Abstract
The utility model relates to a heat exchanger, in particular to a large heat capacity heat exchanger, which comprises an inner bag with cavity function, a pipe coil and characteristically, an insulation layer, wherein, the insulation layer and the inner bag form an enclosed space; the pipe coil is positioned in the enclosed space and forms an intervallic nesting; heat holding conducting material is filled into the enclosed space. The utility model has the advantages of that: containing the pipe coil and the heat holding conducting material in the enclosed space formed by the insulation layer and the inner bag makes the space between the pipe coil and the inner bag had high heat exchange efficiency without clinging together, thereby, during making the heat exchanger, the inner bag needs only to be nested into the pipe coil winded up in advance without clinging and winding the pipe coil on the outer wall, simplifying manufacture process and increasing production efficiency; in addition, the heat holding conducting material filled in the enclosed space formed by the insulation layer and the inner bag increases heat capacity of single pipe coil and heat exchange effect.
Description
Technical field
The utility model relates to a kind of heat exchanger, particularly a kind of heat exchanger that big thermal capacity can be provided; The utility model also relates to the refrigerated centrifuge that uses above-mentioned heat exchanger.
Background technology
Refrigerated centrifuge is a kind of biomedical sector instrument and equipment commonly used, is used for isolating from biological sample the active ingredient of needs; One high speed rotor rotated is arranged in centrifuge, and this rotor is arranged in the groove shape cavity, and this cavity has a loam cake, in normal operation, because the high speed rotation of described rotor can make the air themperature in the cavity sharply raise; Because a lot of active ingredients all are organized enzymes in the biological sample, temperature will lose activity after surpassing 40 ℃.Therefore often outside described cavity, twine refrigerating coil (as shown in Figure 1), rise for the air cooling-down in the described cavity by kind of refrigeration cycle; In order to improve heat exchange efficiency, generally can select for use relatively thinner material to make cavity, and can when twining refrigerating coil, make great efforts to make coil pipe to be close to described cavity, tend to occur cavity like this and be extruded distortion, the problem of complex manufacturing, inefficiency; Simultaneously, because simple coil pipe cold-storage and thermal storage ability is relatively poor, cooling-down effect is not satisfactory.Because also participate, and also be to pack into after processing together in the centrifuge shell when making at cavity described in the cold and hot exchange process; For the convenience of narrating, the utility model is referred to as heat exchanger with the assembly of cavity and coil pipe.Therefore can be with the above-mentioned deficiency of prior art, be summed up as that the exchanger heat capacity is little, complex manufacturing, inefficiency.
The utility model content
A purpose of the present utility model is to provide a kind of can improve that thermal capacity is big, the simple heat exchanger of production technology.
Another purpose of the present utility model is to provide a kind of refrigerated centrifuge that utilizes above-mentioned heat exchanger.
The purpose of this utility model is achieved by the following scheme:
A kind of heat exchanger, comprise inner bag and coil pipe with cavity function, it is characterized in that, described heat exchanger also comprises a heat-insulation layer, described heat-insulation layer and inner bag form an enclosure space, described coil pipe is arranged in described enclosure space, and forms the nested of gap with described inner bag, is filled with in described enclosure space and holds the thermal conductance hot material.
Described appearance thermal conductance hot material is the moving colloid of semi-fluid;
Described appearance thermal conductance hot material is an oil;
A kind of refrigerated centrifuge that uses above-mentioned heat exchanger also comprises housing, rotor, motor and control system.
The space that the utility model adopts inner bag and heat-insulation layer to form holds coil pipe and holds the thermal conductance hot material, make to be close to also between coil pipe and the inner bag heat exchange efficiency preferably can be arranged, like this when making described heat exchanger, only need to advance in the good coil pipe of described prior coiling inner bag is nested, be close to the coiling coil pipe outside the tank on the wall by force, simplified production technology, improved production efficiency; Filled in the space owing to inner bag and heat-insulation layer formation in addition and held the thermal capacity that the thermal conductance hot material has strengthened simple coil pipe, strengthened the heat exchange effect.
Description of drawings
Fig. 1 is the cross-sectional view of heat exchanger in the prior art;
Fig. 2 is the cross-sectional view of the utility model heat exchanger;
The specific embodiment
For the technical solution of the utility model better is described, the utility model is by being introduced as example with the refrigerated centrifuge that uses heat exchanger described in the utility model.
A kind of refrigerated centrifuge that uses above-mentioned heat exchanger also comprises housing, rotor, motor, control system and heat exchanger and forms other equipment that cooling and warming circulates with described heat exchanger.Heat exchanger as described in Figure 2, comprise inner bag 1, coil pipe 2 and heat-insulation layer 3 with cavity function, described heat-insulation layer 3 forms an enclosure space 4 with described inner bag 1, described coil pipe 2 is arranged in described enclosure space 4, and form the nested of gap with described inner bag 1, in described enclosure space 4, be filled with and hold thermal conductance hot material 5.Described inner bag 1 generally is " U " shape.Described appearance thermal conductance hot material 5 moves colloid for semi-fluid or is oil and analog thereof.
After adopting described heat exchanger structure, when making heat exchanger, only need the inner bag gap is nested to advance in the good coil pipe of described prior coiling, be close to the coiling coil pipe outside the tank on the wall by force, simplified production technology, improved production efficiency; Filled in the enclosure space owing to inner bag and heat-insulation layer formation in addition and held the thermal capacity that the thermal conductance hot material has strengthened simple coil pipe, strengthened the heat exchange effect, making needn't be close to also between coil pipe and the inner bag to have heat exchange efficiency preferably.
Above the utility model is by having illustrated the technical solution of the utility model with the example that is applied as of described heat exchanger on refrigerated centrifuge, but this can not be used for limiting protection domain of the present utility model; What flow through in the coil pipe as described is the medium that needs heat release, and then this heat exchanger can heat up for the environment that needs heat up.Described heat exchanger might have straight plate object and described heat-insulation layer to form enclosure space, with coil pipe parallel put into this enclosure space, and then fill and hold the thermal conductance hot material; Form the cooling and warming circulation with other equipment, for the environment that needs temperature adjustment carries out temperature adjustment.Described inner bag cross section also also has other distortion, and as forming W shape and prostrate W shape etc., corresponding coil pipe and/or heat-insulation layer also can have distortion.Therefore the change of those skilled in the art's conspicuous unsubstantiality of making according to the utility model or improve the protection domain that all should fall within the utility model claim.
