[0002] As a key heat transfer equipment, heat exchanger plays a vital role in industrial production. Its diversity of types and structures enables it to adapt to various application scenarios and needs. It is widely used in various industrial fields. Its main function is to transfer heat from high-temperature fluid to low-temperature fluid to meet the needs of process conditions and improve energy utilization.

[0003] In the prior art, a heat exchanger is generally provided with multiple inlets and outlets for connecting to other external equipment. However, due to the lack of protective mechanisms on the inlets and outlets, the inlets and outlets are generally exposed during the transportation and movement of the heat exchanger. As a result, foreign matter can enter the heat exchanger through the inlets or outlets, affecting the normal use of the heat exchanger in the later stage. Utility Model Content

The bracket 610 is fixedly mounted on the outer periphery of the same side material tube 2 away from the side of the cylinder 3. The bracket 610 is installed with a connecting plate 62 on the side away from the cylinder 3 through a pin 65. The connecting plate 62 is fixedly mounted with a protective plate 63 on one end away from the bracket 610. The connecting plate 62 is fixedly mounted with a mounting shaft 68 on the side close to the cylinder 3. The connecting plate 62 is fixedly mounted with a mounting rod 69 on the end away from the protective plate 63. The same group of mounting rods 69 and the mounting shaft 68 are symmetrically rotated and mounted with mounting brackets 67. The same side mounting brackets 67 are fixedly mounted with a return spring 66 on the side close to each other. The protective plate 63 is fixedly mounted with a limit plate 612 on the side away from the connecting plate 62, and the surface of the limit plate 612 A limiting groove 611 is provided, and a notch 61 is provided at the top edge of the material tube 2. A limiting frame 615 is fixedly installed just below the notch 61. A card plate 613 is slidably installed in the middle of the limiting frame 615. Compression springs 614 are provided on both sides of the card plate 613. The card plate 613 and the limiting plate 612 are wedge-shaped on the side close to each other. During the transportation of the heat exchanger, the staff uses the auxiliary handle 64 to close the protective plate 63. At this time, the limiting plate 612 will be inserted into the notch 61. Since the surfaces of the limiting plate 612 and the card plate 613 are provided with wedge-shaped surfaces, the card plate 613 will move toward the limiting frame 615, and the compression spring 614 will be compressed. When the card plate 613 is aligned with the limiting groove 611, the compression spring 614 will press the card plate 6 13 is reset, and then the card plate 613 will be clamped in the limiting groove 611, thereby completing the limiting of the protective plate 63. Since the size of the protective plate 63 is adapted to the material pipe 2, the four material pipes 2 can be blocked to prevent foreign matter from entering the heat exchanger through the material pipe 2 during transportation, thereby affecting the normal operation of the heat exchanger. Moreover, when the material pipe 2 is connected to the external equipment, the card plate 613 is pulled again. At this time, the limiting plate 612 loses its limit, and the reset spring 66 will bounce the protective plate 63, so that the material pipe 2 can be connected to the external equipment. Moreover, the protective plate 63 is connected to the bracket 610 through the reset spring 66 and the connecting plate 62, which can increase the expansion angle of the protective plate 63 and will not affect the connection between the material pipe 2 and the external equipment.

[0023] A vent pipe 7 is fixedly installed on the upper part of the outer periphery of the pipe box 1 on one side, and a drain pipe 5 is fixedly installed on the lower part of the outer periphery of the pipe box 1 on the other side. A support 4 is fixedly installed on the middle part of the outer periphery of the cylinder 3, and a gasket is provided at the bottom end of the support 4. A plurality of evenly distributed partitions 8 are fixedly installed on the outer periphery of the heat exchange tube 9, and a plurality of evenly distributed pull rods 10 are provided in the partition 8. A U-shaped bend is provided on one end of the heat exchange tube 9, and a plurality of evenly distributed elastic gaskets 11 are provided between adjacent U-shaped bends. By providing the elastic gaskets 11, the adjacent heat exchange tubes 9 in the cylinder 3 can be fixed to avoid instability and shaking of the heat exchange tubes 9 during use, which affects their normal use. An auxiliary handle 64 is fixedly installed in the middle of the side of the protective plate 63 away from the limit plate 612.

[0024] During actual use, the staff inserts the limit plate 612 on the protective plate 63 into the slot 61. At this time, the card plate 613 cooperates with the compression spring 614 and the limit slot 611 to limit and fix the protective plate 63, so that the protective plate 63 can block the material pipe 2, which can prevent foreign matter from entering the heat exchange tube 9 and affecting the normal use of the heat exchange tube 9 in the later stage. Moreover, when the material pipe 2 needs to be connected to external equipment, the card plate 613 is pulled. At this time, the limit plate 612 loses its limit, and the reset spring 66 can automatically open the protective plate 63. Then the staff can use fixing bolts to connect the heat exchanger to the external equipment.
