Problems solved by technology
However, when the central air conditioner adopts a medium-temperature water system, the structure of the conventional cross-flow surface cooler (see figure 1 ) has a relatively high outlet air temperature, which still cannot meet the cooling requirements. In view of this problem, a counter-flow surface cooler structure has also been proposed in the prior art (see figure 2 ), although the surface cooler of this structure reduces the outlet air temperature to a certain extent, but the degree of temperature reduction is limited, and it is still difficult to meet the cooling demand

The invention provides a heat exchanger and an air conditioner system. The heat exchanger comprises a plurality of columns of heat exchanging tubes separated from each other in the transverse direction, and the multiple heat exchanging tubes are arranged on each column; and the heat exchanger further comprises connecting tubes, wherein the connecting tubes are used for forming connection between the heat exchanging tubes so as to form heat exchanging medium flow paths in the heat exchanger, and each connecting tube comprises a first connecting tube which forms connection between the two heat exchanging tubes positioned in the same column and a second connecting tube which forms connection between the two heat exchanging tubes positioned in different columns. According to the heat exchanger, the complex and variable heat exchanging medium flow paths can be formed in the heat exchanger, so that the purpose of improving the heat exchanging efficiency is achieved, in addition, connection between all the heat exchanging tubes is flexible and varied, the design freedom is large, and different flow paths can be set according to different demands so as to obtain different heat exchanging efficiencies.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to a heat exchanger and an air conditioning system. Background technique [0002] The water-cooled central air-conditioning system usually includes a normal-temperature water system and a high-temperature water system. The inlet water temperature of the normal-temperature water system is usually 7°C, and the outlet water temperature is usually 12°C. Great advantages, but at the same time there is a disadvantage of high energy consumption of the host. The inlet water temperature of the high-temperature water system is usually 16°C, and the outlet water temperature is usually 21°C. This water system has the advantage of low energy consumption of the main engine. At the same time, due to the high outlet water temperature, the heat exchange efficiency of the terminal equipment is low, and the humidity is difficult to control. question. [0003] In order to solve the above problems, it ...
