Detailed Description
The following describes the runner total heat exchange system disclosed in the present invention with reference to the accompanying drawings.
Referring to fig. 1, the utility model discloses a runner total heat exchange system includes box 1, total heat exchange runner 2, runner support frame 3, sealing member 4 and division board 5, and wherein runner 2 passes through runner support frame 3 and sets up in the inside of box 1, and division board 5 sets up in box 1 along the length direction of runner support frame 3 to separate box 1 for return air room and fresh air room, sealing member 4 sets up on runner support frame 3 in order to reduce the cross wind between return air room and the fresh air room.
The box 1 is the outer shell structure of the runner total heat exchange system and is used for encapsulating other parts of the system inside. The box body 1 can be divided into a return air chamber and a fresh air chamber by a partition plate 5 arranged along the length direction of the rotating wheel support frame 3, wherein outside fresh air enters the fresh air chamber and passes through the rotating wheel 2 to enter the chamber to update indoor air, and the indoor air can pass through the rotating wheel 2 to enter the return air chamber and is discharged to the outside from the return air chamber.
The runner 2 is disposed inside the casing 1 and connected to an external driving device to be rotated by the external driving device. In one embodiment, the runner 2 comprises a body and a total heat exchange material filled in the body. The wheel body can be made of stainless steel or other alloy materials so as to ensure the service life of the wheel body. The total heat exchange material may be a material capable of realizing heat exchange, such as total heat exchange cotton or a honeycomb material, and is not particularly limited herein. Like this, when outdoor new trend and indoor return air passed runner 2, to take summer as an example, the heat of the higher new trend of outdoor temperature is absorbed and is cooled down by runner 2, and the heat in the total heat exchange material is absorbed and is arranged to outdoor to the lower return air of indoor temperature to realize the heat exchange of new trend and return air, reduce the energy that consumes for adjusting indoor temperature.
The runner support frame 3 is arranged in the box body 1 and used for supporting the runner 2. The wheel support frame 3 has two support plates arranged parallel to each other. Between the two support plates there is a support 6, the support 6 passing through the centre of the full heat exchange wheel 2, thereby supporting the wheel 2 within the tank 1. In order to reduce runner support frame 3 department return air and fresh air and mix, set up sealing member 4 respectively in one side of two backup pads of runner support frame 3 towards runner 2, promptly, set up two sealing members 4 in the inboard of runner support frame 3.
Can know by the above-mentioned explanation, the utility model discloses a runner total heat exchange system sets up sealing member 4 respectively through the one side of orientation runner 2 at two backup pads of runner support frame 3 and increases the new trend between runner support frame 3 and the runner 2 and the resistance that the return air is flowed each other to reduce the energy loss that causes because of the cross wind, and then improve this heat exchange system's effective rate of exchange.
Referring to fig. 2, in one embodiment of the invention, each of the two sealing members 4 comprises a base plate 41 and a plurality of ribs 42. The base plate 41 may be attached to a surface of a corresponding one of the two support plates, and the plurality of ribs 42 are disposed perpendicular to the surface of the base plate 41 and parallel to each other. In this way, the ribs 42 can act as barriers between the wheel 2 and the wheel support frame 3 to prevent the flow of fresh air and return air. In one embodiment, each seal 4 has 8 ribs 42. However, the number of the rib portions 42 can be adjusted by those skilled in the art according to the size of the runner 2 and the runner support frame 3, and it is within the scope of the present invention to provide different numbers of the rib portions 42.
In some embodiments, the distance between two adjacent ribs 42 of the plurality of ribs 42 is between 8mm and 12mm, the thickness of each of the plurality of ribs 42 is between 0.8mm and 1.2mm, and the height of each of the plurality of ribs 42 on the surface perpendicular to the base plate 41 is between 8mm and 12 mm. In some preferred embodiments, the distance between two adjacent ribs 42 of the plurality of ribs 42 is 10mm, the thickness of each of the plurality of ribs 42 is 1mm, and the height of each of the plurality of ribs 42 on the surface perpendicular to the base plate 41 is 10 mm. It will be understood by those skilled in the art that the size of the plurality of ribs 42 in the sealing member 4 can be adjusted according to the size of the different rotors 2 and rotor supports 3, and is within the scope of the present invention.
In one embodiment, each of the plurality of ribs 42 has a plurality of breaks perpendicular to the surface of the base plate 41, wherein the breaks of adjacent two ribs 42 of the plurality of ribs 42 are arranged in a staggered manner. Thus, when the airflow passes between the two support plates of the runner support frame 3, the airflow enters the sealing element 4 and increases airflow creep in the plurality of ribs 42, so that stable laminar flow is damaged, resistance is increased, and series flow is effectively avoided; the provision of the slits in the rib portions 42 reduces the resistance of the runner 2, and therefore, the reduction motor drive with a smaller power can be adopted. In one embodiment, each of the plurality of break seams has a width between 1.5mm and 2.5 mm. Preferably, each of the plurality of break seams has a width of 2 mm.
