On basis based on above-mentioned design tubing type liquid heat abstractor technical scheme, the present invention also devises following optimal technical scheme further: for fan 6, further design adopts brushless motor fan, make tubing type liquid heat abstractor designed by the present invention in practical work process, quiet work can be realized, both ensure that designed tubing type liquid heat abstractor had efficient heat sinking function, can ensure that again its course of work does not produce noise effect to surrounding environment, embody the human oriented design in design process; Also have for each designed on the surface air vent hole 9 of outer tube 1, each air vent hole 9 of further design is equally spaced to be each other evenly distributed on surperficial one week of outer tube 1, temperature difference between heat dissipation region can be treated set by gap environment and outer tube 1 between outer tube 1, interior pipe 2, and under the acting in conjunction of fan 6, in further raising outer tube 1 external environment condition, hot-air flows to the flow efficiency of outer tube 1 inside through the surperficial each air vent hole 9 of outer tube 1, and then effectively improves the heat radiation operating efficiency of designed tubing type liquid heat abstractor; And for control module 3, design adopts single-chip microcomputer further, and can be applicable to the expansion demand of later stage for designed tubing type liquid heat abstractor on the one hand, on the other hand, succinct control architecture mode can be convenient to the maintenance in later stage; Moreover, for power supply 4, design adopts external power supply further, effectively can ensure that designed tubing type liquid heat abstractor is in real work radiation processes, the stability of power taking, electricity consumption, and then the radiating effect that effectively can ensure tubing type liquid heat abstractor reality.
The present invention devises tubing type liquid heat abstractor in the middle of actual application, specifically comprise outer tube 1, interior pipe 2, single-chip microcomputer, and the external power supply be connected with single-chip microcomputer respectively, temperature sensor 5, brushless motor fan, wherein, external power supply is respectively temperature sensor 5 through single-chip microcomputer, brushless motor fan powers; Outer tube 1 adopts heat-barrier material to make, and interior pipe 2 adopts Heat Conduction Material to make; Wherein one end of outer tube 1 is closed, and the other end opens wide, and on outer tube 1, the surface of blind end arranges the first through hole 7, and the internal diameter of internal diameter and the second through hole 8 that side outer tube 1 being positioned at open end arranges the second through hole 8, first through hole 7 all adapts with the external diameter of interior pipe 2; The external diameter of interior pipe 2 is less than the internal diameter of outer tube 1, wherein one end of interior pipe 2 connects water supply line, the other end of interior pipe 2 is passed the first through hole 7 on outer tube 1 blind end surface by outer tube 1 outside, enter outer tube 1 inner, and extend out to outer tube 1 outside along outer tube 1 inner track through the second through hole 8 on outer tube 1 and be connected with collecting-tank, and the axis of the axis and outer tube 1 that interior pipe 2 are positioned at the part of outer tube 1 inside coincides; Outer tube 1 surface arranges at least one air vent hole 9, and it is inner and outside that each air vent hole 9 connects outer tube 1 respectively, and each air vent hole 9 is equally spaced to be each other evenly distributed on surperficial one week of outer tube 1; Temperature sensor 5 is arranged at the outer surface of outer tube 1; The external diameter of brushless motor fan blade and the internal diameter of outer tube 1 adapt, and brushless motor fan is arranged on the open end of outer tube 1, and the working air current of brushless motor fan points to the outside of outer tube 1 by outer tube 1 inside.In practical application, being arranged at by tubing type liquid heat abstractor designed by the present invention treats in the middle of heat dissipation region, especially its middle external tube 1 is arranged at and treats heat dissipation region, interior pipe 2 connects one end of feed pipe, fetch water by feed pipe, and flow along interior pipe 2, the other end finally by interior pipe 2 enters in collecting-tank, because outer tube 1 adopts heat-barrier material to make, interior pipe 2 adopts Heat Conduction Material to make, the external diameter of interior pipe 2 is less than the internal diameter of outer tube 1, and the axis of the axis and outer tube 1 that interior pipe 2 are positioned at the part of outer tube 1 inside coincides, therefore, outer tube 1 place is when the temperature of heat dissipation region is higher, the interior tube-surface that then relative temperature is lower will and outer tube 1 perimeter between formation temperature poor, then the hot-air of heat dissipation region is treated at outer tube 1 place, the gap area between outer tube 1 and interior pipe 2 will be flowed into through each air vent hole 9 set by outer tube 1 surface, and contact with interior pipe 2 surface, now just lower the temperature for the hot-air flowing into gap area by interior pipe 2, effective reduction is finally through the temperature of outer tube 1 open end externally environment heat extraction air, reduce the impact on ambient temperature, what carry out with said process is simultaneously, be arranged at temperature sensor 5 real-time working on outer tube 1 surface, the temperature detection result in heat dissipation region is treated at acquisition outer tube 1 place, and in real time this temperature detection result is uploaded in the middle of single-chip microcomputer, single-chip microcomputer receives this temperature detection result and analyzes, and make corresponding further operation according to analysis result, wherein, when temperature detection result is less than or equal to preset temperature threshold value, then single-chip microcomputer does not do any further operation, by means of only liquid flow in interior pipe 2, the temperature that interior pipe 2 is relatively low and the hot-air entered in the environment of gap carry out cold and hot convection current, and nature discharges with in outer tube 1 open end externally environment, when temperature detection result is greater than preset temperature threshold value, the brushless motor fan that then single-chip microcomputer controls to be attached thereto immediately is started working, because the working air current of brushless motor fan is by the inner outside pointing to outer tube 1 of outer tube 1, therefore, under the work of brushless motor fan, hot-air in heat dissipation region set by outer tube 1 can accelerate to enter in the environment of gap by the surperficial air vent hole 9 of outer tube 1, first contact with interior pipe 2 surface subsequently and lower the temperature, subsequently again under the work of brushless motor fan, accelerate to flow to the direction of outer tube 1 open end, and then be expelled in the middle of external environment condition, when reduction affects for ambient temperature, effectively improve the heat radiation operating efficiency for heat dissipation region described in outer tube 1, in the process adopting brushless motor fan work, the temperature sensor 5 still real-time working of real-time working, when temperature detection result that single-chip microcomputer obtains is greater than preset temperature threshold value, then single-chip microcomputer does not do any further operation, keeps brushless motor fan to work on, when temperature detection result that single-chip microcomputer obtains is less than or equal to preset temperature threshold value, then single-chip microcomputer controls brushless motor fan immediately and quits work, and the cold and hot convection current in adopting between pipe 2, outer tube 1 continues to treat that heat dissipation region carries out heat discharging operation set by outer tube 1.
By reference to the accompanying drawings embodiments of the present invention are explained in detail above, but the present invention is not limited to above-mentioned execution mode, in the ken that those of ordinary skill in the art possess, can also makes a variety of changes under the prerequisite not departing from present inventive concept.
