Description

A modular assembled heat exchange device Technical Field

[0001] This utility model relates to the field of heat exchange technology, specifically to a modular assembled heat exchange device. Background Technology

[0002] In the field of heat exchanger technology, plate heat exchanger structures with multiple heat exchange plates assembled side by side have become the mainstream design direction for improving heat exchange efficiency. Such devices typically utilize flow channels of a specific shape on the surface of the heat exchange plates. Existing heat exchange plates usually employ straight, zigzag, or simple arc-shaped flow channels, whose core function is to guide fluid flow along a predetermined path to achieve heat exchange. However, the insufficient matching between the length of the flow channels and the fluid flow velocity results in a short residence time of the fluid between the heat exchange plates, failing to fully complete the heat exchange process. This is especially true when the medium flow velocity is high, where the heat transfer efficiency is significantly reduced. Summary of the Invention

[0003] The main purpose of this invention is to provide a modular assembled heat exchange device to solve the problem that the existing technology has insufficient matching between the length of the diversion channel and the fluid flow rate, resulting in a short residence time of the fluid between the heat exchange plates and the inability to fully complete the heat exchange.

[0004] To achieve the above objectives, this utility model provides a modular assembled heat exchange device, including a base frame, the base frame including a fixed plate and a movable plate that moves along the length of the base frame, the movable plate being fixed parallel to one side of the fixed plate by fasteners, and multiple modules being arranged side by side between the movable plate and the fixed plate.

[0005] The module includes two rectangular heat exchange plates arranged side by side and upside down.

[0006] Flow holes are opened through all four corners of the heat exchange plate;

[0007] The heat exchange plate has an annular groove, two circular grooves, and a serpentine groove along its length on one side wall;

[0008] The two flow holes and the serpentine groove on the right side are all located inside the annular groove, and are connected to both ends of the serpentine groove through multiple guide grooves;

[0009] The two circular grooves correspond one-to-one with the two flow holes on the left side. The flow holes on the left side are set inside the circular grooves and are connected to the annular grooves through multiple arc-shaped grooves.

[0010] The sealing strip is filled with annular grooves, two circular grooves, and multiple arc grooves.

[0011] Preferably, the flow holes on the left side of the multiple heat exchange plates form two heat channels;

[0012] One end of a hot channel is connected to a hot liquid inlet pipe, and the other end of the hot liquid inlet pipe and the hot liquid outlet pipe are connected to a hot liquid outlet pipe. The ends of the hot liquid inlet pipe and the hot liquid outlet pipe that are away from the hot channels pass through and are fixed on a fixed plate.

[0013] The flow holes on the right side of multiple heat exchange plates form two cold channels;

[0014] One end of a cold aisle is connected to a cold inlet pipe, and the other end of the cold inlet and cold outlet pipes is connected to a cold outlet pipe. The ends of the cold inlet and cold outlet pipes away from the cold aisles pass through and are fixed to a fixed plate.

[0015] Preferably, the base frame also includes two sliding beams and a support column, with one end of each sliding beam fixedly connected to a fixed plate and the other end of each beam fixedly connected to the support column.

[0016] The top and bottom sidewalls of the moving plate and heat exchange plate are all provided with slots, and the two slots correspond one-to-one with the two sliding beams, and are slidably set on the sliding beams.

[0017] Preferably, a support is fixed to the top of the sliding plate, and a roller is rotatably mounted on the support. The roller is located directly above the upper groove and rests on the sliding beam.

[0018] Preferably, mounting plates are fixed to the bottom ends of the support column and the fixed plate, and multiple horizontally arranged mounting plates are located at the same height and each has multiple mounting holes.

[0019] Preferably, the fastener includes a plurality of first bolts;

[0020] Both the sliding plate and the fixed plate are rectangular plates, and multiple receiving holes are opened through the four sides of both.

[0021] One end of each first bolt passes through the receiving hole of the fixed plate and the receiving hole of the moving plate in sequence and is screwed to the first nut.

[0022] Preferably, the fastener also includes two second bolts;

[0023] The upper and lower middle sidewalls of both the moving plate and the fixed plate have a first through hole.

[0024] A second through hole is provided through the upper and lower middle sidewalls of the heat exchange plate;

[0026] Preferably, circular blind grooves are coaxially formed on the outer walls of the two second through holes of the heat exchange plate, and each circular blind groove is filled with a sealing ring.

[0027] The above plan has the following beneficial effects:

[0028] Two sets of heat exchange plates are interlocked in a mirror-image configuration. The flow holes at the four corners of the heat exchange plates form a sealed connection with adjacent modules via sealing strips. The upper and lower flow holes on the left automatically form a hot fluid channel, while the upper and lower flow holes on the right form a cold fluid channel. Multiple modules are clamped and fixed by the base frame's fixed and movable plates. The movable plates adjust their spacing along the length of the base frame to accommodate the side-by-side assembly of different numbers of modules. Hot fluid flows in from the upper left flow hole, enters the serpentine channel through the guide groove of one heat exchange plate, and flows into the inlet end of the serpentine channel. Cold fluid enters from the lower right flow hole, passes through another heat exchange plate, and forms a flow path opposite to that of the cold fluid. The hot and cold fluids flow in completely opposite directions within the module, with the hot fluid flowing along a meandering path within the serpentine channel, achieving efficient heat exchange. The extended residence time of the fluid within the module ensures sufficient heat exchange even under high flow rate conditions. Attached Figure Description

Therefore, the present invention is not limited to the specific embodiments disclosed below. Embodiments

[0043] As shown in Figures 1-4, this embodiment provides a modular assembled heat exchange device, including a base frame 1. The base frame 1 includes a fixed plate 11 and a movable plate 12 that moves along the length of the base frame 1. As shown in Figures 1 and 2, the movable plate 12 is fixed parallel to one side of the fixed plate 11 by fasteners 2. Multiple modules 3 are arranged side by side between the movable plate 12 and the fixed plate 11. The base frame 1 also includes two sliding beams 13 and support columns 14. One end of the two sliding beams 13 is fixedly connected to the fixed plate 11, and the other end of the two sliding beams 13 is fixedly connected to the support column 14. The top, bottom, and side walls of the movable plate 12 and the heat exchange plate 31 are all provided with through slots 10. The two slots 10 correspond one-to-one with the two sliding beams 13 and are slidably disposed on the sliding beams 13. It should be noted that the groove is embedded in the sliding beam, and a bracket 15 is fixed to the top of the moving plate 12. A roller 16 is rotatably mounted on the bracket 15. The roller 16 is located directly above the groove 10 and rests on the sliding beam 13. Mounting plates 17 are fixed to the bottom of the support column 14 and the bottom of the fixed plate 11. Multiple horizontally arranged mounting plates 17 are at the same height, and each mounting plate 17 has multiple mounting holes 170. The fastener 2 includes multiple first bolts 21. Both the moving plate 12 and the fixed plate 11 are rectangular plates, and multiple receiving holes 100 are opened through the four edges of both. One end of each first bolt 21 passes through the receiving hole 100 of the fixed plate 11 and the receiving hole 100 of the moving plate 12 and is screwed with a first nut 22. The fastener 2 also includes two second bolts 23. First through holes (not shown) are opened through the upper and lower side walls of the moving plate 12 and the fixed plate 11. As shown in Figure 4, second through holes 30 are provided through the upper and lower middle sidewalls of the heat exchange plate 31. One end of each second bolt 23 passes through the first through hole, the second through hole 30, and the receiving hole 100 of the moving plate 12 in sequence, and is screwed with a second nut 24. The addition of two second bolts 23 and two second nuts 24 increases the sealing between multiple modules 3 and prevents leakage. Circular blind grooves 37 are coaxially provided on the outer walls of the two second through holes 30 of each heat exchange plate 31, and each circular blind groove 37 is filled with a sealing ring 7. The sealing ring 7 increases the sealing between the heat exchange plates 31. As shown in Figure 4, the module 3 includes two rectangular heat exchange plates 31, which are arranged side by side and inverted. Flow holes 310 are provided through the four corners of each heat exchange plate 31. An annular groove 32, two circular grooves 33, and a serpentine groove 34 along the length of each heat exchange plate 31 are provided on one sidewall. The two flow holes 310 and the serpentine groove 34 on the right side are all located within the annular groove 32. This can also be understood as the two flow holes 310 and the serpentine groove 34 being set within the area enclosed by the annular groove, and the two flow holes 310 and the serpentine groove 34 are connected to both ends of the serpentine groove 34 via multiple guide grooves 35. The two circular grooves 33 correspond one-to-one with the two flow holes 310 on the left side. The flow holes 310 on the left side are set within the circular grooves 33 and are connected to the annular groove 32 via multiple arc-shaped grooves 36. The annular groove 32, the two circular grooves 33, and the multiple arc-shaped grooves 36 are filled with sealing strips 4.

[0044] Two sets of heat exchange plates 31 are interlocked in a mirror-image manner. The flow holes 310 at the four corners of the heat exchange plates 31 form a sealed connection with the adjacent modules 3 through the sealing strip 4. The upper and lower flow holes 310 on the left automatically form a hot fluid channel, and the upper and lower flow holes 310 on the right form a cold fluid channel. Multiple modules 3 are clamped and fixed by the fixed plate 11 and the moving plate 12 of the base frame 1. The spacing of the moving plate 12 is adjusted along the length of the base frame 1 to adapt to the side-by-side assembly requirements of different numbers of modules 3. The hot fluid flows in from the upper left flow hole 310 and is injected into the liquid inlet end of the serpentine groove 34 through the guide groove 35 of one heat exchange plate 31 of the module 3. The cold fluid enters from the lower right flow hole 310 and forms a flow path opposite to that of the cold fluid through another heat exchange plate 31 of the module 3. The hot and cold fluids flow in completely opposite directions within module 3, while the hot fluid flows in a meandering path within the serpentine channel 34, achieving efficient heat exchange. The extended residence time of the fluid within module 3 ensures that sufficient heat exchange can still be completed under high flow rate conditions.

[0045] As shown in Figure 3, the flow holes 310 on the left side of the multiple heat exchange plates 31 form two hot channels 5. One end of one hot channel 5 is connected to the hot liquid inlet pipe 51, and the other hot channel 5 is connected to the hot liquid outlet pipe 52. The ends of the hot liquid inlet pipe 51 and the hot liquid outlet pipe 52 away from the hot channel 5 pass through and are fixed to the solid plate 11. The flow holes 310 on the right side of the multiple heat exchange plates 31 form two cold channels 6. One end of one cold channel 6 is connected to the cold liquid inlet pipe 61, and the other cold channel 6 is connected to the cold liquid outlet pipe 62. The ends of the cold liquid inlet pipe 61 and the cold liquid outlet pipe 62 away from the cold channel 6 pass through and are fixed to the solid plate 11.

[0046] Hot fluid (such as hot water) flows into the hot channel 5 on the left side of the base frame 1 from the hot inlet pipe 51. The hot channel 5 is composed of multiple heat exchange plates 31 with two parallel flow holes 310 on the left side. The hot fluid enters the annular groove 32 of the first module 3 through the upper left flow hole 310, and another part enters the annular groove 32 of the adjacent module 3 through the lower left flow hole 310, achieving uniform flow distribution. Cold fluid (such as cold water) flows into the cold channel 6 on the right side of the base frame 1 from the cold inlet pipe 61. The cold channel 6 is composed of multiple heat exchange plates 31 with two parallel flow holes 310 on the right side. The cold fluid enters the annular groove 32 of the first module 3 through the lower right flow hole 310, and another part enters the annular groove 32 of the adjacent module 3 through the upper right flow hole 310, forming an initial distribution in the opposite direction to that of the hot fluid. The two heat exchange plates 31 of the module 3 complete the heat exchange process.

[0047] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
