DEVICE FOR STUDYING TEMPERATURE DEPENDENCIES OF DIFFERENT ENVIRONMENTS Russian patent published in 2023 - IPC G01N25/32 F25B21/02 

FIELD: devices for studying the temperature dependences.

SUBSTANCE: invention relates to portable heat or cold devices with program control and is intended to study temperature changes in the parameters of electronic components, liquid and gaseous media. A device for studying the temperature dependences of various environments includes a power source, a radiator, a Peltier element, a temperature sensor, a microcontroller, and a switching unit. The climate chamber has a removable lid with a transparent window. A thin layer of thermal paste is applied between the bottom of the Peltier element and the top of the heatsink. The fan and legs are attached to the bottom surface of the radiator. The temperature sensor and fan outputs are electrically connected in parallel to each other by the breadboard inputs. The outputs of the Peltier element are connected to the inputs of a voltage amplifier, the outputs of which are connected to the inputs of a port for supplying power to the voltage amplifier and a port for grounding the voltage amplifier of the microcontroller. The output of the port for transmitting a signal to a personal computer (PC) from the microcontroller is connected to the input of the PC port for receiving a signal from the PC microcontroller, in the control unit, which is made in the form of a parallelepiped, in the side surfaces of which there are holes for installing cables.

EFFECT: increased speed and accuracy of measuring.
