Detailed description of the invention
First, refer to shown in Fig. 1, key diagram of the present invention, after the temperature that first user performs required for setting on implementation controller 10, electromagnetic switch valve group 21 will be driven, to be opened according to temperature requirements by electromagnetic switch valve group 21 or close multichannel refrigerant pipeline 20, and control open the cold medium flux of refrigerant pipeline, refrigerant now after controlling flow flows to cooling system 4 via capillary group 22, can reach the object making cooling system 4 perform high temperature or low temperature.
Secondly, refer to shown in Fig. 2, schematic flow sheet of the present invention, the method for convertible refrigerant evaporation flow of the present invention and control refrigerant passage had three stages:
(1) set the stage 1: according to various electronic building brick (chip) testing requirement, perform high-temperature area or low-temperature region operation in implementation controller setting.
(2) stage 2 is controlled: implementation controller, according to set temperature, controls the different keying of passage refrigerant pipe, the passage of different flow via electromagnetic switch valve.
(3) operation phase 3: by controlling the refrigerant of different flow and passage, in variant corresponding site evaporative cooling, can make to reach when performing the direct contact chip of refrigerating head, any high temperature dot set in temperature range or low warm spot, use the effect test operation performing chip.
Secondly, refer to Fig. 3, be embodiments of the invention figure, when user sets its required high temperature on implementation controller 10, very or up to more than 100 DEG C of high temperature time, namely this implementation controller 10 drives electromagnetic switch valve 213, opens and performs the refrigerant pipeline 203 of high temperature, guides that appropriate refrigerant evaporation containing high temperature is enable reaches thermostatic effect via capillary 223.Drive electromagnetic switch valve 211 again simultaneously, another unlatching refrigerant pipeline 201, refrigerant is directed at the in good time evaporative cooling of nearly compressor 432 suction inlet by capillary 221, in order to reduce the high-temperature gas refluxed by refrigerating head 41, high-temperature gas is not made directly to be back to compressor 42, avoid high-temperature gas to burn compressor 42, guarantee that compressor 42 can run well.
Refrigerant return pipe 43 between another refrigerating head 41 to compressor 42 was the low temperature reflux pipe after evaporation originally, one layer of heat preservation material must be coated to keep evaporating the cold degree of refrigerant of rear backflow, in order to cooling compressor 42, but when performing high temperature test operation, refrigerant return pipe 43 between refrigerating head 41 to compressor 42, the refrigerant of its backflow becomes very high temperature gas, when temperature is too high, the thermal insulating material that refrigerant return pipe 43 is coated to easily is burnt, so that the heat insulation effect affected during follow-up execution low temp operation, so time this implementation controller 10 can drive electromagnetic switch valve 212 again, open refrigerant pipeline 202, refrigerant is imported in the front tube 431 of refrigerant return pipe 43 by capillary 222, carry out evaporative cooling to guarantee that this coating thermal insulating material is not burnt by high-temperature gas, low-temperature insulation effect is avoided to detract, the requirement of extremely low warm spot cannot be reached in time performing low temp operation.
Then, please still continue to consult Fig. 3, when for changing temperature requirements, on implementation controller 10, its demand of change setting is low warm spot to user, the instant corresponding electromagnetic switch valve 213 that drives of this implementation controller 10 closes high temperature refrigerant pipeline 203, another driving electromagnetic switch valve 214 opens a wherein low temperature refrigerant pipeline 204, refrigerant is guided via capillary 224 and enters sweat cooling in refrigerating head 31, in time now completing because of just execution high-temperature operation, refrigerating head 41 stores the high remaining temperature had up to more than 100 DEG C, in order to the temperature that can decline rapidly, therefore electromagnetic switch valve 215 can be driven again to open the refrigerant pipeline 205 of another assisted cryogenic simultaneously, to increase refrigerant evaporation flow, reach fast cooling and improve cooling load ability.
Another the present invention can utilize expansion valve to replace capillary group 22, cold medium flux is controlled by the keying of this expansion valve, when after implementation controller 10 design temperature, control the keying of expansion valve via electromagnetic switch valve group 21, reach and control cold medium flux and the effect that can be rapidly heated or lower the temperature.Hand expansion valve, thermal expansion valve or electric expansion valve etc. can be used all can to reach above-mentioned effect as expansion valve.
Therefore; by convertible refrigerant evaporation flow of the present invention and the method controlling refrigerant passage; system utilizes implementation controller and electromagnetic switch valve to control flow and the refrigerant passage of the refrigerant pipeline of different passage; the high-temperature operation of the direct contact chip mode of the cooling system of tool two phase change execution refrigerating head, low temp operation, thermostatic control can not only be made; the temperature of reflux gas can be reduced again; the protection compressor of cooling system and the thermal insulating material of refrigerant return pipe outer rim; operating personnel more can be protected not scalded by high temperature when high-temperature operation, in fact there is suitable progressive.
