A sufficient amount of normal temperature water flow is converted into extremely fine mist to accelerate evaporation and absorb heat for cooling, and two sets of large-area splash vanes operating in reverse at high speed are used to continuously and repeatedly spray out sufficient water flow, which is then converted into extremely fine mist particles with the maximum total surface area by countless micro vortex cyclones. The water vapor saturation at the liquid-gas interface is reduced in the sound field to accelerate the speed at which the mist evaporates.

Description

[Technical field]

[0001] The present invention is in the field of high velocity evaporating water flow cooling electrical equipment. [Background technology]

[0002] Traditional electric "air conditioner" cooling equipment absorbs heat by boiling and evaporating a certain working medium. In addition to polluting the environment, the working medium needs to be circulated and recovered, which consumes a lot of energy. Furthermore, the heat inside the room is still only discharged to the outside, and the heat generated by the electricity consumed during the phase change transformation must also be added, which releases a lot of heat energy, which can only greatly increase the temperature of the ground environment and further increase the atmospheric temperature.

[0003] Therefore, a good way to cool the air is to take the heat near the ground to the sky and then release it. Water, which has the largest heat of vaporization, is selected as the working medium to cool the air by vaporization. According to the specifications of the largest central air conditioners currently available on the market, a cooling capacity of 220 kW requires a power consumption of 50 kW. This cooling capacity is roughly equivalent to the heat absorbed by 100 cc of vaporized water per second. In other words, to achieve this cooling purpose, only 100 cc of water per second needs to be vaporized to obtain the cooling capacity of a central air conditioner with a cooling capacity of 220 kW. Compared to the power consumption of an electric air conditioner, this not only saves a large amount of electric energy, but also has an excellent effect on environmental protection, since the only thing discharged is ordinary water that does not need to be collected.

[0004] In the current technology, water, which has the largest heat of vaporization at room temperature, is used as the working medium to absorb heat and cool, and there is no need to recover water vapor. However, the vaporization method using water as the working medium can only absorb heat by vaporization in the form of surface evaporation, not by internal vaporization, i.e. boiling, so for cooling electrical equipment whose main design objective is to absorb heat, the effect that can be achieved by this heat absorption method, which has a too slow vaporization speed, is still not up to practical requirements. At the current existing technology level, there is still a certain degree of difficulty in achieving such a sufficient cooling effect. Summary of the Invention [Problem to be solved by the invention]

[0005] In the patent for "Device and system for cooling by evaporating water into mist" with patent number ZL200810148953.7, a technical means is proposed to greatly increase the total surface area of ​​liquid water to improve its evaporation rate and achieve a cooling effect of rapidly absorbing heat, as compared with the method of normal electric air conditioners in which the liquid working medium boils and vaporizes internally at the same time, thereby rapidly absorbing heat. Based on this, the present invention further improves such a device, forming two sets of large-area splash surfaces using many splash vanes operating in reverse at high speed, continuously spraying a sufficient amount of water flow repeatedly and sufficiently, converting it into extremely fine mist particles with the maximum total surface area through countless micro vortex cyclones, and then greatly reducing the water vapor saturation degree at the liquid-gas interface of the mist particles in the ultrasonic sound field, and rapidly vaporizing all the mist particles to absorb heat. In the present invention, in order to solve the technical problem of atomizing a sufficient amount of water into ultra-fine particles and accelerating evaporation, two sets of large-area splash vanes rotating inversely are used to sufficiently spray a sufficient amount of water flow, and this repeated spraying process atomizes the working medium, which is water, while simultaneously stirring up the air in the atomization space, stirring up countless micro-vortex cyclones, and further dividing these fine mist particles into smaller particles, so that these ultra-fine mist particles have the largest total surface area and improve their evaporation speed. And, the sonic waves disturb and destroy the saturation gradient of water vapor that exists at the gas-liquid interface of the micro-water droplets, which has a particularly serious inhibitory effect on the evaporation phase transition speed, greatly reducing the saturation of the water vapor at the interface, accelerating the diffusion of the evaporated water vapor at the liquid surface, greatly improving the evaporation and evaporation speed of the liquid at the liquid-gas interface, and achieving the effect of further accelerating the evaporation speed of the mist. [Means for solving the problem]

[0006] The specific configuration of the means is to set up one vaporization chamber, and use two sets of cylindrical splash vane grid racks, each with the same axis, which intersect and engage with each other and rotate at high speed facing each other, and these cylindrical splash vane grid racks are formed as stanchions from splash vanes with a certain curved shape, and these two sets of cylindrical splash vane grid racks are fixed to two corresponding upper and lower trays to spray the injected water flow. The two trays are respectively pulled by two driving rotary shafts that engage with each other on the same axis and rotate in opposite directions to each other, and rotate at high speed, moving the two sets of mutually engaged cylindrical splash vane grid racks to rotate in opposite directions to each other, so that the injected water flow is continuously repeated and sufficiently sprayed as extremely fine mist particles. And the two sets of cylindrical splash vane grid racks that rotate in opposite directions at high speed further stir up the air in the space of the vaporization chamber into countless micro vortex cyclones. One bottom of the cylindrical splash vane grid rack is fixed to the tray connected with the driving shaft. Another floating edge is engaged with the bottom of another pair of corresponding cylindrical splash vane grid racks, that is, the track groove of the opposite tray, by a ceramic bearing or pulley, so that the two pairs of splash vane grid racks can be supported and rotated stably. A vaporizer cover is provided in the center of the upper tray, and the driving shaft passes through a large round hole in the center and is fastened to the center of several air compression fan blades provided under the round hole of the vaporizer cover, and the several air compression fan blades connected with the upper tray move the upper tray and the cylindrical splash vane grid rack in the upper tray to rotate together at high speed. The lower tray is fixed to the reverse driving shaft and is rotated in reverse by the driving shaft, so that the cylindrical splash vane grid rack in the lower tray moves and rotates together at high speed. At the same time, a water flow is introduced through the sprinkler tap so that a sufficient amount of water flows into the space between the two trays and splashes onto the cylindrical splash vane grid rack. The water is then sprayed back and forth by the counter-rotating splash vanes of the cylindrical splash vane grid rack many times, and is atomized into ultra-fine particles step by step.

[0007] In order to improve the evaporation rate of water, an ultrasonic sound field is further installed in the outer space of the evaporation chamber, the air outlet, and the air duct, and a sound field is generated in the outer space with strong reactive power to obtain resonance of the sound waves, and the saturation gradient of the water vapor at the gas-liquid interface of the outputted micro-water droplets is greatly disturbed and changed. The water vapor saturation sensor at the outlet of the air duct limits the maximum water intake of the water regulator. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The present invention will now be further described with reference to the drawings and examples.

[0015] In order to allow those skilled in the art to better understand the present invention, more clearly define the scope of protection claimed by the present invention, and implement the invention accordingly, the present invention will be described in detail below with reference to some specific embodiments of the present invention. Note that the following are only some specific embodiments of the spirit of the present invention, and are merely some examples of the present invention, and the specific and direct description of the technical ideas and features of the relevant structures therein is merely for the purpose of making the content of the present invention easier to understand and implement accordingly, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. All modifications, ordinary selections and substitutions made by those skilled in the art under the guidance of the spirit and substantial ideas of the main technical means of the present invention should be included in the scope of protection claimed by the present invention.

[0016] In the vaporization chamber driven by the twin motors, a powerful drive motor 26 drives a drive shaft 27 of the drive motor, which moves a lower tray 36 and a set of concentric cylindrical surface splash vane grid racks 38 fixed to the lower tray 36 to rotate at high speed, and a drive shaft 29 of another powerful drive motor 28, which rotates at high speed in the opposite direction, drives an upper tray 33 and another set of concentric cylindrical surface splash vane grid racks 37 fixed to the upper tray 33 through an air compression fan blade 35 connected to the reverse drive shaft, which rotates the set of concentric cylindrical surface splash vane grid racks 38 in the opposite direction at high speed, forming many micro vortex cyclones that further atomize water droplets into ultra-fine particles. The water flow regulator 43 defined by the water vapor saturation sensor controls the water intake pipe 52 to introduce the water flow into the nozzle 44 of the vaporizer, which then splashes into the vaporizer, where it is swayed by the large-area splash vanes of the cylindrical splash vane grid rack operated at high speed by the spoke-shaped splash tray 45 and splashed into fine mist, and is repeatedly scattered together with the air flow by the large-area splash vanes of the two sets of cylindrical splash vane grid racks, and is divided into extremely fine mist by the countless micro vortex cyclones in the vaporizer. When passing through the air duct, and under the intense sonic vibration driven by the piezoelectric ceramic pieces 32, the saturation gradient of water vapor at the liquid-gas interface of the mist droplets is destroyed, which speeds up the evaporation speed of the liquid water.

[0017] The effects of the present invention are as follows.

[0018] This type of cooling electrical equipment using water as the working medium is simple in structure, reliable, and easy to use compared to electric air conditioners, and has relatively low resource requirements. It can be widely used in transportation facilities, vehicles, ships, subways, underwater vehicles, and spacecraft, and is particularly suitable as a portable work-related accident insurance device for outdoor work and jobs such as traffic police officers who perform regular shifts.

[0019] In addition to the significant environmental and energy-saving effects, large-scale evaporation can eliminate the trouble of using seawater as a water source and depleting fresh water sources; in addition to producing industrial salt products as a by-product, large-scale evaporation can also cool the region and even the planet.

[0020] With a cold source, water vapor from which most of the salt has been evaporated and filtered out, and further research and development based on simple machinery and cheap energy consumption, desalinating large amounts of seawater is no longer an impossible fairy tale for coastal desert regions where water is more valuable than oil.

[0021] Companies with serious wastewater discharge needs can use such equipment to concentrate polluted water and recover waste products to reduce wastewater discharge.

[0022] In addition, poor areas can get affordable cooling appliances that the public can afford.
