[0022] like Figures 1 to 4As shown, a heat exchanger with an easily removable shell provided by an embodiment of the utility model comprises a base plate 1, a fixing plate 2, a fixing rod 3, a protective shell 4 and a positioning block 5. The top of the base plate 1 is fixedly connected to the bottom of the fixing plate 2, and the left and right sides of the fixing rod 3 are both extended to the left and right sides of the fixing plate 2. The top of the base plate 1 is movably connected with the protective shell 4, and the front and rear sides of the protective shell 4 are both fixedly connected with the positioning blocks 5. A positioning cavity 6 is provided inside the front positioning block 5, and two adjusting mechanisms 7 and a positioning mechanism 8 are provided inside the positioning cavity 6. The opposite sides of the two adjusting mechanisms 7 are both extended to the top and the bottom of the positioning block 5, and the positioning mechanism 8 is used in conjunction with the fixing plate 2.

[0023] refer to Figure 3 The adjustment mechanism 7 includes a moving rod 701, a fixed column 702 and a bent rod 703. The opposite sides of the two moving rods 701 penetrate the top and bottom of the positioning block 5, and the opposite sides of the two moving rods 701 penetrate the interior of the positioning block 5. The front side of the moving rod 701 is fixedly connected to the rear side of the fixed column 702, and the front side of the fixed column 702 penetrates to the front side of the bent rod 703. The bent rod 703 is movably connected to the interior of the positioning cavity 6 through a rotating shaft.

[0024] The above scheme is adopted: by setting the adjustment mechanism 7, the movable rod 701 can be pulled, and the movable rod 701 drives the fixed column 702 to move, and the angle of the bent rod 703 can be adjusted through the surface of the fixed column 702, so that the staff can use it conveniently.

[0025] refer to Figure 3 The positioning mechanism 8 includes a vertical rod 801, a positioning rod 802 and a tension spring 803. The surface of the vertical rod 801 contacts the surface of the bent rod 703. The left side of the vertical rod 801 is fixedly connected to the right side of the tension spring 803. The left side of the tension spring 803 is fixedly connected to the inner wall of the positioning cavity 6. The tension spring 803 is sleeved on the surface of the positioning rod 802. The right side of the positioning rod 802 is fixedly connected to the left side of the vertical rod 801. The left side of the positioning rod 802 passes through the interior of the fixed plate 2.

[0026] By adopting the above solution, the positioning mechanism 8 is provided, so that the protective shell 4 can be stably fixed on the surface of the fixing plate 2 to prevent it from loosening during use.

[0027] refer to Figure 3 and Figure 4 A fixing groove 9 is provided on the surface of the fixing plate 2, and the positioning rod 802 is in close contact during insertion.

[0028] By adopting the above solution, by providing the fixing groove 9, the positioning rod 802 can be accurately inserted into the fixing groove 9 during plugging and fixing, so as to be stably fixed.

[0029] refer to Figure 3A limiting groove 10 is opened inside the positioning cavity 6 , and the vertical rod 801 moves along the opening path of the limiting groove 10 .

[0030] By adopting the above solution, by providing the limiting groove 10, the vertical rod 801 can be moved according to the moving direction provided by the limiting groove 10, thereby ensuring the normal use of the structure.

[0031] refer to Figure 3 A travel groove 11 is provided on the front side of the curved rod 703 , and the travel groove 11 is used in conjunction with the fixed column 702 .

[0032] By adopting the above solution, by providing the travel groove 11, the fixed column 702 can be moved, and its moving direction and travel can be limited to prevent the fixed column 702 from exceeding the travel during use and causing structural damage.

[0033] refer to Figure 3 The interior of the positioning cavity 6 is fixedly connected to a limiting block 12 , and the limiting block 12 is sleeved on the surface of the moving rod 701 .

[0034] By adopting the above solution, the limit block 12 is provided to limit the moving direction and stroke of the moving rod 701, thereby ensuring the normal operation of the overall structure.

[0035] The working principle of this utility model:

[0036] When in use, the moving rod 701 is pulled to the opposite side at the same time, and the moving rod 701 drives the fixed column 702 to move to the opposite side. The surface of the fixed column 702 squeezes the inner wall of the travel groove 11 so that the two bent rods 703 rotate to the opposite side with the rotating shaft as the center. During rotation, the surface of the bent rod 703 squeezes the surface of the vertical rod 801 so that the vertical rod 801 moves to the right. The vertical rod 801 drives the positioning rod 802 to move to the right according to the moving trajectory provided by the limiting groove 10, and at the same time stretches the tension spring 803, so that the positioning rod 802 moves to the inside of the positioning cavity 6. At this time, the protective shell 4 can be pulled upward and taken out for daily maintenance. After completion, the protective shell 4 is put back in, the moving rod 701 is released, and the bent rod 703 is reinserted into the inside of the fixed groove 9 by the return force of the tension spring 803.

[0037] In summary, the heat exchanger with an easily removable shell solves the problem that when the weather temperature is low, the temperature difference between the inside and outside of the shell of the heat exchanger is large during operation, and a shell needs to be set on its surface to prevent the rapid loss of heat. However, when the heat exchanger is subjected to daily maintenance and overhaul, the shell needs to be disassembled. The existing heat exchanger shells are fixed by bolts, which are inconvenient to disassemble, delay work efficiency, and are not convenient for staff to operate. In order to facilitate staff to disassemble the shell, a heat exchanger with an easily removable shell is proposed, which is convenient for staff to operate when the shell is disassembled, simplifies operation, and is convenient for maintenance.
