TH22232U - Temperature control cabinet - Google Patents

Abstract

The temperature-controlled cabinet consists of a battery chamber, air inlet and outlet ducts, a vapor compression chiller, a thermoelectric chiller, a fan, an in-duct thermometer, an inlet thermometer, and an outlet thermometer. It uses air as a medium for temperature control and regulates airflow through the battery. The airflow temperature is monitored using a thermometer to control the operation of two chilling systems, maintaining a constant battery temperature at a predetermined level. The battery chamber is designed to allow airflow into and across all surfaces of the battery, preventing dead zones. The air then flows out of the battery chamber. The cabinet utilizes two chilling and temperature control systems to precisely and accurately regulate the airflow temperature.

1. The temperature control cabinet consists of a battery room (1), air inlet (2), air outlet (3), vapor compression chiller (4), thermoelectric chiller (5), fan (6), in-duct thermometer (7), inlet thermometer (8), and outlet thermometer (9). It has the following characteristics: The battery room (1) is a hexagonal box with a hinged lid on top. The bottom of the hexagonal box is sealed, and the entire outer surface is covered with thermal insulation. The bottom of one side wall of the hexagonal box is connected to the air inlet (2), which is a long rectangular tube covered with thermal insulation. At the end of the air inlet (2), an axial flow fan (6) is installed to turn the ambient air into an airflow into the inside of the air inlet (2). The airflow passes through the vapor compression chiller (4), which is the evaporator part of the vapor compression air conditioner. The temperature is controlled using the temperature measured by the in-duct thermometer (7) installed on the outlet side of the vapor compression chiller (4), which will send... A signal is sent to the refrigerant supply controller to the evaporator inside the vapor compression chiller (4) to coarsely control the airflow temperature. The airflow then flows through the cold side fins of the thermoelectric chiller (5) located inside the inlet duct (2) and is controlled by the average temperature of the temperature readings from the inlet thermometer (8) and the outlet thermometer (9) installed on the air inlet and air outlet of the battery room (1), respectively. This sends a signal to the controller to control the power supply to the thermoelectric module to finely control the air temperature. Inside the battery room (1), the battery is placed so that one right angle of the battery is centered on the inlet duct (2) and the opposite right angle of the battery is centered on the outlet duct (3) so that airflow can flow across all surfaces of the battery without dead zones. The airflow then flows out of the battery room (1) through the outlet duct (3) installed on the battery room (1). The center of the wall surface opposite the wall where the air inlet pipe (2) is installed, in which this temperature control cabinet uses air as a medium to control the battery temperature so that it can be used to control the battery temperature for testing batteries that cannot be prevented from liquid seeping into the battery which causes a short circuit inside the battery, and there are two air cooling systems to enable the temperature to be controlled accurately to the specified value.
