Abstract
The invention relates to a fast temperature regulating mechanism for a centrifugal machine. The fast temperature regulating mechanism comprises a rotating head, a refrigeration pipeline, a condensation fan and a compressor, wherein the rotating head is arranged on a main motor of the centrifugal machine and is positioned in a separating cavity of the centrifugal machine, the refrigeration pipeline is arranged at the outer side of the separating cavity in a winding way, and the condensation fan and the compressor are connected with the refrigeration pipeline. The fast temperature regulating mechanism for the centrifugal machine has the advantages that the current temperature is compared with the set temperature, if the current detected temperature is lower the set value, the cavity and the rotating head need to be heated for raising the temperature, the rotating head rotates at a high speed through being driven by the motor, the rotating head is in friction with air in the separating cavity, and the temperature of the separating cavity and the rotating head fast rises to the set value through generated heat; when the current temperature is higher than the set value, the temperature of the cavity and the rotating head needs to be lowered. A refrigeration system (comprising the compressor, a heat radiator and the condensation fan) starts, and the separating cavity accelerates the heat exchange due to forced convection generated through the rotation of the rotating head, so that the temperature of the separating cavity and the rotating head is fast lowered to the set value.
Description
Technical field
The fast temperature that the present invention is used under centrifuge holding state regulates, particularly a kind of centrifuge temperature rapid adjustable mechanism.
Background technology
Temperature under present centrifuge holding state controls, and generally has two kinds of control modes, pre-refrigeration mode or uncontrolled pattern.Pre-refrigeration mode is that motor and rotary head do not operate, compressor start, refrigeration system work, makes cavity and rotary head temperature reduce by the free convection of air in cavity and radiation, this mode cavity and rotary head reach temperature required chronic, and the gradient difference of cavity and rotary head temperature is very large.Under uncontrolled pattern, temperature is uncontrolled, changes with variation of ambient temperature, and the temperature of centrifuge cavity and rotary head when user uses is also different with environment temperature from temperature required deviation, may damage some and require higher sample to storage temperature.
Summary of the invention
The invention provides a kind of centrifuge temperature rapid adjustable mechanism that temperature can be made to reach the temperature range needed for use fast.
For solving the problems of the technologies described above, centrifuge temperature rapid adjustable mechanism of the present invention, comprising: rotary head, described rotary head is arranged on the mair motor of centrifuge, and described rotary head is positioned at the disengagement chamber of centrifuge; Refrigeration pipe, described refrigeration pipe winding is in the external side of described disengagement chamber; Condensation fan and compressor, described condensation fan and described compressor are connected with described refrigeration pipe.
Described centrifuge temperature rapid adjustable mechanism also comprises a control device, the temperature sensor that described control device comprises control circuit and is connected with described control circuit; Wherein said temperature sensor is arranged in described separation cavity; Described mair motor, described condensation fan and described compressor are connected with described control circuit.
Also door closure is provided with on described separation cavity top.A radiator is also provided with in described centrifuge.
Centrifuge temperature rapid adjustable mechanism of the present invention compares with the temperature of setting according to current temperature, if the temperature of current detection is lower than setting value, need to cavity and rotary head heat temperature raising, rotary head is High Rotation Speed under the drive of motor, rotary head and the windage be separated in cavity, the heat of generation makes separation cavity and rotary head rapid temperature increases to settings; If Current Temperatures is higher than setting value, just need to cavity and rotary head cooling.Refrigeration system (comprising compressor, radiator, condensation fan) starts, and be separated the forced convertion that cavity produces because of the rotation of rotary head and heat exchange is accelerated, the temperature of therefore separation cavity and rotary head drops to setting value rapidly.

Detailed description of the invention
Below in conjunction with accompanying drawing, centrifuge temperature rapid adjustable mechanism of the present invention is described in further detail.
As shown in Figure 1 and Figure 2, centrifuge temperature rapid adjustable mechanism of the present invention, comprising: rotary head 5, rotary head 5 is arranged on the mair motor 6 in separation cavity 3, rotary head 5 is High Rotation Speed under the drive of motor, and with the windage be separated in cavity, the heat of generation makes separation cavity and rotary head rapid temperature increases.
The refrigeration system be made up of condensation fan 1, radiator 2, compressor 7 and refrigeration pipe 8, makes heat exchange accelerate for the convection current strengthening being separated cavity 3, the temperature of separation cavity 3 and rotary head 5 is declined rapidly.
In addition, in the separation cavity 3 of centrifuge, be provided with temperature inductor and be connected with control circuit, for detecting the temperature be separated in cavity 3.The temperature of the temperature of current detection and setting is compared, if the temperature of current detection is lower than setting value.Start the function that is rapidly heated, make rotary head High Rotation Speed under the drive of motor; If current detection temperature is higher than setting value, start quick temperature-reducing function, refrigeration system (comprising compressor, radiator, condensation fan) starts, and is separated the forced convertion that cavity produces because of the rotation of rotary head and heat exchange is accelerated.
Centrifuge temperature rapid adjustable mechanism of the present invention compares with the temperature of setting according to current temperature, if the temperature of current detection is lower than setting value, need to cavity and rotary head heat temperature raising, rotary head is High Rotation Speed under the drive of motor, rotary head and the windage be separated in cavity, the heat of generation makes separation cavity and rotary head rapid temperature increases to settings; If Current Temperatures is higher than setting value, just need to cavity and rotary head cooling.Refrigeration system (comprising compressor, radiator, condensation fan) starts, and be separated the forced convertion that cavity produces because of the rotation of rotary head and heat exchange is accelerated, the temperature of therefore separation cavity and rotary head drops to setting value rapidly.
Below the preferred embodiment of the invention is illustrated, but the invention is not limited to embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
