Description

Flat tube heat exchanger and air conditioner Technical Field The invention relates to the technical field of heat exchange equipment, in particular to a flat tube heat exchanger and an air conditioner. Background The flat tube heat exchanger has higher heat transfer efficiency due to the fact that the heat exchange of the flat tube increases the contact area of the heat transfer surface and the flow channels inside the flat tube and can promote the turbulent flow of fluid, and the like, and is widely applied to the field of heating ventilation and air conditioning. However, in the air conditioner, condensed water on the surface of the flat tube flows along the length direction of the flat tube due to surface tension, and flows to the outside of the water pan, resulting in water leakage of the air conditioner. In the prior art, in order to solve the problem of water leakage, the water receiving device is generally larger. However, the increase in the water pan causes an increase in the volume and cost of the air conditioner. Disclosure of Invention The invention solves the problem of water leakage caused by the fact that condensed water flows along the length direction of a flat tube under the condition of not increasing the volume of an air conditioner. In order to solve the above problems, the present invention provides a flat tube heat exchanger and an air conditioner capable of improving the problem that condensed water leaks out of a water receiving tray due to the condensed water flowing along the length direction of flat tubes. In a first aspect, the present invention provides a flat tube heat exchanger comprising a plurality of heat exchange fins and a flat tube; The heat exchange fins are sequentially arranged at intervals, and all the heat exchange fins are provided with mounting grooves; the flat tubes are internally provided with heat exchange flow channels and are arranged in the mounting grooves so as to exchange heat with all the heat exchange fins; the outside of flat tube is provided with water conservancy diversion portion, water conservancy diversion portion is used for water conservancy diversion comdenstion, in order to stop that the comdenstion flows along the length direction of flat tube. According to the application, the flow guide part is arranged on the outer side of the flat tube heat exchanger so as to prevent condensed water from flowing along the length direction of the flat tube, the flow guide part is used for promoting the condensed water to flow downwards, and the accumulation and retention time of the condensed water between the fins is shortened, so that a condensation waterway between the condensed water and the water receiving disc can be avoided, and the problem that the condensed water flows along the length direction of the outer side of the flat tube and leaks out of the outer side of the water receiving disc is solved. In an alternative embodiment, the flow guide is arranged on one or both sides of the width of the flat tube. Because the two sides of the width direction of the flat tube are easy to form a condensation water path between the two sides corresponding to the water receiving disc, the condensation water leaks out of the water receiving disc. The application sets the diversion part on one side or two sides of the width of the flat tube, so the diversion part can be used to downwards guide the water, thereby avoiding the condensation water path formed by the lap joint of the condensation water and the side wall of the water receiving disc, and the distance between the side wall of the water receiving disc and the end part of the flat tube can be reduced, thereby reducing the thickness of the air conditioner by sizing. In an alternative embodiment, the outer peripheral edge of the flat tube is provided with a plurality of flow guide portions at intervals along the longitudinal direction. The application is provided with a plurality of diversion parts, thereby better realizing diversion. In an alternative embodiment, the flow guide portion is a groove provided at the outer periphery of the flat tube. According to the application, the flow guide part is arranged as the groove, the gap between the flat tube and the side wall of the water receiving disc is increased at the position of the groove, and when condensate water flows to the groove along the length direction when one end of the condensate water along the length direction of the flat tube and the side wall of the water receiving disc are overlapped to form a condensate water path, the condensate water can fall into the water receiving disc from the groove due to the increase of the gap at the groove. In an alternative embodiment, the grooves are arranged in a direction perpendicular to the length direction of the flat tubes. The grooves are arranged in the direction perpendicular to the length direction of the flat tubes, so that condensed water can flow downwards after flowing to the concave parts. I
