[0002] In order to ensure the comfort of the living environment, a better ventilation environment is usually required to maintain the temperature regulation between indoor and outdoor. For example, the ventilation effect can be achieved by setting an opening fan on the window, and the opening fan is opened when necessary to achieve ventilation between indoor and outdoor.

[0003] When the indoor temperature is high, the indoor place is cooled down by ventilation or air conditioning. However, whether it is through opening windows for ventilation or using air conditioning for cooling, it will cause the mixing of indoor and outdoor air. It is not suitable for some places where indoor and outdoor air cannot be mixed. In addition, using air conditioning for cooling and cooling consumes a lot of electricity. Utility Model Content

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1As shown, the utility model provides an air-cooling heat exchange unit, including a silencer box 1, an indoor air inlet duct 2, an indoor return air duct 3, an outdoor air inlet duct 4, an outdoor exhaust duct 5 and a heat exchanger 6. An isolation plate 11 is arranged in the silencer box 1, and the isolation plate 11 divides the interior of the silencer box 1 into a return air area 12 and a heat exchange area 13. The heat exchanger 6 is arranged in the heat exchange area 13. The indoor air inlet duct 2 and the outdoor air inlet duct 4 are both connected with the heat exchanger 6, and are respectively used to input the indoor hot air into the heat exchanger 6 and to transport the outdoor cold air to the heat exchanger 6. The heat exchanger 6 is respectively connected with the return air area 12 and the heat exchange area 13, and is used to transport the indoor air after heat exchange to the return air area 12, and to transport the outdoor air after heat exchange to the heat exchange area 13. The outdoor exhaust duct 5 is connected with the heat exchange area 13, and is used to discharge the outdoor air after heat exchange to the outdoors. The indoor return air duct 3 is connected with the return air area 12, and is used to transport the indoor air after heat exchange back to the indoor.

[0021] It can be understood that by arranging different pipes in the heat exchanger 6, indoor hot air and outdoor cold air can be heat exchanged by using different pipes in the heat exchanger 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 the indoor air conditioning cooling, which can achieve the effect of energy saving and consumption reduction.

[0022] It can be understood that the heat exchanger 6 and the return air area 12 can be connected by a pipe passing through the partition 11, or by any other method as long as the indoor air after heat exchange in the heat exchanger 6 can be transmitted to the return air area 12.

[0023] 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.

[0024] Furthermore, a cooling pipeline and a heating pipeline are provided in the heat exchanger 6. The cooling pipeline is respectively connected to the indoor air inlet duct 2 and the return air area 12, and the heating pipeline is respectively connected to the outdoor air inlet duct 4 and the heat exchange area 13.

[0025] Furthermore, the cooling pipeline and the heating pipeline are arranged crosswise.

[0026] 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.

[0027] 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 .

[0028] 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.

[0029] 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 .

[0030] 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.

[0031] 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 .

[0032] Furthermore, the indoor return air duct 3 and the outdoor exhaust air duct 5 are both located on one side of the sound-absorbing box 1 and are parallel to each other.

[0033] Furthermore, the indoor air inlet duct 2 and the outdoor air inlet duct 4 intersect with each other.

[0034] 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.

[0035] 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, heat exchanger, return air area and indoor return air duct, and forms a flow path for outdoor air through the outdoor air inlet duct, heat exchanger, heat exchange area and outdoor exhaust duct, and uses an 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 for cooling and cooling, thereby achieving the purpose of energy saving and consumption reduction.

[0036] 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.
