Description
Technical field
The utility model belongs to the refrigeration temperature regulating device of Biochemical Analyzer.
Background technology
The refrigeration temperature regulating device of Biochemical Analyzer is mainly with compression and absorption cooperation temperature relay mode and freezes at present, and cold-producing medium generally all uses fluorine Lyons, not environmental protection.Because process of refrigerastion uses compressor, noise is bigger during work, uses temperature relay temperature control error big in addition, need change temperature relay if change control temperature, and underaction operates.
Summary of the invention
The utility model provides a kind of refrigeration temperature control solution, not environmental protection when freezing to solve conventional compression and absorption cooperation temperature relay, and noise is big, and the temperature control error is big, changes the inflexible problem of control temperature.The technical scheme that the utility model is taked is: water inlet pipe is connected with the water inlet of conductor cold-making block group, the water-cooled piece is fixedlyed connected with the semiconductor refrigerating piece, fin is fixedlyed connected with semiconductor refrigerating piece opposite side, the fixedly connected fan of the front end of this fin, the delivery port of this conductor cold-making block group is connected with water storage box by pipeline, water storage box is connected with water pump by pipeline, water pump is connected with outlet pipe, control circuit board is connected with conductor cold-making block group with water storage box respectively, fixedly connected float and temperature sensor in this water storage box.Operation principle is, control circuit board is used to control electric part work, and fluid temperature and semiconductor refrigerating piece current value in the display system are got through pump then through the liquid inflow water storage box that semiconductor refrigerating partly freezes, and circulate in refrigeration system.
The utility model advantage is novel structure, uses semiconductor refrigerating, has the advantage of clean environment firendly.Owing to do not use compressor so lower than traditional approach noise.The temperature control aspect is the serviceability temperature relay not, and the serviceability temperature precision is ± 0.5 ℃ temperature sensor 18B20 and integrated circuit carry out temperature control, compares with traditional temperature relay control mode that to have the temperature control error little, changes control temperature advantage flexibly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model conductor cold-making block group.
The specific embodiment
Workflow is when the water storage box water level is lower than float, and the electric control system prompting adds water, otherwise does not work; When the water storage box water level was higher than float, system started working, and temperature sensor 18b20 passes to control circuit board with temperature data, when temperature is requiring in the interval, opened 24 seconds every 120 seconds water pumps, made that liquid carries out heat exchange in the system.When temperature is higher than ceiling temperature, water pump is opened, and refrigeration system starts, and semiconductor refrigerating partly begins refrigeration, and when temperature is lower than lower limit temperature, refrigeration system stops refrigeration.
