A shunt device, heat exchanger structure and air conditioner

Abstract

This invention provides a flow distribution device, a heat exchanger structure, and an air conditioner, wherein the air conditioner belongs to energy-saving refrigeration and air conditioning equipment. The flow distribution device includes a flow distribution plate structure, which has a first A-type interface group, a second A-type interface group, a first B-type interface group, and a second B-type interface group, respectively connected to the first A-type heat exchange tube on the leeward side, the second A-type heat exchange tube on the leeward side, and the first B-type heat exchange tube on the windward side and the second B-type heat exchange tube on the windward side; the first A-type heat exchange tube is connected to the first B-type heat exchange tube, and the second A-type heat exchange tube is connected to the second B-type heat exchange tube; the flow distribution plate structure also has a first refrigerant inlet, a second refrigerant inlet, and a flow path structure, the flow path structure connecting the first refrigerant inlet and the first A-type interface group, and connecting the first B-type interface group and the second A-type interface group, and connecting the second B-type interface group and the second refrigerant inlet. According to this invention, counter-current heat exchange can be fully utilized to increase the heat exchange temperature difference, thereby improving the heat exchange effect of the heat exchanger during refrigeration.
