Description

Technical Field

[0001] This utility model relates to the field of indirect heat exchanger technology, and in particular to a marine indirect heat exchanger. Background Technology

[0002] A partition wall heat exchanger is a heat exchange device that achieves indirect heat exchange. When a partition wall heat exchanger is exchanging heat, the solid wall completely separates the hot and cold fluids, and heat is transferred from the high-temperature fluid to the low-temperature fluid through the wall by means of conduction and convection.

[0003] A related technology, Chinese Patent No. CN214250635U, discloses a compact air-cooled heat exchanger for ships. It includes a housing with an air inlet pipe connected to one side wall, inside which a fan is installed. An air outlet pipe is connected to the other side wall. An opening A is provided on the upper surface of the housing, extending into the housing and connected to a first connecting pipe. An opening B is provided on the lower surface of the housing, extending into the housing and connected to a second connecting pipe. Several evenly distributed conveying pipes are vertically connected between the first and second connecting pipes. Several vertically arranged heat dissipation plates are horizontally inserted into the interior of each conveying pipe. The hot medium enters the conveying pipe through opening A, and cold air enters the housing through the air inlet pipe, allowing the hot medium and cold air to exchange heat within the housing. The hot air after heat exchange is output from the air outlet pipe, and the cooled hot medium is output from opening B. The bottom of the container is equipped with a mounting plate. Symmetrical through-slots are formed on the upper surface of the mounting plate, with a baffle fixedly connected to the middle section of each slot. Fixed corner brackets are fixedly connected at each of the four corner brackets, with fixed blocks connected to their bottoms. These fixed blocks are located inside the through-slots, and two strong spring rods, A and B, are respectively connected to their side walls. One end of strong spring rod A is connected to the inner wall of the through-slot, and one end of strong spring rod B is connected to the baffle. When the hull rocks, strong spring rods A and B extend under tension and contract under pressure, respectively, thus utilizing the spring force to counteract the rocking motion.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: when the hull sways, the elastic force of the strong spring rod A and the elastic force of the strong spring rod B are used to make the structure resist the swaying. However, when the hull swaying direction deviates from the direction of the spring rod elastic force by a large angle, the effect of using the strong spring rod A and the strong spring rod B to make the structure resist the swaying becomes worse, resulting in limited anti-vibration performance of the heat exchanger. Utility Model Content

[0005] To improve the seismic resistance of heat exchangers, this application provides a marine indirect heat exchanger.

[0006] The technical solution for a marine indirect heat exchanger provided in this application is as follows: A marine indirect heat exchanger includes a base and a heat exchange box. A refrigerant pipe and a heat exchanger pipe are installed inside the heat exchange box, with both ends of the refrigerant pipe and the heat exchanger pipe penetrating the heat exchange box. A mounting base is provided between the top of the base and the bottom of the heat exchange box. A vertical component is provided between the mounting base and the heat exchange box, providing vertical elasticity to the heat exchange box. A horizontal component is provided between the mounting base and the base, providing horizontal elasticity to the mounting base.

[0007] By adopting the above technical solution, the hot medium is introduced into the hot medium pipeline and the cold medium is introduced into the cold medium pipeline, so that the hot medium and the cold medium can exchange heat indirectly in the tank. The vertical component provides vertical elastic force to the heat exchange box, and the horizontal component provides horizontal elastic force to the mounting base. The vertical elastic force and the horizontal elastic force are combined to form a resultant force acting on the heat exchange box. When the ship sways and exerts a force on the heat exchange box, the force applied to the heat exchange box can be decomposed according to the horizontal direction of the horizontal component and the vertical direction of the vertical component. The elastic element in the vertical component deforms to absorb and consume the vertical kinetic energy, and the elastic component in the horizontal component deforms to absorb and consume the horizontal kinetic energy, thereby improving the seismic performance of the heat exchanger.

The bottom of the horizontal seat is fixedly connected to the top of the base. One end of the horizontal spring is fixedly connected to the inner wall of the horizontal seat, and the other end of the horizontal spring is fixedly connected to the outer ring wall of the horizontal seat. The horizontal springs are distributed circumferentially around the axis of the horizontal seat.

[0009] By adopting the above technical solution, the horizontal spring applies a horizontal elastic force to the mounting base.

[0010] Preferably, the mounting base has a limiting groove and a connecting groove. The top end of the connecting groove is connected to the limiting groove, and the bottom end of the connecting groove is connected to the horizontal groove. A limiting seat is movably disposed in the limiting groove. The top and bottom walls of the limiting seat are both in contact with the inner wall of the limiting groove.

A connecting seat is movably disposed in the connecting groove. There is a gap between the side wall of the connecting seat and the inner wall of the connecting groove. The top end of the connecting seat is fixedly connected to the limiting seat, and the bottom end of the connecting seat is fixedly connected to the horizontal seat.

[0011] By adopting the above technical solution, the horizontal seat is secured inside the mounting base by a limiting seat, reducing the possibility of the mounting base slipping off the horizontal seat.

Abutment screws are inserted into the through holes, and abutment blocks are fixedly installed on the end of the abutment screw facing the mounting base.

A set of abutment nuts are sleeved on the abutment screws, and the abutment nuts are threadedly connected to the abutment screws. The opposite side of the abutment nuts is used to abut against the brackets.

[0013] By adopting the above technical solution, the staff can adjust the distance between the abutment block and the mounting base according to the usage scenario. When all the abutment blocks are separated from the side wall of the mounting base, it is convenient for the mounting base to move in the horizontal direction. When the hull sways, the elastic component in the horizontal component can deform to absorb and consume horizontal kinetic energy. When all the abutment blocks are in contact with the side wall of the mounting base, the mounting base and the base remain relatively stationary. When the hull sways, the elastic component in the horizontal component cannot deform to absorb and consume horizontal kinetic energy.

[0014] Preferably, the longitudinal component includes several vertical springs, one end of which is fixedly connected to the heat exchange box, and the other end of which is fixedly connected to the mounting base.

[0016] Preferably, a protective shell is fixedly installed on the top of the mounting base, the protective shell is sleeved on the heat exchange box, the protective shell is slidably connected to the heat exchange box, the vertical springs are all located inside the protective shell, and a flexible pad is provided on the inner wall of the protective shell, the flexible pad is in contact with the outer wall of the heat exchange box.

[0017] By adopting the above technical solution, the flexible pad makes flexible contact between the protective shell and the heat exchange box. On the one hand, the protective shell protects the vertical spring, and on the other hand, it guides the heat exchange box, thereby improving the stability of the heat exchange box.

[0018] Preferably, a plurality of guide sleeves are fixedly provided on the side wall of the heat exchange box, and guide screws are inserted into the guide sleeves. The guide screws are slidably connected to the guide sleeves, and the bottom end of the guide screws is fixedly connected to the mounting base. A set of guide nuts are threaded onto the guide screws, and the opposite surfaces of the guide nuts are used to abut against the guide sleeves.

[0019] By adopting the above technical solution, the staff can adjust the position of the guide nut on the guide screw according to the usage scenario. When the guide nut is separated from the guide sleeve, it is convenient for the heat exchange box to move in the vertical direction. When the hull is rocking, the elastic component in the vertical assembly can deform to absorb and consume horizontal kinetic energy. When the guide sleeve is clamped by the guide nut, the mounting base and the heat exchange box remain relatively stationary. When the hull is rocking, the elastic component in the vertical assembly cannot deform to absorb and consume horizontal kinetic energy.

[0020] Preferably, the base has several threaded holes through it.

[0021] By adopting the above technical solution, the user can fix the base in the corresponding position inside the cabin through the threaded hole.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1.

Abutment blocks 82 are mounted on the end of the abutment screws 8 facing the mounting base 3, and the abutment blocks 82 abut against the side wall of the mounting base 3. A set of abutment nuts 81 are fitted onto the abutment screws 8, and the abutment nuts 81 are threadedly connected to the abutment screws 8. The opposite face of the abutment nuts 81 abuts against the brackets 83. Rotating the abutment nuts 81 adjusts the relative position of the abutment screws 8 and the brackets 83, allowing the operator to adjust the distance between the abutment blocks 82 and the mounting base 3 according to the usage scenario. When all the abutment blocks 82 are separated from the side wall of the mounting base 3, the mounting base 3 can move horizontally.

By rotating the guide nuts 91, the operator can adjust the position of the guide nuts 91 on the guide screw 9 according to the usage scenario. When the guide nuts 91 are separated from the guide sleeves 92, it is convenient for the heat exchange box 2 to move in the vertical direction. When the hull is rocking, the elastic component in the vertical assembly 4 can deform to absorb and dissipate horizontal kinetic energy. When the guide sleeve 92 is clamped by the guide nuts 91, the mounting base 3 and the heat exchange box 2 remain relatively stationary. When the hull is rocking, the elastic component in the vertical assembly 4 cannot deform to absorb and dissipate horizontal kinetic energy.

[0037] The implementation principle of a marine indirect heat exchanger according to an embodiment of this application is as follows: a hot medium is introduced into a hot medium pipe 22, and a cold medium is introduced into a cold medium pipe 21, allowing indirect heat exchange between the hot and cold media within the tank. When the ship's hull sways and exerts a force on the heat exchange tank 2, the force applied to the heat exchange tank 2 can be decomposed according to the elastic force direction of the horizontal spring 51 and the elastic force direction of the vertical spring 41. The vertical spring 41 deforms to absorb and dissipate the kinetic energy in the vertical direction, and the horizontal spring 51 deforms to absorb and dissipate the kinetic energy in the horizontal direction, thereby improving the seismic resistance of the heat exchanger.
