Abstract
The invention relates to a constant-temperature temperature-control test box. The constant-temperature temperature-control test box is structurally characterized in that an insulating baffle is arranged in the middle of a box body to divide the box body into a constant-temperature region and a work region; polystyrene insulating plates are stuck on four sides, the roof and the bottom of the constant-temperature region; a polystyrene insulating plate is stuck on the roof of the work region; the insulating baffle is provided with an air inlet and an air outlet which are isolated by an L-shaped insulating plate which is connected with the insulating baffle; a fan is installed on the short edge of the L-shaped insulating plate and opposite to the air inlet of the constant-temperature region, and the air outlet is equipped with a warmer; and an intelligent temperature controller, the fan, the warmer, a solid relay and a temperature sensor are connected through lead wires, respectively. By utilizing an air cooling structure, the air flow can be normally circulated in the constant-temperature region and the work region, and thus uniform and stable temperature is ensured.
Description
Technical field
The present invention relates to a kind of constant-temperature temperature-control chamber, for test specimen provides stationary temperature (0 ℃ to-18 ℃) environment.
Background technology
Frozen soil is that the tool temperature is less than or equal to zero degree, and contains the soil body or the rock mass of ice.The all marked changes of the physico-mechanical properties of frozen soil or thermal property with variation of temperature; Be that frozen soil is very responsive to temperature, therefore, temperature is a most important underlying parameter in the cyopedology; In frozen soil experiment, sample temperature constant is the important step in the cyopedology.
Summary of the invention
Along with frozen soil experiment to the accurate requirement of temperature, the object of the invention aims to provide the constant-temperature temperature-control chamber that a kind of frozen soil sample is used.For a large amount of test specimens provide the stationary temperature environment.
The objective of the invention is to realize through following technical scheme:
A kind of temperature control Homothermal Proof Box comprises intelligent temperature controller, polystyrene heat-preservation material, fan, well heater, solid-state relay, temperature sensor, air inlet and air outlet.Be equipped with an insulation baffle plate in the middle of the casing, casing is divided into flat-temperature zone and workspace.Reach around the flat-temperature zone upward to push up to go to the bottom and post polystyrene thermal insulation plate; Polystyrene thermal insulation plate is posted on the top on the workspace.Have air inlet and air outlet on the insulation baffle plate, " L " shape warming plate that links to each other with the insulation baffle plate is isolated air inlet and air outlet, and fan is installed on the minor face of " L " shape warming plate, and is relative with the flat-temperature zone air inlet, and warmer is equipped with at the air outlet place; With lead intelligent temperature controller, fan, warmer, solid-state relay and temperature sensor are connected respectively.
The beneficial effect of advantage of the present invention and generation is:
1, on the casing intelligent temperature controller is arranged, can select steady temperature as required, 0 ℃ to the scope of-18 ℃ of negative temperatures, can keep box house flat-temperature zone temperature stabilization;
2, adopt air-cooled structure, appropriate design air channel and air quantity make air-flow guarantee that the temperature inside the box is all even stable in flat-temperature zone and workspace circulation;
3, low-power consumption is practiced thrift 80% energy than tradition with low temperature cryostat constant temperature, and efficient improves more than 5 times.

Embodiment
Below, in conjunction with accompanying drawing, the present invention is further described again:
Like Fig. 2-shown in Figure 6, a kind of temperature control Homothermal Proof Box is to form with the transformation of the way of common electrical refrigerator-freezer, comprises HPD-6219 intelligent temperature controller 1, polystyrene thermal insulation plate 2, fan 3, well heater 4, solid-state relay 5, temperature sensor 6, air inlet A and air outlet B.Intelligent temperature controller 1 model is HPD-6219, embeds on the cover plate of casing.One insulation baffle plate 7 is arranged in the middle of the casing, casing is divided into flat-temperature zone and workspace.The left side of chamber is the flat-temperature zone, reaches around the flat-temperature zone upward to push up to go to the bottom to post polystyrene thermal insulation plate 2; The chamber right side is the workspace, and polystyrene thermal insulation plate 2 is posted on the top on the workspace.Insulation baffle plate 7 is provided with air inlet A and air outlet B; " L " shape warming plate that links to each other with insulation baffle plate 7 is isolated air inlet A and air outlet B; Fan 3 is installed on the minor face of " L " shape warming plate; Air inlet A is relative with the flat-temperature zone, and the box body wall middle baffle plate is equipped with well heater 4 in the air outlet place in the flat-temperature zone; With lead intelligent temperature controller 1, fan 3, well heater 4, solid-state relay 5 and temperature sensor 6 are connected (see figure 7) respectively.
The ice box refrigeration, fan 3 is blown into the flat-temperature zone with cold airflow from air inlet A, and the cold airflow that gets into the flat-temperature zone is got back to the workspace through 4 heating of air outlet B well heater, forms the air-flow circulation.When the constant temperature enclosure temperature of gathering when temperature sensor 6 is higher than set temperature value, the refrigerator refrigeration, fan 3 is blown into the flat-temperature zone with cold airflow, thereby reaches temperature constant in the flat-temperature zone; When the constant temperature enclosure temperature of gathering when temperature sensor 6 is lower than set temperature value, through 5 actions of temperature controller 1 control solid-state relay, start well heater 4, fan 3 is blown into the flat-temperature zone with thermal current, thereby reaches temperature constant in the flat-temperature zone.
