Problems solved by technology

For example, multiple air ducts are opened in the ventilation heat exchange plate, and the air enters from one end of the air duct, and the air is discharged from the other air duct. However, this structure will make the air duct connect to a long ventilation pipe, which greatly wastes the material of the ventilation pipe. And the cooling speed is slow, the cooling effect is poor
In addition, the existing ventilation and heat exchange plates have low strength and cannot be used in high-burning and pressure-bearing occasions, and their versatility is poor

Abstract

The invention discloses a high-efficiency and high-temperature ventilation and heat exchange device. The high-efficiency and high-temperature ventilation and heat exchange device comprises a ventilation and heat exchange plate. The ventilation and heat exchange plate is a hollow plate. A separating plate with a gap is arranged in the ventilation and heat exchange plate and divides the ventilationand heat exchange plate into a first independent plate body and a second independent plate body. A plurality of separating ribs are arranged in a cavity of the first plate body and a cavity of the second plate body and divide the cavities into a plurality of air channels. A plurality of ventilation holes are formed in each separating rib located at one end of the first plate body and one end of the second plate body so that the flow direction of air flow in the first plate body and the second plate body can be distributed in a U-shaped path mode. The high-efficiency and high-temperature ventilation and heat exchange device has the advantages that the cooling time can be greatly shortened, the cooling effect can be improved, the temperature is more uniform, and thermal expansion is little under the condition that the size of the ventilation and heat exchange plate is equal to that of an existing ventilation and heat exchange plate. The high-efficiency and high-temperature ventilation and heat exchange device has the advantages that the size of the ventilation and heat exchange plate can be a half that of the existing ventilation and heat exchange plate, and the raw material is greatly saved under the condition that the cooling effect of the ventilation and heat exchange plate is same to the cooling effect of the existing ventilation and heat exchange plate. When the high-efficiency and high-temperature ventilation and heat exchange device is used for cooling, the first plate body and the second plate body independently work. When high-efficiency high-temperature ventilationand heat exchange device is used for bearing combustion and pressure, the first plate body and the second plate body work together, and the strength of the overall structure is improved.

Description

technical field [0001] The invention relates to the technical field of ventilation and heat exchange, in particular to a high-efficiency high-temperature ventilation and heat exchange device. Background technique [0002] The current ventilated heat exchange plate is usually cooled externally, but external cooling will greatly reduce the cooling speed and the cooling effect is poor. The internal cooling structure of the ventilated heat exchange plate has also appeared in the prior art. For example, multiple air ducts are opened in the ventilation heat exchange plate, and the air enters from one end of the air duct, and the air is discharged from the other air duct. However, this structure will make the air duct connect to a long ventilation pipe, which greatly wastes the material of the ventilation pipe. And the cooling speed is slow, and the cooling effect is poor. In addition, the existing ventilated heat exchange plates have low strength and cannot be used in high-burni...
