Embodiment

In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only for reference with the explanation usefulness, be not to be used for the utility model is limited.

See also Fig. 2 to Fig. 4, the utility model is the bifunctional temperature control equipment of a kind of tool, comprises a pedestal 1, a refrigerator 2, a current control circuit 3, a circuit overcurrent protection 4, first temperature sensor 5 and second temperature sensor 6, an overheating protection circuit 7, reaches first temperature indicator 8, second temperature indicator 9 etc.; Wherein:

Carry respectively in the both sides of pedestal 1 and to form a separation layer 13 with a room 12 between first liquid container 10 and second liquid container, 11, two

liquid containers

10,11.

Refrigerator 2 is to be located in the room 12 of pedestal 1, has a cold junction face and a hot junction face respectively, and wherein this cold junction face makes in first liquid container 10 and obtains required low temperature, and this hot junction face makes in second liquid container 11 and obtains required high temperature.

Current control circuit 3 is connected in refrigerator 2, in order to keeping the working stability of

refrigerator

2,5 ℃ the time, this current control circuit 3 promptly can be according to the family curve that sets when dispatching from the factory as design temperature, make cooler 2 play a role, make heated second liquid container 11 maintain 5 ℃ of constant temperature; Design temperature is in the time of 25 ℃, and this current control circuit 3 promptly can make cooler play a role according to the family curve that sets when dispatching from the factory, and makes heated second liquid container 11 maintain 25 ℃ of constant temperature;
