For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1-Figure 8 As shown, an embodiment of the present invention provides an energy-saving air heat exchange device, including an air intake component, a shell 1 and a heat exchange component. The shell 1 is made of high-temperature resistant nylon material. The nylon material is light and can effectively reduce the overall weight. The air intake component includes a first fan 2 and a drive motor 201. The output shaft of the drive motor 201 is fixedly connected to the first fan 2. A plurality of skeleton bars 202 are fixedly connected to the outer peripheral wall of the drive motor 201. The plurality of skeleton bars 202 can prevent debris from passing through. One end of the plurality of skeleton bars 202 is commonly connected to a mounting ring 203. The mounting ring 203 is connected to one end of the shell 1. The mounting ring 203 The housing 1 is snap-connected to facilitate the disassembly and assembly of the first fan 2. The air inlet assembly also includes a second fan, which is installed at the other end of the housing 1. The air outlet direction of the second fan is opposite to that of the first fan 2. The second fan includes a connecting shaft 205 and a fan blade group 206. The fan blade group 206 is arranged on the outer peripheral wall of the connecting shaft 205. A horn cover 207 is fixedly connected to the outer peripheral wall of the connecting shaft 205. A first air outlet 208 is arranged between the horn cover 207 and the housing 1. A second air outlet 204 is arranged in the middle of the horn cover 207. The heat exchange assembly is arranged in the housing 1, and the heat exchange assembly is between the first fan 2 and the second fan. A gas reflux component is provided on the shell 1, a first air cavity 3 is opened between the first fan 2 and the heat exchange component, and a second air cavity 301 is opened between the heat exchange component and the second fan. When the first fan 2 rotates synchronously with the second fan, part of the gas in the second air cavity 301 can enter the first air cavity 3 along the gas reflux component.

[0030] Specific: Figure 5 In the normal mode, the first fan 2 is started to introduce fresh air, which passes through the first air cavity 3, the heat exchange component, and the second air cavity 301 in sequence, and is finally blown out from the first air outlet 208 and the second air outlet 204. During this process, the second fan is not started.

[0031] Figure 4 In the energy-saving mode, when there is no requirement for the time of changing the ambient temperature, that is, when the ambient temperature does not need to reach the specified temperature rapidly, the first fan 2 and the second fan rotate synchronously, and the gas enters along the first air cavity 3, and then enters the second air cavity 301 through the heat exchange component. Part of the gas entering the second air cavity 301 enters the environment along the second air outlet 204, and the remaining part of the gas enters the gas reflux component under the action of the second fan. The gas entering the gas reflux component will be subjected to heat exchange treatment through the heat exchange component again.

[0032] It is understandable that when the second fan is turned on, it has the following two energy-saving effects: First, the second fan causes part of the heat-exchanged air to re-enter the first air cavity 3, and then re-enter the heat exchange component for heat exchange processing, that is, the gas re-entering the first air cavity 3 can occupy the volume of the first air cavity 3, effectively reducing the external air sucked in by the first fan 2, because the temperature of the heat-exchanged gas is closer to the required temperature in the environment than the newly inhaled external gas, so the energy consumption required for heat exchange can be effectively reduced; Second: The second fan will inhale part of the heat-exchanged gas in the environment, and in winter, the gas temperature in the environment is higher than the outside gas temperature, that is, the temperature of the heat-exchanged gas and the gas in the environment are both higher than the outside gas temperature, which again effectively reduces the energy consumption required for heat exchange.

[0037] The gas reflux assembly includes a plurality of air inlet shells 6, which are arranged on the outer peripheral wall of the shell 1. The shell 1 is provided with a plurality of groups of air vents, each group of air vents includes an inlet and an outlet, and the plurality of groups of air vents correspond one-to-one to the plurality of air inlet shells 6.

[0038] Specifically: in the normal mode, the two sealing blocks 602 seal the inlet and the outlet respectively.
