Description

Technical Field

[0001] This utility model relates to the field of air cooler technology, and in particular to an air cooler structure with a cooling module. Background Technology

[0002] Air purifiers, as household appliances that combine ventilation and cooling functions, are widely used in homes, offices, and other places due to their low energy consumption and ease of use. The working principle of existing air purifiers mainly involves a water pump delivering water from a tank to an evaporative filter layer. Utilizing the physical property of water absorbing heat from the air during evaporation, and working in conjunction with a fan to expel the cooled air, a cooling effect is achieved.

[0003] However, the cooling effect of traditional air coolers is heavily dependent on the ambient humidity. In high humidity environments, the cooling effect is limited, and they cannot actively reduce the initial temperature of the circulating medium, resulting in low cooling efficiency and making it difficult to meet users' needs for rapid cooling. Utility Model Content

[0004] The main purpose of this utility model is to provide a cooling fan structure with a cooling module, which aims to solve the problems of traditional cooling fans that rely solely on evaporation for cooling, are greatly affected by ambient humidity, and have limited cooling range.

[0005] To achieve the above objectives, the present invention proposes a cooling fan structure with a cooling module, comprising a housing and a lower water tank, a water circulation component, a cooling module, an evaporative heat exchange component, and an air supply component disposed within the housing. The lower water tank is used to store the circulating medium. The input end of the water circulation component is connected to the lower water tank and is used to drive the circulation medium to flow. The input end of the cooling module is connected to the output end of the water circulation component and is used to cool the circulating medium. The evaporative heat exchange component is connected to the output end of the cooling module and is used to receive the cooled circulating medium and achieve heat exchange through medium evaporation. The air supply component is disposed on one side of the evaporative heat exchange component and is used to deliver the cooled air after heat exchange to the external space.

[0006] In one possible implementation, a control component is also included, which is electrically connected to the refrigeration module and is used to control the start / stop state of the refrigeration module and adjust its refrigeration power.

[0007] In one possible implementation, the cooling module includes a cooling chip, a heat sink, and a cooling fan that are electrically connected to the control component. The hot end of the cooling chip is attached to the heat sink, and the cooling fan is positioned corresponding to the heat sink.

[0008] In one possible implementation, an upper water tank is also included, with its input end connected to the output end of the refrigeration module and its output end connected to the evaporative heat exchange component, for receiving the cooled circulating medium.

[0009] In one possible implementation, the water circulation component includes a water pump and a delivery pipeline. The water pump's inlet is connected to the lower water tank, and its outlet is connected to the input of the refrigeration module via the delivery pipeline, for pumping the circulating medium in the lower water tank to the refrigeration module.

[0010] In one possible implementation, a water distribution assembly is provided between the output end of the upper water tank and the evaporative heat exchange assembly. The water distribution assembly includes a distribution pipe and several spray holes. The distribution pipe is connected to the output end of the upper water tank, and the spray holes are evenly distributed on the side of the distribution pipe facing the evaporative heat exchange assembly, for uniformly distributing the circulating medium to the evaporative heat exchange assembly.

[0011] This utility model's technical solution achieves dual cooling by pre-cooling the circulating medium using a refrigeration module and combining it with an evaporative heat exchange component. This enables the air temperature to be lowered even in high-temperature and high-humidity environments. Simultaneously, the buffering effect of the upper water tank and the uniform spray design of the water distribution component ensure stable heat exchange by the circulating medium, improving cooling stability and efficiency. Furthermore, a control component allows for control of the refrigeration module's start / stop status and adjustment of its cooling power, ensuring both effective cooling and reduced energy consumption. The overall structure is compact and easy to assemble, making it suitable for home and office use. Attached Figure Description

[0018] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] To address the problems in the background technology, this utility model proposes a cooling fan structure with a cooling module 4, including a housing 1 and a lower water tank 2, a water circulation component 3, a cooling module 4, an evaporative heat exchange component 6, and an air supply component 7 disposed within the housing 1. The lower water tank 2 is used to store the circulating medium. The input end of the water circulation component 3 is connected to the lower water tank 2 and is used to drive the circulation medium to flow. The input end of the cooling module 4 is connected to the output end of the water circulation component 3 and is used to cool the circulating medium. The evaporative heat exchange component 6 is connected to the output end of the cooling module 4 and is used to receive the cooled circulating medium and achieve heat exchange through medium evaporation. The air supply component 7 is disposed on one side of the evaporative heat exchange component 6 and is used to deliver the cooled air after heat exchange to the external space.

[0021] Combined with reference Figures 1 to 3 As shown, in this embodiment, the cooling fan structure includes a housing 1 and a water tank 2, a water circulation assembly 3, a cooling module 4, an evaporative heat exchange assembly 6, and an air supply assembly 7 integrated within the housing 1. The housing 1 serves as an overall support structure, with air inlets and outlets on its sides and front, respectively, forming an airflow channel. The water tank 2 is fixed to the bottom of the housing 1 and stores the circulating medium (preferably water, but a mixture with added humectant can also be used). The top of the water tank 2 has a removable cover for easy water replenishment and cleaning. The cooling module 4 is the core cooling component, including a semiconductor cooling chip 41, a heat sink 42, and a cooling fan 43. The cold end of the semiconductor cooling chip 41 is bonded to the outer wall of the circulating medium pipe via thermally conductive silicone, while the hot end is tightly connected to the heat sink 42. The cooling fan 43 is installed on the side of the heat sink 42 away from the cooling chip 41. When the cooling module 4 is working, the cold end of the semiconductor cooling chip 41 absorbs the heat of the circulating medium, thereby reducing the temperature of the medium; while the heat generated at the hot end is dissipated to the outside of the housing 1 through the heat sink 42 and the cooling fan 43, so as to avoid heat accumulation and affect the cooling efficiency.

[0022] The evaporative heat exchange component 6 is located in the middle of the shell 1, between the air inlet and the air outlet. Its main body is a honeycomb paper core or hydrophilic fiber layer, possessing a large surface area. Its top is connected to the output end of the refrigeration module 4 via a water distribution pipe. Spray holes 92 are evenly distributed at the bottom of the water distribution pipe, ensuring that the circulating medium cooled by the refrigeration module 4 uniformly wets the surface of the evaporative heat exchange component 6. The air supply component 7 includes an axial flow fan and an air guide frame. The fan is fixed to the side of the evaporative heat exchange component 6 near the air outlet. The air guide frame is trumpet-shaped, with its small-diameter end connected to the fan and its large-diameter end corresponding to the air outlet, used to guide the airflow direction. When the fan is working, external air enters the shell 1 through the air inlet, flows through the evaporative heat exchange component 6, and contacts the low-temperature, moist medium surface. Secondary cooling is achieved through evaporative heat absorption, and finally, the cooled air is discharged through the air outlet.

[0023] The proposed structure pre-lowers the temperature of the circulating medium through the refrigeration module 4, and combines it with evaporative heat exchange to form a dual cooling mechanism. This solves the problems of traditional air coolers having small cooling range and being greatly affected by ambient humidity, and can still maintain a significant cooling effect in high temperature and high humidity environments.

[0024] In one possible implementation, a control component 8 is also included, which is electrically connected to the cooling module 4 and is used to control the start / stop state of the cooling module 4 and adjust its cooling power.

[0025] Combined with reference Figure 2 As shown, in this embodiment, the control component 8 is primarily a control circuit board integrated with a microprocessor, electrically connected to the semiconductor cooling module 4, water circulation component 3, and air supply component 7 via wires. If the temperature is below a threshold, the cooling power can be automatically reduced or the semiconductor cooling module 4 can be shut down. The input end of the control component 8 is connected to a temperature sensor and an operation panel. The temperature sensor can be embedded in the circulation medium pipeline at the output end of the cooling module 4, or located in the upper water tank 5, or inside the lower water tank 2, and is connected to the control circuit board for signal transmission. The control circuit board can control the start and stop of the semiconductor cooling module 4 based on the water temperature data detected by the temperature sensor. The operation panel is located on the outer surface of the housing 1 for easy manual input of control commands by the user. This control component 8 solves the problem that traditional air coolers cannot adjust the cooling intensity according to actual needs, maintaining efficient operation under different ambient temperatures, avoiding energy waste, and improving user flexibility and comfort.

[0026] In one possible implementation, the cooling module 4 includes a cooling chip 41, a heat sink 42, and a cooling fan 43 that are electrically connected to the control component 8. The hot end of the cooling chip 41 is attached to the heat sink 42, and the cooling fan 43 is disposed corresponding to the heat sink 42.

[0027] In one possible implementation, an upper water tank 5 is also included, the input end of which is connected to the output end of the refrigeration module 4, and the output end is connected to the evaporative heat exchange component 6, for receiving the cooled circulating medium.

[0028] Combined with reference Figure 2 and Figure 3 As shown, in this embodiment, the upper water tank 5 is a closed box structure made of food-grade plastic, with an inlet at the top and an outlet at the bottom. The entire structure is fixed to the top of the housing 1 via a fixing structure. The upper water tank 5 is sealed to the output pipe of the refrigeration module 4 through its top inlet. When the circulating medium, cooled by the refrigeration module 4, is discharged from the output of the refrigeration module 4, it flows naturally into the upper water tank 5 through the connecting pipe. The closed cavity structure of the upper water tank 5 allows for temporary storage of these low-temperature circulating media, preventing flow fluctuations caused by their direct and rapid flow to the evaporative heat exchange component 6. Simultaneously, the outlet at the bottom of the upper water tank 5 is connected to the input of the evaporative heat exchange component 6. Through natural drainage or control valve adjustment at the outlet, the temporarily stored low-temperature circulating medium can be stably and continuously delivered to the evaporative heat exchange component 6, achieving a continuous process of receiving, temporarily storing, and stably supplying the cooled circulating medium.

[0029] Furthermore, a liquid level sensor can be installed inside the upper water tank 5. This sensor is electrically connected to the control component 8. When the liquid level of the medium in the tank is lower than a preset value, the control component 8 can automatically start the water circulation component 3 to replenish the medium, ensuring that the evaporative heat exchange component 6 is always in a moist state. An overflow pipe can also be optionally installed so that when the water level in the upper water tank 5 exceeds a set height, the water flows back to the lower water tank 2 through the overflow pipe.

[0030] In one possible implementation, the water circulation component 3 includes a water pump 31 and a delivery pipeline 32. The water inlet of the water pump 31 is connected to the lower water tank 2, and the water outlet is connected to the input of the refrigeration module 4 through the delivery pipeline 32, for pumping the circulating medium in the lower water tank 2 to the refrigeration module 4.

[0031] Combined with reference Figures 2 to 3 As shown, in this embodiment, the water pump 31 can be a DC brushless water pump 31, which is fixed to the inner bottom of the lower water tank 2 by a waterproof bracket. Its inlet end can be equipped with a filter cover made of fine mesh to prevent impurities in the lower water tank 2 from entering the water pump 31 and causing blockage. The outlet end of the water pump 31 is sealed to the delivery pipeline 32 via a quick-connect fitting. The delivery pipeline 32 is made of food-grade silicone tubing, and its routing follows a pre-set groove inside the housing 1 to avoid interference with other components. The other end of the delivery pipeline 32 is connected to the input end of the refrigeration module 4 via a sealed fitting, forming a complete media delivery path from the lower water tank 2 to the refrigeration module 4. The water pump 31 is electrically connected to the control component 8, and its speed can be adjusted according to the working state of the refrigeration module 4.

[0032] In one possible implementation, a water distribution assembly 9 is provided between the output end of the upper water tank 5 and the evaporative heat exchange assembly 6. The water distribution assembly 9 includes a diversion pipe 91 and a plurality of spray holes 92. The diversion pipe 91 is connected to the output end of the upper water tank 5, and the spray holes 92 are evenly distributed on the side of the diversion pipe 91 facing the evaporative heat exchange assembly 6, for uniformly distributing the circulating medium to the evaporative heat exchange assembly 6.

[0033] Combined with reference Figure 2 As shown, in this embodiment, the water distribution assembly 9 serves as a key structure connecting the upper water tank 5 and the evaporative heat exchange assembly 6. Its main body is a hollow distribution pipe 91 made of corrosion-resistant plastic. One end of the distribution pipe 91 connects to the output end of the upper water tank 5, and the other end facing the evaporative heat exchange assembly 6 has several spray holes 92 machined along its length. When the circulating medium, cooled by the cooling module 4, flows from the upper water tank 5 into the distribution pipe 91, under water pressure, the medium is evenly sprayed onto the surface of the evaporative heat exchange assembly 6 in the form of a fine water stream through each spray hole 92, ensuring that the hydrophilic material of the evaporative heat exchange assembly 6 is fully wetted.
