The side wall of two pieces of partition cooperation shells 1 forms cavity 3, and liquid is filled in cavity 3, is provided through exhaust outlet 4 on shell 1,
Exhaust outlet 4 is separated by partition with pcb board 2, and shell 1 is internally provided with exhaust gear 5, exhaust gear 5 use micro air pump for
Power source, the input terminal and pcb board 2 of micro air pump are located at same chamber, and the output end of micro air pump is connected to exhaust outlet 4, miniature
Air pump is located at the lower section of cavity 3, and the input terminal of micro air pump sequentially passes through the inner cavity that two pieces of partitions prolong Shen to 2 place of pcb board,
The output end of micro air pump is connected to by conduit with exhaust outlet 4, and the output end of exhaust gear 5 is connected to exhaust outlet 4, shell 1
Bottom is provided through admission gear 6, and the output end of admission gear 6 extends between two pieces of partitions, and admission gear 6 includes air inlet
Pipe 601, the bottom end of air inlet pipe 601 run through the bottom of shell 1 and are in communication with the outside, and the top of air inlet pipe 601 extends to cavity 3
Inside is simultaneously connected to one end of U-tube 602, and the other end of U-tube 602 is located under the liquid level of liquid, the highest of U-tube 602
Point is located at the top of liquid levels, and the exit of U-tube 602 is provided with baffle 10, several micropore knots are offered on baffle 10
Structure.It is avoided by setting microcellular structure so that gas be made to be divided into the lesser air-flow of multiply at the inside for entering liquid
Because discharge gas it is excessive, cause not contact with liquid sufficiently at gas center, so as to cause the effect that comes it is poor
Situation occurs, and screw thread is equipped with filter mantle 9 on the inlet end of air inlet pipe 601, and filter mantle 9 is in hollow spherical, and in sphere
Outer surface offer several filter holes, screw thread mouth is offered on filter mantle 9, the bottom end of air inlet pipe 601 extends to screw thread mouth
It is internal and be threadedly coupled by screw thread spoken language filter mantle 9, the inside of the shell 1 and two sides for being located at pcb board 2 are provided with wind

Several branch pipes are provided through, by a group pipe cooperation mostly being used cooperatively with branch pipe, so that gas be made to enter pcb board
In chamber where 2 more uniformly, to keep the cooling of pcb board 2 more uniform.And the input terminal of every branch pipe all with supervisor
72 output end connection, is responsible for 72 input terminal and is connected to by conduit with adsorbing mechanism 8, air cooling mechanism 7 passes through conduit with cavity 3
It is connected to adsorbing mechanism 8.There are two raised structures, adsorbing mechanism 8 to be located at protrusion knot for setting on the partition of 2 side of pcb board
The inside of structure, protrusion mechanism are made of two blocks of side plates and one piece of top plate, and adsorbing mechanism 8 includes placement plate 801, and placement plate 801 is in
Netted mechanism, and it is placed with silica gel absorption layer 802 in the top of placement plate 801, and fix in the top of placement plate 801
Clamping plate 803 is installed, silica gel absorption layer 802 is placed between clamping plate 803 and placement plate 801.Silica gel absorption layer is that have several
Blue silica gel particle composition, blue silica gel particle has unique water absorption character, can pass through conduit and recent machine to avoid liquid
Mechanism reach two pieces of partitions outside, thus caused by pcb board short circuit situation.Blue silica gel particle after saturation can simultaneously
Becoming red can remind people to replace in time.
At work, pcb board is because the presence of resistance converts electrical energy into interior energy, thus elevate the temperature, but due to
Micro air pump works, and when micro air pump is worked, the air inside shell 1 can be discharged, gas can pass through conduit
The inside of micro air pump is entered, is then discharged from exhaust outlet 4 by the cooperation of the exhaust outlet and conduit of micro air pump, and
By micro air pump due to the limitation of partition, cause micro air pump only can be by 2 place space of pcb board when being worked
Interior gas extraction, the gas of extraction is to absorb the high-temperature gas of thermal energy on pcb board, and after high-temperature gas is extracted,
Due to the presence of atmospheric pressure, external air can enter the inside of shell 1 by recent mechanism 6, external air by into
The import of tracheae enters the inside of shell 1, and external air can enter U-tube 602 by the exhaust outlet of air inlet pipe
Inside, the special shape design of U-tube 602 and is located under the liquid level of liquid due to the other end of U-tube 602, thus
Make outside air in the inner cavity for entering shell 1, the immersion by liquid must be needed, so that the dust in air be made to adhere to
In liquid, without being flowed with air, and due to, the highest point of U-tube 602 is located at the top of liquid levels,
Therefore there is no liquid reaches the outside of shell 1 by the cooperation of U-tube 602 and air inlet pipe 601.Pass through U-tube in gas
After 602 discharges, gas can be risen on liquid level by liquid, enter the inside of cavity 3, and pass through adsorbing mechanism later
8 enter the inside of air cooling mechanism 7, are discharged by air cooling mechanism 7, in the cavity that external air enters shell 1 after, outside
The inside of shell 1 and the chamber for being located at 2 place of pcb board carry out cooling and carry out the temperature-fall period recycled, to guarantee pcb board
Normal work.
In summary: the present invention is compared by the cooperation of setting exhaust gear, admission gear, air cooling mechanism and liquid
Existing information acquisition terminal, using unique radiating mode, during carrying out air exchange, dust is entering shell
Inside after, can be adhered in liquid, and can not be attached on pcb board, thus the case where avoiding pcb board aging circuit appearance.
The present invention is by two pieces of partitions of setting simultaneously, so that cavity is formed, since there are liquid in cavity, first in air
When entering interior of shell dust and particle that may be present in air can be adsorbed, dust is avoided by liquid, liquid
The outer surface of pcb board is attached to particle, and at the same time, air is by liquid later because interior in liquid evaporation draw air
Can, so that making the temperature of air reduces, to keep cooling effect more preferable.
And the present invention is by being arranged adsorbing mechanism, and silica gel absorption layer is that have several blue silica gel particles in adsorbing mechanism
Composition, blue silica gel particle has unique water absorption character, can reach two pieces by conduit and recent machine mechanism to avoid liquid
The outside of partition, thus caused by pcb board short circuit situation.Blue silica gel particle will become red after saturation simultaneously to mention
Awake people replace in time.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
