Description

A kind of semiconductor cooler refrigeration performance monitor station

Technical field

The utility model relates to semiconductor cooler and manufactures field, especially a kind of semiconductor cooler refrigeration performance monitor station.

Background technology

Semiconductor cooler claims again thermoelectric refrigerating unit or thermoelectric refrigerator, to utilize extraordinary semi-conductor thermoelectric material composition P-N knot, logical upper direct current, the object that can reach refrigeration and heat at two of a semiconductor cooler end face, the safety having due to semiconductor cooler, environmental protection, the features such as the life-span is long, utilize the use occasion of semiconductor cooler refrigeration a lot of both at home and abroad, for improving refrigeration work consumption, reach industrial applications, existing semiconductor cooler, all by tens, up to a hundred P-N knot composition thermoelectric piles, tens, the thermoelectric pile of up to a hundred P-N knot compositions just respectively has tens, up to a hundred P types and N-type semiconductor particle, in the time manufacturing semiconductor cooler, its technological process is long, operation is many and complicated, technical requirement is high, not only require operator to there is suitable technical capability, have again rigorous, absorbed spirit, even but like this, product percent of pass also can not reach absolutely, at present, user is very high to semiconductor cooler technical property requirements, require harshly product percent of pass to reach 3/1000ths level, this has proposed very large technostress to semiconductor cooler manufacturing enterprise, originally the factory inspection of enterprise's semiconductor cooler is to adopt sampling observation, and be to detect the technical data of simulating in computer under use state, thereby judge that whether product is qualified, product is easily undetected, analog detection data can not really reflect the quality of product, so often do not reach user's requirement, have the situation of the reparation of returning goods to occur when product.

Summary of the invention

In order to address the deficiencies of the prior art, the utility model provides a kind of semiconductor cooler refrigeration performance monitor station, changes sampling observation for full inspection, change analog detection is the refrigeration performance detection under virtual voltage, current condition, can reach fast detecting, detect effect directly perceived, guarantee qualification rate.

The utility model solves the technical scheme that its technical matters adopts: a kind of semiconductor cooler refrigeration performance monitor station, comprises micro pump, test board, worktable, casing, DC ammeter, switch, AC-DC converter, D.C. voltmeter, p-wire, water tank, small hose; Described casing is located on worktable, in casing, be provided with AC-DC converter, on the front panel of casing, be embedded with D.C. voltmeter, switch and several DC ammeter in parallel, from several DC ammeter and power cathode, parallel connection picks out some to p-wire, stretches out from the front panel below of casing, on every test the end of a thread, is connected to a wire clamp, electrode line connects red wire clamp, and negative line connects black wire clamp; Described micro pump, water tank are located in worktable, and described test board is arranged on work top, and test board is made hollow body, and test board two ends are provided with intake-outlet, are communicated with respectively with micro pump and water tank; Separate a small hose from the rising pipe of micro pump, be placed on worktable.

Accompanying drawing explanation

Fig. 1 is a kind of semiconductor cooler refrigeration performance of the utility model monitor station structural representation.

In Fig. 1,1, water pump 2, test board, 3, worktable, 4, casing, 5, DC ammeter, 6, switch, 7, AC-DC converter, 8, D.C. voltmeter, 9, p-wire, 10, water tank, 11, small hose.

Embodiment

Below in conjunction with accompanying drawing 1, a kind of semiconductor cooler refrigeration performance of the utility model monitor station is described further.

A kind of semiconductor cooler refrigeration performance monitor station shown in Fig. 1, is made up of micro pump 1,

test board

2,3 of work, casing 4, DC ammeter 5, switch 6, AC-DC converter 7, D.C. voltmeter 8, p-wire 9, water tank 10 and small hose 11, described casing 4 and worktable 3 adopt sheet iron to make, casing 4 is placed on worktable 3, in casing 4, be provided with AC-DC converter 7, external 220 volts of alternating currents are transformed into 12 volts of direct currents, on the front panel of casing 4, be embedded with a

D.C. voltmeter

5, 6 and 9 DC ammeter in parallel 5 of switch, DC ammeter 5 maximum ranges are 10 amperes, from 9 DC ammeter 5 and power cathode, parallel connection picks out 9 pairs of p-wires 9, stretch out from the front panel below of casing 4, on 9 of every p-wires, be connected to a wire clamp, electrode line connects red wire clamp, negative line connects black wire clamp, described micro pump 1, water tank 10 are located in worktable 3, described test board 2 adopts thermal diffusivity, and good aluminium is made hollow body, is arranged on worktable 3 table tops, and test board 2 one side upward grinds smooth, its two ends are provided with intake-outlet, are communicated with respectively with micro pump 1 and water tank 10, separate a small hose 11 from the rising pipe of micro pump 1, be placed in 3 of worktable upper, worktable 3 edges are a little more than table top, in order to avoid ponding overflows worktable 3, table top is provided with several small openings, can make ponding drain in water tank 10.
