Description
The utility model relates to a kind of heat-exchange device, relates to a kind of heating radiator of computer microwafer or rather.
Microwafer refrigeration formula heating radiator is meant the device that the cooling effect that utilizes thermoelectric effect cooling idol (Thermoelectric-Cooler) to be produced assists microwafer to dispel the heat.Commercially available this kind of product is divided into to be had the monitoring temperature circuit and not to have two kinds in monitoring temperature circuit, if general microwafer refrigeration formula heating radiator is no supervisory circuit, because of the cooling effectiveness and the microwafer temperature imbalance of thermoelectric effect cooling idol, not that can't to lower the temperature be exactly that temperature is crossed low and the dew that condenses.
Computer microwafer refrigeration formula heating radiator shown in Figure 1, A is general traditional heat radiator, B is a small-sized concealed P.e.c. PC plate and has thermistor, can monitor the temperature of heat radiator A at any time, C is a general space industry thermoelectric-cooled idol commonly used, its effect is energising work when computer microwafer temperature surpasses 35 ℃, temperature during less than 35 ℃ outage turn-off.And in concrete operations, when computer microwafer temperature surpasses 35 ℃ (being actually the temperature of heat radiator), PC plate circuit working, thermoelectric-cooled idol C becomes a hot active member, constantly pump heat to the hot joining face from the cold joint face that is with the surface of contact of wafer, reach the effect of cooling wafer.But since the thermistor of this product be device on heat radiator, when PC plate circuit working, the thermoelectric-cooled idol begins to help the wafer cooling, this moment, the heatsink temperature of thermoelectric-cooled idol hot joining face top can continue to rise; Again because the thermoelectric-cooled idol can produce about 65 ℃ " the no-load temperature difference ", so the temperature that records when thermistor is lower than 35 ℃, that is to say that thermoelectric-cooled idol hot joining face is that heatsink temperature is lower than 35 ℃, when reaching the condition of PC plate circuit shutoff, the surface of contact temperature of thermoelectric-cooled idol cold joint face that is computer microwafer is lower than 15 ℃ for a long time, the water phenomenon causes the wafer short circuit and cause with fixed attention, even damage, and if want wafer not coagulate water, then thermoelectric-cooled idol cold joint surface temperature need maintain and be lower than in 6 ℃～10 ℃ of the environment temperatures, thermoelectric-cooled idol hot joining face is that heat radiator A temperature then is higher than 35 ℃ forever like this, the PC circuit board is turn-offed, so properties of product are contradiction basically.
The purpose of this utility model is that the refrigeration formula heat spreader structures to the computer microwafer makes improvements, the parameter that the temperature monitoring element is recorded is real computer microwafer surface temperature, offer supervisory circuit again, so that control the output of thermoelectric effect cooling idol at any time linearly, obtain stable design temperature.
The utility model improves the refrigeration formula heating radiator of the computer microwafer of structure, comprise the monitoring temperature circuit of fan, heat radiator, thermoelectric effect cooling idol, thermoelectric effect cooling idol and provide the thermal sensing element of temperature parameter, it is characterized in that: also comprise the thin metal conducting strip that is clamped between described thermoelectric effect cooling idol and computer microwafer to the monitoring temperature circuit; Described thermal sensing element is adjacent on the L type catch that is installed in described thin metal conducting strip side; Also comprise one group with described heat radiator, thermoelectric effect cooling idol, thin metal conducting strip and computer microwafer up and down order be adjacent to fixing Jiong type fastening spring sheet, described fan is fixed on the fastening spring sheet above the heat radiator.
Thermoelectric effect cooling idol can see through the temperature cooling of thin metal conducting strip with microwafer, medial temperature after thermoelectric effect cooling idol and the microwafer effect conducts to the two side via metal conducting strip, at any time monitor by the thermal sensing element that is adjacent on the side conducting strip, measured temperature parameter can be guaranteed the real surface temperature for microwafer, the monitoring temperature circuit can be controlled the output of thermoelectric effect cooling idol in view of the above at any time linearly, obtains stable design temperature.
Further specify technology of the present utility model below in conjunction with the embodiment accompanying drawing.
