Enhanced heat transfer element capable of automatically and transversely scanning fluid

Abstract

The invention discloses an enhanced heat transfer element capable of automatically and transversely scanning fluid, which comprises an enhanced heat transfer element shell, a first separator and a second separator, one end of the enhanced heat transfer element shell is provided with a fluid inlet, and the other end of the enhanced heat transfer element shell is provided with a first fluid outlet and a second fluid outlet; the first partition body and the second partition body are fixed in the enhanced heat transfer element shell and divide part of an inner cavity of the enhanced heat transfer element shell into a first side flow channel, a middle flow channel and a second side flow channel in the fluid flowing direction, and disturbance flow channels are further formed in the first partition body and the second partition body. Through the simple structural design, fluid automatically swings, so that a boundary layer on the heat exchange surface is eliminated, and the heat transfer enhancement effect is achieved.

Description

technical field [0001] The invention relates to a heat transfer element, in particular to an enhanced heat transfer element capable of automatically scanning fluid horizontally, and belongs to the technical field of heat exchange. Background technique [0002] In the process of shock heat exchange, when the fluid with the bottom temperature hits the surface of a high-temperature object, it will take away the heat on the surface of the object, thereby cooling the high-temperature components. However, for the traditional steady-state jet impingement heat transfer with a simple hole target structure, when the jet reaches the target surface, a stable flow boundary layer and a thermal boundary layer will be formed near the target surface due to the stable flow of the fluid. layer will reduce the effect of shock heat transfer. [0003] Therefore, it is necessary to design a new heat transfer element to break the flow boundary layer and thermal boundary layer of the stable jet and...
