And, because the whole latus rectum of water-cooling chamber is less, the instantaneous pressure release when water passes through the last accent in water-cooling chamber forms the jet, and the jet hits on first inclined plane to form water smoke, water smoke and outside air's area of contact is great this moment, and the radiating effect of water is better, and this water smoke splash to the second inclined plane, and fall back to in the water catch bowl, in order to accomplish the circulation collection of water.

Moreover, because the overall drift diameter of the water cooling cavity 220 is smaller, the instantaneous pressure is released when water passes through the upper cavity opening of the water cooling cavity 220, a jet flow is formed, the jet flow hits the first inclined surface 185 to form water mist, at the moment, the contact area of the water mist and the external air is larger, the heat dissipation effect of the water is better, the water mist is sputtered to the second inclined surface 186, the water on the second inclined surface 186 is adsorbed by the water-absorbing non-woven fabric, so that the contact time of the water and the external air is prolonged, the heat dissipation effect of high-temperature water is improved, and after the water of the water-absorbing non-woven fabric is absorbed to a certain degree, the redundant water falls back into the water collecting tank 18 to complete the water circulation collection.
When strong refrigeration is needed, the straight reciprocating pushing structure 123 forces the vertical plate 121 and the mounting plate 12 to be far away from each other along the width direction of the fins 23, the dovetail blocks of the driving strips 126 are matched with the dovetail groove sections 224 of the copper strips 22 to pull away the vertical sections 222 on two sides, the drift diameter of the part is increased, meanwhile, the wave flexible sections 223 are limited by the vertical protrusions 221, the wave flexible sections 223 are difficult to move along with the driving strips 126, so that the wave flexible sections 223 are adaptively deformed, the wave flexible sections 223 are deformed to be approximately vertical, namely, the distance between the two wave flexible sections 223 is also adaptively increased, namely, the drift diameters of the wave flexible sections 223 and the vertical sections 222 are increased, so that the overall drift diameter of the water cooling cavity 220 is increased, under the condition of certain water pressure, the overall water flow in the water cooling cavity 220 is increased, thereby greatly improving the heat dissipation effect, and the mounting plate 12 is moved to be wholly exposed to the state of the cabinet body 1, and therefore, the external air is rapidly introduced into the air cooling cavity 230 through the guide of the guide plate 122, thereby further improving the cooling effect.
Therefore, under the control of the linear reciprocating pushing structure 123, the water cooling cavity 220 has at least two states, and under the premise that the output water pressure is relatively stable (the gravity of the counterweight pressing block 52, the tension of the first spring 541, and the output water pressure converted by the pressure of the second spring 531), the flow rate of the water cooling cavity 220 is relatively stable in the two states, the change is small, and the water flow rate of the water cooling cavity 220 in the two states is greatly changed (the water flow rate with large water flow rate of the water cooling cavity 220 and the water flow rate with small water flow rate of the water cooling cavity 220) so as to conduct targeted heat dissipation aiming at two different working conditions.
The above two conditions are long-time conditions, and in some short-time conditions, the water cooling chamber 220 has the following two conditions:
in the first state, when the vapor compression refrigeration unit 3 is just started to start refrigerating, the vapor compression refrigeration unit 3 conveys a high-temperature and high-pressure refrigerating medium to the heat exchange tube 21 positioned below, at this time, the two linear reciprocating pushing structures 123 positioned below are started, the two linear reciprocating pushing structures 123 positioned above are not started, that is, the lower part of the mounting plate 12 and the lower part of the riser 121 are far away from each other, so that the mounting plate 12 and the riser 121 are splayed, the lower structure of the mounting plate 12 is exposed to the cabinet body 1, at this time, the copper strips 22 deform, the distance between the copper strips 22 at two sides is gradually reduced from bottom to top, the copper strips 22 are splayed, the cross-sectional area of the water cooling cavity 220 is gradually reduced from bottom to top, therefore, the drift diameter of the lower part of the water cooling cavity 220 is larger, the water flow at this part is larger, the heat exchange tube 21 positioned below can be effectively cooled in time, meanwhile, the lower structure of the guide plate 122 is exposed to the cabinet body 1, and external air is guided by the guide plate 122 to enter the lower part of the accommodating cavity 10 rapidly, so that the heat exchange tube 21 is cooled in time.
Then, the two straight reciprocating pushing structures 123 located above are started slowly, namely the mounting plate 12 and the vertical plate 121 are integrally far away from each other, the mounting plate 12 and the vertical plate 121 are in a vertical state, and the overall drift diameter of the water cooling cavity 220 is increased so as to dissipate heat of the overall heat exchange tube 21.
In the second state, when the refrigerating state of the cabinet body 1 needs to be further cooled, namely, the flow speed of the refrigerating medium in the heat exchange tube 21 is accelerated, and meanwhile, the refrigerating medium in the heat exchange tube 21 positioned above is about to flow into the evaporator 33, at the moment, the two straight reciprocating pushing structures 123 positioned above are started, the two straight reciprocating pushing structures 123 positioned below are not started, namely, the upper part of the mounting plate 12 and the upper part of the riser 121 are mutually far away, so that the mounting plate 12 and the riser 121 are in an inverted splayed shape, the upper structure of the mounting plate 12 is exposed to the cabinet body 1, at the moment, the copper strips 22 deform, the distance between the copper strips 22 at two sides is gradually increased from bottom to top, the copper strips 22 at two sides are also in an inverted splayed shape, and the cross section area of the water cooling cavity 220 is gradually increased from bottom to top, so that the diameter of the upper part of the water cooling cavity 220 is larger, the water flow at the part is larger, the heat exchange tube 21 positioned above can be effectively cooled in time, and simultaneously, the upper structure of the baffle 122 is exposed to the cabinet body 1, and external air is guided by the baffle 122 to enter the upper part of the air cooling cavity 230 rapidly, so that the heat exchange tube 21 is cooled in time; in this process, the copper strip 22 is in an inclined state, so that the upper cavity opening of the water cooling cavity 220 is lowered and is lower than the water level of the water collecting tank body 18, and therefore water in the water collecting tank body 18 flows backward to the upper part of the water cooling cavity 220, and water is timely supplemented to the water cooling cavity 220, heat dissipation of the heat exchange tube 21 positioned above is improved, and the heat dissipation response speed is greatly improved.
Then, the two straight reciprocating pushing structures 123 located below are started at a retarded speed, namely the mounting plate 12 and the vertical plate 121 are integrally far away from each other, the mounting plate 12 and the vertical plate 121 are in a vertical state, and the overall drift diameter of the water cooling cavity 220 is increased so as to dissipate heat of the overall heat exchange tube 21.
Namely, the starting sequence and starting time of the upper linear reciprocating pushing structure 123 and the lower linear reciprocating pushing structure 123 are set to change the local path of the water cooling cavity 220, so that the rapid cooling is effectively performed according to the flow velocity of the refrigeration medium of the local heat exchange tube 21, and the refrigeration response speed is further improved.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
