Technical Field

[0001] The invention relates to the technical field of air coolers, in particular to an elliptical tube air cooler of a high-efficiency air cooler. Background Art

[0002] Air drying systems are widely used in industry, and are commonly used as protective gas or diluent gas in oil and gas transportation, power, chemical and other industries. Air drying systems are mainly composed of Roots blowers or air compressors, air coolers, adsorption air dryers, and pre- and post-filters.

[0003] The existing coolers have low heat exchange efficiency, poor separation effect and complex structure. CN217988883U discloses a cooler in an air drying system, in which the finned tubes are spiral finned tubes and are densely arranged, with a small heat exchange area, and the air and the finned tubes cannot exchange heat efficiently, which leads to poor heat exchange efficiency between the finned tubes and the air in the patent. Summary of the invention

[0004] The object of the present invention is to provide a high-efficiency air cooler elliptical tube air cooler, which effectively increases the heat exchange area of ​​the air cooler through a special refrigeration coil structure and arrangement, thereby improving the refrigeration capacity of the air cooler.

[0005] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme: The present invention provides a high-efficiency air cooler elliptical tube cold air blower, which comprises an axial flow fan, a fan fixing frame, an elliptical refrigeration coil and a casing, wherein a water distribution screen and a water receiving tray are further arranged in the casing, wherein the axial flow fan is fixedly assembled in front of the casing and is used to blow airflow into the casing in a positive direction, wherein the elliptical refrigeration coil passes through the casing along the length direction of the casing, and the long axis direction of the cross-section ellipse of the elliptical refrigeration coil is arranged parallel to the airflow blowing direction of the axial flow fan; The elliptical refrigeration coils in the same vertical plane perpendicular to the airflow blowing direction are called elliptical refrigeration coils in the same row. Multiple rows of interconnected elliptical refrigeration coils are arranged at equal intervals in the casing, and the elliptical refrigeration coils in adjacent rows are staggered in space. Fixed heat sinks are arranged at equal intervals in the casing perpendicular to the length direction of the elliptical refrigeration coils, and the fixed heat sinks are used to support the elliptical refrigeration coils.

[0006] As a preferred technical solution of the present invention, the casing is provided with the water distribution screen and the defrosting water inlet above the elliptical refrigeration coil.

[0007] As a preferred technical solution of the present invention, one end of one or more rows of elliptical refrigeration coils close to the axial flow fan is connected to a liquid separator plate to introduce refrigerant liquid, and the liquid separator plate is connected to a refrigerant liquid inlet.

[0008] As a preferred technical solution of the present invention, a row of elliptical refrigeration coils away from the axial flow fan are connected to a vertically arranged header, and a refrigerant gas outlet is arranged at the bottom of the header.

[0009] As a preferred technical solution of the present invention, a pair of axial flow fans are provided to synchronously and positively blow air into the casing.

[0010] As a preferred technical solution of the present invention, the water receiving tray having an inverted cone structure is fixed below the casing, and a drain outlet is provided at the bottom of the inverted cone structure of the water receiving tray.

[0011] As a preferred technical solution of the present invention, hanging holes are provided at the upper corners of the casing.

[0012] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects: In the present invention, the refrigerant liquid enters the liquid distribution plate from the refrigerant liquid inlet, and is distributed into the elliptical refrigeration coil by the liquid distribution plate. When the axial flow fan blows the airflow into the casing, the heat carried by the airflow will produce heat exchange with the elliptical refrigeration coil in the casing, and from near to far, after heat exchange with a row of elliptical refrigeration coils close to the axial flow fan, the specific elliptical shape of the coil will block the airflow into the upper and lower parts of the elliptical tube and then flow to the coil far behind. Since the adjacent rows of coils are staggered, the airflows disturb each other and further divert, so that the blown airflow forms turbulence to improve the heat exchange efficiency; at the same time, the elliptical shape of the elliptical refrigeration coil in the present invention is also conducive to increasing the heat exchange area compared to the circular coil. Therefore, the present invention is conducive to improving the refrigeration capacity of the air cooler. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figures 1 to 4 As shown, a high-efficiency air cooler elliptical tube cold air blower comprises an axial flow fan 100, a fan fixing frame 200, an elliptical refrigeration coil 300 and a casing 400, wherein the casing 400 is further provided with a water distribution screen 500 and a water receiving tray 600, wherein the axial flow fan 100 is fixedly mounted in front of the casing 400 and is used to blow airflow into the casing 400 in a positive direction, wherein the elliptical refrigeration coil 300 passes through the casing 400 along the length direction of the casing 400, and the long axis direction of the cross-section ellipse of the elliptical refrigeration coil 300 is arranged parallel to the airflow blowing direction of the axial flow fan 100; The elliptical refrigeration coils 300 in the same vertical plane perpendicular to the airflow blowing direction are defined as elliptical refrigeration coils in the same row. Multiple rows of interconnected elliptical refrigeration coils 300 are evenly spaced in the casing 400, and the elliptical refrigeration coils 300 in adjacent rows are staggered in space. Fixed heat sinks 700 are evenly spaced in the casing 400 perpendicular to the length direction of the elliptical refrigeration coils 300, and the fixed heat sinks 700 are used to support the elliptical refrigeration coils 300.

[0025] Based on the structure and arrangement of the above-mentioned specific elliptical refrigeration coil 300, after the airflow blown by the axial flow fan 100 enters the casing 400, it will first exchange heat with a row of elliptical refrigeration coils 300 close to the axial flow fan 100. The cross-section of the refrigeration coil in the present invention is elliptical. After a special staggered arrangement, the heat exchange area with the airflow is larger, which is beneficial to improving the overall heat exchange efficiency and the cooling capacity of the air cooler; secondly, the refrigeration coil can disrupt the airflow passing through it, and disturb each other to form turbulence, so as to improve the heat exchange efficiency between the airflow and the refrigeration coil, and further enhance the cooling capacity of the air cooler.

[0026] Furthermore, in order to facilitate defrosting of the device, the housing 400 is provided with the water distribution screen 500 and the defrosting water inlet 510 above the elliptical refrigeration coil 300 .

[0027] It can be imagined that by flowing the refrigerant liquid from a position close to the axial flow fan 100 to a position far away from the axial flow fan 100, the refrigerant liquid can more fully exchange heat with the airflow blown by the axial flow fan 100. Therefore, in some embodiments, the refrigerant liquid is introduced into one end of one or more rows of elliptical refrigeration coils 300 close to the axial flow fan 100 through a connecting separator plate 310, and the separator plate 310 is connected to a refrigerant liquid inlet 320.

[0028] Furthermore, a row of elliptical refrigeration coils 300 away from the axial flow fan 100 are connected to a vertically arranged header 330 , and a refrigerant gas outlet 340 is arranged at the bottom of the header 330 .

[0029] In the present invention, a pair of axial flow fans 100 are provided to synchronously and positively blow air into the casing 400 .

[0030] In order to receive condensed water and defrosting water, the water receiving tray 600 having an inverted cone structure is fixed below the housing 400 , and a drain port 610 is provided at the bottom of the inverted cone structure of the water receiving tray 600 .

[0031] In order to facilitate the overall transportation of the device, in the present invention, a hanging hole 410 is provided at the upper corner of the housing 400 .

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
