[0013] Preferably, an auxiliary component for guiding gas is provided below the air inlet pipe, and the auxiliary component includes a slide rail. Two slide rails are provided and are respectively fixedly mounted on the inner wall of the container shell.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By providing a special-shaped liquid storage tank at the bottom of the container shell, when the gaseous refrigerant enters the container shell from the air inlet pipe and exchanges heat, the gaseous refrigerant will form a liquid after the 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 are separate and independent, and need to be connected, by integrating the special-shaped liquid storage tank of the present application into the container shell, a pressure vessel can be reduced, there is no additional liquid storage tank, the system volume is reduced, and the refrigerant filling amount is significantly reduced, so that the system is simplified, and the operating cost and floor space are effectively reduced.

[0016] 2. The pressure sensor can detect the current internal pressure of the container shell in real time to control the addition of gaseous refrigerant, and the liquid level sensor can detect the liquid level of the special-shaped liquid storage tank in real time to avoid the formation of excessive liquid from the gaseous refrigerant, resulting in excessive liquid and the liquid level flooding the heat exchange plate, and control is performed through the liquid level sensor and pressure sensor.

[0017] 3. During heat exchange, the heat exchange fluid will enter the inlet from the delivery pipe under the guidance of the sealing plate, and then transfer to 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 becomes liquid, and the fluid is heat exchanged. During the heat exchange process, the fluid will enter the concentrated cavity through the exchange port, wherein the second guide plate and the first guide plate are arranged in opposite directions, so that the fluid will be concentrated to the discharge port after passing through the exchange port, so that the fluid after heat exchange is transferred to the discharge port, and then discharged from the other end of the delivery pipe to realize the heat exchange operation.

[0018] 4. Since the gaseous refrigerant will form liquid after heat exchange with the heat exchange plate, some of the liquid will remain on the surface of the heat exchange plate, which will cause the liquid to fall too slowly, which is not conducive to rapid heat exchange operation. Therefore, the transmission gear is driven to rotate by starting the motor, and the transmission gear and the driven gear are rotated, thereby driving the conveying pipe body to rotate, and the liquid on the surface of the heat exchange plate is thrown outward, accelerating the discharge of the liquid. The liquid will be discharged downward under the limit of the side baffle, thereby increasing the falling speed of the liquid after heat exchange. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 16 As shown, an ultra-high temperature heat pump unit using a plate and 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 exhaust port of the oil heater 12 is connected to the oil cooler 13 and the oil hole of the compressor 10 through a pipeline, the condensation hole of the oil separator 11 is connected to the condenser 14 through a pipeline and an air inlet pipe 5, the condenser 14 is connected to the refrigerator filter 15, the electronic expansion valve 16 and the inlet of the evaporator 17 in sequence through a liquid discharge pipe 6, the outlet of the evaporator 17 is connected to the compressor 10 through pipelines, and an air pump 18 is arranged between the evaporator 17 and the compressor 10; The condenser 14 includes a container shell 1, a special-shaped liquid storage tank 3 for receiving liquid is integrated at the bottom of the container shell 1, flange covers 2 are installed on both sides of the container shell 1, a heat exchange component 4 for heat exchange is installed between the two flange covers 2, an air inlet pipe 5 is arranged at the upper end of the container shell 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 shell 1, and a liquid level sensor 8 for detecting liquid is installed inside the special-shaped liquid storage tank 3.

[0023] The present application provides a special-shaped liquid storage tank 3 at the bottom of the container shell 1, so that when the gaseous refrigerant enters the container shell 1 from the air inlet pipe 5 and performs heat exchange, the gaseous refrigerant will become liquid after heat exchange, and then fall into the special-shaped liquid storage tank 3. Compared with the existing unit heat exchanger and liquid storage tank being separate and independent and requiring connection, the special-shaped liquid storage tank 3 of the present application is integrated into the container shell 1, which can reduce one pressure vessel, wherein there is no additional liquid storage tank, reduces the system internal volume, and significantly reduces the refrigerant filling amount, so that the system is simplified, and the operating cost and floor space are effectively reduced; The pressure sensor 7 can be used to detect the current internal pressure of the container shell 1 in real time to control the addition of gaseous refrigerant, and the liquid level sensor 8 can be used to perform real-time liquid level detection on the special-shaped liquid storage tank 3 to prevent the gaseous refrigerant from forming too much liquid, resulting in excessive liquid, and to prevent the liquid level from submerging the heat exchange plate 407, and control is performed through the liquid level sensor 8 and the pressure sensor 7.

[0024] In this embodiment, the inner wall of the container shell 1 is provided with a side baffle 101 for preventing gas leakage at both sides, and the surface of the flange cover 2 is provided with a filling seat 201 for preventing gas leakage at both ends.

[0025] In order to ensure that the gaseous refrigerant can cooperate with the heat exchange component 4, the side baffle 101 can limit the two sides of the gas, and the filling seat 201 can limit the two ends of the gas, so as to control the heat exchange range of the gas and avoid the problem of some gas not being able to exchange heat in time due to gas leakage. During the heat exchange process, the heat exchange plate 407 is close to the side baffle 101, and the formed liquid is used to form a water seal between them to reduce gas leakage.

[0026] In this embodiment, the heat exchange component 4 includes a delivery pipe 401, the body of the delivery pipe 401 is rotatably installed in the center of the flange cover 2, the body of the delivery pipe 401 is provided with a plurality of heat exchange plates 407 for heat exchange reaction with the gas, and the middle part of the body of the heat exchange plate 407 is provided with a mounting hole 4071 for installation on the body of the delivery pipe 401, and adapter sleeves 402 for connecting pipelines are rotatably installed at both ends of the delivery pipe 401.

[0027] Before use, both ends of the delivery tube 401 are connected to external pipelines through the adapter sleeve 402, and the adapter sleeve 402 can be used to enable the delivery tube 401 to rotate independently without affecting subsequent delivery and heat exchange reactions.

[0028] In the present application, a partition plate 4011 is integrated inside the delivery pipe 401, a plurality of discharge ports 403 are opened at the upper end of the delivery pipe 401, a plurality of inlets 404 are opened at the lower end of the delivery pipe 401, the number of inlets 404 and the number of discharge ports 403 are the same, and a group of heat exchange plates 407 are arranged outside two adjacent inlets 404 and discharge ports 403; Every two heat exchange plates 407 are combined together, and the inner walls of the heat exchange plates 407 on both sides are respectively provided with a diffusion cavity 4072 and a concentration cavity 4077, a blocking plate 4074 is fixedly installed between the diffusion cavity 4072 and the concentration cavity 4077, and an exchange port 4075 is provided on the outer side of the blocking plate 4074; A first guide plate 4073 is installed inside the diffusion cavity 4072 , a second guide plate 4076 is installed inside the concentration cavity 4077 , one end of the diffusion cavity 4072 is communicated with the discharge port 403 , and one end of the concentration cavity 4077 is communicated with the inlet 404 .

[0029] During heat exchange, the heat exchanged fluid will enter the inlet 404 from the delivery pipe 401 under the guidance of the sealing plate 4074, 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, the gaseous refrigerant becomes liquid, and the fluid is heat exchanged. During the heat exchange process, the fluid will enter the concentration cavity 4077 through the exchange port 4075, wherein the second guide plate 4076 and the first guide plate 4073 are arranged in opposite directions, so that the fluid will be concentrated to the discharge port 403 after passing through the exchange port 4075, so that the fluid after heat exchange is transferred to the discharge port 403, and then discharged from the other end of the delivery pipe 401, thereby realizing the heat exchange operation.

[0030] In this embodiment, a bracket 405 is fixedly installed on the outside of one of the flange covers 2, and a motor 4051 is fixedly installed inside the bracket 405; 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 body of the delivery tube 401 . The driven gear 406 is meshed with the transmission gear 4052 for transmission.

[0031] Since the gaseous refrigerant will form liquid after the heat exchange with the heat exchange plate 407, some of the liquid will remain on the surface of the heat exchange plate 407, which will cause the liquid to fall too slowly, which is not conducive to rapid heat exchange operation. Therefore, the starting motor 4051 is used to drive the transmission gear 4052 to rotate, and the transmission gear 4052 and the driven gear 406 are rotated, thereby driving the tube body of the delivery pipe 401 to rotate, and the liquid on the surface of the heat exchange plate 407 is thrown out to accelerate the discharge of the liquid. The liquid will be discharged downward under the limit of the side baffle 101, thereby increasing the falling speed of the liquid after heat exchange.

[0032] In the specific setting, an auxiliary component 9 for guiding the gas is provided under the air inlet pipe 5, and the auxiliary component 9 includes a slide rail 901. Two slide rails 901 are provided and are respectively fixedly installed on the inner wall of the container shell 1. The slide rail 901 is located on the upper side of the side baffle 101, and a dispersion guide plate 903 for guiding the direction of the gas is provided in the middle of the slide rail 901.

[0033] Among them, plug 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 plug plates 902, and a support spring 904 is installed between the movable seat 906 and the slide rail 901.

[0034] After the gaseous refrigerant is discharged from the air inlet pipe 5, in order to avoid the range of the gaseous refrigerant passing through the air inlet pipe 5, which causes the refrigerant to only perform heat exchange reaction on the heat exchange plate 407 in the middle, while the heat exchange efficiency of the heat exchange plates 407 on both sides is reduced, the currently discharged gas can be guided by the dispersion guide plate 903 so that the gas is diffused to both sides to avoid the gas being concentrated in the middle; The gas discharge amount also varies as needed. In order to avoid the distance between the dispersion guide plate 903 and the air inlet pipe 5 being too small when the gas discharge amount is large, thereby affecting the discharge speed, a support spring 904 is installed between the movable seat 906 and the slide rail 901. The support spring 904 of the dispersion guide plate 903 can be contracted when the gas discharge amount is too large, thereby increasing the distance and facilitating smoother gas discharge.

[0035] The working principle of the ultra-high temperature heat pump unit using a plate and shell heat exchanger with a liquid storage function: First, gaseous refrigerant is added through the air inlet pipe 5, wherein the currently discharged gas can be guided through the dispersion guide plate 903 so that the gas is diffused to both sides to avoid gas concentration in the middle.

[0036] During heat exchange, the heat exchanged fluid will enter the inlet 404 from the delivery pipe 401 under the guidance of the blocking plate 4074, 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, the gaseous refrigerant becomes liquid, and the fluid is heat exchanged. During the heat exchange process, the fluid will enter the concentration cavity 4077 through the exchange port 4075, wherein the second guide plate 4076 and the first guide plate 4073 are arranged in opposite directions, so that the fluid will be concentrated to the discharge port 403 after passing through the exchange port 4075, so that the fluid after heat exchange is transferred to the discharge port 403, and then discharged from the other end of the delivery pipe 401, thereby realizing the heat exchange operation; During the heat exchange process, the starting motor 4051 drives the transmission gear 4052 to rotate, and the transmission gear 4052 and the driven gear 406 rotate, thereby driving the tube 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, thereby 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.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
