liquid through the fourth pipe 5, so as to realize the complete heat energy exchange;
[0033] However, since the shell 12 is usually designed in one piece, when the heat exchanger needs to be repaired due to damage inside the heat exchanger, the entire shell 12 needs to be disassembled, in order to solve this problem, as shown in Figure 1 、 Figures 3-5 , a repair assembly 6 is arranged on the shell 12, in the present application, the shell 12 can be split into at least two sections, and the split shells 12 are connected through the fixedly installed repair assembly 6;
[0034] The repair assembly 6 includes two groups of side rings 61, in order to ensure the sealing of the split shell 12, in the present application, the side ring 61 is fixedly connected to the shell 12 through a flange, and a sealing part 62 is fixedly installed on the side corresponding to the side ring 61, and the sealing part 62 is integrally arranged with the side ring 61;
[0035] As shown in Figures 4-5 , in order to facilitate maintenance, a notch is formed on the sealing part 62, the position of the notch is fixedly installed with a repair part 63 through a flange, and the repair part 63 is fixedly installed with the sealing part 62 and the side ring 61, so as to ensure the sealing of the repair part 63;
[0036] As shown in Figure 5 , first sliding grooves 66 are formed on both sides of the repair part 63, and a maintenance opening is formed on the repair part 63, the maintenance opening penetrates the repair part 63, and the maintenance opening is communicated with the first sliding grooves 66, maintenance plates 67 are symmetrically arranged at the position of the maintenance opening, the maintenance plates 67 are slidingly connected with the first sliding grooves 66, the side corresponding to the maintenance plates 67 is integrally provided with a push-pull part 64, and a non-slip coating is applied in the first sliding grooves 66, it should be noted that since the maintenance plates 67 can slide, sealing gaskets are arranged on the side corresponding to the push-pull part 64, when the push-pull parts 64 are close to each other, the sealing gaskets are close to each other, so as to reduce the heat loss as much as possible, and sealing gaskets are fixedly installed on the upper and lower ends of the inner wall of the maintenance opening, so as to ensure the sealing condition of the shell 12 without affecting the use of the maintenance plates 67;
[0037] In the initial state, the heat exchanger does not need to be repaired, and the maintenance plates 67 are attached to each other. When the inside of the shell 12 needs to be repaired, the staff only needs to pull the push-pull part 64, and the maintenance plates 67 slide away from each other. At this time, the maintenance opening can be opened to repair the inside of the shell 12.
[0038] In the present application, reference is made to Figures 1-5 Each set of maintenance assemblies 6 is provided with a maintenance part 63. In use, multiple sets of maintenance parts 63 can be provided to repair different positions on the shell 12. The maintenance part 63 and the remaining parts are fixedly installed through flanges to ensure the sealing condition of the shell 12.

The locking bolts 68 lock the push-pull part 64 through threads. Locking nuts 65 are threadedly connected to the other end of the locking bolts 68. One side of the locking nut 65 is in contact with the push-pull part 64. Thus, the two maintenance plates 67 are locked. When the inside of the shell 12 needs to be repaired, the locking nut 65 is removed from the locking bolt 68, and the locking bolt 68 is removed from the screw hole. Finally, the maintenance plates 67 are manually separated.
[0040] As described above, when the inside of the heat exchanger needs to be repaired, the maintenance assemblies 6 are provided. The shell 12 does not need to be completely disassembled. The staff first determines the damaged position and then reaches the maintenance part 63 according to the position. Then, the locking bolt 68 and the locking nut 65 are twisted off. The maintenance plates 67 can be manually separated. The maintenance opening is opened to repair the inside of the heat exchanger. The maintenance part 63 can be provided with multiple sets according to the actual situation, so that the compatibility of the maintenance assemblies 6 is higher.
