Technical Field

[0001] This invention relates to the field of microchannel plate heat exchanger technology, and in particular to a detachable microchannel plate heat exchanger. Background Technology

[0002] The operation of gas turbines is easily affected by external temperature and humidity. Adding a microchannel plate heat exchanger in the gas turbine's intake passage allows for heat exchange and intake air heating, which can improve the unit's operating performance under partial load conditions.

[0003] Microchannel plate heat exchangers are typically fixed inside the gas turbine's intake passage using brackets. During use, they require regular maintenance, cleaning, and replacement. The microchannel plate heat exchanger uses an insert-type installation method connected to the bracket. Due to the limitations of the intake passage, it is inconvenient to remove the microchannel plate heat exchanger from inside for replacement. Furthermore, during cleaning, because the microchannel plate heat exchanger is upright inside the gas turbine's intake passage, it is difficult to clean and maintain its back side. Therefore, a removable microchannel plate heat exchanger is proposed. Summary of the Invention

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1, referring to Figures 1 to 5 This is the first embodiment of the present invention, which provides a detachable microchannel plate heat exchanger, including a heat exchange mechanism 100 and an installation mechanism 200 disposed on the heat exchange mechanism 100. The heat exchange mechanism 100 and the installation mechanism 200 are slidably connected. It also includes a support mechanism 300 disposed on the installation mechanism 200, and a connecting mechanism 400 is provided on the support mechanism 300. In this embodiment, the heat exchange mechanism 100 can be pulled out from the inside of the installation mechanism 200 by sliding and pulling, so as to be disassembled and installed. The installation mechanism 200 and the support mechanism 300 are connected. There are two connecting mechanisms 400, which are symmetrically disposed on both sides of the support mechanism 300.

[0036] The connecting mechanism 400 includes a rotating member 401 disposed on the support mechanism 300, and a fixing member 402 slidably disposed on the rotating member 401; the rotating member 401 includes a rotating plate 401a fixedly disposed on the support mechanism 300, and a first vertical groove 401b and a deflection groove 401c disposed on the rotating plate 401a; the fixing member 402 includes a connecting frame 402a, and a first support shaft 402b and a second support shaft 402c disposed on the connecting frame 402a. In this embodiment, the rotating plate 401a is fixedly installed on the outer wall surface of the support mechanism 300, and the first vertical groove 401b is arranged in a vertical state.

[0037] Specifically, the inner wall of the first vertical groove 401b and the outer wall of the first support shaft 402b are slidably connected, and the inner wall of the deflection groove 401c and the outer wall of the second support shaft 402c are slidably connected. In this embodiment, the first support shaft 402b can slide on the inner wall of the first vertical groove 401b, and the second support shaft 402c can slide on the inner wall of the deflection groove 401c.

[0038] Furthermore, the deflection groove 401c includes an arc-shaped groove 401c-1 and a second vertical groove 401c-2 disposed on the rotating plate 401a. In this embodiment, the center of the arc-shaped groove 401c-1 is located inside the first vertical groove 401b. When the second support shaft 402c is located inside the arc-shaped groove 401c-1, it can slide on the inner wall of the arc-shaped groove 401c-1 with the position of the first support shaft 402b as the center, thereby rotating the rotating plate 401a and causing the heat exchange mechanism 100 to rotate. After the heat exchange mechanism 100 rotates, it is convenient to slide the heat exchange mechanism 100 out of the installation mechanism 200.

[0039] Preferably, the second vertical groove 401c-2 and the arc groove 401c-1 are interconnected; in this embodiment, the second support shaft 402c can slide from the second vertical groove 401c-2 into the arc groove 401c-1.

[0040] In this embodiment, the second vertical groove 401c-2 and the first vertical groove 401b are arranged in parallel. By arranging the second vertical groove 401c-2 and the first vertical groove 401b in parallel, the first support shaft 402b and the second support shaft 402c can slide synchronously, so that the heat exchange mechanism 100 can have a certain sliding space, which facilitates the connection of the circulating water pipeline. Furthermore, after the second support shaft 402c slides into the second vertical groove 401c-2, it can limit the angular deflection of the rotating plate 401a.

[0041] The fixing member 402 is fixed to the top of the inner wall of the gas turbine intake passage pipe by the connecting bracket 402a. When the heat exchange mechanism 100 is installed, the rotating plate 401a is pushed up, so that the first vertical groove 401b slides on the outer wall of the first support shaft 402b. The second support shaft 402c slides from the end of the second vertical groove 401c-2 away from the arc groove 401c-1 into the arc groove 401c-1. After the second support shaft 402c enters the arc groove 401c-1, the first support shaft 402b just enters the bottom end of the first vertical groove 401b. At this time, the support mechanism 300 can be rotated by rotating the rotating plate 401a. The second support shaft 402c slides on the inner wall of the arc groove 401c-1. After the support mechanism 300 is rotated, the heat exchange mechanism 100 can be slidably inserted into the installation mechanism 200 for installation.

[0042] After installation, push the heat exchange mechanism 100 to rotate the rotating plate 401a. The second support shaft 402c slides from the inside of the arc groove 401c-1 into the inside of the second vertical groove 401c-2. When the second support shaft 402c just enters the second vertical groove 401c-2, the heat exchange mechanism 100 is in a vertical state. By pulling down the rotating plate 401a, the height of the heat exchange mechanism 100 decreases, allowing the second support shaft 402c to enter the top of the second vertical groove 401c-2, and the first support shaft 402b to enter the top of the first vertical groove 401b. Since the first vertical groove 401b and the second vertical groove 401c-2 are parallel to each other, the rotating plate 401a cannot rotate at this time, thus locking the installation angle. At the same time, due to the decrease in the height of the heat exchange mechanism 100, the water inlet on the heat exchange mechanism 100 can be connected to the high-temperature circulating water of the unit, completing the installation.

[0043] Example 2, refer to Figures 1-5 This is the second embodiment of the present invention. Unlike the previous embodiment, the connecting mechanism 400 further includes a locking member 403 disposed on the rotating plate 401a and a snap-fit ​​member 404 disposed on the connecting frame 402a. In this embodiment, each rotating member 401 is provided with a locking member 403 and a snap-fit ​​member 404. The locking member 403, together with the snap-fit ​​member 404, can lock the angle of the rotating plate 401a after rotation.

[0044] Specifically, the locking member 403 includes an arc-shaped strip 403a disposed on the rotating plate 401a and a slot 403b disposed on the arc-shaped strip 403a. In this embodiment, the arc-shaped strip 403a is fixedly disposed on the surface of the rotating plate 401a, and a plurality of slots 403b are provided on the surface of the arc-shaped strip 403a in an equally spaced manner. The plurality of slots 403b are disposed along the shorter arc-shaped edge of the arc-shaped strip 403a.

[0045] Preferably, the snap-fit ​​component 404 includes a connecting seat 404a disposed on the connecting frame 402a, and a guide sleeve 404b disposed on the connecting seat 404a. A push rod 404c is slidably connected to the inner wall of the guide sleeve 404b, and a push block 404d is disposed at the end of the push rod 404c. A connecting spring 404e is sleeved on the outer wall of the guide sleeve 404b, and a snap-fit ​​block 404f is fixedly disposed on the surface of the push block 404d. In this embodiment, the connecting seat 404a is fixedly disposed on the surface of the connecting frame 402a. A guide sleeve 404b is fixedly installed at the bottom of the connecting seat 404a. The push rod 404c can slide on the inner wall of the guide sleeve 404b. The two ends of the connecting spring 404e are fixedly connected to the connecting seat 404a and the push block 404d respectively. The push block 404d is fixedly located at the end of the push rod 404c away from the connecting seat 404a. A snap-fit ​​block 404f is fixedly provided on the side surface of the push block 404d near the connecting frame 402a. The outer wall size of the snap-fit ​​block 404f matches the inner wall size of the slot 403b.

[0046] Furthermore, the slot 403b is provided with a pressure surface 403c. In this embodiment, the pressure surface 403c can push the locking block 404f when the rotating plate 401a rotates, so that the push rod 404c slides on the inner wall of the guide sleeve 404b, which facilitates the rotation of the rotating plate 401a.

[0047] Preferably, the arc-shaped strip 403a is provided with an outward pushing surface 403d and a spreading surface 403e. In this embodiment, the outward pushing surface 403d is provided on the side of the arc-shaped strip 403a away from the slot 403b, and the spreading surface 403e is provided on the side of the arc-shaped strip 403a away from the support mechanism 300.

[0048] Preferably, the arc-shaped strip 403a is provided with a compression surface 403f; in this embodiment, the compression surface 403f is an arc surface and is provided on the side of the arc-shaped strip 403a near the connecting frame 402a.

[0049] Preferably, the snap-fit ​​connector 404 is inclined.

[0050] It should be noted that the support mechanism 300 includes a fixing strip 301 provided on the mounting mechanism 200, and a connecting hole 302 provided on the fixing strip 301. It also includes a crossbar 303 provided on the fixing strip 301. In this embodiment, the surface of the fixing strip 301 is fixedly connected to the surface of the rotating plate 401a. The surface of the fixing strip 301 near both ends is provided with a plurality of connecting holes 302 distributed at equal intervals. Each support mechanism 300 consists of a crossbar 303 and two fixing strips 301. The two fixing strips 301 are connected and fixed by the crossbar 303. The connecting hole 302 is used to install the mounting mechanism 200.

[0051] The rest of the structure is the same as in Example 1.

[0052] In the initial state, the first support shaft 402b is located at the top of the first vertical groove 401b, the second support shaft 402c is located at the top of the second vertical groove 401c-2, the connecting spring 404e is in a naturally extended state, and the snap-fit ​​block 404f is located directly above the compression surface 403f.

[0053] When disassembling the heat exchange mechanism 100, first disconnect the connection between the water inlet on the heat exchange mechanism 100 and the high-temperature circulating water of the unit. After disconnection, push the heat exchange mechanism 100 upwards to make the first vertical groove 401b slide on the outer wall of the first support shaft 402b, and the second support shaft 402c slides from the end of the second vertical groove 401c-2 away from the arc groove 401c-1 and closer to the arc groove 401c-1. During this process, as the rotating plate 401a is pushed upwards and its height increases, the compression surface 403f will squeeze the clamping block 404f, causing the connecting spring 4 to... 04e compression, since the snap-fit ​​part 404 is set at an angle, after the push rod 404c slides into the guide sleeve 404b, the snap-fit ​​block 404f is displaced in an inclined state. When the first support shaft 402b is at the bottom of the first vertical groove 401b, and the second support shaft 402c is just entering the arc groove 401c-1, the snap-fit ​​block 404f is just aligned with the slot 403b closest to the compression surface 403f. At this time, the snap-fit ​​block 404f is pushed into the slot 403b by the elastic force of the connecting spring 404e, forming a snap-fit.

[0054] When the first support shaft 402b is at the bottom of the first vertical groove 401b, and the second support shaft 402c is just entering the arc groove 401c-1, the support mechanism 300 is rotated. During the rotation, guided by the pressure surface 403c, the locking block 404f can slide along the surface of the pressure surface 403c, applying pressure to the connecting spring 404e. After rotating to the appropriate position, under the gravity of the heat exchange mechanism 100, the rotating plate 401a has a tendency to return to its original rotation. At this time, the locking block 404f and the slot 403b can lock the angle, preventing the support mechanism 300 from becoming vertical under the gravity, which facilitates the installation, disassembly, and cleaning of the heat exchange mechanism 100.

[0055] Continue rotating the support mechanism 300 until the locking block 404f disengages from the arc-shaped strip 403a. At this point, under the action of the connecting spring 404e, the push rod 404c is pushed out from inside the guide sleeve 404b, causing the locking block 404f to extend forward. The connecting spring 404e returns to its natural extended state. Then, rotate the support mechanism 300 in the opposite direction. At this time, the surface of the locking block 404f will abut against the spreading surface 403e. During the reverse rotation of the rotating plate 401a, the spreading surface 403e will push the locking block 404f away, the connecting spring 404e extends, and the locking block 404f slides along the surface of the outer pushing surface 403d until... The second support shaft 402c slides into the second vertical groove 401c-2. At this time, the support mechanism 300 is pushed down, and the arc-shaped bar 403a will continue to abut against the locking block 404f, causing the push rod 404c to slide from the inside of the guide sleeve 404b. The locking block 404f slides at an angle. When the second support shaft 402c slides to the part near the top of the second vertical groove 401c-2, since the locking block 404f is moving at an angle, the locking block 404f and the arc-shaped bar 403a just lose their abutment relationship. The connecting spring 404e will contract and recover, so that the locking block 404f returns to the position directly above the compression surface 403f, returning to the initial state.

[0056] Finally, connect the water inlet on the heat exchange mechanism 100 to the high-temperature circulating water of the unit to complete the installation.

[0057] Example 3, referring to Figures 1-14 This is the third embodiment of the present invention. Unlike the previous embodiment, the heat exchange mechanism 100 includes a microchannel plate heat exchanger body 101 and side frames 102 fixedly disposed on both sides of the microchannel plate heat exchanger body 101. The surface of the side frames 102 is provided with a sliding groove 103. In this embodiment, side frames 102 are fixedly installed on both sides of the microchannel plate heat exchanger body 101, and the front and back sides of each side frame 102 are provided with a sliding groove 103.

[0058] The installation mechanism 200 includes a sliding sleeve 201 slidably disposed on the outer wall of the side frame 102, and a connector 202 fixedly disposed on the outer wall of the sliding sleeve 201. A pushing component 203 is slidably connected to the outer wall of the connector 202. The pushing component 203 is disposed through the sliding sleeve 201. The installation mechanism 200 also includes an adjusting component 204 rotatably disposed on the outer wall of the pushing component 203. In this embodiment, four installation mechanisms 200 are provided, which are located at the four corners of the heat exchange mechanism 100. The sliding sleeve 201 is slidably disposed on the outer wall of the side frame 102 through the sliding groove 103. The connector 202 is used to connect the sliding sleeve 201. The pushing component 203 can slide on the outer wall of the connector 202 and can slide inside the sliding sleeve 201. The adjusting component 204 and the pushing component 203 are rotatably connected.

[0059] The pushing assembly 203 includes a connecting plate 203a slidably disposed on the outer wall of the connector 202, and an abutment 203b fixedly disposed on the connecting plate 203a. It also includes a pressing member 203c slidably disposed on the abutment 203b. In this embodiment, six abutments 203b are fixedly disposed on the side of the connecting plate 203a near the sliding sleeve 201. The six abutments 203b are arranged in an equally spaced array on one side of the connecting plate 203a. The pressing member 203c is slidably disposed inside the sliding sleeve 201 and can slide out or retract inside the sliding sleeve 201. The outer walls of the pressing member 203c and the abutment 203b are slidably connected. It should be noted that when the adjusting member 204 rotates, it can push or pull the abutment 203b to slide. The sliding of the abutment 203b can push the pressing member 203c to extend or retract from inside the sliding sleeve 201.

[0060] Specifically, the sliding socket 201 includes a socket buckle 201a slidably disposed on the outer wall of the side frame 102, a connecting groove 201b disposed on the socket buckle 201a, and a receiving groove 201c disposed on the connecting groove 201b. In this embodiment, the socket buckle 201a can slide on the outer wall of the side frame 102 through the sliding groove 103. The socket buckle 201a has a connecting groove 201b inside, which passes through both ends of the socket buckle 201a. The connecting groove 201b and the abutment member 203b are arranged in a one-to-one correspondence. The receiving groove 201c and the connecting groove 201b are in a connected state and are perpendicular to each other. The inner wall of the receiving groove 201c and the outer wall of the pressing member 203c are slidably connected.

[0061] Preferably, the abutment member 203b includes a slide rod 203b-1 slidably disposed on the connecting groove 201b, and a pressing surface 203b-2 disposed at the end of the slide rod 203b-1. In this embodiment, the slide rod 203b-1 is fixedly connected to one side of the connecting plate 203a. The end of the slide rod 203b-1 away from the connecting plate 203a is provided with a pressing surface 203b-2. The pressing surface 203b-2 is inclined. By setting the pressing surface 203b-2, when the slide rod 203b-1 slides close to the pressing member 203c, it can push the pressing member 203c to extend out from the inside of the sleeve buckle 201a, thereby pressing the inner surface of the slide groove 103 on the side frame 102 to form a clamping and positioning.

[0062] Preferably, the extrusion component 203c includes a sliding column 203c-1 slidably disposed on the receiving groove 201c, and an extrusion ball 203c-2 fixedly disposed on the sliding column 203c-1. In this embodiment, the sliding column 203c-1 can slide inside the receiving groove 201c, and the sliding column 203c-1 and the receiving groove 201c are arranged in a one-to-one correspondence. The extrusion ball 203c-2 is disposed at one end opposite to each pair of sliding columns 203c-1. The extrusion ball 203c-2 can extend or retract from the inside of the sleeve buckle 201a after the sliding column 203c-1 slides. By having two opposing extrusion balls 203c-2 extend from the inside of the sleeve buckle 201a at the same time, the surface of the sliding groove 103 is clamped, and the side frame 102 can be clamped and positioned.

[0063] Preferably, the heat exchange mechanism 100 further includes positioning holes 104 provided on the inner surface of the slide 103. In this embodiment, a plurality of positioning holes 104 are uniformly provided on the surface of the slide 103. By setting the positioning holes 104, after the extrusion ball 203c-2 extends out from the inside of the sleeve buckle 201a, it can enter the interior of the positioning hole 104, thereby improving the fixing effect on the side frame 102.

[0064] Furthermore, the extrusion member 203c also includes an abutment surface 203c-5 disposed on the slide post 203c-1. In this embodiment, the abutment surface 203c-5 is inclined, and the abutment surface 203c-5 and the extrusion surface 203b-2 are parallel to each other. When the slide post 203b-1 slides inside the sleeve buckle 201a, the extrusion surface 203b-2 pushes the abutment surface 203c-5, which enables the slide post 203c-1 to slide, thereby causing the extrusion ball 203c-2 to extend out from inside the sleeve buckle 201a.

[0065] In use, the installation mechanism 200 is used to connect with the fixing bar 301. The heat exchange mechanism 100 is installed through the installation mechanism 200. During the operation of the unit, the intake air temperature is increased by the operation of the microchannel plate heat exchanger body 101. The water inlet of the microchannel plate heat exchanger body 101 is connected to the high-temperature circulating water of the unit. The air in the gas turbine intake passage is preheated through the microchannel plate heat exchanger body 101.

[0066] During installation, first insert the side frame 102 into the sliding sleeve 201, and form a sleeve relationship between the sliding groove 103 and the sleeve buckle 201a. After adjusting the microchannel plate heat exchanger body 101 to a suitable position, rotate the adjusting component 204 to make the contact component 203b slide into the sleeve buckle 201a. When the sliding rod 203b-1 slides, it pushes the contact surface 203c-5 through the extrusion surface 203b-2, so that the sliding column 203c-1 slides inside the receiving groove 201c. As the sliding distance of the sliding rod 203b-1 increases, the sliding distance of the sliding column 203c-1 gradually increases, and then the extrusion ball 203c-2 slides out from the inside of the sleeve buckle 201a and enters the inside of the positioning hole 104 to form a snap-fit ​​relationship. At this time, the connection and fixation of the sliding sleeve 201 and the side frame 102 can be completed by the snap-fit ​​of the positioning hole 104 and the extrusion ball 203c-2.

[0067] During disassembly, simply rotate the adjusting member 204 in the reverse direction to pull the contact member 203b out from inside the sleeve buckle 201a. Since the extrusion surface 203b-2 and the contact surface 203c-5 lose their contact relationship, the sliding column 203c-1 can slide inside the receiving groove 201c. At this time, the microchannel plate heat exchanger body 101 can be slid and pulled out. Under the action of the spherical surface of the extrusion ball 203c-2, it can be disengaged from the positioning hole 104 and the extrusion ball 203c-2 can be retracted into the sleeve buckle 201a. The microchannel plate heat exchanger body 101 can be removed by pulling out, thus achieving quick disassembly of the heat exchange mechanism 100.

[0068] The sliding sleeve 201 further includes a limiting groove 201d on the sleeve buckle 201a and a receiving groove 201e on the connecting groove 201b; the abutting member 203b further includes a through block 203b-3 fixedly disposed on the end of the slide rod 203b-1 and a fastening block 203b-5 fixedly disposed on the through block 203b-3; the pressing member 203c further includes a limiting slider 203c-3 fixedly disposed on the slide column 203c-1 and a through groove 203c-4 disposed on the limiting slider 203c-3 and the slide column 203c-1. In this embodiment, the limiting groove 201d is a semi-cylindrical groove, and the outer wall size of the limiting slider 203c-3 and the inner wall size of the limiting groove 201d are matched with each other. The sliding block 203c-3 is slidably connected to the outer wall of the limiting slider 203c-3. The limiting slider 203c-3, in conjunction with the limiting groove 201d, can restrict the rotation of the sliding column 203c-1, thereby keeping the extrusion surface 203b-2 and the contact surface 203c-5 parallel to each other, which facilitates the sliding rod 203b-1 to push the sliding column 203c-1. The receiving groove 201e provides space for the sliding block 203b-3 to slide. The sliding block 203b-3 slides the column 203c-1 through the through groove 203c-4. The fastening block 203b-5 is fixed on the end of the sliding block 203b-3 away from the sliding rod 203b-1. The fastening block 203b-5 can prevent the sliding block 203b-3 from sliding excessively and from disengaging from the through groove 203c-4.

[0069] Specifically, the abutting member 203b also includes a pushing surface 203b-4 provided on the through block 203b-3. In this embodiment, the pushing surface 203b-4 is provided on the side surface of the through block 203b-3 away from the extrusion surface 203b-2. By providing the pushing surface 203b-4, when the slide rod 203b-1 is pulled out from inside the socket 201a, the pushing surface 203b-4 pushes the edge of the through groove 203c-4, causing the slide rod 203c-1 to slide on the inner wall of the receiving groove 201c, thereby causing the extrusion ball 203c-2 to be retracted into the socket 201a.

[0070] When disassembling the heat exchange mechanism 100, by rotating the adjusting component 204, the contact component 203b is pulled out from the inside of the sleeve buckle 201a. When the slide rod 203b-1 is pulled out, the extrusion surface 203b-2 and the contact surface 203c-5 lose their contact relationship. Furthermore, the through block 203b-3 slides on the inner wall of the through groove 203c-4. The pushing surface 203b-4 on the through block 203b-3 and the edge of the through groove 203c-4 will abut. The pushing surface 203b-4 pushes the edge of the through groove 203c-4, causing the slide rod 203c-1 to slide on the inner wall of the receiving groove 201c. This causes the extrusion ball 203c-2 to be retracted into the sleeve buckle 201a, thus separating it from the positioning hole 104. The microchannel plate heat exchanger body 101 is then removed by pulling, achieving rapid disassembly of the heat exchange mechanism 100.

[0071] The pushing assembly 203 also includes a limiting ring 203d fixedly disposed on the connecting plate 203a; the adjusting member 204 includes a rotating sleeve 204a rotatably disposed on the outer wall of the limiting ring 203d, and a torsion block 204b fixedly disposed on the outer wall of the rotating sleeve 204a, and a pushing groove 204c disposed on the rotating sleeve 204a; the connecting member 202 includes a connecting post 202a fixedly disposed on the outer wall of the socket buckle 201a, and a guide block 202b fixedly disposed on the outer wall of the connecting post 202a. In this embodiment, the outer wall of the torsion block 204b is hexagonal and can be twisted and rotated with a wrench. The pushing groove 204c is opened on the outer surface of the rotating sleeve 204a. The outer wall of the guide block 202b and the inner wall of the pushing groove 204c are slidably connected. The connecting post 202a passes through the limiting ring 203d, and the limiting ring 203d can slide on the outer wall of the connecting post 202a.

[0072] Specifically, the pushing groove 204c includes a straight groove 204c-1 provided on the rotating sleeve 204a, and an inclined groove 204c-2 and a retention groove 204c-3 provided on the rotating sleeve 204a. In this embodiment, the straight groove 204c-1, the inclined groove 204c-2 and the retention groove 204c-3 are connected in sequence.

[0073] Furthermore, the pushing groove 204c also includes a V-shaped groove 204c-4 provided on the retention groove 204c-3. In this embodiment, the V-shaped groove 204c-4 is provided on the side surface of the retention groove 204c-3 away from the connecting plate 203a. The guide block 202b can be positioned by the design of the V-shaped groove 204c-4.

[0074] Preferably, the connector 202 further includes a contact plate 202c disposed on the connecting post 202a and a threaded groove 202d disposed on the connecting post 202a; the mounting mechanism 200 further includes a thrust spring 205 disposed at the end of the contact plate 202c and a mounting bolt 206 disposed in the threaded groove 202d. In this embodiment, one end of the thrust spring 205 is attached to one end of the contact plate 202c, and the other end of the thrust spring 205 is attached to the surface of the torsion block 204b. The thrust spring 205 is sleeved on the outer wall of the rotating sleeve 204a. The elastic force of the thrust spring 205 can make the rotating sleeve 204a have a tendency to move away from the contact plate 202c. The threaded groove 202d is opened at the end of the connecting post 202a away from the sleeve buckle 201a. Through the threaded connection of the mounting bolt 206 and the threaded groove 202d, and in conjunction with the contact plate 202c, the mounting mechanism 200 can be mounted on the fixing strip 301.

[0075] Furthermore, the connector 202 also includes an outer sleeve 202e disposed on the contact plate 202c; the adjusting member 204 also includes an inner sleeve 204d disposed on the torsion block 204b; the outer wall of the inner sleeve 204d and the inner wall of the outer sleeve 202e are slidably connected. In this embodiment, the outer sleeve 202e is fixedly disposed at one end of the contact plate 202c near the torsion block 204b, and the inner sleeve 204d is fixedly disposed at one end of the torsion block 204b near the contact plate 202c. Through the mutual cooperation of the inner sleeve 204d and the outer sleeve 202e, the sliding of the rotating sleeve 204a can be limited, and the internal thrust spring 205 can be protected.

[0076] The rest of the structure is the same as in Example 2.

[0077] When the guide block 202b is inside the straight groove 204c-1, the extrusion surface 203b-2 and the contact surface 203c-5 are in contact, and the extrusion ball 203c-2 is protruding from the socket 201a. When disassembling the side frame 102 and the sliding socket 201, the torsion block 204b is rotated, and the guide block 202b slides from inside the straight groove 204c-1 into the inclined groove 204c-2. Guided by the inclined groove 204c-2, the thrust spring 205 is compressed, and the rotating sleeve 204a and the connecting plate 203a slide on the outer wall of the connecting column 202a. The slide rod 203b-1 will then... When the socket buckle 201a is pulled out, during the process, the pressing ball 203c-2 on the pressing member 203c retracts into the socket buckle 201a through the contact member 203b. Finally, the guide block 202b slides into the retention groove 204c-3. At this time, the elastic force of the thrust spring 205 can push the rotating sleeve 204a to slide on the outer wall of the connecting column 202a, thereby allowing the guide block 202b to enter the V-groove 204c-4. Under the action of the elastic force of the thrust spring 205, the guide block 202b and the V-groove 204c-4 form a snap-fit. At this time, it can be disassembled by pulling out the heat exchange mechanism 100.

[0078] During installation, first insert the side frame 102 into the socket 201a. After adjusting the microchannel plate heat exchanger body 101 to a suitable position, rotate the torsion block 204b to allow the guide block 202b to enter the straight groove 204c-1. During this process, the extrusion surface 203b-2 pushes the contact surface 203c-5, causing the extrusion ball 203c-2 to extend from the socket 201a. The extrusion ball 203c-2 and the positioning hole 104 are engaged to fix the side frame 102. Finally, the spring force of the thrust spring 205 pushes the torsion block 204b to keep the rotating sleeve 204a away from the contact plate 202c, thereby keeping the guide block 202b inside the straight groove 204c-1 and completing the installation and fixation of the heat exchange mechanism 100.
