[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] Reference Figure 1 and Figure 2 The utility model discloses a high-efficiency condenser, including a tower body 100, a water circulation mechanism 600 and a heat exchanger 700. A chamber is arranged in the tower body 100, and a heat dissipation fan unit 200, an evaporative radiator 300, a condensation assembly 400 and a water collector 500 are arranged in sequence from top to bottom in the chamber.

[0036] An air outlet is provided at the top of the tower body 100 , and an air inlet is provided at the lower end of the side wall of the tower body 100 .

[0037] The heat dissipation air unit 200 is directly opposite to the air outlet. When the heat dissipation air unit 200 is working, the air outside the tower body 100 can be sucked into the chamber through the air inlet to form an airflow. The airflow will blow through the condensation component 400 and the evaporative radiator 300 in turn, and then the airflow is discharged to the outside of the tower body 100 through the air outlet.

[0038] The two ends of the condensing assembly 400 are respectively connected with a gas-phase medium inlet pipe 410 and a liquid-phase medium outlet pipe 420 , and the gas-phase medium inlet pipe 410 and the liquid-phase medium outlet pipe 420 are used to be connected to an external refrigeration mechanism to form a loop.

[0039] The water circulation mechanism 600 is used to spray the circulating condensed water in the water collector 500 onto the evaporative radiator 300 . The circulating condensed water can be poured onto the condensation assembly 400 and fall into the water collector 500 .

[0040] The heat exchanger 700 is disposed in the water collector 500. The heat exchanger 700 can be immersed in the circulating condensed water. The heat exchanger 700 is used to communicate with an external refrigeration system to form a refrigeration loop. The heat exchanger 700 is used to cool the circulating condensed water.

[0041] When the ambient temperature and humidity are low, the heat dissipation fan unit 200 is started, and the air flow blows through the condensation component 400. The air flow takes away the heat on the condensation component 400, and then cools the medium passing through the condensation component 400 to achieve air-cooled heat dissipation.

[0042] Of course, the water circulation mechanism 600 can also be started independently, and the water circulation mechanism 600 allows the circulating condensed water to be poured on the condensation component 400. The circulating condensed water takes away the heat on the condensation component 400, and then cools the medium passing through the condensation component 400, thereby realizing water-cooled coupled heat dissipation.

[0043] When the ambient temperature is high, the heat dissipation fan unit 200 and the water circulation mechanism 600 are started at the same time, and the air flow blows through the condensation component 400. The air flow takes away the heat on the condensation component 400, and then cools the medium passing through the condensation component 400. At the same time, the water circulation mechanism 600 drives the circulating condensed water to be sprinkled on the condensation component 400. The circulating condensed water takes away the heat on the condensation component 400, and then cools the medium passing through the condensation component 400, realizing air-cooling and water-cooling coupled heat dissipation, with better heat dissipation efficiency and effect.

[0044] When the airflow blows through the evaporative radiator 300, the airflow can cool the circulating condensed water, and the circulating condensed water is poured on the condensation assembly 400, and the circulating condensed water is heated. The heated circulating condensed water falls into the water collector 500, and then is drawn away by the water circulation mechanism 600 and sprayed to the evaporative radiator 300. The heated circulating condensed water is cooled in the process of falling on the evaporative radiator 300, and the cooled circulating condensed water is poured on the condensation assembly 400 again, and the above process is continuously circulated to realize uninterrupted cooling of the medium passing through the condensation assembly 400. The airflow performs a heat exchange of nearly 180° with the heated circulating condensed water in the evaporative radiator 300.

[0045] When the ambient temperature reaches the designed maximum value, the cooling fan unit 200, the water circulation mechanism 600 and the heat exchanger 700 are started at the same time. The heat exchanger 700 is connected to the external refrigeration system to form a refrigeration circuit. The refrigerant in the heat exchanger 700 absorbs the temperature of the circulating condensed water to achieve liquid cooling of the circulating condensed water. Under the joint action of the cooling fan unit 200, the evaporative radiator 300 and the heat exchanger 700, the temperature of the circulating condensed water is reduced to the required temperature requirement, realizing the coupled heat dissipation of air cooling, water cooling and liquid cooling, and achieving the best heat dissipation efficiency and effect.

[0046] Air cooling, water cooling and liquid cooling are selected according to the working environment and are applicable to various working conditions. It can avoid the heat dissipation fan unit 200 being set to too large a power and avoid excessive noise from the heat dissipation fan unit 200. Under low working environment temperature, it is only necessary to start the heat dissipation fan unit 200, which reduces power consumption and avoids wasting water resources. With the use of the water circulation mechanism 600, the heat dissipation efficiency and effect are improved, and with the use of the heat exchanger 700, it can cope with extreme high temperature conditions.

[0047] Air cooling, water cooling and liquid cooling coupled heat dissipation can ensure that the medium return temperature is no higher than 30℃.

[0048] It can be understood that the refrigeration mechanism is arranged in the intelligent computing center, and the refrigeration mechanism cools down the intelligent computing center. When the liquid medium is in the refrigeration mechanism, it absorbs the heat of the intelligent computing center, and the liquid medium changes into a gaseous medium. The gaseous medium is transported to the gaseous medium inlet pipe 410 and enters the condensation component 400. The gaseous medium releases heat in the condensation component 400 and recovers to a liquid medium. The liquid medium is transported to the refrigeration mechanism through the liquid medium outlet pipe 420. The above process is repeated continuously, and the medium is continuously converted between the gas phase and the liquid phase. The refrigeration mechanism continuously absorbs the heat of the intelligent computing center, and the condensation component 400 continuously releases the heat, thereby achieving continuous cooling of the intelligent computing center.

[0049] The components of the medium include water and substances that enhance the heat exchange of the working fluid. The substances that enhance the heat exchange of the working fluid mainly include metal nanoparticles such as iron, copper, and silver, as well as non-metallic nanoparticles or droplets such as copper oxide, titanium dioxide, aluminum oxide, and ferroferric oxide, carbon nanotubes, and corundum particles.

[0051] In another embodiment, the condensation component 400 is a serpentine coil or a folded tube, which can increase the contact area between the condensation component 400 and the circulating condensed water, thereby improving the heat exchange efficiency between the medium in the condensation component 400 and the circulating condensed water.

[0052] In some of the embodiments, the water circulation mechanism 600 includes a main pipe 610, a circulation pump 620, multiple water distribution pipes and multiple nozzles 630 arranged on the water distribution pipes, the nozzles 630 face downward and are located above the evaporative radiator 300, one end of the main pipe 610 is connected to the bottom of the water collector 500, and the multiple water distribution pipes are connected to the other end of the main pipe 610, and the circulation pump 620 is arranged on the main pipe 610.

[0053] The circulation pump 620 pumps the circulating condensed water at the bottom of the water collector 500 to each water distribution pipe through the main pipe 610, and then the circulating condensed water is sprayed toward the evaporative radiator 300 through multiple nozzles 630. The multiple nozzles 630 serve to evenly spray the circulating condensed water to various areas of the evaporative radiator 300, thereby ensuring sufficient contact and heat exchange between the airflow and the circulating condensed water.

[0054] The main pipe 610 , the circulation pump 620 and a plurality of water distribution pipes are all connected to the tower body 100 .

[0055] In some of the embodiments, the evaporative radiator 300 includes a support frame and a filler disposed on the support frame. The support frame is disposed in the chamber and connected to the tower body 100. The support frame serves to support the filler. The filler provides a larger contact surface, and the heat exchange effect is improved by circulating the contact between condensed water and air.

[0056] In some of the embodiments, an air inlet grille 800 is provided at the air inlet, and the air inlet grille 800 plays a role in filtering impurities in the air at the air inlet, thereby reducing the risk of circulating condensed water being contaminated.

[0057] In some of the embodiments, the cross-sectional shape of the tower body 100 is a regular hexagon, the number of air inlets is at least two, the two air inlets are symmetrically distributed with the tower body 100 as the center, the number of air inlet grilles 800 is equal to the number of air inlets, and the air inlet grilles 800 are arranged one-to-one with the air inlets. The air inlet grilles 800 are in the shape of a square frame, and the air inlet grilles 800 are flush with the outer wall of the tower body 100.

[0058] In another embodiment, the cross-sectional shape of the tower body 100 is circular, and the shape of the air inlet grille 800 is arc-shaped, so that the shapes of the air inlet grille 800 and the tower body 100 are matched with each other.

[0059] In some of the embodiments, the heat exchanger 700 is a coil structure or a bent pipe structure, so that the contact area between the heat exchanger 700 and the circulating condensed water is increased within a limited volume.

[0060] In some of the embodiments, the bottom surface of the tower body 100 is connected to a horizontal adjustment base 900, and the tower body 100 is set on the ground, roof or platform through the horizontal adjustment base 900.

[0062] The pipeline is provided with a solenoid valve 440, which serves to cut off the pipeline. When the solenoid valve 440 is closed, the leakage rate meets the requirement of establishing a balanced working condition between the condensing assembly 400 and the refrigeration mechanism system. The solenoid valve 440 can be controlled by a remote switch.

[0063] The condensing assembly 400 or the gas phase medium inlet pipe 410 is connected to a pressure sensor 450 through a pipeline. The pressure change inside the condensing assembly 400 can be known in real time, and the condensing assembly 400 and the refrigeration mechanism system have the function of maintaining the balanced working condition.

[0064] The vacuum pump 430 has a non-grease lubrication or oil overflow prevention function to avoid contamination of the condensing assembly 400 and the internal channels of the refrigeration mechanism system.
