Description
Technical field:
The present invention relates to technical field of refrigeration equipment, refer in particular to a kind of can provide the circulating cooling liquid that is lower than ambient temperature directly or indirectly cool off the running in computer CPU and the portable low-temperature coolant body circulator of IC chipset.
Background technology:
More and more faster along with computer CPU of new generation and IC chipset arithmetic speed, its high temperature problem that produces in operation process also becomes and becomes increasingly conspicuous.
See shown in the accompanying drawing 1, in the existing type of cooling, have plenty of metal fin 11 and the fan 12 that adopts the cooling of air cooling pattern directly is installed on computer CPU 10 and IC chipset, the defective of this mode is: in order to reach better radiating effect, the size of metal fin 11 need be done very greatly, but can be quite limited after all on the computer motherboard for the space of placing metal fin 11, can't satisfy this requirement, this mode also can't provide the cooling effect that is lower than room temperature simultaneously.See accompanying drawing 2, shown in 3, in the existing type of cooling, also have plenty of with liquid coolant 40 and cool off computer CPU and IC chipset, it is that the refrigeration end face 21 of refrigerating sheet 20 is attached on the computer CPU, again liquid cooling appts 30 is placed on the hot junction face 22 of refrigerating sheet 20, liquid coolant 40 by liquid cooling appts 30 inside of flowing through is taken away the heat on the hot junction face 22 of refrigerating sheet 20, the circulating device of its liquid coolant 40 is seen shown in the accompanying drawing 3, it is so-called open coolant circulation unit, promptly with a water-butt 45 that liquid coolant 40 is housed, one fan 41, one water pump 42 and plastic cement proofed sleeve 43,44 form, its shortcoming is big (will effectively cooling that bucket 45 must be suitable, the volume of bucket 45 must be more than 20 liters), except taking volume, not attractive in appearance yet, because it is open, also cause water quality to be polluted easily in addition.
Accompanying drawing 4 is depicted as so-called closed coolant circulation unit, it is by liquid coolant 40 and water pump 42 are housed in the breaker 50, add a heat radiation row 52 who forms by fan 51, bending metal tubes and metal fins and form, by heat radiation row 52 heats of taking away in the liquid.Its shortcoming is: because the space is limit, these devices can't be installed in some small-sized computer chassis, and if be installed in outside the computer chassis respectively, return each section rubber water pipe 43,44,53 of computer to breaker 50 to heat radiation row 52 by computer, add the power lead 511,421,23 of fan 51, water pump 42 and refrigerating sheet 20 etc., seem and very mixed and disorderly, and water pipe 43,44,45 and circuit 511,421,23 all easily collude because of personnel's carelessness.In addition, it is exactly that the temperature of refrigerating sheet 20 cold junction faces can be when computer CPU 10 be in holding state for a long time and low excessively that this type of cooling also has a defective, cause the condensation of moisture in its ambient air and dripping phenomenon takes place, if water flows on the pcb board, with the serious consequence that is short-circuited.
Summary of the invention:
Purpose of the present invention provides a kind of portable low-temperature coolant circulating machine that can address the above problem with regard to being at the deficiencies in the prior art part.
