High and low temperature cycle control equipment for new energy battery testing is used in the testing industry of new energy battery motors and other components.
The electric heater of the high and low temperature cycle control equipment for new energy battery testing is installed inside the body near the bottom of the oil tank, and the oil heater is provided on one side of the electric heater, the cooler on the side of the oil pump, and the side of the solenoid valve There is a filter screen, and the solenoid valve is provided with a coolant inlet at the rear side of the machine body. A heating fluid outlet is provided below the coolant inlet, and a coolant outlet is provided below the heating fluid outlet. One end of the temperature alarm A temperature-sensing head is provided, and a side of the temperature alarm is provided with an oil filling port near the upper end of the oil tank. A heating pipe, an electric heater, an oil pump, a cooler, a solenoid valve and a temperature alarm are provided inside the electric heater The devices are connected to the control panel through wires.
Cooling methods are divided into direct cooling and indirect cooling. Indirect cooling uses a cooling circuit separate from the main circuit, while in direct cooling, the cooling circuit directly participates in the main circuit. The high and low temperature circulation devices of water-carrying new energy batteries usually adopt the direct cooling method. The high- and low-temperature cycle control equipment for oil-carrying new energy battery testing uses indirect cooling because of the fact that water and oil cannot be mixed together during the heating process. The method usually uses a plate exchanger for cooling.
The internal main pipeline is circulated with high-temperature steam. At this time, the internal pipeline pressure is relatively large. If direct cooling is used, the external water pressure needs to be greater than the internal main pipeline water pressure to enter the main pipeline for cooling. This method is not feasible, so more indirect cooling is also used. Advantages and disadvantages of direct cooling: Direct cooling can only be used in lower temperature occasions, but direct cooling is used to cool down quickly. Advantages and disadvantages of indirect cooling: Indirect cooling is suitable for high-temperature oil or water heating, but the heat exchange rate is slow, and the heat will be lost in the heat exchange. Therefore, when the actual temperature of the medium deviates greatly from the set value, we use the direct cooling method with larger cooling capacity.
The application of high and low temperature cycle control equipment for new energy battery testing in the pharmaceutical and chemical industry has a lot of space, especially in the pharmaceutical and chemical industry, uneven or inappropriate temperature will cause unstable temperature control, so it has a good high and low temperature cycle Controlling equipment is important.
