Description
Technical field
The utility model relates to biochemical instrument, more particularly, relates to a kind of thermostat metal and bathes.
Background technology
The preservation of biochemical reagents and reaction need be satisfied certain temperature condition usually; It is exactly a kind ofly to carry out temperature controlled instrument for the preservation of biochemical reagents and reaction that thermostat metal is bathed, and it is widely used in the degenerative treatments of preservation and reaction, nucleic acid and the protein of the preservation of various biological samples, various enzymes, preparatory sex change that PCR reacts (PCR), electrophoresis and serum and solidifies etc.
Present thermostat metal is bathed; Form by the multiple arrangement of being close to successively from top to bottom in structure aspects; Comprise pedestal, pad, heating and cooling parts, thermal component; One side of thermal component is provided with supply unit, display floater, and the opposite side of thermal component is provided with a ventilating fan, and ventilating fan is embedded in the casing.The thermostat metal of this prior art is bathed and aspect adjustment, is had defective, mainly shows as the heat conduction lack of homogeneity, warming and cooling rate is slow.
(1) heat conduction lack of homogeneity.
Because pad is generally made of aluminum, and the coefficient of heat conduction of aluminium be merely K=237W/mK (watt/Mi Du), can not be with heat evenly diffusion rapidly, so its heat conduction uniformity is good inadequately; On the other hand; Generally there is the space in contact-making surface between pedestal, pad, heating and cooling parts, the thermal component; For example if certain parts surface is uneven, its with just can't fit fully between the parts up and down, the heat between the part face of applying passes through the transfer of air of heat conductivility difference; The heat of the part of fitting is that the heat-conducting effect of different parts will exist than big-difference so through the metal transmission of the face of mutual applying.The heat conduction that above-mentioned a variety of causes causes is inhomogeneous, makes that the preservation or the reaction condition that are positioned over the reagent of diverse location in the same pedestal are inconsistent, causes follow-up biochemical test to carry out smoothly.
(2) warming and cooling rate is slow.
Need make an explanation to the heating and cooling mode that thermostat metal is bathed here.As far as a specific cooling piece, no matter be in heating or refrigerating state, the absolute value P of its upper and lower surfaces temperature difference is constant.Prior art is exactly through cooling piece being taked different step modes, being utilized its constant temperature difference absolute value to control the heating and cooling to pedestal.As need heat up to pedestal, then, make the underlaying surface temperature of cooling piece be lower than the upper surface temperature to the energising of cooling piece forward, because the temperature difference is constant,, can make the upper surface temperature rise to target temperature so through the underlaying surface temperature that progressively raises; As need lower the temperature to pedestal, then cooling piece is oppositely switched on, make the upper surface temperature of cooling piece be lower than underlaying surface temperature, because the temperature difference is constant, through progressively reducing the upper surface temperature, can make underlaying surface temperature drop to target temperature so.
In the heating and cooling process that thermostat metal is bathed, the running of ventilating fan can help the realization of heating and cooling.Because fin contacts with cooling piece, its temperature is consistent with the underlaying surface temperature of cooling piece, when ventilating fan turns round, will make between fin and the external environment condition and form cross-ventilation, carries out heat exchange.When pedestal is heated up; Need the underlaying surface temperature of cooling piece to raise; If this moment, the temperature of cooling piece lower surface was lower than environment temperature, the running of ventilating fan can make the temperature of fin and cooling piece lower surface rise to environment temperature as early as possible so, therefore can improve intensification efficient; When pedestal is lowered the temperature; Need the underlaying surface temperature of cooling piece to reduce; If this moment, the temperature of cooling piece lower surface was higher than environment temperature, the running of ventilating fan can make the temperature of fin and cooling piece lower surface drop to environment temperature as early as possible so, therefore can improve cooling efficient.But prior art takes to install in the metal bath lateral location mode of a ventilating fan, and its heat exchanger effectiveness is not high, makes the heating and cooling efficient of pedestal lower.
Except two point defects of said temperature adjusting aspect, the metal bath of prior art also haves much room for improvement aspect ease for use.Because during the heating of the reagent in the pedestal that thermostat metal is bathed, reagent just can heat up, and produces steam; When steam runs into cold base seat lid; Just can produce a large amount of steam and condensed water, the condensate return that forms when steam can cause the pollution of reagent in the pedestal in pedestal the time; On the other hand; When opening base seat lid, the condensed water on the base seat lid can cause the waste of reagent under the marginal flow of pedestal; Simultaneously; Condensed water flows in the element of pedestal below, the element in can etching apparatus, damages circuit, make security that thermostat metal bathes with all can not get guarantee service life.
Therefore need a kind of new thermostat metal to bathe, can improve the adjustment ability, and strengthen ease for use.
