The upper bottom plate and the lower bottom plate are opened with snake shaped grooves which are corresponded with each other, the shape of the red copper pipe and the resistance heater is coincident with that of the snake shaped grooves, the resistance heater and the red copper pipe are installed in the snake shaped groove in parallel. The upper bottom plate and the lower bottom plate are assembled together by the half head combined bolt, the refrigerant is introduced into the red copper pipe through the soft pipes to form a heat exchange pathway. The arrangement of the snake shaped grooves controls the temperature uniformity of the bottom plate at plus-or-minus 1 centigrade, a platinum resistance is installed at the center of the bottom plate and is used to test the temperature of the bottom plate. The utility model realizes the temperature adjustment and temperature control of the bottom plate, increases the heat conduction between the bottom plate and a work-piece, and increases the testing function of the bottom plate. The heat sink bottom plate can meet the working requirement of an experimenter to the maximum extent, lead the experiment accurate and reliable, and save time.
Description
Technical field
The utility model relates to a kind of heat sink base plate that is used for space-environment facility, belongs to the space-environment facility field.
Background technology
Space-environment facility is the equipment of virtual space vacuum and low temperature environment, base plate is the critical piece of carrying test specimen in this kind equipment, floor level is installed in heat sink inside, can only baseplate temp be changed by thermal radiation under the condition at present, be fully passive can not independent temperature control, therefore when carrying out space environment simulation test, will expend a large amount of heating and cooling time, and the uniformity of temperature-controlled precision and base plate self-temperature is not easy also to guarantee.
For improving the speed of heating and cooling, guarantee that the uniformity of temperature-controlled precision and base plate self-temperature just necessarily requires base plate that the temperature circulatory system of self is arranged, the base plate that can meet the demands is also referred to as secondary heat sink.
The utility model content
The utility model provides a kind of heat sink base plate that is used for space-environment facility, can solve the base plate that space-environment facility is installed on heat sink can not independent temperature control technique problem, the intensification that base plate self has and the facility of cooling also can be realized temperature adjusting, the thermoregulation range of base plate-70 ℃～+ 100 ℃ control accuracy and temperature uniformity all be ± 1 ℃
The purpose of this utility model is achieved through the following technical solutions.
A kind of heat sink base plate that is used for space-environment facility comprises upper plate, lower shoe, copper tube, resistance heater and half a head assembling bolt, and ancillary equipment is measured workpiece, external power source, RTD, flexible pipe and refrigerant; Upper plate and lower shoe have corresponding snake type groove and uniform screw hole, copper tube is consistent with snake type groove with the resistance heater profile, resistance heater and copper tube are contained in the snakelike tank side by side, the half a head assembling bolt assembles upper and lower bottom plate, by flexible pipe refrigerant is introduced copper tube and form heat exchange paths, resistance heater and external power source connect and compose heating source; Snake type trench pattern make the baseplate temp uniformity be controlled at ± 1 ℃, the base plate center is equipped with the temperature that RTD is used to test base plate; Measured workpiece places the upper plate top.
The refrigerant that uses in the copper tube can be alcohol, conduction oil or liquid nitrogen.Base plate adopts the LY12 aluminium sheet of thickness 10mm.The half a head assembling bolt is made with stainless steel.The front edge of upper plate also is equipped with the assembling bolt more than 18, and assembling bolt can connect thermal conductive metal plate and cover on the workpiece, and purpose is the heat conduction that increases measured workpiece and base plate.
Working method: when the workpiece on the upper plate need heat up, connect external power source, the heat that resistance heater produces conducts to upper plate and lower shoe, passes to measured workpiece by upper plate again; When the measured workpiece on the upper plate need be lowered the temperature, close external power source, connect the heat exchange paths of copper tube and flexible pipe, the heat of measured workpiece is taken away in the circulation of heat exchange paths by refrigerant, the temperature of measured workpiece is reduced; RTD can reflect the temperature conditions of base plate immediately, so that testing crew is controlled the variations in temperature of heat sink base plate.
Beneficial effect:
(1) temperature adjustment and the temperature control of base plate have been realized.
(2) heat that has increased between base plate and the workpiece is conducted.
(3) increased the test function of base plate, can satisfy experimenter's work requirements to greatest extent, made test accurately reliable, saved time
(4) baseboard material adopts aluminium sheet to save cost than normally used copper plate.
