Embodiment

[0036] Further optimization of the first embodiment is specifically as shown in Figures 3-6 .

[0037] The fixing frame 3 is internally provided with a center groove 10, the internal positioning mechanism includes plug-in blocks 12, two plug-in blocks 12 are symmetrically installed at the bottom of the center groove 10, the surfaces of the plug-in blocks 12 penetrate through the fixing frame 3, two plug-in grooves 15 are symmetrically formed in the inner wall of the clamping groove 4, the two plug-in blocks 12 are matched with the two plug-in grooves 15 respectively, and the plug-in blocks 12 are movably plugged into the plug-in grooves 15.

[0038] After the plug-in blocks 12 are inserted into the plug-in grooves 15, the end portions of the baffle plate 2 are supported and positioned, the movement of the baffle plate 2 in the front-rear direction is limited, the baffle plate 2 is prevented from moving due to factors such as fluid impact or equipment vibration, the stability of the connection between the baffle plate 2 and the fixing frame 3 is enhanced, the service life of the heat exchange assembly is prolonged, in the installation process, the plug-in matching mode is simple and direct, so that an operator can quickly position and install the baffle plate 2 and the fixing frame 3, the installation difficulty is reduced, the installation efficiency is improved, and the installation time and labor cost are reduced.

[0039] A trapezoidal block 11 is arranged at the center of the center groove 10, the trapezoidal block 11 is between the two plug-in blocks 12, one end of the plug-in block 12 close to the trapezoidal block 11 is provided as an inclined surface, and the end surface of the trapezoidal block 11 is slidably matched with the inclined surface of the plug-in block 12.

[0040] When the trapezoidal block 11 is pushed down, due to the sliding fit between the end face of the trapezoidal block 11 and the inclined face of the plug-in block 12, as the trapezoidal block 11 descends, it will extrude the inclined face of the plug-in block 12, and this extrusion will make the plug-in block 12 move outward along the horizontal direction, and finally the plug-in block 12 is inserted into the corresponding plug-in groove 15 in the inner wall of the clamping groove 4, thereby realizing the positioning and fixing of the baffle plate 2. By operating one trapezoidal block 11, the actions of two plug-in blocks 12 can be controlled at the same time, the baffle plate 2 is quickly positioned, the installation efficiency of the baffle plate 2 is greatly improved, and the maintenance time and labor cost are reduced.

[0041] The bottom of the end face of the trapezoidal block 11 is fixedly provided with a T-shaped sliding block 14, and the surface of the inclined face is provided with a T-shaped sliding groove 13, and the T-shaped sliding block 14 is slidably installed in the T-shaped sliding groove 13.

[0042] When an upward or downward force is applied to the trapezoidal block 11, the trapezoidal block 11 moves along the vertical direction. Since the T-shaped sliding block 14 is slidably installed in the T-shaped sliding groove 13, the T-shaped sliding block 14 can only slide in the track defined by the T-shaped sliding groove 13, which enables the vertical movement of the trapezoidal block 11 to be accurately transmitted to the plug-in block 12. During the movement of the trapezoidal block 11, its end face interacts with the inclined face of the plug-in block 12, thereby making the plug-in block 12 move horizontally in the designed direction, realizing the plug-in or separation action with the plug-in groove 15 on the baffle plate 2, and completing the positioning and dismounting function of the baffle plate 2.

[0043] The top of the trapezoidal block 11 is rotatably installed with a screw 8, and the screw 8 penetrates the fixing frame 3 through the threaded face;

[0044] According to the principle of threaded transmission, when the screw 8 rotates, it will move linearly along the threaded direction. Since the screw 8 is rotatably installed at the top of the trapezoidal block 11, the linear movement of the screw 8 will drive the trapezoidal block 11 to move up and down in the center groove 10, and the up and down movement of the trapezoidal block 11 will drive the plug-in block 12 to move in and out in the horizontal direction through the sliding fit between the inclined face of the trapezoidal block 11 and the plug-in block 12, thereby realizing the plug-in or separation action with the plug-in groove 15 on the baffle plate 2, so as to fix or loosen the baffle plate 2.

[0045] The external positioning mechanism includes an arc-shaped plate 6, the arc-shaped plate 6 is arranged above the clamping groove 4, the screw 8 movably penetrates the arc-shaped plate 6, and a recess groove 7 is formed in the middle end of the top of the arc-shaped plate 6, and the top of the screw 8 movably locates in the recess groove 7;

[0046] With the rotation of the screw 8, the arc-shaped plate 6 also moves in the same direction during its upward or downward movement, and the arc-shaped plate 6 is clamped to the end face of the baffle plate 2, effectively ensuring the stability of the baffle plate 2.

[0047] The four end corners of the arc-shaped plate 6 are each provided with a side plate 16.

[0048] After the arc-shaped plate 6 is lowered, the four side plates 16 can be clamped on the end face of the baffle plate 2, and the side plates 16 play a role of auxiliary positioning and reinforcement. Embodiment

[0049] Further optimization of the second embodiment is shown as follows: Figures 3-6

[0050] Two shielding plates 9 are mounted on the surface of the screw 8 close to the top, and the two shielding plates 9 are mounted inside the recessed groove 7 and the bottom of the arc-shaped plate 6.

[0051] When the screw 8 moves up and down, the two shielding plates 9 can drive the arc-shaped plate 6 to move synchronously, and the two shielding plates 9 can play a certain positioning role, so that the screw 8 is always in the appropriate position, and the arc-shaped plate 6 can accurately position the baffle plate 2 from the outside.

[0052] A cross countersunk head is arranged at the top of the screw 8.

[0053] The cross countersunk head arranged at the top of the screw 8 can be perfectly matched with a common cross screwdriver, and when it is necessary to tighten or loosen the screw 8, the maintenance personnel can quickly and accurately insert the screwdriver into the cross countersunk head groove, thereby providing great convenience for operation.

[0054] The use process of the heat exchanger with the baffle plate capable of being quickly disassembled is as follows:

[0055] Firstly, the heat exchanger 1 is placed at a suitable installation position, and the inside is cleaned of impurities and foreign matters, so that the installation environment is ensured to be clean, then the clamping groove 4 of the baffle plate 2 is aligned with the surface of the fixed frame 3, the clamping groove 4 of the baffle plate 2 is slowly sleeved on the fixed frame 3, so that the baffle plate 2 is preliminarily in contact with the fixed frame 3, then the screw 8 is screwed by using the cross screwdriver, according to the screw thread transmission principle, the screw 8 rotates and moves linearly downward along the screw thread direction, because the screw 8 is rotationally connected with the trapezoidal block 11, so that the trapezoidal block 11 is driven to move downward in the center groove 10, in the descending process of the trapezoidal block 11, the T-shaped sliding block 14 at the end face of the trapezoidal block 11 slides in the T-shaped sliding groove 13 on the inclined surface of the insertion block 12, at the same time, the end face of the trapezoidal block 11 extrudes the inclined surface of the insertion block 12, the insertion block 12 extruded in the horizontal direction moves outward, finally the insertion block 12 is inserted into the corresponding insertion groove 15 in the inner wall of the clamping groove 4, at the same time, because the screw 8 movably penetrates the arc-shaped plate 6, and the two shielding plates 9 are mounted on the surface of the screw 8 close to the top, with the descending of the screw 8, the arc-shaped plate 6 also moves downward, when the arc-shaped plate 6 is lowered to a certain position, the four side plates 16 at the end corners of the arc-shaped plate 6 are clamped on the end face of the baffle plate 2, the bottom of the arc-shaped plate 6 is attached to the end face of the baffle plate 2, so that the baffle plate 2 is positioned and constrained from the outside, and the stability of the baffle plate 2 is enhanced. ​
