Abstract
The utility model relates to a high efficiency combination type radiator, comprising two cooling plates provided with water communicating hole channels and four semiconductor refrigerators arranged between two cooling plates. The utility model belongs to the combination technology of the cooling plate technology, the heat convection and the semiconductor refrigeration technology. The radiator is high and adjustable in heat exchanger capability. The utility model can ensure the temperature of the reference points of the pipe casing of a measured power transistor to stabilize at the preassigned number value.
Description
Technical field is heat conduction reinforced and control device under the utility model.
Quoted passage of the present utility model is:
1) Yi Benjian, QR-3 transistor npn npn transient thermal resistance tester development report (Beijing Radio Instruments Factory).
2) R.C.Chu(Zhu Zhao is all), the heat exchange of microelectronic device factory, Yu Chuanze, 1974.
The efficient combined-type radiator is in order to measure the steady state heat resistance of power transistor, is used for the device of stable crystal shell reference point temperature.The transistor steady state heat resistance instrument of present domestic usefulness is measured the steady state heat resistance of power transistor, adopts thermostat to stablize the reference point temperature of shell more.But this device can not make the reference point temperature stabilization of shell at the set-point by the national standard requirement.And often because power changes the also change thereupon of reference point temperature, and it is longer to obtain equilibrium temperature operating mode required time, generally need temperature just can settle out more than several hours.The transistorized steady state heat resistance of external at present mensuration adopts boiling heat transfer device to come the temperature of stable crystal shell reference point, and this boiling heat transfer device can only be with temperature stabilization near the boiling point of used liquid.So narrow range of equilibrium temperature.
The purpose that the present utility model is created is: because said apparatus does not satisfy the needs of the steady state heat resistance of measuring power transistor, so need a kind of efficient combined-type radiator of innovation and creation, it is the cold drawing technology, the combination of heat convection and cooling technique of semiconductor, its exchange capability of heat is high and adjustable, and the temperature stabilization that can guarantee reference point on the shell is at preassigned numerical value.
The purpose of this utility model is realized by following technology.
The efficient combined-type radiator, it is by last cold drawing (1), following cold drawing (2) and being positioned at, four semiconductor coolers (3) between following cold drawing are formed.Last cold drawing (1) is provided with two water flowing ducts (4), by water main heat is taken away, and plays main thermolysis.Following cold drawing (2) is by water inlet pipe (5), and outlet pipe (6) is communicated with formation with two horizontal water flowing ducts (7) and plural vertical water flowing duct (8), and it takes away the heat of refrigerator hot junction (9), to improve freezing capacity and exchange capability of heat.Adjust the electric current of discharge and refrigerator, can change the exchange capability of heat of radiator, and then adjust reference point temperature on the shell.
Accompanying drawing
Fig. 1. the efficient combined-type radiator is faced structural representation.
Fig. 2. the efficient combined-type radiator is looked squarely structural representation.
Below in conjunction with description of drawings detailed structure of the present utility model.
The efficient combined-type radiator, but it is by the cold drawing of two water flowings cooling be clipped in two semiconductor coolers (3) between the cold drawing and form.The last cold drawing (1) that has two big water flowing ducts (4) near thermal source can reach 10 with the hot-fluid degree
5The above central heat source of W/M scatters and plays main thermolysis.Following cold drawing (2) is provided with water inlet pipe (5), and outlet pipe (6) also is communicated with horizontal water flowing duct (7), and laterally water flowing duct (7) with two, plural vertical water flowing duct (8) is communicated with.Last, with the cold drawing center symmetrical 4 block semiconductor refrigerators (3) are set between the following cold drawing.Power transistor (10) is positioned on the cold drawing (1), and its pin hole (11) is right against the gap between the semiconductor cooler in twos.Reference point temperature thermocouple measurement on tested shell and last cold drawing (1) contact surface, thermal cross contacts pressure with tested shell surface and adjusts with spring, makes all to keep good thermo-contact between each contact-making surface.The working medium of cooling usefulness also can be used other fluids beyond dewatering, as transformer oil or the like.
When measuring the power transistor steady state heat resistance, two of last cold drawing (1) feed water than macropore (4) heat that power transistor produces are scattered, its heat-sinking capability is finished by the flow that changes channel water, play main thermolysis, and semiconductor cooler (3) and the following cold drawing that has a plurality of connected pore channels play the fine tuning effect of auxiliary heat dissipation ability.The cold junction of semiconductor cooler contacts with last cold drawing, and its hot junction (9) contact with following cold drawing, adopts to change to feed the flow of cold drawing (2) duct water down, and the heat in semiconductor cooler (3) hot junction (9) is taken away, and improves freezing capacity and exchange capability of heat.By last, the radiating mode of following cold drawing water flowing duct and semiconductor cooler combination, can guarantee that radiator has enough heat-sinking capabilities, easy to adjust again, make the reference point temperature stabilization at predetermined value, and can be in very wide temperature range the temperature of stable reference point, testing a used time of operating mode shortens greatly, shortens to tens minutes by original several hours.Increase work efficiency greatly.
Claims (2)
1, a kind of efficient combined-type radiator, it is characterized in that it is by last cold drawing (1), following cold drawing (2) and be positioned at up and down four semiconductor coolers (3) between cold drawing and form, two water flowing ducts (4) are set on the last cold drawing (1), following cold drawing (2) is by water inlet pipe (5), outlet pipe (6) and two horizontal water flowing ducts (7) and two, plural vertical water flowing duct (8) is communicated with formation.
