Description

Technical Field

[0001] The present application relates to the field of air handling systems, and in particular to a surface cooler and an air handling device. Background Art

[0002] Surface cooler, also called surface air cooler, mainly regulates air temperature and humidity by using refrigerant water for heat and mass exchange.

[0003] In the production of clean rooms, there are strict requirements for temperature and humidity control of the environment. In the summer environment, the air contains a large amount of moisture, which needs to be condensed and removed by the surface cooler. During the dehumidification process of the existing surface cooler, the moisture in the air condenses on the fins of the surface cooler and cannot flow down in time. It is continued to be dried and evaporated by the fresh air, resulting in poor dehumidification effect in the clean room. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a surface cooler and an air treatment device, which can reduce the amount of condensed water that is not dried and volatilized by the wind in the air duct and sent to the next device due to untimely flow, thereby effectively improving the dehumidification effect.

[0011] In a possible implementation manner, the orthographic projection of the drainage hole on the first tube wall is arranged offset from the collecting hole.

[0012] In the above implementation process, the staggered arrangement is used to avoid excessive loss of wind pressure in the air duct, which would affect the air supply function of the air duct.

[0013] In a possible embodiment, the number of the drainage holes is less than the number of the collecting holes, and the number of the drainage holes is 1-3.

[0014] In the above implementation process, the number of drainage holes is smaller than the number of collection holes and the number of drainage holes is 1-3, so as to avoid excessive loss of wind pressure and affect the air supply function of the air duct.

[0016] In the above implementation process, the setting method of the collection holes is beneficial to quickly collect condensed water into the collection chamber under the action of centrifugal force and the wind pressure in the air duct, reducing the residence time of condensed water in the first tube wall, and helping to reduce the amount of condensed water that is dried and volatilized by the wind in the air duct and sent to the next device due to untimely flow, thereby effectively improving the dehumidification effect.

[0017] In a possible implementation, a plurality of collection hole groups are arranged at equal intervals along the axial direction of the air duct, and / or, in each collection hole group, a plurality of collection holes are arranged at equal intervals along the circumference of the first tube wall.

[0018] In the above implementation process, the equidistant arrangement is beneficial to uniform force on all parts of the surface cooler, improving the service life, and further reducing the amount of condensed water that is evaporated by the wind in the air duct and sent to the next device due to untimely flow, effectively improving the dehumidification effect.

[0019] In a possible implementation manner, the surface cooler further includes a driving assembly, which is drivingly connected to the rotating shaft to drive the rotating shaft to rotate.

[0020] In the above implementation process, the setting of the driving component is conducive to the automation and precision operation of the surface cooler, reducing labor costs.

[0021] In a possible implementation, the air duct has an air inlet end and an air outlet end relative to each other along its axial direction, the driving assembly is arranged at the air outlet end, and a rotating joint for an external device is provided at one end of the rotating shaft located at the air inlet end.

[0036] The present application provides an air treatment device, wherein the air treatment component comprises a fan and a surface cooler, and the fan is used to supply air to the surface cooler.

[0037] It should be noted that the air handling components include but are not limited to fans and surface coolers. In addition, other components can be selected according to actual needs and are not limited here.

[0038] like Figure 1 as well as Figure 2 As shown, the surface cooler 1000 includes an air duct 11 for supplying air and a rotating assembly 12 located in the air duct 11 .

[0039] Among them, the rotating component 12 includes a rotating shaft 121, a plurality of fins 122 and a condenser 123. The axial direction of the rotating shaft 121 is parallel to the axial direction of the air duct 11. The plurality of fins 122 are spaced apart and distributed circumferentially of the rotating shaft 121. The condenser 123 is penetrated through the plurality of fins 122 to cool each fin 122. The rotating shaft 121 can be rotatably installed in the air duct 11 to drive the fins 122 and the condenser 123 to rotate synchronously.

[0040] The air duct 11 is provided with a drainage hole 114 , and the drainage hole 114 is located below the rotating assembly 12 .

[0041] It is understandable that the air duct 11 is usually arranged horizontally along its axial direction, and the drainage hole 114 is located below the rotating component 12, which means that the drainage hole 114 is located below the rotating component 12 in the gravity direction, that is, the drainage hole 114 is opened on the side wall of the air duct 11.

[0042] The surface cooler 1000 provided in the present application supplies air, and utilizes a rotating shaft 121 that is rotatably installed in the air duct 11 to drive the fins 122 and the condenser 123 to rotate synchronously. The condensed water on the fins 122 is removed by centrifugal force, and the drain hole 114 is located below the rotating component 12, which is beneficial for the condensed water to be discharged from the surface cooler 1000 from the drain hole 114 under the action of gravity, and is beneficial for reducing the amount of condensed water that is not dried up and volatilized by the wind in the air duct 11 and sent to the next device due to the untimely flow of condensed water, thereby effectively improving the dehumidification effect.

[0043] The rotating unit is located in the air duct 11 and can rotate in the air duct 11. The rotating unit can be supported by an external supporting device and has no actual connection with the air duct 11. It can also be connected to the air duct 11 through a bracket (not shown).

[0044] In order to improve the stability of the surface cooler 1000, in this embodiment, the air duct 11 is provided with a bracket, and the rotating shaft 121 is rotatably mounted on the bracket.

[0045] The air duct 11 may be single-layered, that is, the air duct 11 is not provided with an interlayer.

[0046] See also Figure 1 as well as Figure 2 The air duct 11 includes a first tube wall 111 and a second tube wall 112. The second tube wall 112 is sleeved on the circumference of the first tube wall 111 and forms a collecting cavity with the first tube wall 111. The first tube wall 111 is provided with a plurality of collecting holes 113 connected to the collecting cavity, and a drainage hole 114 is opened in the second tube wall 112.

[0047] That is, the first tube wall 111 is located on the inner side of the second tube wall 112 and a sandwich as a collecting chamber is formed between the two. With the setting of the collecting chamber, condensed water can be quickly collected into the collecting chamber under the action of centrifugal force and the wind pressure in the air duct 11, reducing the residence time of condensed water in the first tube wall 111, which is conducive to reducing the amount of condensed water that is dried and volatilized by the wind in the air duct 11 and sent to the next device due to untimely flow of condensed water, thereby effectively improving the dehumidification effect.

[0048] The first tube wall 111 and the second tube wall 112 are coaxially arranged, and the materials of the first tube wall 111 and the second tube wall 112 can be the same, which is not limited here.

[0049] The orthographic projection of the drainage hole 114 on the first tube wall 111 may correspond to or be offset from the collecting hole 113. In order to avoid excessive loss of wind pressure in the air duct 11 and affect the air supply function of the air duct 11, in this embodiment, the orthographic projection of the drainage hole 114 on the first tube wall 111 is offset from the collecting hole 113.

[0050] The number of the drainage holes 114 is at least one. In order to avoid excessive loss of wind pressure and affect the air supply function of the air duct 11, the number of the drainage holes 114 is less than the number of the collecting holes 113, and the number of the drainage holes 114 is 1-3.

[0051] Exemplarily, the number of the drainage holes 114 is 1, 2 or 3.

[0052] like Figure 2 As shown, the number of the drainage hole 114 is one.

[0053] The number of the collecting holes 113 is multiple, where multiple means two or more, such as two, ten, twenty, and so on.

[0054] like Figure 1 as well as Figure 2 As shown, the first tube wall 111 is provided with a plurality of collection hole 113 groups, and the plurality of collection hole 113 groups are arranged at intervals along the axial direction of the air duct 11 , and each collection hole 113 group includes a plurality of collection holes 113 arranged at intervals along the circumferential direction of the first tube wall 111 .

[0055] The setting method of the collection hole 113 is beneficial for quickly collecting condensed water into the collection chamber under the action of centrifugal force and the wind pressure in the air duct 11, reducing the residence time of the condensed water in the first tube wall 111, and helping to reduce the amount of condensed water that is not dried and volatilized by the wind in the air duct 11 and sent to the next device due to the untimely flow, thereby effectively improving the dehumidification effect.

[0056] The plurality of collection holes 113 groups are arranged at equal intervals along the axial direction of the air duct 11 , and / or, in each collection hole 113 group, the plurality of collection holes 113 are arranged at equal intervals along the circumference of the first tube wall 111 .

[0057] In the above implementation process, the equidistant arrangement is beneficial to uniform force on all parts of the surface cooler 1000, thereby improving the service life, and is beneficial to further reduce the amount of condensed water that is not dried and volatilized by the wind in the air duct 11 and sent to the next device due to untimely flow, thereby effectively improving the dehumidification effect.

[0058] like Figure 1 as well as Figure 2 As shown, a plurality of collection hole 113 groups are arranged at equal intervals along the axial direction of the air duct 11 , and in each collection hole 113 group, a plurality of collection holes 113 are arranged at equal intervals along the circumference of the first tube wall 111 .

[0059] The fins 122 are used to exchange heat with the condenser tube 123 to reduce the temperature of the fins 122 to adjust the air temperature.

[0060] In order to improve the cooling effect, the fins 122 are metal fins 122 , and illustratively, the fins 122 are aluminum fins 122 .

[0061] In order to improve the cooling effect, a plurality of fins 122 are distributed at equal intervals in the circumferential direction of the rotating shaft 121 , and each fin 122 extends along the axial direction of the rotating shaft 121 .

[0062] The condenser tube 123 is filled with cold water. In order to improve the service life and cooling effect of the condenser tube 123, the condenser tube 123 is a copper tube.

[0063] The condenser 123 may be arranged in an axial spiral along the rotating shaft 121 , or in a circumferential spiral along the rotating shaft 121 , or may be in a ring shape, etc.

[0064] like Figure 1 as well as Figure 2 As shown, the condenser tube 123 is spirally arranged along the axial direction of the rotating shaft 121 .

[0065] The above arrangement has a good cooling effect on the one hand, and on the other hand, it is convenient to smoothly throw the condensed water on the fins 122 onto the air duct 11 under the action of centrifugal force, which is beneficial for the condensed water to be discharged from the surface cooler 1000 from the drain hole 114 under the action of gravity.

[0066] The number of the condenser 123 is one or more. Figure 1 as well as Figure 2The number of the condenser tube 123 is one, and the condenser tube 123 is wound so that it is not only arranged in an axial spiral along the rotating shaft 121, but also arranged in a circumferential spiral along the rotating shaft 121, which effectively increases the contact area between the condenser tube 123 and the fin 122 and improves the cooling effect.

[0067] like Figure 2 As shown, the surface cooler 1000 further includes a driving assembly 13, which is in transmission connection with the rotating shaft 121 to drive the rotating shaft 121 to rotate.

[0068] In the above implementation process, the setting of the driving component 13 is conducive to the automatic and precise operation of the surface cooler 1000, thereby reducing labor costs.

[0069] The driving component 13 is, for example, a servo motor, wherein the servo motor is coaxially connected to the rotating shaft 121. In order to reduce the occupied space and improve the operating stability, the base of the servo motor is installed on the bearing seat, and the relative position of the bearing seat and the air duct 11 remains fixed, that is, at this time the bearing seat can be installed on the air duct 11 or fixed to the ground, etc.

[0070] like Figure 1 as well as Figure 2 As shown, the air duct 11 has an air inlet end 115 and an air outlet end 116 opposite to each other along its axial direction, the driving assembly 13 is disposed at the air outlet end 116, and a rotating joint for an external device is disposed at one end of the rotating shaft 121 located at the air inlet end 115.

[0071] The surface cooler and air handling device provided in the present application can remove condensed water on the fins by centrifugal force, and the condensed water can be discharged from the surface cooler from the drain hole under the action of gravity, which is beneficial to reduce the amount of condensed water that is dried and volatilized by the wind in the air duct and sent to the next device due to untimely flow, thereby effectively improving the dehumidification effect.

[0072] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
