Problems solved by technology

[0003] However, due to the limitation of the space structure in the cabin, cabin air conditioners are faced with the problems of miniaturization, high efficiency, energy saving, environmental protection, comfort and the improvement of related comprehensive technologies. internal demand, failing to achieve the purpose of improving the cabin environment
Moreover, the high-intensity bumps, vibrations, impacts or climbing that occur during the driving of the vehicle often cause the condensed water of the air conditioner to splash or overflow the water tank, causing water seepage in the cabin and affecting the environment in the cabin
On the other hand, this type of cabin air conditioner generally uses a vehicle-mounted DC power supply, and most of its fans are centrifugal, with a high pressure head (generally above 300Pa). Unfavorable factors such as excessive wind pressure, increased noise or water blowing

Embodiment 1

[0028] Such as figure 1 , figure 2 , image 3 As shown, the lower part of the heat exchanger 2 is arranged in the deep water tank 1, and the heat exchanger 2 is an integral body composed of the first evaporator 21 and the second evaporator 22 connected in parallel through respective side plates; the first evaporator 21 and the second evaporator The middle upper part of the second evaporator 22 is provided with an L-shaped baffle plate 3, the horizontal section of the baffle plate 3 is placed on the upper end surface of the second evaporator 22 to avoid a short circuit of the flow channel, and the vertical section of the baffle plate 3 is placed on the first The evaporator 21 is separated from the upper part of the second evaporator 22, and the vertical section of the baffle plate 3 is provided with ventilation holes to improve local heat exchange. The heights of the deep water tank 1 and the baffle plate 3 are both slightly greater than half of the height of the heat exchan...

Embodiment 2

[0030] Such as Figure 4 Shown is a schematic structural diagram of the first case of the heat exchange system of the present invention. The lower part of the heat exchanger 2 is arranged in the deep water tank 1, and the heat exchanger 2 is composed of the first evaporator 21 and the second evaporator 22 through respective side plates. A whole formed in parallel; the upper middle of the first evaporator 21 and the second evaporator 22 is provided with an L-shaped baffle 3, and the horizontal section of the baffle 3 is placed on the upper end surface of the second evaporator 22 to avoid flow passages short circuit. The fan 4 is placed behind the heat exchanger 2, that is, on one side of the second evaporator 22, thereby realizing the control of the height of the air conditioner and becoming an ultra-thin top-mounted air conditioner to adapt to the space in the low-profile cabin.

[0031] Of course, the blower fan 4 can also be placed in front of the heat exchanger 2, that is,...

Embodiment 3

[0033] Such as Figure 5 Shown is a schematic structural diagram of the second case of the heat exchange system of the present invention. The lower part of the heat exchanger 2 is arranged in the deep water tank 1, and the heat exchanger 2 is composed of the first evaporator 21 and the second evaporator 22 through respective side plates. A whole formed in parallel; the upper middle of the first evaporator 21 and the second evaporator 22 is provided with an L-shaped baffle 3, and the horizontal section of the baffle 3 is placed on the upper end surface of the second evaporator 22 to avoid flow passages short circuit. The blower fan 4 is placed above the heat exchanger 2, thereby realizing the control of the width of the air conditioner, and becoming an ultra-thin wall-mounted air conditioner to adapt to the narrow cabin space.

Abstract

The invention provides a heat exchanger system of a small type air conditioner for a cabin. The heat exchanger system comprises a heat exchanger and a fan, wherein the lower part of the heat exchanger is arranged in a deep water tank, and the heat exchanger comprises a first evaporator and a second evaporator which are connected in parallel through respective side boards; and a baffle plate is arranged at the upper middle part of each of the first evaporator and the second evaporator, and a baffle is arranged at the upper end of the second evaporator. According to the heat exchanger system of the small type air condition for the cabin, three baffle surfaces are formed by using the baffle plates and two surfaces of the deep-water tank to ensure that a heat exchanging channel is changed into a wave-shaped channel, heat exchanging is enhanced, the heat exchanging speed is increased; and the two same evaporators are connected in parallel to form an integral heat exchanger, and thus the structure of the air conditioner is compact, the size is reduced and the refrigerating capacity is increased, and the deep-water tank prevents the condensate water from spilling or overflowing and further polluting the environment in a cabin.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a heat exchange system for a small cabin air conditioner. Background technique [0002] Vehicles such as tanks, armored vehicles and shelters play an increasingly important role in military exercises and operations. With the development and updating of technology and the upgrading of vehicle systems, people pay more and more attention to the coordination and optimization of man-machine-environment technology. Therefore, tanks, armored vehicles and shelter vehicles are equipped with air conditioners to improve the cabin environment. Among them, steam Compression refrigeration air conditioner has been widely used in recent years as one of the air conditioners to improve the working environment in the cabin. [0003] However, due to the limitation of the space structure in the cabin, cabin air conditioners are faced with the problems of miniaturization, high efficiency, energy saving, environm...
