[0002] The condenser is a component of the refrigeration system and a type of heat exchanger. It can convert gas or vapor into liquid and transfer the heat in the tube to the air near the tube in a very fast way. The working process of the condenser is an exothermic process, so the condenser temperature is relatively high. The condenser is mainly composed of a shell, a coil and a fan. When the refrigerant gas moves in the coil, the fan blows air to the coil to cool the refrigerant and convert the gaseous refrigerant into liquid.

[0018] The present invention provides a technical solution: an energy-saving coil mechanism for industrial air conditioning, such as Figure 1-6 As shown, it includes a support base 1, a refrigeration shell 2 and a coil 3.

When the first bevel gear 415 and the second bevel gear 417 are transmitted, the rotation angular velocity of the second rotating shaft 416 is increased. Joints 418 are installed on the upper and lower openings on the right side of the sealed shell 411. The joint 418 on the top of the left sealed shell 411 is connected to the air-conditioning return pipe to provide refrigerant to the sealed shell 411. The bottom joint 418 of the left sealed shell 411 is connected to the top joint 418 of the right sealed shell 411 through the first insulation pipe 5, and the bottom joint 418 of the right sealed shell 411 is connected to the second insulation pipe 6.

[0021] As a preferred embodiment, further, the blowing assembly 42 includes a fan shell 421 installed on the front side of the refrigeration shell 2, a mesh plate 422 is installed on the front side of the inner cavity of the fan shell 421, the mesh plate 422 is air-permeable, a hollow cylinder 423 is installed at the center of the mesh plate 422, a third rotating shaft 424 is installed at the center of the hollow cylinder 423 through a bearing, a third bevel gear 425 and a fan blade 426 are respectively installed at the front and rear ends of the third rotating shaft 424, and the third bevel gear 425 is meshed and connected with the second bevel gear 417, and the fan blade 426 can be rotated through the transmission of the second bevel gear 417 and the third bevel gear 425 to blow air to the coil 3, thereby cooling the refrigerant flowing through the coil 3.

[0023] As a preferred solution, further, the sensing component 74 includes a case 741 installed on the top of the outer wall of the conduit 73, and a Bourdon tube 742 is installed at the top opening of the conduit 73. As the refrigerant pressure increases, the Bourdon tube 742 gradually deforms. A fifth rotating shaft 743 is installed at the center of the rear side of the inner cavity of the case 741 through a bearing. A swing rod 744 and a turntable 745 are installed on the outer wall of the fifth rotating shaft 743 from front to back. The right end of the swing rod 744 is connected to the right end of the Bourdon tube 742 through a connecting rod 746. As the Bourdon tube 742 gradually deforms, the connecting rod 746 pulls the swing rod 744 to swing upward. A rack 747 meshing with the spur gear 78 is installed on the front of the rocker arm 744. The rack 747 is arc-shaped. During the swinging process of the rocker arm 744, the rack 747 always maintains stable transmission with the spur gear 78. A groove 748 is provided on the side wall of the turntable 745. A travel switch 749 electrically connected to the alarm 72 is installed on the rear side of the inner cavity of the case 741. When the turntable 745 contacts the travel switch 749, the travel switch 749 can trigger the alarm 72, indicating that the refrigerant pressure is too low. Both sides of the groove 748 are inclined surfaces, and the travel switch 749 can switch freely between the groove 748 and the side wall of the turntable 745.

[0024] Working principle: Step 1, since the first thermal insulation tube 5 connects the two sealed shells 411, the gaseous refrigerant can flow from the two sealed shells 411, and the impact force of the refrigerant drives the fan wheel 413 to rotate, and then the first rotating shaft 412 drives the first bevel gear 415 to rotate, and the angular velocity of the third bevel gear 425 is increased under the transmission of the first bevel gear 415 and the second bevel gear 417, so that the third rotating shaft 424 drives the fan blade 426 to rotate, blow air to the coil 3, increase the air flow rate around the coil 3, take away the surface heat of the coil 3, realize the cooling of the coil 3, and convert the gaseous refrigerant into liquid. Since the rotation speed of the fan wheel 413 is proportional to the refrigerant flow rate, the rotation speed of the fan blade 426 is also proportional to the refrigerant flow rate. Therefore, the power of the refrigerant flow can be used to cool the refrigerant; The cooled refrigerant is sent to the air conditioner, which then performs cooling. Step 2, when it is necessary to monitor the refrigerant pressure, the liquid refrigerant enters the Bourdon tube 742 through the conduit 73 under its own pressure. The Bourdon tube 742 can gradually deform as the pressure increases. When the pressure drops, the Bourdon tube 742 gradually returns to its original state under its own elastic conditions. Therefore, the connecting rod 746 pulls the rocker arm 744 to swing up and down, and the pointer 77 swings under the transmission of the rack 747 and the spur gear 78. The dial 75 displays the current refrigerant pressure. When the refrigerant pressure meets the refrigeration demand, the contact of the travel switch 749 is in the groove 748. Once the contact of the travel switch contacts the turntable 745, it means that the refrigerant pressure is insufficient, and the alarm 72 alarms, alerting the staff that the air conditioning refrigeration effect has deteriorated.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
