DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in 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 creative work are within the scope of protection of the present invention.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figure 1-Figure 2 The present invention provides an air-cooled phase-change condenser, comprising:

[0031] The housing 900 is a conical structure, and a condensate outlet 510 is provided at the small diameter end of the housing 900;

[0032] A hot steam intake mechanism is disposed in the housing 900;

[0033] An air source, used for supplying hot steam into the hot steam intake mechanism;

[0034] The heat exchange mechanism is disposed in the housing 900 and is connected to the hot steam intake mechanism;

[0035] The air blowing device 300 is disposed on the housing 900, and the output end of the air blowing device 300 faces the heat exchange mechanism;

[0036] The hot steam intake mechanism, the heat exchange mechanism and the condensate outlet 510 are arranged in sequence from high to low.

[0037] The heat exchange mechanism and the blowing device 300 cooperate with each other in the shell 900 to convert the hot steam introduced by the hot steam intake mechanism into a vapor cooling medium and transfer the heat efficiently. The hot steam intake mechanism, the heat exchange mechanism and the condensate outlet 510 are arranged in sequence from high to low to achieve automatic reflux driven by gravity. The process of heat exchange in the shell 900 does not require any energy assistance, which significantly reduces the energy consumption index of the condenser system.

[0038] Furthermore, the hot steam includes water vapor, ammonia vapor, acetone vapor or vapor-state high enthalpy chlorofluorocarbons and the like.

[0039] In one embodiment of the present invention, the hot steam intake mechanism comprises:

[0040] A plurality of hot steam main pipes 110 are arranged in the shell 900 . The hot steam main pipes 110 are connected to the heat exchange mechanism. A hot steam inlet 100 for connecting to the gas source is arranged at one end of the hot steam main pipe 110 . A pressure monitoring sensor 400 is arranged in the hot steam main pipe 110 .

[0041] In one embodiment of the present invention, the heat exchange mechanism comprises:

[0042] A plurality of condensing tubes 200 are disposed in the shell 900 . The plurality of condensing tubes 200 correspond to and are connected with a plurality of hot steam main pipes 110 . One end of the condensing tube 200 away from the hot steam main pipe 110 is open and faces the condensate outlet 510 .

[0043] The air source is supplied in a manner that the hot steam vaporized by the evaporator is transported to the outdoor condenser through the hot steam inlet 100 or other micro-power auxiliary devices, and then enters the hot steam main pipe 110, and is then supplied to the condenser 200 through the hot steam main pipe 110. The air is supercooled in the vertical condenser 200 to form a film or bead condensation. After condensation, the liquid medium flows downward along the inner wall of the tube under the action of gravity or gravity component, and at the same time, the surrounding liquid medium is disturbed, causing droplets to fall off in a larger range, thereby accelerating the condensation heat exchange effect.

[0044] Furthermore, the condenser tube 200 is made of a high thermal conductivity material (such as copper, stainless steel), and a hydrophobic layer is provided on the inner wall of the condenser tube 200 to further enhance the condensation heat exchange effect.

[0045] The pressure monitoring sensor 400 monitors the thermal state inside the hot steam main pipe 110. By obtaining the measurement parameters, the pressure distribution inside the hot steam main pipe 110 can be adjusted. The range of the pressure monitoring sensor 400 should be maintained between -0.1MPa and +0.1MPa, and the measurement accuracy should not be less than 0.1Pa.

[0046] In one embodiment of the present invention, a plurality of condensers 200 are arranged vertically or inclined along the vertical height direction of the shell 900. When the condenser 200 is inclined, the angle between the inclination angle and the vertical height direction of the shell 900 is less than seventy-five degrees.

[0047] In one embodiment of the present invention, a condensate recovery device 500 is provided at the condensate outlet 510, which has the function of separating vapor and liquid media, and utilizes the gravity field and density difference to efficiently separate the vapor and liquid working medium without consuming any energy assistance.

[0048] In one embodiment of the present invention, the condenser tube 200 is a fin structure to increase its equivalent heat dissipation area, and the tube rows are arranged in a staggered manner.

[0049] In one embodiment of the present invention, the blowing device 300 is a variable frequency fan, which drives the air with lower temperature to blow the condenser tube 200 array to complete the system-level heat exchange. The variable frequency fan can control the speed and air volume according to the load changes and the temperature of the vertical fin condenser tube 200.

[0050] In one embodiment of the present invention, a liquid level monitoring sensor 600 is disposed at the bottom of the shell 900 to monitor the vapor-liquid interface and measure the volume of the liquid working fluid.

[0051] In one embodiment of the present invention, a flow sensor 520 is provided at the condensate outlet 510. The flow sensor 520 is an ultrasonic flow sensor. The flow sensor 520 measures the mass of the liquid flowing out of the condensate outlet 510 in real time and feeds back adjustment parameters.

[0052] Furthermore, temperature sensors are arranged along the heat dissipation path in the housing 900 to measure and evaluate the overall temperature level and changes.

[0053] In one embodiment of the present invention, a standby cold source refrigerator 800 and a standby cold source heat exchanger 700 connected to the standby cold source refrigerator 800 are also included. The standby cold source heat exchanger 700 is connected to the condensate outlet 510. When the high temperature and high humidity environment is reached, the liquid reflux medium is cooled by turning on the standby cold source refrigerator 800 to meet the requirement of uninterrupted use.

[0055] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
