[0009] Due to the heat transfer efficiency of the evaporator, the lower half of the heat transfer is poor, that is, the heat transfer performance of the lower left branch is poor, and this design can only ensure that the number of U-shaped tubes with good heat transfer performance is 11, and the cooling capacity is low , so the cooling effect is low. At the same time, the heat exchange lengths of the first flow path and the second flow path are inconsistent, and the requirements for the production process of the air conditioner are increased.

Abstract
The invention provides flow paths of an evaporator. The heat exchange lengths and the heat exchange effects of the flow paths are basically the same, it is guaranteed that the heat exchange effects of branches are basically the same, manufacturability is good, and an air conditioner provided with the evaporator can reach high heat exchange efficiency under various working conditions. The flow paths comprise the evaporator, the first flow path and the second flow path. The evaporator comprises the left branch and the right branch, the left branch is composed of a lower left branch and an upper left branch, wherein the lower left branch is arranged into a row of tubes, the upper left branch is arranged into double rows of tubes, and the lower left branch, the upper left branch and the right branch which is arranged into the double rows of tubes are sequentially connected. The first flow path comprises a first liquid inlet tube, discharge tubes and straddle tubes of the lower left branch, discharge tubes of the upper left branch and a first liquid outlet tube, wherein the first liquid inlet tube, the discharge tubes and the straddle tubes of the lower left branch, the discharge tubes of the upper left branch and the first liquid outlet tube are sequentially connected. The straddle tubes are connected to the discharge tubes at the upper end of the lower left branch and the discharge tubes at the upper end of the upper left branch. The second flow path comprises a second liquid inlet pipe, discharge tubes of the right branch, discharge tubes of the upper left branch and a second liquid outlet tube, wherein the second liquid inlet pipe, the discharge tubes of the right branch, the discharge tubes of the upper left branch and the second liquid outlet tube are sequentially connected.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to an evaporator flow path. Background technique [0002] The air conditioner can adjust the temperature, humidity and cleanliness of the air in a closed space or area to meet the requirements of human comfort and indoor temperature. With the development of society and the diversification of the use of air conditioners, they are also gradually developing towards refinement. More and more companies are improving air conditioners in the direction of "small and thin". [0003] After the volume of the air conditioner becomes smaller, the air inlet must be narrowed, but the heat exchange in the upper part of the air outlet is good, but the heat exchange in the lower part is poor. Therefore, in order to cater to this heat exchange characteristic, air conditioner manufacturers are evaporating The lower half of the heat exchange difference of the evaporator is set from a double row of tubes...
