DETAILED DESCRIPTION

[0056] The following will be combined with the attached embodiment of the present invention Figure 1-Figure 9 , clearly and completely describe the technical solutions in the embodiments of the present invention. The present invention can be implemented in many different forms and is not limited to the implementation methods described in this embodiment. The purpose of providing the following specific implementation methods is to facilitate a clearer and more thorough understanding of the disclosure of the present invention, wherein the words indicating directions such as below refer only to the position of the structure shown in the corresponding drawings.

[0057] It is understood that the terms used herein are only for describing specific embodiments and are not intended to limit the present invention. When used herein, the singular forms "a" and "" are also intended to include the plural forms unless the context clearly states otherwise. Further, when used in this specification, the terms "include" and / or "comprise" indicate the presence of features, wholes, steps, elements and / or components, but do not exclude the presence or increase of one or more other features, wholes, steps, elements, components and / or combinations thereof. The subsequent description of the specification is a preferred embodiment of the present invention, but the description is for the purpose of illustrating the general principles of the present invention and is not intended to limit the scope of the present invention. The scope of protection of the present invention shall be determined by the appended claims.

[0058] like Figure 1-Figure 7 As shown, the present invention provides a condenser heat exchange device 100, which is applied to an evaporative cooler unit 1000 and can switch between a spray mode and a mist mode according to the ambient temperature and / or the condensation temperature to save water.

[0059] Specifically, the condenser heat exchange device 100 includes a water supply component 101 and a spray spray switching component 102. The outlet of the water supply component 101 extends into the shell 200 of the evaporative cooler unit 1000 to provide sufficient water to the spray spray switching component 102.

[0060] The water supply component 101 can be directly connected to an external water source, or the cooling water collected in the cooling water recovery device in the evaporative cooler unit 1000 can be used as a water source to recycle the cooling water and further save water. Of course, it is also possible to simultaneously connect an external water source and use the cooling water collected in the cooling water recovery device. When the cooling water in the cooling water recovery device is insufficient, the external water source is used for water supply. The water supply component 101 includes a water pump and a connecting pipeline. The inlet of the water pump is connected to the water source, and the outlet of the water pump is connected to the connecting pipeline, and the connecting pipeline extends into the housing 200.

[0061] The spray spray switching component 102 is located in the housing 200 , and the inlet of the spray spray switching component 102 is connected to the outlet of the water supply component 101 .

[0062] When the ambient temperature is greater than the first ambient preset temperature and / or the condensation temperature of the condenser 300 in the evaporative cooler unit is greater than the first condenser preset temperature, the spray spray switching component 102 switches to the spray mode to spray the condenser 300 in the evaporative cooler unit 1000, using a large amount of water to increase the phase change of the spraying liquid and quickly reduce the temperature of the condenser 300.

[0063] When the ambient temperature is less than or equal to the first ambient preset temperature, and / or the condensation temperature of the condenser 300 is less than or equal to the first condenser preset temperature, the spray spray switching component 102 switches to the spray mode and sprays mist to the condenser 300, thereby satisfying the phase change heat transfer effect and reducing water consumption, thereby saving water.

[0064] In the present invention, the ambient temperature or the condensing temperature of the condenser 300 can be used alone to control the switching of the spray spray switching component 102. Of course, the ambient temperature and the condensing temperature of the condenser 300 can also be used simultaneously to control the switching of the spray spray switching component 102.

[0065] It should be noted that the condensing temperature of the condenser 300 is not limited to the temperature inside the condenser. For the convenience of detection, the surface temperature of the condenser 300 can be used as the condensing temperature of the condenser.

[0066] In summary, the present invention switches the spraying or spraying to the condenser 300 to cool down according to the external environment temperature and / or the condensation temperature, thereby reducing the water consumption and saving water.

[0067] In order to further save water, the present invention discloses that when the ambient temperature is lower than the second ambient preset temperature, and / or the condensing temperature of the condenser 300 is lower than the second condenser preset temperature, the water supply component 101 is closed, the spray spray switching component 102 stops working, and the heat exchange cooling of the condenser 300 is realized by the air cooling mode. It can be understood that the spray spray switching component 102 stops working here means that the spray spray switching component 102 stops spraying and spraying.

[0068] The condensation temperature of the condenser 300 is higher than the ambient temperature, the first ambient preset temperature is higher than the second ambient preset temperature, the first condenser preset temperature is higher than the second condenser preset temperature, and the specific temperature values ​​are set as needed.

[0069] Furthermore, the present invention discloses that the condenser heat exchange device 100 further includes a controller, an ambient temperature sensor and / or a condenser temperature sensor, the ambient temperature sensor is used to detect the ambient temperature, and the condenser temperature sensor is used to detect the condensation temperature of the condenser 300. Specifically, the installation positions of the controller and the ambient temperature sensor are not limited, and they can be installed on the housing 200, or a separate installation platform can be provided to install the controller and the ambient temperature sensor, etc.

[0070] The controller is respectively connected to the spray spray switching component 102, the water supply component 101, the ambient temperature sensor and / or the condenser temperature sensor signal.

[0071] The controller controls the start and stop of the water supply component 101 according to the ambient temperature sensor and / or the detected temperature value, and controls the spray spray switching component 102 to switch to the spray mode or the spray mode, thereby realizing automatic conversion of the various modes of the spray spray switching component 102, which is convenient and fast.

[0072] In some embodiments, the condenser heat exchange device 100 also includes a fan, which is installed on the shell 200 and is used to drive the mist sprayed by the spray spray switching assembly 102 located on the air flow path of the fan to flow through the condenser 300. When the ambient temperature is lower than the second ambient preset temperature, and / or the condensation temperature of the condenser 300 is lower than the second condenser preset temperature, the fan can also blow cold air to the condenser 300 to air-cool the condenser 300.

[0073] It should be noted that the spray spray switching assembly 102 is located at least on one of the top, bottom and side of the condenser 300, that is, the spray spray switching assembly 102 can be installed only on the top, bottom or side of the condenser 300; the spray spray switching assembly 102 can also be installed on the top and bottom of the condenser 300 at the same time, or, installed on the top and side of the condenser 300 at the same time, or, installed on the bottom and side of the condenser 300 at the same time; the spray spray switching assembly 102 can also be installed on the top, bottom and side of the condenser 300 at the same time to improve the efficiency of cooling the condenser 300.

[0074] In some embodiments, the shower spray switching assembly 102 includes a lifting assembly 102a and a lifting baffle 102b.

[0075] The lifting baffle 102 b is connected to the driving end of the lifting assembly 102 a , and the fixed end of the lifting assembly 102 a is connected to the housing 200 .

[0076] The lifting component 102a drives the lifting baffle 102b to move closer to or away from the outlet of the water supply component 101, and the position movement of the spray switching component 102 is achieved through the lifting component 102a.

[0077] The lifting baffle 102b is first at a relatively large distance from the outlet of the water supply component 101. At this time, the sprayed droplets are slightly reduced. When the lifting baffle 102b moves closer to the outlet of the water supply component 101, the droplets become smaller and smaller due to the greater impact force, and finally form small mist-like particles.

[0078] It should be noted that a plurality of spray heads 102c - 1 may also be installed at the outlet of the water supply assembly 101 , that is, at the pipeline extending from the water supply assembly 101 to the inside of the shell 200 , and the spray heads 102c - 1 serve as the outlet of the water supply assembly 101 .

[0079] In order to improve the atomization effect, a protrusion, a groove or an opening may be provided on the side of the lifting baffle 102b facing the outlet of the water supply component 101.

[0080] In some other embodiments, the spray spray switching component 102 includes a spray spray component 102c and a drive component 102d, the spray spray component 102c is connected to the outlet of the water supply component 101, and the drive end of the drive component 102d is used to drive the spray spray component 102c to switch to the spray mode or the spray mode.

[0081] Specifically, the present invention discloses that the spray spray assembly 102c is located above the condenser 300. At this time, correspondingly, the fan is also installed above the condenser 300 to facilitate blowing the spray toward the condenser 300.

[0082] The spray spray assembly 102c includes a spray head 102c-1 and a spray baffle 102c-2. There are multiple spray heads 102c-1, and the spray heads 102c-1 are connected to the outlet of the water supply assembly 101. Specifically, the spray heads 102c-1 are connected through a spray pipe, and the spray pipe is connected to the outlet of the water supply assembly 101. The spray heads 102c-1 can be evenly distributed above the condenser 300, or the spray heads 102c-1 can be arranged more densely above the position where the condenser 300 dissipates heat slowly, and the spray heads 102c-1 can be arranged more sparsely above the position where the condenser 300 dissipates heat quickly.

[0083] The driving end of the driving assembly 102d is connected to the spray baffle 102c-2 to drive the spray baffle 102c-2 to move to a position blocking the spray head 102c-1 or a position exposing the spray head 102c-1. It can be understood that the distance between the spray baffle 102c-2 and the spray head 102c-1 is sufficient for the water droplets to become mist.

[0084] Further, the present invention discloses that the number of spray baffles 102c-2 is equal to the number of spray heads 102c-1, and they are arranged one by one, and the spray baffles 102c-2 are connected by connecting rods, etc. It can be understood that the spray baffles 102c-2 can be connected as a whole by connecting rods in a row or a column, or all the spray baffles 102c-2 can be connected as a whole by connecting rods, and the specific connection form is not limited.

[0085] In order to improve the atomization effect, a protrusion, a groove or a hole may be provided on the surface of the spray baffle 102c-2 facing the spray head 102c-1.

[0086] Furthermore, the present invention discloses that the drive assembly 102d includes a translation driver, and the driving end of the translation driver is used to drive the spray baffle 102c-2 to translate in a preset plane. It should be noted that the preset plane is not limited to a horizontal plane, but also includes a plane with a certain slope to the horizontal direction. It can be understood that the horizontal plane here refers to a plane perpendicular to the vertical direction of the shell 200. The translation in the preset plane can be specifically along Figure 1 It can move in the left and right direction, or it can move horizontally in the front and back direction perpendicular to the paper.

[0087] The translation driver is a structure such as a cylinder, a hydraulic cylinder, an electric push rod or a gear rack. In order to facilitate the translation of the spray baffle 102c-2 and improve the strength of the spray baffle 102c-2, the present invention discloses that a guide rail or a slide groove that slides with the spray baffle 102c-2 is provided on the inner wall of the housing 200. When switching to the spray mode, each spray baffle 102c-2 can move to the gap position below two adjacent spray heads 102c-1 to avoid blocking the spray head 102c-1.

[0088] It should be noted that the drive assembly 102d may also include a rotary driver, which is used to drive the spray baffle 102c-2 to rotate. Specifically, the rotary driver is a rotary cylinder or a motor, etc., so that the spray baffle 102c-2 can rotate to the position directly below the spray head 102c-1, that is, the spray baffle 102c-2 is perpendicular to the spraying direction of the spray head 102c-1; or, the spray baffle 102c-2 rotates to a position parallel to the spraying direction of the spray head 102c-1.

[0089] It can be understood that the rotation of the spray baffle 102c-2 here can be along the direction perpendicular to the paper plane, along the direction parallel to the paper plane, or in other directions, and the specific rotation direction is not limited. Taking the rotation in the direction perpendicular to the paper plane as an example, in this case, multiple rows of spray baffles 102c-2 connected together by a rotating shaft can be arranged along the direction perpendicular to the paper plane, and a sprocket or pulley is installed at the end of each row of spray baffles 102c-2, and a sprocket or pulley is installed corresponding to the output end of the rotary drive, and the connection is connected by a chain or synchronous belt transmission.

[0090] In some other embodiments, the spray spray assembly 102c includes a spray head 102c-1 and a louver baffle 102c-3. The spray spray assembly 102c can be located above the condenser 300 or below the condenser 300. The spray spray assembly 102c is located above the condenser 300 as an example.

[0091] There are multiple sprinkler heads 102c-1, and sprinkler heads 102c-1 are connected to the outlet of water supply assembly 101. The driving end of driving assembly 102d is connected to shutter baffle 102c-3 to drive shutter baffle 102c-3 to open or close to block sprinkler head 102c-1 or expose sprinkler head 102c-1.

[0092] The switching of different modes is achieved by opening and closing the shutter baffle 102c-3.

[0093] In order to improve the atomization effect, a protrusion, a groove or an opening may be provided on the side of the shutter baffle 102c-3 facing the outlet of the water supply component 101.

[0094] In some other embodiments, the spray spray switching assembly 102 includes a spray head 102c-1, a spray head 102c-4 and a switching valve group, such as Fig. 9 shown.

[0095] The shower head 102c-1 and the spray head 102c-4 are both arranged in the shell 200, and the inlet of the switching valve group is connected to the outlet of the water supply component 101, and the outlet of the switching valve group is respectively connected to the shower head 102c-1 and the spray head 102c-4. The switching valve group is used to control the conduction between the water supply component 101 and the shower head 102c-1 or the spray head 102c-4 to realize the switching between showering and spraying.

[0096] Further, the present invention discloses that the shower head 102c-1 and the spray head 102c-4 are separately arranged, and are respectively located above, below and / or on the side of the condenser 300, or are respectively located below, above and / or on the side of the condenser 300, or are both located above the condenser 300, or are both located below the condenser 300, or are both located on the side of the condenser 300. It should be noted that the number of the shower head 102c-1 and the spray head 102c-4 are both multiple.

[0097] It should be noted that the shower head 102c - 1 and the spray head 102c - 4 may also be installed together and located above, below or on the side of the condenser 300 .
