Problems solved by technology
If the power of the fan is increased in order to increase the air volume flowing through this part of the evaporator 4, although the air volume flowing through here can be increased, the air volume flowing through the remaining parts of the evaporator 4 will also be increased accordingly, and For the rest of the evaporator 4, this is to increase the air volume on the basis of its relatively plump air volume, which is undoubtedly a waste

Embodiment Construction
[0028] refer to figure 2 , image 3 , Figure 4 and Figure 5 , as mentioned above, the lower part of the evaporator 4 in the cabinet air conditioner often only has a small air flow passing through, specifically, the lower part of the evaporator 4 occupies 1 / 9-1 / 10 of the overall length of the evaporator 4, in order to increase For the air volume flowing through here, in the technical solution of the present invention, an arc-shaped deflector bent plate 6 is arranged on the rear panel 5 opposite to the lower part of the evaporator 4, and the radius of the arc (mainly referring to the inner diameter here) should be 70mm- 80mm, the radian is between 80 degrees and 100 degrees, and its width should be equivalent to the width of the evaporator 4 (that is, approximately equal). When the air flow of the solid part of the plate 6 is guided by it to change the flow direction and flow to the lower part of the evaporator 4, it can cover the whole area of 1 / 9-1 / 10 of the lower part...

Abstract
The invention relates to a novel heat transferring system for a cabinet type air conditioner, which comprises an evaporator and a rear panel. An arc shaped wind-guide bending plate is arranged on the rear panel which is opposite to the lower portion of the evaporator, a plurality of diversion trenches are arranged on the wind-guiding bending plate, air current which flows through the entity portion of the wind-guide bending plate is introduced to the lower portion of the evaporator, and the air current which flows through the diversion trenches continuously flows along the original flowing direction. Thereby, a part of air current which is divided from the air current which is relatively affluent and originally flows to the upper portion of the evaporator flows to the lower portion of the evaporator, the air current of the lower portion of the evaporator is increased, and the air current which flows through the whole evaporator is more evenly, the heat transferring efficiency of the heat transferring system is enhanced, and the energy resource is saved.
Description
1. Technical field [0001] The invention relates to a cabinet type air conditioner, in particular to a heat exchange system of the cabinet type air conditioner. 2. Background technology [0002] Generally speaking, an air conditioner refers to a machine that sucks hot air in a room, exchanges heat with a low-temperature refrigerant, and then discharges it into the room (that is, a room that needs to be air-conditioned). Specifically, the work of the air conditioner is completed by a closed cycle system composed of a compressor, a condenser, an expansion device, and an evaporator. In this cycle system, the compressor is responsible for compressing the low-temperature and low-pressure gaseous refrigerant sucked into the compressor, and discharging it in a high-temperature and high-pressure state, and the discharged gaseous refrigerant releases latent heat to the outside when passing through the condenser, thereby transformed into a liquid state. At the same time, the pressure...
