Description

Technical Field

[0001] This invention relates to the field of heat dissipation device technology, and more specifically to an atomizer back clip that assists in air-cooled heat dissipation. Background Technology

[0002] During the charging process of drone batteries, the battery temperature may rise. Existing battery cooling methods include air cooling and using a powerful fan to blow on the surface of the battery, all of which use the removal of the surface temperature of the battery to achieve the purpose of cooling the battery.

[0003] Currently, the only battery cooling devices on the market are air-cooled. However, air-cooling is severely affected by environmental factors. At high temperatures, its cooling effect is poor, and under continuous battery operation, the battery will overheat significantly, leading to severe battery life loss. There are no patents for mist cooling for battery cooling on the market.

[0004] Therefore, improvements to existing technologies are necessary. Summary of the Invention

[0005] The purpose of this invention is to provide an atomizer back clip that assists in air cooling.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings: This invention provides an atomizer back clip to assist in air-cooled heat dissipation, comprising: The housing part 1 includes an atomizer back clip vent 11 and an atomizer back clip water tank 12; the top of the atomizer back clip water tank 12 is connected to the atomizer back clip vent 11.

[0028] Preferably, the housing portion 1 further includes an atomizer back clip electrical side plate 13; The atomizer back clip electrical side plate 13 is installed on the side of the atomizer back clip water tank 12.

[0029] To better illustrate the technical effects of the present invention, the present invention provides the following specific embodiments to illustrate the above technical process: Example 1: An atomizer back clip that assists in air cooling, comprising a housing part 1, a baffle plate 2, and an electronic control part 3.

[0030] The housing part 1 includes: an atomizer back clip vent 11, an atomizer back clip water tank 12, an atomizer back clip electrical side plate 13, and an atomizer back clip atomizer mounting clip 14. The atomizer back clip water tank 12 is connected to the atomizer back clip vent 11 via a clip connecting ear; the atomizer back clip electrical side plate 13 is connected to the atomizer back clip water tank 12 via screws. The atomizer back clip electrical side plate 13 is used to hide electrical components and fix the water pump, providing dust protection for the electrical components, and also for installing a power connector to supply power to the electrical components; the atomizer back clip atomizer mounting clip 14 is used to fix the atomizer 35.

[0031] The baffle 2 is used to separate the water and mist produced by the atomizer, allowing the water to flow back to the atomizer's back clip water tank, while the mist can pass through the baffle normally. The baffle 2 includes a horizontal plate with several elongated through holes. Several inclined plates corresponding to the through holes are fixedly installed at the top and bottom of the horizontal plate. The inclined plates extend from one side of the through holes to the top or bottom, and the upper and lower inclined plates are arranged in an array at a 60° angle. The structure is compact and can achieve the corresponding functions.

[0032] The electronic control unit 3 includes: an atomizer 35, a liquid level sensor 34, a water pump 33, an electronic control board 32, and a power plug 31. The atomizer 35, the liquid level sensor 34, and the water pump 33 are controlled by the electronic control board 32, and the power plug 31 supplies power to the electronic control board 32.

[0033] The novel baffle plate designed in this invention is used for water mist separation of mist, which can effectively prevent water generated by the atomizer from entering the battery and fan and causing irreversible damage to the battery and fan; at the same time, a large amount of water accumulating on the fan blades will affect the fan's blowing effect and reduce the fan's cooling effect. The baffle plate water mist separation can perfectly improve this effect.

[0034] In this invention, the mist after water mist separation consists of tiny particles of 3-10μm. When blown onto the battery by the wind, these particles are evaporated by the core temperature of the battery and absorb some heat, thus not affecting the battery. The fan can be an IP65 waterproof fan and will not be affected.

[0035] This invention designs an electronic control device. The circuit uses an STM32F103C8T6 minimum module as the main control chip, connecting to a power supply module, a water level sensor module, a water pump module, and an atomizer module. The power supply module uses a screw-type terminal block KF301. After filtering through a 100NF and a 10UF capacitor, it connects to a linear regulator LM7805MPX. The output is then filtered, reducing the 24V input voltage to a stable 5V. This 5V voltage then passes through a linear regulator AMS1117 and is filtered again, resulting in a 3.3V VCC power supply. The water level sensor module uses a screw-type terminal block KF301. The positive terminal is the 24V power supply, and the signal line is connected to an optocoupler. When the water level is reached, it outputs a high level, activating the other end and sending a high-level signal to the STM32F103C8T6 minimum module. Upon receiving this signal, the chip controls the water pump to shut down. The water pump module is centered around a 24V relay. After connecting to a 24V power supply, a general-purpose diode D_1N4007 is connected in parallel to protect the circuit. The control section is connected to the emitter of a transistor, the collector of the transistor is connected to the VCC output, and the base is connected to the chip pin. After receiving the control signal from the STM32F103C8T6 minimum module, the transistor controls the 24V relay, thereby controlling the on / off state of the water pump. The atomizer module consists of three 800uH and 25uH inductors connected to three screw-type KF301 terminals. One end of the inductor is connected to a MOSFET, and the MOSFET and chip pin are conductive. The STM32F103C8T6 minimum module generates a high-frequency oscillation circuit through PWM, which outputs to the MOSFET to control the atomizer to oscillate synchronously, breaking water droplets to produce water mist. The logic is to first turn on the water pump module, then delay the atomizer for five seconds before turning it on to prevent dry burning initially. Upon reaching the predetermined water level, the water level sensor sends a high-level signal, activating the optocoupler. The chip pin receives this high-level signal, shutting off the water pump. Once the water level drops, the water level sensor outputs a low-level signal, closing the optocoupler. The chip pin receives this low-level signal, and the water pump restarts after 2 seconds to pump water, thus achieving circulation. If the water level sensor does not output a high-level signal for more than 30 seconds, the atomizer is shut off to prevent prolonged dry burning.

[0036] Under the same conditions, the following are the experimental results of using both mist cooling and air cooling to cool the battery during charging:

[0037] This invention adds a mist cooling effect to the air cooling system, resulting in a significantly better cooling effect than existing technologies that only use air cooling. In experiments, the cooling effect of adding mist cooling in this invention is better than that of air cooling.

Any variations or substitutions within the technical scope disclosed in the present invention should be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
