Description

Technical Field

[0001] The present invention relates to the technical field of heat pump units, and more particularly to an ultra-high temperature heat pump unit using a plate-shell heat exchanger with a liquid accumulator function. Background Art

[0002] An ultra-high temperature heat pump unit is a device that can convert low-temperature heat energy into high-temperature heat energy. For example, a water-cooled screw ultra-high temperature heat pump unit with a patent publication number of CN211120087U includes a water storage tank, a first heat exchanger, and a second heat exchanger. A first heat exchange tube is installed inside the first heat exchanger, and a second heat exchange tube is installed inside the second heat exchanger. The first heat exchange tube and the second heat exchange tube are arranged in a circular spiral. One end of the first heat exchange tube is connected to a first intake pipe, and the other end of the first heat exchange tube is connected to a first outlet pipe. One end of the first outlet pipe is connected to a second inlet pipe and a third outlet pipe through a three-way pipe. One end of the second inlet pipe is connected to the second heat exchange tube, and the other end of the second heat exchange tube is connected to a second outlet pipe. By providing the first heat exchanger and the second heat exchanger, two heat exchange processes can be carried out, two groups of water bodies with different temperatures can be heated for use, and the high-temperature waste hot gas can be cooled twice, and the cooling effect is good.

[0003] In order to improve the performance of the ultra-high temperature heat pump unit, through effective cooling, it is possible to ensure that the high-temperature and high-pressure gas in the condenser fully releases heat, thereby improving the energy efficiency ratio of the unit. During the operation of the ultra-high temperature heat pump unit, a gaseous refrigerant needs to be used for heat exchange. However, the gaseous refrigerant will form a liquid after heat exchange, and then an additional liquid accumulator is required for liquid storage, which increases the internal volume of the system. An overly large volume increases the operating cost and floor area of the unit. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an ultra-high temperature heat pump unit using a plate-shell heat exchanger with a liquid accumulator function, which solves the problem that the existing ultra-high temperature heat pump unit requires an additional liquid accumulator, resulting in an increase in the internal volume of the system.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] An ultra-high temperature heat pump unit using a plate-shell heat exchanger with a liquid accumulator function includes a compressor. The exhaust port of the compressor is connected to the inlet of an oil separator through a pipeline. An oil heater is installed inside the oil separator. The discharge port of the oil heater is connected to an oil cooler and the oil hole of the compressor through a pipeline. The condensation hole of the oil separator is connected to an intake pipe through a pipeline and then connected to a condenser. The condenser is sequentially connected to a refrigerant filter, an electronic expansion valve, and the inlet of an evaporator through a drain pipe. The outlet of the evaporator is connected to the compressor through pipelines respectively. An air pump is arranged between the evaporator and the compressor.

[0007] The condenser includes a container housing. An irregular liquid storage tank for receiving liquid is integrally provided at the bottom of the container housing. Flange covers are installed on both sides of the container housing. A heat exchange component for heat exchange is installed between the two flange covers. An air inlet pipe is provided at the upper end of the container housing. A drain pipe is provided at the bottom of the irregular liquid storage tank. A pressure sensor for detecting gas is installed inside the container housing. A liquid level sensor for detecting liquid is installed inside the irregular liquid storage tank.

[0008] Preferably, side baffles for preventing gas leakage on both sides are provided on the inner wall of the container housing, and filling seats for preventing gas leakage at both ends are provided on the surface of the flange covers.

[0009] Preferably, the heat exchange component includes a delivery pipe. The body of the delivery pipe is rotatably installed at the center of the flange cover. A number of heat exchange plates for heat exchange reaction with gas are provided on the body of the delivery pipe. An installation hole for installing on the body of the delivery pipe is provided in the middle of the body of the heat exchange plate. Connecting sleeves for connecting pipelines are rotatably installed at both ends of the delivery pipe respectively.

[0010] Preferably, a partition plate is integrally provided inside the delivery pipe. A number of discharge ports are provided at the upper end of the delivery pipe. A number of inlet ports are provided at the lower end of the delivery pipe. The number of inlet ports is the same as that of the discharge ports. A group of heat exchange plates is provided outside adjacent two inlet ports and discharge ports.

[0011] Preferably, every two of the heat exchange plates are combined together. Diffusion cavities and concentration cavities are respectively provided on the inner walls of the two heat exchange plates on both sides. A blocking plate is fixedly installed between the diffusion cavity and the concentration cavity. An exchange port is provided outside the blocking plate.

[0012] Preferably, a first guiding plate is installed inside the diffusion cavity, and a second guiding plate is installed inside the concentration cavity. One end of the diffusion cavity communicates with the discharge port, and one end of the concentration cavity communicates with the inlet port.

[0013] Preferably, a bracket is fixedly installed outside one of the flange covers, and a motor is fixedly installed inside the bracket.

[0014] Preferably, a transmission gear is fixedly installed at the output end of the motor, and a driven gear is fixedly installed on the body of the delivery pipe. The driven gear and the transmission gear are meshed for transmission.

[0015] Preferably, an auxiliary component for guiding gas is provided below the air inlet pipe. The auxiliary component includes slide rails. There are two slide rails and they are respectively fixedly installed on the inner wall of the container housing. The slide rails are located above the side baffles. A dispersion guide plate for guiding the direction of gas is provided in the middle of the slide rails.

[0016] Preferably, insertion plates are fixedly installed on both sides of the dispersion guide plate. A movable seat is movably installed inside the slide rail. A slot is formed inside the movable seat. The slot is movably connected to the insertion plate. A support spring is installed between the movable seat and the slide rail.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By providing a special-shaped liquid storage tank at the bottom of the container housing, when the gaseous refrigerant enters the container housing from the intake pipe and exchanges heat, the gaseous refrigerant will form a liquid after heat exchange and then fall and be stored in the special-shaped liquid storage tank. Compared with the existing unit heat exchanger and liquid storage device being separate and independent and requiring connection between them, by integrating the special-shaped liquid storage tank into the container housing in this application, one pressure vessel can be reduced. Without an additional liquid storage device, the internal volume of the system is reduced, and the refrigerant charge is significantly reduced, simplifying the system, effectively reducing the operating cost and floor area.

[0019] 2. The pressure sensor can be used to detect the current pressure inside the container housing in real time to control the addition of the gaseous refrigerant, and the liquid level sensor can be used to detect the liquid level of the special-shaped liquid storage tank in real time, avoiding excessive formation of liquid by the gaseous refrigerant, preventing excessive liquid and avoiding the liquid level from submerging the heat exchange plate, and being controlled by the liquid level sensor and the pressure sensor.

[0020] 3. During heat exchange, the fluid to be heated will, under the guidance of the sealing plate, enter the inlet from the delivery pipe and then turn into the diffusion cavity. As the heat exchange plate rotates, the fluid extends outward, and the gaseous refrigerant at the current position undergoes a heat exchange reaction. The gaseous refrigerant forms a liquid, and the fluid is heated. During the heat exchange process, the fluid will enter the central cavity through the exchange port. By setting the second guide plate and the first guide plate in opposite directions, the fluid will be concentrated towards the discharge port after passing through the exchange port, enabling the heated fluid to turn into the discharge port and then be discharged from the other end of the delivery pipe to achieve the heat exchange operation.

[0021] 4. Since part of the liquid will remain on the surface of the heat exchange plate after the gaseous refrigerant exchanges heat with the heat exchange plate, resulting in too slow a falling speed of the liquid and being unfavorable for rapid heat exchange operation, the motor is started to drive the transmission gear to rotate, and the transmission gear and the driven gear rotate, thereby driving the body of the delivery pipe to rotate and flinging the liquid on the surface of the heat exchange plate outward to accelerate the discharge of the liquid. The liquid will be discharged downward under the limitation of the side baffle, increasing the falling speed of the liquid after heat exchange. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0040] As Figures 1 to 16 shown, a ultra-high temperature heat pump unit using a plate-shell heat exchanger with a liquid storage function includes a compressor 10. The exhaust port of the compressor 10 is connected to the inlet of an oil separator 11 through a pipeline. An oil heater 12 is installed inside the oil separator 11. The drain outlet of the oil heater 12 is connected to an oil cooler 13 and then to the oil hole of the compressor 10 through a pipeline. The condensation hole of the oil separator 11 is connected to an intake pipe 5 through a pipeline and then to a condenser 14. The condenser 14 is successively connected to a refrigerator filter 15, an electronic expansion valve 16 and the inlet of an evaporator 17 through a drain pipe 6. The outlet of the evaporator 17 is connected to the compressor 10 through pipelines respectively. An air pump 18 is arranged between the evaporator 17 and the compressor 10;

[0041] The condenser 14 includes a container housing 1. A special-shaped liquid storage tank 3 for receiving liquid is integrally arranged at the bottom of the container housing 1. Flange covers 2 are installed on both sides of the container housing 1. A heat exchange component 4 for heat exchange is installed between the two flange covers 2. An intake pipe 5 is arranged at the upper end of the container housing 1. A drain pipe 6 is arranged at the bottom of the special-shaped liquid storage tank 3. A pressure sensor 7 for detecting gas is installed inside the container housing 1. A liquid level sensor 8 for detecting liquid is installed inside the special-shaped liquid storage tank 3.

[0042] In this application, a special-shaped liquid storage tank 3 is provided at the bottom of the container housing 1. When the gaseous refrigerant enters the container housing 1 from the intake pipe 5 and exchanges heat, the gaseous refrigerant will form a liquid after heat exchange and then fall and be stored in the special-shaped liquid storage tank 3. Compared with the existing unit, the heat exchanger and the liquid storage device are separate and independent, and a connection needs to be made between them. By integrating the special-shaped liquid storage tank 3 into the container housing 1 in this application, one pressure vessel can be reduced. Without an additional liquid storage device, the internal volume of the system is reduced, and the refrigerant charge is significantly reduced, simplifying the system, effectively reducing the operating cost and floor area.

[0043] The pressure sensor 7 can be used to detect the internal pressure of the current container housing 1 in real time to control the addition of the gaseous refrigerant. And the liquid level sensor 8 can perform real-time liquid level detection on the special-shaped liquid storage tank 3 to prevent excessive liquid formation of the gaseous refrigerant, avoid excessive liquid, and prevent the liquid level from submerging the heat exchange plate 407, and is controlled by the liquid level sensor 8 and the pressure sensor 7.

[0044] In this embodiment, side baffles 101 for preventing gas leakage on both sides are provided on the inner wall of the container housing 1, and filling seats 201 for preventing gas leakage at both ends are provided on the surface of the flange cover 2.

[0045] To ensure that the gaseous refrigerant can cooperate with the heat exchange component 4, the side baffles 101 can limit the gas on both sides, and the filling seats 201 limit the gas at both ends, thereby controlling the heat exchange range of the gas and avoiding the problem that some gas cannot be heat exchanged in time due to gas leakage. During the heat exchange process, the heat exchange plate 407 is close to the side baffle 101, and a water seal is formed between them by the formed liquid to reduce gas leakage.

[0046] In this embodiment, the heat exchange component 4 includes a delivery pipe 401. The body of the delivery pipe 401 is rotatably installed at the center of the flange cover 2. A number of heat exchange plates 407 for heat exchange reaction with the gas are provided on the body of the delivery pipe 401. An installation hole 4071 for installing on the body of the delivery pipe 401 is provided in the middle of the body of the heat exchange plate 407. Connecting sleeves 402 for connecting pipes are rotatably installed at both ends of the delivery pipe 401 respectively.

[0047] Before use, both ends of the delivery pipe 401 are connected to the external pipes through the connecting sleeves 402, and the connecting sleeves 402 can be used to enable the delivery pipe 401 to rotate independently without affecting subsequent delivery and heat exchange reaction.

[0048] In the present application, a partition plate 4011 is integrally provided inside the conveying pipe 401. A plurality of discharge ports 403 are provided at the upper end of the conveying pipe 401, and a plurality of inlet ports 404 are provided at the lower end of the conveying pipe 401. The number of inlet ports 404 is the same as that of the discharge ports 403. A group of heat exchange plates 407 are arranged outside two adjacent inlet ports 404 and discharge ports 403.

[0049] Every two heat exchange plates 407 are combined together. Diffusion cavities 4072 and concentration cavities 4077 are respectively formed in the inner walls of the two side heat exchange plates 407. A blocking plate 4074 is fixedly installed between the diffusion cavity 4072 and the concentration cavity 4077. An exchange port 4075 is formed outside the blocking plate 4074.

[0050] A first guiding plate 4073 is installed inside the diffusion cavity 4072, and a second guiding plate 4076 is installed inside the concentration cavity 4077. One end of the diffusion cavity 4072 communicates with the discharge port 403, and one end of the concentration cavity 4077 communicates with the inlet port 404.

[0051] During heat exchange, the fluid to be heated will enter the inlet port 404 from the conveying pipe 401 under the guidance of the blocking plate 4074, and then enter the diffusion cavity 4072. As the heat exchange plate 407 rotates, the fluid extends outward, and a heat exchange reaction occurs between the gaseous refrigerant at the current position. The gaseous refrigerant forms a liquid, and the fluid is heated. During the heat exchange process, the fluid will enter the concentration cavity 4077 through the exchange port 4075. Since the second guiding plate 4076 and the first guiding plate 4073 are arranged in opposite directions, the fluid will be concentrated towards the discharge port 403 after passing through the exchange port 4075, so that the heated fluid enters the discharge port 403, and then is discharged from the other end of the conveying pipe 401 to complete the heat exchange operation.

[0052] In this embodiment, a bracket 405 is fixedly installed outside one of the flange covers 2, and a motor 4051 is fixedly installed inside the bracket 405.

[0053] A transmission gear 4052 is fixedly installed at the output end of the motor 4051, and a driven gear 406 is fixedly installed on the pipe body of the conveying pipe 401. The driven gear 406 is in meshing transmission with the transmission gear 4052.

[0054] Since the gaseous refrigerant forms a liquid after exchanging heat with the heat exchange plate 407, some liquid will remain on the surface of the heat exchange plate 407, resulting in an overly slow falling speed of the liquid, which is not conducive to rapid heat exchange operations. Therefore, the motor 4051 is started to drive the transmission gear 4052 to rotate, and the transmission gear 4052 and the driven gear 406 rotate, thereby driving the body of the delivery pipe 401 to rotate, and the liquid on the surface of the heat exchange plate 407 is thrown outwards, accelerating the discharge of the liquid. The liquid will be discharged downward under the limit of the side baffle 101, increasing the falling speed of the liquid after heat exchange.

[0055] When specifically arranged, an auxiliary component 9 for guiding gas is provided below the intake pipe 5. The auxiliary component 9 includes slide rails 901. There are two slide rails 901, which are respectively fixedly installed on the inner wall of the container housing 1. The slide rails 901 are located above the side baffle 101, and a dispersion guide plate 903 for guiding the gas direction is provided in the middle of the slide rails 901.

[0056] Among them, insertion plates 902 are fixedly installed on both sides of the dispersion guide plate 903. A movable seat 906 is movably installed inside the slide rail 901. A slot 905 is opened inside the movable seat 906. The slot 905 is movably connected to the insertion plate 902. A support spring 904 is installed between the movable seat 906 and the slide rail 901.

[0057] After the gaseous refrigerant is discharged from the intake pipe 5, in order to prevent the range through which the gaseous refrigerant passes from being only at the intake pipe 5, resulting in the refrigerant only performing heat exchange reactions on the middle heat exchange plate 407 while the heat exchange efficiency of the heat exchange plates 407 on both sides decreases, the currently discharged gas can be guided by the dispersion guide plate 903, causing the gas to diffuse to both sides and preventing the gas from concentrating in the middle.

[0058] Among them, the gas discharge amount varies according to needs. In order to prevent the distance between the dispersion guide plate 903 and the intake pipe 5 from being too small when the gas discharge amount is large, affecting the discharge speed, a support spring 904 is installed between the movable seat 906 and the slide rail 901, enabling the dispersion guide plate 903 to contract the support spring 904 when the gas discharge amount is too large, thereby increasing the distance to facilitate the smoother discharge of the gas.

[0059] The working principle of a super-high temperature heat pump unit using a plate-and-shell heat exchanger with a liquid storage function:

[0060] First, gaseous refrigerant is added through the intake pipe 5. Among them, the currently discharged gas can be guided by the dispersion guide plate 903, causing the gas to diffuse to both sides and preventing the gas from concentrating in the middle.

[0061] During heat exchange, the fluid to be heat-exchanged will, under the guidance of the sealing plate 4074, enter the inlet 404 from the delivery pipe 401, and then transfer to the diffusion cavity 4072. As the heat exchange plate 407 rotates, the fluid extends outward, and the gaseous refrigerant at the current position undergoes a heat exchange reaction, turning the gaseous refrigerant into a liquid while the fluid is heat-exchanged. During the heat exchange process, the fluid will enter the centralized cavity 4077 through the exchange port 4075. By setting the second guiding plate 4076 opposite to the first guiding plate 4073, the fluid will be concentrated towards the discharge port 403 after passing through the exchange port 4075, causing the heat-exchanged fluid to transfer to the discharge port 403 and then be discharged from the other end of the delivery pipe 401 to achieve the heat exchange operation;

[0062] During the heat exchange process, the motor 4051 is started to drive the driving gear 4052 to rotate, causing the driving gear 4052 to rotate with the driven gear 406, thereby driving the body of the delivery pipe 401 to rotate and causing the liquid on the surface of the heat exchange plate 407 to be thrown outward, accelerating the discharge of the liquid. The discharged liquid will fall into the special-shaped liquid storage tank 3 and then be discharged through the drain pipe 6.

[0063] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to enumerate all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
