Description

Technical Field

[0001] The utility model relates to the technical field of air coolers, in particular to a double heat dissipation structure of an air cooler. Background Art

[0002] Air coolers are divided into industrial air coolers and household air coolers. Industrial air coolers are generally used in cold storage and cold chain logistics refrigeration environments. Household air coolers are also called water-cooled air conditioners. They are evaporative cooling and ventilation units that integrate cooling, ventilation, dust prevention, and deodorization. The cooling principle is: when the fan is running, it enters the cavity to generate negative pressure, so that the air outside the machine flows through the porous wet curtain surface, forcing the dry bulb temperature of the air passing through the curtain to drop to a temperature close to the wet bulb temperature of the air outside the machine, that is, the dry bulb temperature at the outlet of the air cooler is 5-12℃ lower than the outdoor dry bulb temperature (up to 15℃ in dry and hot areas). The drier and hotter the air, the greater the temperature difference and the better the cooling effect.

A dual heat dissipation structure of an air cooler, comprising a main frame; external filter frames are slidably arranged on both sides of the main frame; a fan is arranged on the upper part of the main frame; a water tank is fixedly arranged on the outer side of the main frame; a wet curtain is fixedly arranged on the inner side of the main frame; the external filter frame and the main frame are vertically slidably connected, the external filter frame is on the outer side of the wet curtain, the upper slider and the upper air outlet are slidably connected, a lower support spring is fixedly arranged at the bottom of the external filter frame, the bottom end of the lower support spring is fixedly connected to the main frame, and an upper slider is fixedly arranged on the upper part of the external filter frame. The practical external filter frame vibrates up and down to shake off and reduce branches and dust attached to the external filter frame itself, so as to keep the air intake of the external filter frame unobstructed. The following problems exist in the prior art:

[0004] The current air cooler has a single heat dissipation structure, resulting in a poor heat dissipation effect. At the same time, since the current publication number CN218511296U uses the filter in the external filter frame to filter and prevent dust and dirt from entering the interior, the filter surface is covered with a lot of dust after long-term use, thus affecting ventilation.

[0027] The air inlets 2 on the left and right sides of the box body 1 are arranged to facilitate air intake. The outside air enters the box body 1 under the action of the fan 18 inside the box body 1, and the water tank 3 is arranged to facilitate heat dissipation.

[0028] like Figure 2As shown, a square vent which is connected up and down is provided on the upper surface of the inner wall of the box body 1, and a protective component 11 is fixedly connected to the left and right sides of the inner wall of the box body 1, and a wet curtain plate 12 is fixedly connected to the outer surface of the protective component 11, and a wet curtain sheet 13 is fixedly connected to the middle of the wet curtain plate 12, and a first water pump 14 is fixedly connected above the outer surface of the wet curtain plate 12, and the input end of the first water pump 14 passes through the rear outer side of the inner wall of the box body 1, and the input end of the first water pump 14 is fixedly connected to the water tank 3, and the output end of the first water pump 14 is fixedly connected to the outer surface of the wet curtain plate 12, and a pad 15 is fixedly connected to the upper back of the wet curtain plate 12, and an L-shaped plate 16 is fixedly connected to the upper outer surface of the pad 15, and a fixed Plate 17, a fan 18 is fixedly connected to the upper surface of the fixed plate 17, a wet curtain assembly 1101 is fixedly connected to the lower part of the L-shaped plate 16 in the vertical direction, the structure of the wet curtain assembly 1101 is the same as that of the wet curtain plate 12 and the wet curtain sheet 13, a second water pump 19 is fixedly connected to the lower surface of the inner wall of the box body 1, the rear output end of the second water pump 19 is inserted through the rear side of the inner wall of the box body 1 and is fixedly connected to the inside of the water tank 3, a third water pump 110 is fixedly connected to the upper surface of the second water pump 19, the rear input end of the third water pump 110 is inserted through the rear side of the inner wall of the box body 1 and is fixedly connected to the inside of the water tank 3, the output end of the third water pump 110 is fixedly connected to the front side of the lower surface of the wet curtain assembly 1101, and the structures on the left and right sides of the inner wall of the box body 1 are connected and mirror-imaged;

[0029] When it is needed, the motor in the fan 18 drives the fan blades to rotate, so that the outside air passes through the air inlet 2 and passes through the setting of the protective component 11 to filter and intercept the dust and dirt from the outside. At the same time, the first water pump 14 is used to pump water from the inside of the water tank 3 and enter the inside of the wet curtain plate 12 to make the water pour on the wet curtain sheet 13, and the wet curtain sheet 13 evaporates and absorbs heat and cools down once. Due to the obstruction of the L-shaped plate 16, the cooled air is concentrated at the bottom of the box body 1, and at the same time, it is passed The third water pump 110 is provided to extract the water inside the water tank 3 into the wet curtain assembly 1101. When the fan 18 is started, the air after the first cooling moves upward, and is cooled for the second time by the wet curtain assembly 1101, and is discharged through the square air outlet 4. When the excess water inside the wet curtain assembly 1101, the wet curtain plate 12, and the wet curtain sheet 13 flows out at the bottom of the box body 1 and is extracted into the water tank 3 by the second water pump 19, the effect of water recycling is achieved.

[0030] like Figure 3 - Figure 4As shown, the protection component 11 includes a metal plate 111, and the outer surface of the metal plate 111 is provided with a strip opening 113 that is connected to the left and right. The inside of the strip opening 113 is fixedly connected with a protection net 112, and the upper and lower inner walls of the strip opening 113 are provided with limiting grooves 1131, and the inside of the strip opening 113 is provided with a cleaning plate 1132, and the rear side of the cleaning plate 1132 is fixedly connected with a rubber scraper 1133, and the front side of the cleaning plate 1132 is fixedly connected with a handle 1134;

After long-term use, the surface of the protective net 112 is covered with a large amount of dust. The handle 1134 is pulled to drive the cleaning plate 1132 and the rubber scraper 1133 to scrape and clean the dust on the surface of the protective net 112 to prevent the dust from sticking to the protective net 112. The rubber scraper 1133 has a certain degree of softness, which can prevent the protective net 112 from being damaged when cleaning the dust, thereby having a protective effect.

[0032] like Figure 5 As shown, the upper end of the cleaning plate 1132 is fixedly connected with an elastic rubber block 11321, the outer surface of the elastic rubber block 11321 is slidably connected to the upper part of the limiting groove 1131, the outer surface of the cleaning plate 1132 is provided with a magnetic area 11322, the lower end of the cleaning plate 1132 is fixedly connected with a slider 11323, the lower part of the slider 11323 is movably connected with a ball bearing 11324, and the outer surfaces of the slider 11323 and the ball bearing 11324 are slidably connected to the lower part of the limiting groove 1131;

[0033] The magnetic area 11322 has an adsorption effect on the metal plate 111, so that the position of the cleaning plate 1132 is restricted. When the cleaning plate 1132 moves, the elastic rubber block 11321 and the slider 11323 slide in the limiting groove 1131 on the upper and lower inner walls of the strip opening 113 respectively. The setting of the limiting groove 1131 has a limiting effect on the cleaning plate 1132 to prevent it from falling off easily when cleaning dust. The setting of the ball 11324 in the slider 11323 reduces the friction force when moving, and has a certain degree of flexibility. The cleaning plate 1132 is made of rubber. Through the cleaning plate 1132 and The setting of the elastic rubber block 11321 facilitates the installation. During installation, the cleaning plate 1132 is placed horizontally and rotated to make the slider 11323 enter the limiting groove 1131. At this time, the cleaning plate 1132 slowly rotates from the horizontal turntable to a vertical state, thereby squeezing and contracting the cleaning plate 1132 and the elastic rubber block 11321, and making the elastic rubber block 11321 enter the limiting groove 1131 above, thereby completing the installation. At this time, the cleaning plate 1132 and the elastic rubber block 11321 return to a normal state. Conversely, when the cleaning plate 1132 is rotated from a vertical state to a horizontal state, it is squeezed and contracted, thereby facilitating the removal.

[0034] The following is a detailed description of the working principle of the dual heat dissipation structure of the air cooler.

[0035] When it is needed, the fan 18 is set to allow the outside air to enter the interior of the box 1, and the protection component 11 is set to filter and intercept the outside dust and dirt. The first water pump 14 is used to pump water into the water tank 3 and enter the wet curtain plate 12 to water the wet curtain sheet 13, and the wet curtain sheet 13 evaporates and absorbs heat and performs a primary cooling. Due to the action of the L-shaped plate 16, the cooled air is concentrated at the bottom of the box 1, and the third water pump 110 is set to transport the water inside the water tank 3 to the wet curtain assembly 1101. Due to the setting of the fan 18, the air that has been cooled once passes through the inside of the wet curtain assembly 1101 for a second cooling and is discharged through the square air outlet 4. The protection net 112 is set to filter the dust and dirt entering the box 1 from the outside air, and the cleaning plate 1132 and the rubber scraper 1133 are driven by pulling the handle 1134 to scrape and clean the dust on the surface of the protection net 112.
