[0029] The heat exchange module 2 includes multiple heat exchange cores 16. A partition plate 15 is provided in the shell 5 corresponding to the heat exchange core 16. The heat exchange core 16 is installed in the shell 5 through the partition plate 15. Space is left between adjacent heat exchange cores 16 to form a fresh air channel. The heat exchange core 16 is provided with a cavity. A heat exchange plate 18 is provided in the cavity. There are multiple heat exchange plates 18. Space is left between adjacent heat exchange plates 18 to form an exhaust gas channel.

[0030] The heat exchange plates 18 are arranged obliquely, and the cross-section of the cavity side walls of the adjacent heat exchange plates 18 and the heat exchange core 16 is a trapezoid, specifically, an isosceles trapezoid.

[0031] A plurality of spacer columns 17 are fixedly installed in the housing 5 , with spaces left between adjacent spacer columns 17 , and both ends of the heat exchange plate 18 are located in the spaces between adjacent spacer columns 17 .

[0032] The spacer columns 17 are fixedly mounted on the side walls at both ends of the partition plate 15 .

[0033] A space is left between the heat exchange module 2 and the side wall of the shell 5 , and the space is a fresh air bin 7 . One end of the fresh air channel is connected to the fresh air bin 7 , and the other end of the fresh air channel is connected to the outside of the shell 5 .

[0034] The exhaust gas bin includes an upper exhaust gas bin 9 and a lower exhaust gas bin 19. A space is left at the top of the heat exchange module 2 and the shell 5, which is the upper exhaust gas bin 9. The heat exchange module 2 leaves a space at the bottom of the shell 5, which is the lower exhaust gas bin 19. The exhaust gas outlet 4 is located at the bottom of the shell 5, and the lower exhaust gas bin 19 is connected to the outside of the shell 5 through the exhaust gas outlet 4.

[0035] A first side plate 10 is disposed on the top of one side of the heat exchange module 2 , and a second side plate 11 is disposed on the bottom. The first side plate 10 , the side of the heat exchange module 2 , the second side plate 11 and the inner wall of the shell 5 form a fresh air bin 7 .

[0036] The third side panel and the fourth side panel 13 are respectively installed between the top side wall and the bottom side wall of the heat exchange module 2 away from the fresh air bin 7 and the top side wall and the bottom side wall of the shell 5. The top of the heat exchange module 2, the third side panel 12, the first side panel 10 and the top side wall of the shell 5 form an upper exhaust gas bin 9, and the heat exchange module 2, the lower part of the heat exchange module 2, the fourth side panel 13, the second side panel 11 and the bottom side wall of the shell 5 form a lower exhaust gas bin 19.

[0037] A rain cover 14 is provided on the side of the housing 5, and the rain cover 14 is located on the top side wall of the housing 5 away from the fresh air bin 7. An electric box 8 is installed inside the housing 5.

[0038] This equipment mainly uses the waste heat of the exhaust gas in the house to heat the fresh cold air entering the house from the outside to reach the required temperature. Specifically, on the one hand, the exhaust gas with a certain temperature in the house enters the upper exhaust gas bin 9 through the exhaust gas fan 3, and under the action of pressure, the exhaust gas enters the heat exchange module 2 and then enters the house through the lower exhaust gas bin 19; on the other hand, the fresh air outside the house enters the fresh air bin 7 through the fresh air fan 1, at this time, the fresh air electric air valve 6 is in a closed state, and all the fresh air enters the heat exchange module 2, and heat is exchanged through the heat exchange core plate wall of the heat exchange module 2 to increase the temperature of the fresh air, and then enters the house. This process realizes the waste heat utilization of the exhaust gas in the house and improves the energy utilization efficiency.

[0039] When the external environment changes, it is necessary to lower the temperature of the fresh air entering the house. At this time, the fresh air electric air valve 6 is in the open state. A part of the fresh air entering the fresh air bin 7 through the fresh air fan 1 enters the heat exchange module 2 for heat exchange to increase the temperature of the fresh air. The other part directly enters the house after passing through the fresh air valve without heat exchange, thereby achieving the effect of lowering the temperature of the fresh air entering the house. The opening size of the fresh air electric air valve 6 can be controlled and adjusted by the control system. The specific opening area size is inversely proportional to the temperature requirement in the house. The higher the fresh air temperature required in the house, the smaller the opening area of ​​the fresh air electric air valve 6. The minimum is the closed state. The lower the fresh air temperature required in the house, the larger the opening area of ​​the fresh air electric air valve 6. By adjusting the opening size of the fresh air electric air valve 6, the temperature of the fresh air entering the house is adjusted to meet the different temperature requirements of the poultry house.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
