This requires a large amount of power to allow cold air from outside the tower to enter and exchange heat with the hot fluid in the packing zone. Common problems include high power consumption of water pumps and fans, inconvenient maintenance, low air intake efficiency, and high noise. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1-2 This utility model provides an air-cooled phase change condenser, comprising:

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

[0032] A hot steam inlet mechanism is located inside the housing 900;

[0033] A gas source is used to supply hot steam into the hot steam inlet mechanism.

[0034] The heat exchange mechanism is located inside the shell 900 and is connected to the hot steam inlet mechanism.

[0035] A blower 300 is mounted on the housing 900, with its output end facing the heat exchange mechanism.

[0036] The hot steam inlet mechanism, heat exchange mechanism, and condensate outlet 510 are arranged in descending order of height.

[0037] The heat exchange mechanism and the blower 300 work together to convert the hot steam introduced by the hot steam inlet mechanism into a liquid cooling medium and efficiently transfer heat in the shell 900. The hot steam inlet mechanism, the heat exchange mechanism and the condensate outlet 510 are arranged in descending order of height to achieve automatic reflux under gravity drive. The heat exchange process in the shell 900 does not require any energy assistance, which significantly reduces the energy consumption of the condenser system.

[0038] Furthermore, hot steam includes water vapor, ammonia vapor, acetone vapor, or vaporized high-enthalpy chlorofluorocarbons, etc.

[0039] In one embodiment of this utility model, the hot steam inlet mechanism includes:

[0040] Several hot steam pipes 110 are disposed inside the housing 900. The hot steam pipes 110 are connected to the heat exchange mechanism. One end of the hot steam pipe 110 is provided with a hot steam inlet 100 for connection to the gas source. A pressure monitoring sensor 400 is disposed inside the hot steam pipe 110.

[0041] In one embodiment of this utility model, the heat exchange mechanism includes:

[0042] Several condenser tubes 200 are installed inside the housing 900. The several condenser tubes 200 correspond one-to-one with several hot steam main pipes 110 and are connected. The end of the condenser tube 200 away from the hot steam main pipe 110 is open and faces the condensate outlet 510.

[0043] The gas source is supplied by delivering the hot steam vaporized by the evaporator to the outdoor condenser through the saturated steam pressure difference or other micro-power auxiliary devices. The hot steam enters the hot steam main pipe 110 through the hot steam inlet 100 and is then supplied to the condenser tube 200. The condenser tube 200 is subcooled and condenses into film or beads. After condensation, the liquid medium flows down the inner wall of the tube under the action of gravity or the gravitational component, and at the same time, it disturbs the surrounding liquid medium, causing droplets to fall off over a larger area, thus accelerating the condensation heat exchange effect.

[0044] Furthermore, the condenser tube 200 is made of a high thermal conductivity material (such as copper or 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 pipe 110. By acquiring the measurement parameters, the pressure distribution inside the hot steam pipe 110 can be adjusted accordingly. 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 this utility model, a plurality of condenser tubes 200 are arranged vertically or inclined along the vertical height direction of the housing 900. When the condenser tubes 200 are inclined, the angle between the inclination angle and the vertical height direction of the housing 900 is less than 75 degrees.

[0047] In one embodiment of this utility model, a condensate recovery device 500 is provided at the condensate outlet 510, which also serves as a vapor-liquid medium separation device. It utilizes the gravitational field and density difference to efficiently separate the vapor-liquid working fluid without consuming any energy.

[0048] In one embodiment of this utility model, the condenser tube 200 has a finned structure to increase its equivalent heat dissipation area, and the tubes are arranged in a staggered manner.

[0049] In one embodiment of this utility model, the blower 300 is a variable frequency fan. The variable frequency fan drives the lower temperature air 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 change and the temperature of the vertical finned condenser tube 200.

[0050] In one embodiment of this utility model, a liquid level monitoring sensor 600 is provided at the bottom of the housing 900 to monitor the vapor-liquid interface and measure the volume of the liquid working fluid.

[0051] In one embodiment of this utility model, 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 liquid mass flowing out of the condensate outlet 510 in real time and provides feedback on the adjustment parameters.

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

[0053] In one embodiment of this utility model, a backup cold source refrigerator 800 and a backup cold source heat exchanger 700 connected to the backup cold source refrigerator 800 are also included. The backup cold source heat exchanger 700 is connected to the condensate outlet 510. In high temperature and high humidity environments, the liquid reflux medium is cooled by turning on the backup cold source refrigerator 800 to meet the requirements of uninterrupted use.

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
