Heat exchanger and air conditioner

Abstract

The invention discloses a heat exchanger and an air conditioner and relates to the field of heat exchange. The heat exchanger is used for realizing easy discharging of condensed water and ensuring the system reliability and the heat exchanging efficiency. The heat exchanger comprises a first pick-up tube, a second pick-up tube and heat exchanging pipes, wherein the upstream end of the heat exchanging pipe communicates with the first pick-up tube; the downstream end of the heat exchanging pipe communicates with the second pick-up tube; the space between two adjacent heat exchanging pipes at the upstream end is small than that between the two adjacent heat exchanging pipes at the downstream end. According to the technical scheme, as the space between two adjacent heat exchanging pipes at the upstream end is small than that between the two adjacent heat exchanging pipes at the downstream end, the space between the two adjacent heat exchanging pipes is larger when condensed water moves towards the downstream during the discharging process, and the condensed water is free of the water blocking phenomenon, so that air can conveniently circulates, the blowing rate is not lowered due to the condensed water, and the system reliability and the heat exchanging efficiency are ensured.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to a heat exchanger and an air conditioner. Background technique [0002] At present, the microchannel heat exchanger adopts fins with uniform fin spacing, and the heat exchange tubes are arranged horizontally and distributed layer by layer. This structure is easy to accumulate dust and water. If it is used for evaporative heat exchange, the condensed water is not easy to discharge, resulting in increased air circulation resistance, reduced air volume, and in severe cases, resulting in freezing, which greatly reduces system reliability and heat exchange efficiency. Contents of the invention [0003] One of the objectives of the present invention is to provide a heat exchanger and an air conditioner for easy discharge of condensed water, ensuring system reliability and heat exchange efficiency. [0004] To achieve the above object, the present invention provides the following technica...
