摘要： A microchannel flat tube applicable in a microchannel heat exchanger includes a flat tube body and a row of channels. The row of channels is arranged in the flat tube body along a width direction. The row of channels extends through the flat tube body along a length direction. A cross-section of each channel includes a first width in the width direction and a first height in a thickness direction. The row of channels at least includes a first group of first channels, a second group of second channels and a third group of third channels along the width direction. The first widths of the first channels, the second channels and the third channels decrease at a fixed value, thereby facilitating the control of the thickness of the microchannel flat tube and improving the heat exchange efficiency.

摘要： A sensor includes a housing, a circuit board, and a sensor chip fixed on the circuit board. The housing defines a receiving cavity and a first channel extending through the housing. The first channel communicates with the receiving cavity and an outside of the sensor. The circuit board is at least partially received in the receiving cavity. At least a part of the circuit board is bonded and fixed to the housing by a thermal conductive glue. The sensor chip is adapted for sensing at least one of a humidity signal and a temperature signal of an environment in the receiving cavity. As a result, the monitoring accuracy is relatively improved.

摘要： A heat exchanger includes a first collecting pipe, a number of heat exchange tubes and a partition plate. The heat exchange tubes are inserted into the first collecting pipe. By means of the partition plate, a first inner cavity of the first collecting pipe is divided into a first sub-cavity and a second sub-cavity. One end of each heat exchange tube is in communication with the first sub-cavity. In the process of a refrigerant entering the first collecting pipe, the refrigerant flows into the second sub-cavity firstly, and forms a severe turbulence effect after interacting with the heat exchange tubes inserted into the second sub-cavity. Then, the refrigerant flows into the first sub-cavity through holes provided in the partition plate, and then flows into the heat exchange tubes. As a result, the uniformity of the two-phase refrigerant distribution can be relatively improved.

摘要： A thermal management system includes a cooling liquid circulation flow path, a refrigerant circulation flow path and a first heat exchanger. The first heat exchanger includes a first heat exchange portion and a second heat exchange portion. The cooling liquid circulation flow path includes a first heat exchange assembly, a second heat exchange assembly and a first branch. The thermal management system has a heating mode. After passing through the first heat exchange assembly, one path of the cooling liquid flows to the first branch, and another path of the cooling liquid flows to the second heat exchange assembly. The cooling liquid after flowing through the first branch and after flowing through the second heat exchange assembly merge and then flow to the first heat exchange portion. As a result, the number of heat exchangers used by the thermal management system to recover waste heat is reduced.
