Description

Technical Field

[0001] This application relates to the field of marine heat exchange equipment, and more particularly to a marine heat exchanger. Background Technology

[0002] Marine heat exchangers are key equipment in marine power systems, air conditioning systems, and thermal energy management. They are mainly used to cool media such as lubricating oil, engine circulating water, and air conditioning refrigerant.

[0003] Freshwater resources are scarce when ships are at sea, so seawater is typically used for heat exchange. However, seawater contains a large amount of salt and other chemicals, which can easily form scale inside the pipes after heat exchange, clogging the pipes, affecting flow rate, and reducing heat exchange efficiency. Furthermore, in existing heat exchangers, the heat exchange pipes are bent and distributed within the heat sink fins, making internal cleaning difficult. Summary of the Invention

[0004] To facilitate the cleaning of scale inside heat exchange pipes, this application provides a heat exchanger for ships.

[0005] The technical solution for a marine heat exchanger provided in this application is as follows:

[0006] A heat exchanger for ships includes two end plates and a plurality of heat dissipation plates stacked between the two end plates. A plurality of heat exchange tubes arranged in a bent pattern are passed through the heat dissipation plates. The heat exchange tubes are divided into left half tubes and right half tubes, which are spliced ​​together to form a heat exchange tube. The heat dissipation plates are composed of a plurality of plate bodies, the plate bodies being divided at the positions where the heat exchange tubes are passed through. The plate bodies of the plurality of heat dissipation plates are arranged in an array between the two end plates. The plate bodies of the plurality of heat dissipation plates in the same column in the thickness direction of the end plates are fixed together by connecting blocks.

[0007] By adopting the above technical solution, the split-type heat exchange tubes facilitate opening, allowing for easy internal cleaning and descaling of the bent heat exchange tubes. This facilitates the removal of scale buildup within the heat exchange pipes. The split-type heat dissipation plates facilitate the installation and disassembly of the heat exchange tubes, enabling cleaning and descaling of the tubes. However, the large number of heat dissipation plates results in numerous plates after splitting, making disassembly and assembly somewhat inconvenient. The connecting blocks allow for the connection and fixation of plates stacked in the same row between two end plates, facilitating the disassembly and assembly of the plates and improving the efficiency of plate assembly and disassembly.

[0008] Optionally, a disassembly and assembly mechanism is provided between the boards. The disassembly and assembly mechanism includes a disassembly and assembly slot, a disassembly and assembly insert, a disassembly and assembly groove, and a disassembly and assembly block. The disassembly and assembly slot is opened at one end of the width direction of the board, and the disassembly and assembly insert is fixed at the other end of the width direction of the board. When the two boards are spliced, the disassembly and assembly insert on one board is inserted into the disassembly and assembly slot of the other board. The disassembly and assembly groove is opened on the side wall of the disassembly and assembly slot, and the disassembly and assembly block is slidably disposed on the side wall of the disassembly and assembly insert. The disassembly and assembly block is inserted into the disassembly and assembly groove or stored in the disassembly and assembly insert by sliding.

[0009] Optionally, a driving mechanism is provided inside the plate. The driving mechanism includes a driving rod, a driving block, and a driving spring. The driving rod is slidably disposed inside the plate. The driving block is fixed on the driving rod and is a wedge-shaped block. The wedge-shaped surface of the driving block abuts against the disassembly and assembly block. The driving spring is installed inside the plate. The elastic force of the driving spring causes one end of the driving rod to be flush with the bottom of the disassembly and assembly slot in its normal state, and the other end to extend out of the disassembly and assembly block. The elastic force of the driving spring causes the driving block to drive the disassembly and assembly block to extend out of the disassembly and assembly block.

[0010] Optionally, both ends of the two end plates are provided with a fixing mechanism. The fixing mechanism includes a fixing groove, a fixing bolt, and a fixing nut. The fixing groove is opened at one end of the end plate in the width direction, the fixing bolt is placed in the fixing groove, and the fixing nut is threaded onto the fixing bolt.

[0011] Optionally, a reinforcing block is inserted into one end of the heat sink with a disassembly slot. The reinforcing block has bolt holes, and a fixing bolt installed on the side of the heat sink with the disassembly slot passes through the bolt holes.

[0012] Optionally, the fixing bolt installed on one side of the heat sink plate is fixed to the disassembly and assembly block, which abuts against the disassembly and assembly block and drives the drive rod to slide and be housed in the disassembly and assembly block. A drive wedge is fixed on the drive rod. When the drive rod is housed in the disassembly and assembly block, the drive wedge drives the disassembly and assembly block to be inserted into the disassembly and assembly slot.

[0013] Optionally, a reinforcing clip is slidably disposed inside the reinforcing block. When the drive rod extends into the disassembly slot, it is inserted into the reinforcing block, driving the reinforcing clip to slide into the disassembly slot.

[0014] Optionally, both ends of several of the heat exchange tubes extend through the end plate along their length, and both ends of the heat exchange tubes are connected to the main pipe, with an interface fixedly provided on the main pipe.

[0015] Optionally, a retaining ring can be detachably installed on the end plate to fix the main pipe to the end plate.

[0016] Optionally, a support frame is rotatably mounted on the end plate.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. The split-type heat exchange tubes facilitate opening, allowing for easy internal cleaning and descaling of the bent heat exchange tubes. This facilitates the removal of scale buildup within the heat exchange pipes. The split-type heat dissipation plates facilitate the installation and disassembly of the heat exchange tubes, enabling cleaning and descaling of the tubes. However, the large number of heat dissipation plates results in numerous plates after splitting, making disassembly and assembly somewhat inconvenient. The connecting blocks allow for the connection and fixation of plates stacked in the same row between two end plates, facilitating the disassembly and assembly of the plates and improving the efficiency of plate disassembly and assembly.

[0019] 2. The adjacent plates can be connected and aligned by the cooperation of the disassembly and assembly blocks and the disassembly and assembly slots, and the adjacent plates can be fixed by the cooperation of the disassembly and assembly clips and the disassembly and assembly slots.

[0020] 3. When two boards are spliced ​​together, the inner wall of the disassembly slot on one board abuts against the chamfer on the disassembly clip, driving the disassembly clip to slide and be stored in the disassembly insert. Then the disassembly insert is inserted into the disassembly slot. When the disassembly insert is fully inserted into the disassembly slot, the disassembly clip slides into the disassembly slot under the drive of the drive mechanism. When it is necessary to disassemble the board, the drive block is disengaged from the disassembly clip by driving the drive rod to slide. The disassembly clip is stored in the disassembly insert under the action of the return spring. At this time, the disassembly insert can be taken out from the disassembly slot.

[0021] 4. The spacing between the two end plates is adjusted and fixed by the fixing mechanism, so that the two end plates clamp the heat sink more firmly. The reinforcing block is inserted into the disassembly slot and fixed with the fixing bolts to improve the overall structural strength of the end plate and the heat sink, and reduce the probability of the heat sink sliding in the end plate. The reinforcing block slides and is locked in the disassembly slot to reinforce the reinforcing block, reducing the probability of the reinforcing block detaching from the plate, thereby improving the strength of the reinforcing block installation structure.

[0022] 5. When the drive rod is retracted into the disassembly and assembly block, the drive wedge drives the disassembly and assembly block to insert into the disassembly and assembly slot. After the heat sink is installed in the plate body, the drive wedge, in conjunction with the fixing bolt, can drive the disassembly and assembly block to be fixed in the disassembly and assembly slot while reducing the probability of the disassembly and assembly block being dislodged from the disassembly and assembly slot due to external force.

[0023] 6. The interface connects to equipment on the ship that requires heat exchange or to pumping equipment. The main pipe connects heat exchange tubes with the same function, which facilitates the control of heat exchange tubes with the same function. At the same time, the connection between the main pipe and the heat exchange tubes can reduce the probability of the left and right halves of the pipes becoming detached.

[0024] 7. The support frame provides support and reduces the probability of the heat exchanger tipping over. The height of the support frame can be adjusted by sliding the sliding block to adjust the support center of gravity according to actual needs, thereby improving the support effect of the support frame. When the sliding block is at the bottom of the vertical groove, the support frame rotates to fit the ground. Placing counterweights on the support frame can reduce the probability of the heat exchanger slipping under force. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-6 The present application will be further described with reference to specific embodiments:

[0033] First, it should be noted that in the description of this application, the use of directional terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for descriptive purposes and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the use of numerical quantifiers such as "first," "second," and "third" is for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, in this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, interference fits, transition fits, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium. Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] This application discloses a heat exchanger for ships, referring to... Figure 1 , Figure 2 , Figure 3 and Figure 4 The system includes two rectangular end plates 1 and several heat exchange plates 2 stacked between the two end plates 1. Several heat exchange tubes 3 are arranged in a bent pattern on the heat exchange plates 2. The heat exchange tubes 3 are divided into left half tubes 31 and right half tubes 32. The left half tubes 31 and right half tubes 32 are spliced ​​together to form the heat exchange tube 3. A rubber sealing strip 4 is provided between the left half tubes 31 and right half tubes 32. In this embodiment, the rubber sealing strip 4 is made of high-temperature resistant modified rubber. Half of the rubber sealing strip 4 is embedded in the left half tube 31 and the other half is embedded in the right half tube 32. The heat exchange plates 2 are composed of several plates 201. The plate 201 is divided at the position where the heat exchange tubes 3 are inserted. The plates 201 of the several heat exchange plates 2 are arranged in an array between the two end plates 1. The plates 201 on the several heat exchange plates 2 are in the same column as the thickness direction of the end plates 1. The plates 1 are fixed to each other by connecting blocks 5. In this embodiment, the two ends of the connecting blocks 5 are fixed to the plate 201 by welding. The split heat exchange tube 3 facilitates the opening of the heat exchange tube 3. Opening the heat exchange tube 3 facilitates the internal cleaning and descaling of the bent heat exchange tube 3, thereby facilitating the cleaning of scale inside the heat exchange tube 3. The split heat dissipation plate 2 facilitates the installation and disassembly of the heat exchange tube 3, thereby cooperating with the split heat exchange tube 3 to clean and descal the inside of the heat exchange tube 3. Since there are many heat dissipation plates 2, there are many plates 201 after splitting, which is inconvenient to disassemble and assemble. The setting of the connecting blocks 5 can connect and fix the plates 201 stacked in the same column between the two end plates 1, thereby facilitating the disassembly and assembly of the plates 201 and improving the efficiency of disassembly and assembly of the plates 201.

[0035] Reference Figure 1 , Figure 4 and Figure 5 A disassembly and assembly mechanism 6 is provided between the plates 201. In this embodiment, three sets of disassembly and assembly mechanisms 6 are evenly arranged along the length of the plates 201. The disassembly and assembly mechanism 6 includes a disassembly and assembly slot 61, a disassembly and assembly insert 62, a disassembly and assembly groove 63, and a disassembly and assembly block 64. The disassembly and assembly slot 61 is opened at one end of the width direction of the plate 201, and the disassembly and assembly insert 62 is fixed at the other end of the width direction of the plate 201. When two plates 201 are spliced, the disassembly and assembly insert 62 on one plate 201 is inserted into the other plate 201. Within the disassembly and assembly slot 61 of the plate 201, a disassembly and assembly groove 63 is formed on the side wall of the disassembly and assembly slot 61, and a disassembly and assembly block 64 is slidably disposed on the side wall of the disassembly and assembly insert 62. The disassembly and assembly block 64 is inserted into the disassembly and assembly groove 63 or stored in the disassembly and assembly insert 62 by sliding. The cooperation between the disassembly and assembly insert 62 and the disassembly and assembly slot 61 enables adjacent plates 201 to be connected and aligned, and the cooperation between the disassembly and assembly block 64 and the disassembly and assembly groove 63 achieves the fixation between adjacent plates 201.

[0036] Reference Figure 1 , Figure 4 and Figure 5A drive mechanism 7 is provided inside the plate 201. The drive mechanism 7 includes a drive rod 71, a drive block 72, and a drive spring 73. The drive rod 71 is slidably disposed inside the plate 201. The drive block 72 is fixed on the drive rod 71. The drive block 72 is a wedge-shaped block. The wedge-shaped surface of the drive block 72 abuts against the disassembly and assembly latch 64. The drive spring 73 is installed inside the plate 201. The elastic force of the drive spring 73 makes the lower end of the drive rod 71 flush with the bottom of the disassembly and assembly slot 61 in its normal state. The other end extends out as a disassembly / removal insert 62. The elastic force of the drive spring 73 causes the drive block 72 to drive the disassembly / removal latch 64 to extend out of the disassembly / removal insert 62. The disassembly / removal latch 64 has a chamfer 8 at the end facing away from the plate 201. A return spring 9 is provided between the disassembly / removal latch 64 and the disassembly / removal insert 62. The return spring 9 drives the disassembly / removal latch 64 to be retracted into the disassembly / removal insert 62. In this embodiment, the elastic force of the return spring 9 on the disassembly / removal insert 62 is less than the elastic force of the drive spring 73, thereby ensuring... The spring 9 drives the disassembly / removal latch 64 to extend from the disassembly / removal insert 62. When the drive block 72 moves away from the disassembly / removal latch 64, the return spring 9 drives the disassembly / removal latch 64 to retract into the disassembly / removal insert 62. Normally, the disassembly / removal latch 64 extends from the disassembly / removal insert 62. When the two plates 201 are joined together, the inner wall of the disassembly / removal slot 61 on one plate 201 abuts against the chamfer 8 on the disassembly / removal latch 64, causing the disassembly / removal latch 64 to slide and retract into the disassembly / removal insert 62. Afterwards... The disassembly and assembly plug 62 is inserted into the disassembly and assembly slot 61. When the disassembly and assembly plug 62 is fully inserted into the disassembly and assembly slot 61, the disassembly and assembly latch 64 slides down under the drive of the drive mechanism 7 and is inserted into the disassembly and assembly latch 63. When it is necessary to disassemble the plate body 201, the drive block 72 is disengaged from the disassembly and assembly latch 64 by driving the drive rod 71 to slide. The disassembly and assembly latch 64 is stored in the disassembly and assembly plug 62 under the action of the return spring 9. At this time, the disassembly and assembly plug 62 can be removed from the disassembly and assembly slot 61.

[0037] Reference Figure 1 Both ends of the two end plates 1 are provided with fixing mechanisms 10 in the width direction. In this embodiment, three sets of fixing mechanisms 10 are provided at both ends of the end plates 1 in the width direction, and are provided with corresponding disassembly and assembly mechanisms 6. The fixing mechanism 10 includes a fixing groove 101, a fixing bolt 102 and a fixing nut 103. The fixing groove 101 is opened at one end of the width direction of the end plate 1. The fixing bolt 102 is placed in the fixing groove 101. The fixing nut 103 is threadedly connected to the fixing bolt 102. The distance between the two end plates 1 is adjusted and fixed by the fixing mechanism 10, so that the clamping of the heat sink 2 by the two end plates 1 is more stable.

[0038] Reference Figure 1 , Figure 4 and Figure 5After the disassembly and assembly mechanism 6 is installed and the heat sink 2 is spliced, a disassembly and assembly block 62 is fixed at one end in the width direction, and a disassembly and assembly slot 61 is opened at the other end. A reinforcing block 11 is inserted into one end of the heat sink 2 with the disassembly and assembly slot 61. The reinforcing block 11 has bolt holes 12. The fixing bolt 102 installed on the side of the heat sink 2 with the disassembly and assembly slot 61 passes through the bolt holes 12. The reinforcing block 11, by being inserted into the disassembly and assembly slot 61 and cooperating with the fixing bolt 102, can improve the overall structural strength of the end plate 1 and the heat sink 2, and reduce the probability of the heat sink 2 sliding in the end plate 1. The fixing bolt 102 installed on the side of the heat sink 2 with the disassembly and assembly block 62 abuts against the disassembly and assembly block 62 and drives the drive rod 71 to slide and be stored in the disassembly and assembly block 62. A drive wedge 13 is fixed on the drive rod 71. When the drive rod 71 is stored in the disassembly and assembly latch 64, the drive wedge 13... The drive wedge 13 drives the disassembly and assembly block 64 to be inserted into the disassembly and assembly slot 63. After the heat sink 2 is installed in the plate 201, the drive wedge 13, in conjunction with the fixing bolt 102, can fix the disassembly and assembly block 64 in the disassembly and assembly slot 63, while reducing the probability of the disassembly and assembly block 64 being dislodged from the disassembly and assembly slot 63 by external force. The reinforcing block 11 is slidably provided with a reinforcing block 14. When the drive rod 71 extends into the disassembly and assembly slot 61, it is inserted into the reinforcing block 11 and drives the reinforcing block 14 to slide into the disassembly and assembly slot 63. At the same time as the fixing bolt 102 pushes the drive rod 71 to slide, the drive rod 71 is inserted into the reinforcing block 11, so that the reinforcing block 14 in the reinforcing block 11 slides and is locked in the disassembly and assembly slot 63 to reinforce the reinforcing block 11, reduce the probability of the reinforcing block 11 being dislodged from the plate 201, and thus improve the strength of the reinforcing block 11 installation structure.

[0039] Reference Figure 1 , Figure 2 and Figure 3Several heat exchange tubes 3 extend through end plates 1 at both ends along their length. Both ends of the heat exchange tubes 3 are connected to a main pipe 15. Interfaces 16 are fixed to the main pipe 15, and several connecting pipes 17 are fixed to the main pipe 15 corresponding to the heat exchange tubes 3. A fixed threaded sleeve 18 is rotatably mounted on each connecting pipe 17. After the heat exchange tube 3 is inserted into the connecting pipe 17, the fixed threaded sleeve 18 is rotated to thread it onto the heat exchange tube 3, thus fixing the heat exchange tube 3 to the connecting pipe 17. A sealing rubber ring 19 is fixed to the inner wall of the connecting pipe 17, abutting against the outer wall of the heat exchange tube 3 to seal the connection between the heat exchange tube 3 and the connecting pipe 17. Interfaces 16 connect to equipment on the ship requiring heat exchange or to pumping equipment. Connecting heat exchange tubes 3 with the same function through the main pipe 15 facilitates control of the same function. The connection between the heat exchange tube 3 and the main pipe 15 reduces the probability of the left half pipe 31 and the right half pipe 32 detaching from each other. A fixing ring 20 is detachably installed on the end plate 1. The fixing ring 20 fixes the main pipe 15 to the end plate 1. There is one fixing ring 20 at each end of the length direction of the main pipe 15. By installing the fixing ring 20, the main pipe 15 is fixed to the end plate 1, reducing the probability of the main pipe 15 falling off and improving the installation strength of the main pipe 15. In this embodiment, one end of the fixing ring 20 is hinged to the end plate 1, and the other end is detachably installed to the end plate 1 by bolts. A pressure-reducing layer 21 is provided on the inner wall of the fixing ring 20. The pressure-reducing layer 21 is made of a high-temperature resistant flexible material, such as modified rubber. The pressure-reducing layer 21 can reduce the pressure of the fixing ring 20 on the main pipe 15 and reduce the probability of the fixing ring 20 damaging the main pipe 15.

[0040] Reference Figure 1 and Figure 6A support frame 22 is rotatably mounted on end plate 1. A sliding groove 23 is provided on end plate 1, and a sliding block 24 is slidably mounted within the sliding groove 23. The support frame 22 is hinged to the sliding block 24 and slidably rotates within the sliding groove 23. The sliding groove 23 includes a vertical groove 231 and a horizontal groove 232. The vertical groove 231 is vertically located on end plate 1, and the horizontal groove 232 is horizontally located on end plate 1. Several horizontal grooves 232 are evenly distributed along the length of the vertical groove 231 and are all connected to the vertical groove 231. When the sliding block 24 slides into the horizontal groove 232, the height of the support frame 22 is fixed. The support frame 22 provides support, reducing the probability of the heat exchanger tipping over. By adjusting the height of the support frame 22 through the sliding of the sliding block 24, the center of gravity of the support can be adjusted according to actual needs, thereby improving the support effect of the support frame 22. When the sliding block 24 is located at the bottom of the vertical groove 231, the support frame 22 rotates to fit the ground. By placing a counterweight on the support frame 22, the probability of the heat exchanger sliding under force can be reduced. In this embodiment, the cross-section of the sliding block 24 is T-shaped, and the cross-section of the sliding groove 23 is also T-shaped. The T-shaped sliding groove 23 can cooperate with the T-shaped sliding block 24 to slide while reducing the probability of the sliding block 24 detaching. In this embodiment, the support frame 22 includes two support rods 221 and two connecting plates 222. Two sliding grooves 23 are provided for the support rods 221, and two sliding blocks 24 are provided for the support rods 221. The two support rods 221 are respectively hinged to the two sliding blocks 24. The two connecting plates 222 are connected between the two support rods 221. The connecting plates 222 are used to improve the structural strength of the support rods 221 and provide placement space when placing the counterweight.

[0041] The implementation principle of this application embodiment is as follows: The heat exchange tubes 3 to be used are assembled by splicing the left half tube 31 and the right half tube 32. Then, several heat exchange tubes 3 are assembled on the heat sink 2 by splicing the plates 201. When splicing the plates 201, the disassembly and assembly inserts 62 of the adjacent plates 201 are inserted into the disassembly and assembly slots 61, and the disassembly and assembly clips 64 slide into the disassembly and assembly slots 63 to temporarily fix the adjacent plates 201. Then, the reinforcing plate is inserted into one end of the disassembly and assembly slots 61 of the spliced ​​heat sink 2. Two end plates 1 are installed on both sides of the thickness direction of the heat sink 2. The end plates 1 are installed so that the heat exchange tubes 3 pass through the installation holes on the end plates 1. Then, a fixing bolt 102 is installed on one end of the disassembly and assembly inserts 62 fixed on the heat sink 2, and a fixing nut 103 is installed on the fixing bolt 102. The fixing bolt 102 abuts against the drive rod 71 to make the drive rod 71 slide. The drive rod 71 drives all the drive rods 71 ​​in the heat sink 2 to slide synchronously, and makes the drive rod 71 slide synchronously. The drive wedge 13 on the rod 71 abuts against the disassembly / removal latch 64, preventing the disassembly / removal latch 64 from disengaging from the disassembly / removal slot 63. The end of the drive rod 71 away from the disassembly / removal insert 62 slides into the disassembly / removal slot 61 and inserts into the reinforcing block 11. The reinforcing latch 14 inside the reinforcing block 11 is then inserted into the disassembly / removal slot 63. A fixing bolt 102 is then installed at one end of the disassembly / removal slot 61 on the heat sink 2. The fixing bolt 102 passes through the reinforcing block 11 and is then secured by a fixing nut 103. Install main pipes 15 at both ends of heat exchange tube 3, and reinforce the main pipes 15 to end plate 1 with fixing rings 20 to complete the assembly of the heat exchanger. When the heat exchanger is in use, rotate the support frame 22 to support the heat exchanger in the working position according to actual needs. When the scaling inside the heat exchange tube 3 is serious, disassemble the heat exchanger and disassemble the heat exchange tube 3 to clean and remove the scale inside the heat exchange tube 3. When the heat exchange tube 3 is damaged, the damaged heat exchange tube 3 can be replaced by disassembling the heat exchanger.
