Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat exchanger processing equipment, and more specifically to a condenser with multiple inlets and outlets. Background Technology
[0002] Currently, tube-fin condensers have been gradually upgraded from 9.52mm to 7mm to 5mm in diameter. By reducing the diameter of the copper tubes in the tube-fin evaporator, the consumption of copper and aluminum materials and the amount of refrigerant charged can be significantly reduced, thereby meeting the cost reduction needs of enterprises.
[0003] In existing condensers, there is generally one inlet and one outlet. The internal heat exchange tubes are an integral tube body with an S-shaped coil. The flow rate of refrigerant inside is limited, which leads to excessive refrigerant pressure drop, resulting in a decrease in the average temperature difference of heat exchange and a reduction in the heat exchange capacity of the evaporator.
[0004] Moreover, the outer diameter of the heat exchange tubes in existing condensers is generally 5mm or more, which still consumes a large amount of copper. In addition, in terms of heat exchange performance, the heat transfer coefficient of thin tubes is greater than that of thick tubes. Therefore, using thin tubes to make heat exchange tubes can greatly reduce costs while ensuring heat exchange effect and using less copper. However, such a structure does not exist at present. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a condenser with multiple inlets and outlets. Its heat exchanger coil assembly consists of multiple heat exchanger coils, each with an inlet and an outlet, thereby ensuring a large refrigerant flow rate and efficient heat exchange. Furthermore, the small diameter of the heat exchanger coils increases the heat transfer coefficient, while also reducing volume, weight, and cost. Additionally, the two horizontal tube sections at the leftmost end of each heat exchanger coil are aligned vertically, increasing the heat exchange area at the air inlet and improving the heat exchange effect.
[0006] The solution of this utility model to the aforementioned technical problem is: A condenser with multiple inlets and outlets includes multiple heat exchange fins and heat exchange tube coil assemblies. The transverse tube portion of the heat exchange tube coil assembly is inserted into the corresponding through holes of all the heat exchange fins. The heat exchange tube coil assembly includes at least two sets of heat exchange coils. The heat exchange coil consists of multiple horizontal tube sections and multiple U-shaped bends; Each heat exchange coil has the same length; All heat exchange coils have their inlet ends on the same side and connected to the same inlet central pipe, while all heat exchange coils have their outlet ends on the same side on the other side and connected to the same outlet central pipe. The inlet concentrator has a main inlet connector on its side wall, and the outlet concentrator has a main outlet connector on its side wall.
[0007] The heat exchanger coil assembly includes four sets of heat exchanger coils; All heat exchange coils extend laterally in an S-shape, and the four sets of heat exchange coils are evenly distributed on all heat exchange fins from top to bottom.
[0008] The first heat exchange coil is wound in the same way as the third heat exchange coil. Its structure is as follows: the tube body extends horizontally from the front end to the rear to extend the last heat exchange fin, then bends vertically upward to extend the frontmost heat exchange fin, then bends diagonally downward to the right to extend horizontally to extend the last heat exchange fin, then bends vertically downward to extend horizontally to extend the frontmost heat exchange fin, then bends diagonally upward to the right to extend horizontally to extend the last heat exchange fin, then bends vertically upward to extend horizontally to extend the last heat exchange fin, then bends vertically upward to extend horizontally to extend the last heat exchange fin, and so on, winding backward in this manner until finally extending horizontally to extend the frontmost heat exchange fin. The second heat exchange coil is wound in the same way as the fourth heat exchange coil. Its structure is as follows: the tube body extends horizontally from the front end to the rear to extend the last heat exchange fin, then bends vertically downwards and extends forward to extend the first heat exchange fin, then bends diagonally downwards to the right and extends horizontally to extend the last heat exchange fin, then bends vertically upwards and extends horizontally to extend the first heat exchange fin, then bends diagonally upwards and to the right and extends horizontally to extend the last heat exchange fin, then bends vertically downwards and extends horizontally to extend, and so on, continuing to wind backwards in this manner until finally extending horizontally to extend the first heat exchange fin.
[0009] The two transverse tube sections at the leftmost end of each heat exchange coil are aligned vertically, and the central axes of the two transverse tube sections at the leftmost end of all heat exchange coils are on the same vertical plane.
[0010] The outstanding effect of this utility model is: Compared with existing technologies, its heat exchanger coil assembly consists of multiple heat exchanger coils, each with an inlet and an outlet, resulting in a large refrigerant flow rate, reduced refrigerant pressure drop, and guaranteed heat exchange efficiency. Furthermore, the transverse tube section and U-shaped bend section of the heat exchanger coil are made of tubes with a diameter of 4mm to 4.9mm. The small tube diameter increases the heat transfer coefficient, reduces volume and weight, and lowers cost. In addition, the two transverse tube sections at the leftmost end of each heat exchanger coil are aligned vertically, thereby increasing the heat exchange area at the air inlet and improving the heat exchange effect.

Detailed Implementation
[0012] For example, see below. Figures 1 to 6 As shown, a condenser with multiple inlets and outlets includes multiple heat exchange fins 10 and heat exchange tube coil assembly 20. The transverse tube portion of the heat exchange tube coil assembly 20 is inserted into the corresponding through holes of all heat exchange fins 10. The heat exchange tube coil assembly 20 includes at least two sets of heat exchange coils 21. The heat exchange coil 21 consists of multiple horizontal tube sections and multiple U-shaped bends; Each heat exchange coil 21 has the same length; The inlet ends of all heat exchange coils 21 are on the same side and connected to the same inlet central pipe 30, and the outlet ends of all heat exchange coils 21 are on the same side on the other side and connected to the same outlet central pipe 40. The inlet concentrator 30 has a main inlet connector 31 connected to its side wall, and the outlet concentrator 40 has a main outlet connector 41 connected to its side wall.
[0013] Furthermore, the heat exchanger coil assembly 20 includes four sets of heat exchanger coils 21; All heat exchange coils 21 extend laterally in an S-shape, and the four sets of heat exchange coils 21 are evenly distributed from top to bottom on all heat exchange fins 10.
[0014] Among the four heat exchange coils 21 arranged from top to bottom, the first heat exchange coil 21 has the same winding method as the third heat exchange coil 21. Its structure is as follows: the tube body extends horizontally from the front end to the rear to extend the last heat exchange fin 10, then bends vertically upward and extends forward to extend the frontmost heat exchange fin 10, then bends diagonally downward to the right and extends horizontally to the rear to extend the last heat exchange fin 10, then bends vertically downward and extends horizontally to the frontmost heat exchange fin 10, then bends diagonally upward and to the right and extends horizontally to the rear to extend the last heat exchange fin 10, then bends vertically upward and extends horizontally to the rear, and so on, winding backward in this manner until finally extending horizontally to extend the frontmost heat exchange fin 10. The second heat exchange coil 21 is wound in the same way as the fourth heat exchange coil 21. Its structure is as follows: the tube body extends horizontally from the front end to the rear to extend the last heat exchange fin 10, then bends vertically downward and extends forward to extend the frontmost heat exchange fin 10, then bends diagonally downward to the right and extends horizontally to the rear to extend the last heat exchange fin 10, then bends vertically upward and extends horizontally to extend the frontmost heat exchange fin 10, then bends diagonally upward and to the right and extends horizontally to extend the last heat exchange fin 10, then bends vertically downward and extends horizontally to the rear, and so on, winding backward in this manner until finally extending horizontally to extend the frontmost heat exchange fin 10.
[0015] The front end of the leftmost horizontal tube section of all heat exchange coils 21 extends out of the front wall of the left side of the frontmost heat exchange fin 10 and connects to the corresponding connecting pipe connected to the side wall of the same outlet concentrator 40.
[0016] The front end of the rightmost horizontal tube section of all heat exchange coils 21 extends out of the front wall of the right side of the frontmost heat exchange fin 10 and connects to the corresponding connecting pipe connected to the side wall of the same inlet central tube 30.
[0017] In the above structure, each heat exchange coil 21 consists of 16 horizontal tubes extending forward and backward and a corresponding number of U-shaped bends. The ends of the same side between any two adjacent horizontal tubes are welded and fixedly connected through the corresponding U-shaped bends. Then, the other end of one horizontal tube is welded and fixedly connected to the end of the adjacent horizontal tube on the other side through the corresponding U-shaped bends. All the horizontal tubes and U-shaped bends are connected in this way to form an S-shaped horizontal coil.
[0018] The lengths of the connecting pipes of all outlet central pipes 40 and inlet central pipes 30 are consistent, which ensures that the refrigerant flowing in each heat exchange coil 21 has the same path and length, resulting in consistent heat exchange effect and efficiency for each heat exchange coil 21 and guaranteeing heat exchange uniformity.
[0019] Furthermore, the transverse tube section and U-shaped bend section of the heat exchange coil 21 are made of tubes with a diameter of 4mm to 4.9mm; in this embodiment, a tube with a diameter of 4mm is used. This results in a lower amount of copper used over the same length compared to existing heat exchange coils with diameters (all greater than 5mm), reducing manufacturing costs. Moreover, using 4mm copper tubes to make the heat exchange coil 21 increases the heat transfer coefficient and improves the heat exchange effect. Additionally, the small size of the 4mm diameter heat exchange coil 21 allows for the installation of four heat exchange coils 21 in this embodiment, thereby increasing the total refrigerant flow rate per unit time and improving the heat exchange effect.
[0020] Furthermore, the heat exchange coil 21 is a copper tube, and the heat exchange fins 10 are aluminum fins.
[0021] Furthermore, the front portions of the transverse tubes of all heat exchange coils 21 are fitted into the corresponding through holes of the front fixing plate 1 and welded in place, while the rear portions of the transverse tubes of all heat exchange coils 21 are fitted into the corresponding through holes of the rear fixing plate 2 and welded in place. The front ends of the transverse tubes extend beyond the front wall of the front fixing plate 1. In this embodiment, both the inlet central pipe 30 and the outlet central pipe 40 are located in front of the front fixing plate 1, making it convenient to install and connect the pipelines.
[0022] Furthermore, the two transverse tube sections at the leftmost end of each heat exchange coil 21 are aligned vertically, and the central axes of the two transverse tube sections at the leftmost end of all heat exchange coils 21 are on the same vertical plane.
[0023] This structure increases the air-facing area at the left end of each heat exchange coil 21, thereby improving its heat exchange effect and efficiency.
[0024] Finally, the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model, and the patent protection scope of the present utility model should be defined by the claims.
