[0017] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0018] like Figure 1As shown, the utility model provides an air-cooling heat exchange unit, including a muffler box 1, two indoor air inlet ducts 2, an indoor return air duct 3, two outdoor air inlet ducts 4, an outdoor exhaust duct 5 and two heat exchangers 6. Two first isolation plates 11 and two second isolation plates 12 are arranged in the muffler box 1. The two first isolation plates 11 divide the interior of the muffler box 1 into two air inlet areas 13 and a heat exchange area 14. The two air inlet areas 13 are respectively located on both sides of the heat exchange area 14. The two second isolation plates 12 are respectively arranged in the two air inlet areas 13 to separate the two air inlet areas 13. The two heat exchangers 6 are respectively arranged on the two first isolation plates 11, and the heat exchangers 6 are respectively arranged on the two first isolation plates 11. The two indoor air inlet ducts 2 are respectively connected to the parts of the two heat exchangers 6 extending into the two air inlet areas 13, and are used to input the indoor hot air into the two heat exchangers 6. The two outdoor air inlet ducts 4 are respectively connected to the parts of the two heat exchangers 6 extending into the two air inlet areas 13, and are used to transport the outdoor cold air to the heat exchanger 6. The indoor return air duct 3 is connected to the parts of the two heat exchangers 6 extending into the heat exchange area 14, and is used to transport the indoor air after heat exchange back to the room. The outdoor exhaust duct 5 is connected to the parts of the two heat exchangers 6 extending into the heat exchange area 14, and is used to discharge the outdoor air after heat exchange to the outside.

[0019] It can be understood that by arranging different pipes in the two heat exchangers 6, indoor hot air and outdoor cold air can be heat exchanged by using different pipes in the two heat exchangers 6, and mixing of indoor and outdoor air can be avoided. At the same time, the natural temperature difference of the outside world is used to replace indoor air conditioning cooling, which can achieve the effect of energy saving and consumption reduction.

[0020] It can be understood that the two indoor air inlet ducts 2, the indoor return air duct 3, the two outdoor air inlet ducts 4, and the outdoor exhaust duct 5 can all be connected to the two heat exchangers 6 through sealed pipelines, thereby avoiding mixing of indoor and outdoor air.

[0021] It can be understood that the pipelines in the heat exchanger 6 can be arranged in any form, as long as it is ensured that the indoor hot air and the outdoor cold air can exchange heat in the heat exchanger 6 and the two air will not mix.

[0022] It can be understood that a cooling pipeline and a heating pipeline are arranged in the heat exchanger 6. The cooling pipeline is connected to the indoor air inlet duct 2 and the indoor return air duct 3 respectively, and the heating pipeline is connected to the outdoor air inlet duct 4 and the outdoor exhaust duct 5 respectively.

[0023] Furthermore, the cooling pipeline and the heating pipeline are arranged crosswise.

[0024] It can be understood that the indoor hot air entering from the indoor air inlet duct 2 enters the cooling pipeline, and the outdoor cold air entering from the outdoor air inlet duct 4 enters the heating pipeline. The two types of air circulate in the heating pipeline and the cooling pipeline respectively to achieve heat exchange.

[0025] Furthermore, an indoor air intake fan is provided at the indoor air intake duct 2 for drawing indoor hot air into the indoor air intake duct 2 .

[0026] Furthermore, an indoor return air fan 31 is provided at the indoor return air duct 3 for conveying the cooled indoor air back into the room.

[0027] Furthermore, an outdoor air intake fan is provided at the outdoor air intake duct 4 for drawing outdoor cold air into the outdoor air intake duct 4 .

[0028] Furthermore, an outdoor exhaust fan 51 is provided at the outdoor exhaust duct 5 to discharge the outdoor air after the heat exchange is completed to the outdoors.

[0029] Furthermore, a filter 41 is provided on the outdoor air inlet duct 4 for filtering the outdoor cold air entering the outdoor air inlet duct 4 .

[0030] Furthermore, the indoor return air duct 3 and the outdoor exhaust air duct 5 are respectively located on two opposite sides of the sound-absorbing box 1 .

[0031] Furthermore, the two indoor air inlet ducts 2 and the two outdoor air inlet ducts 4 are respectively located on opposite sides of the sound-absorbing box 1 .

[0032] The working principle of the utility model is as follows: the indoor hot air and the outdoor cold air are drawn into the indoor air inlet duct 2 and the outdoor air inlet duct 4 respectively through the indoor air inlet duct 2 and the outdoor air inlet duct 4, and enter the cooling duct and the heating duct of the heat exchanger 6 respectively through the indoor air inlet duct 2 and the outdoor air inlet duct 4, and heat exchange is performed in the heat exchanger 6. After the heat exchange is completed, the temperature of the indoor hot air is reduced and is transported back to the room from the indoor return air duct 3, while the temperature of the outdoor cold air is increased and is discharged to the outside from the outdoor exhaust duct 5. In the whole heat exchange process, the indoor air and the outdoor air do not come into contact and mix.

[0033] It can be seen from the above embodiments that the utility model forms a flow path for indoor air through the indoor air inlet duct, the heat exchanger and the indoor return air duct, and forms a flow path for outdoor air through the outdoor air inlet duct, the heat exchanger and the outdoor exhaust duct, and uses a first isolation plate for isolation, so that while the indoor air and the outdoor air exchange heat in the heat exchanger, the two air types do not come into contact and mix, and only needs to drive a low-power fan, and the practical electric energy is much less than that of indoor air conditioning cooling, thereby achieving the purpose of energy saving and consumption reduction.

[0034] The device described in the utility model is not limited to the embodiments described in the specific implementation manner. Those skilled in the art may derive other implementation manners based on the technical solution of the utility model, which also fall within the technical innovation scope of the utility model.
