Description

Technical Field

[0001] The utility model relates to the technical field related to air-cooling equipment for an outdoor unit of an air conditioner, in particular to a coil device for the air-cooling equipment. Background Art

[0002] With the country's formulation of green development goals for "energy conservation and carbon reduction," as well as "carbon peak" and "carbon neutrality," the concepts of energy conservation and efficiency are gaining increasing attention across all industries. Regarding split air conditioners, statistics show that my country's annual production of split air conditioners reached 150 million units in 2015. Historical data reveals that when the ambient temperature exceeds 35°C, with condensate cooling the outdoor unit's inlet air, the indoor unit's outlet air temperature drops by 0.4-0.8°C; the outdoor unit's exhaust air temperature drops by 0.1-0.5°C; the inlet air temperature drops by approximately 2°C; and the air conditioner's power consumption decreases by 30W.

[0003] Therefore, energy-saving technical transformation to reduce the outdoor unit inlet air temperature has become one of the effective measures. The technical measures commonly used in current related research are to use a spraying device to add a large amount of make-up water to the condenser surface of the split air conditioner and use a water pump to spray the water to reduce the outdoor unit inlet air temperature. Although this method recovers the residual cold of the condensed water and helps to reduce the outdoor unit inlet air temperature to a certain extent, it requires not only an additional water pump to provide energy during implementation, but also a certain amount of cooling water supply, resulting in a waste of water resources. Moreover, when spraying directly on the condenser, the condenser comes into direct contact with the water, causing scaling of the condenser and affecting the heat dissipation effect of the outdoor unit itself. Summary of the Invention

[0004] The purpose of the present invention is to provide a coil device for air cooling equipment to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A coil device for air-cooling equipment includes an air-conditioning outdoor unit and a heat dissipation structure installed on the air-conditioning outdoor unit. The heat dissipation structure is through-shaped and connected to the air inlet on the air-conditioning outdoor unit. The heat dissipation structure includes an outer shell and a condenser arranged through the outer shell. Both ends of the condenser are formed with an inlet pipe for the inflow of condensed water and an outlet pipe for the discharge after heat exchange.

[0007] The coil device of the air-cooling equipment as described above: the condensing tube includes three groups of cross-arranged first coils, second coils and third coils.

[0008] The coil device of the air-cooling equipment as described above: the first coil, the second coil and the third coil are distributed in a spiral line.

[0009] In the coil device of the air-cooling equipment as described above, the first coil, the second coil and the third coil are distributed in a serpentine line.

[0010] The coil device of the air-cooling equipment as described above: four-way valves are installed at both ends of the first coil, the second coil and the third coil, and the two four-way valves are connected to the water inlet pipe and the water outlet pipe respectively.

[0011] The coil device of the air-cooling equipment as described above: the water inlet pipe is connected to an overflow pipe, and one end of the overflow pipe away from the water inlet pipe is connected to the water outlet pipe.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The detachable condenser tube does not change the original design of the split air conditioner, nor does it require additional power or water supply. It can be installed or removed according to user needs, meeting flexible usage requirements.

[0014] The use of three groups of staggered coils can recycle and reuse low-temperature air-conditioning condensate, increase the contact area between low-temperature air-conditioning condensate and wind, fully exchange heat, reduce the condenser inlet air temperature, improve energy saving effects, and avoid direct contact between recovered condensate and condenser.

[0021] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0022] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0023] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0024] See also Figures 1 to 5 In an embodiment of the utility model, a coil device of an air-cooling device includes an air-conditioning outdoor unit 1 and a heat dissipation structure installed on the air-conditioning outdoor unit 1. The heat dissipation structure is in a through-shape and is connected to the air inlet 2 on the air-conditioning outdoor unit 1. The heat dissipation structure includes an outer shell 5 and a condenser 7 arranged through the outer shell 5. Both ends of the condenser 7 are formed with an inlet pipe 8 for the inflow of condensed water and an outlet pipe 9 for discharge after heat exchange.

[0025] In detail, in this embodiment, the coil device of the air-cooling equipment described in the present invention is adopted. When in use, when the split air-conditioning system is started, the air-conditioning outdoor unit 1 is put into use, and the low-temperature air-conditioning condensate flows into the condenser tube 7 from the water inlet pipe 8. The condensed water fills the condenser tube 7 under the action of atmospheric pressure, and the wind enters from the air inlet side 6 of the outer shell 5, passes through the condenser tube 7 and performs heat exchange with the low-temperature condensate in the condenser tube 7. After the heat exchange is completed, the wind cooled down passes through the air inlet 2 of the air-conditioning outdoor unit 1 and enters the interior of the air-conditioning outdoor unit 1, and performs heat exchange with the condenser 4 in the air-conditioning outdoor unit 1. After the heat exchange is completed, it is discharged from the air outlet 3 formed at the side end of the air-conditioning outdoor unit 1, ensuring heat exchange while avoiding direct contact between the recovered condensate and the condenser 4, avoiding scaling of the condenser 4 and affecting the heat dissipation effect of the air-conditioning outdoor unit 1 itself.

[0026] The outer shell 5 is in a through shape, with one end connected to the indoor unit of the air conditioner and the other end connected to the air inlet 2 of the outdoor unit 1 of the air conditioner.

[0027] Preferably, the condenser 7 includes three groups of cross-arranged first coils 701 , second coils 702 and third coils 703 .

[0028] In contrast, the commonly used technical measures to reduce the outdoor unit inlet air temperature at present are to use a sprinkler device to collect the condensed water recovered from the split air conditioner and add a large amount of make-up water, and use a water pump to spray the water on the condenser surface to reduce the outdoor unit inlet air temperature. This allows the condensed water to come into direct contact with the condenser, causing scaling of the condenser and affecting the heat dissipation effect of the outdoor unit itself. The use of a coil form can ensure the heat exchange effect and realize the recovery of residual cold while reducing the condenser inlet air temperature, thereby reducing the energy consumed by the condenser and avoiding direct contact between the recovered condensed water and the condenser.

[0029] In the absence of the need to supplement external power, the communicating vessel principle is utilized, and an upper supply and lower return method is adopted, wherein the first coil 701, the second coil 702 and the third coil 703 are made of copper tubes, so that the condensed water can flow under gravity and atmospheric pressure.

[0030] The condenser 7 is detachably connected to the housing 5, so that the user can choose to set or disassemble it according to needs, which meets the needs of flexible use.

[0031] In one embodiment, the first coil 701 , the second coil 702 , and the third coil 703 are distributed in a spiral line.

[0032] In another embodiment, the first coil 701 , the second coil 702 and the third coil 703 are distributed in a serpentine line.

[0033] Among them, the first coil 701, the second coil 702 and the third coil 703 are set as spiral lines or serpentine lines respectively, mainly to improve the heat exchange efficiency and the flow performance of the fluid, so that the heat exchange area is increased when air enters the shell 5, thereby improving the overall condensation efficiency.

[0034] As a further solution to this problem, please refer to Figure 2 and Figure 3 Four-way valves are installed at both ends of the first coil 701, the second coil 702 and the third coil 703, and the two four-way valves are connected to the water inlet pipe 8 and the water outlet pipe 9 respectively.

[0035] It should be noted that the diameters of the water inlet pipe 8 and the water outlet pipe 9 are the same, and the diameters of the first coil 701, the second coil 702 and the third coil 703 are the same and smaller than the diameters of the water inlet pipe 8 and the water outlet pipe 9. This is mainly to ensure that the condensed water flowing into the water inlet pipe 8 can be respectively gathered into the first coil 701, the second coil 702 and the third coil 703.

[0036] As a further solution to this problem, please refer to Figure 1 The water inlet pipe 8 is connected to an overflow pipe 10, and one end of the overflow pipe 10 away from the water inlet pipe 8 is connected to the water outlet pipe 9.

[0037] The overflow pipe 10 is mainly used to ensure the convenience of the entire system when the amount of condensed water is large in high temperature seasons and to prevent the overflow of condensed water from affecting the outdoor environment.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
