Liquid distribution pipeline assembly and heat exchange device

Abstract

The invention provides a liquid distribution pipeline assembly and a heat exchange device. A liquid distribution chamber, a flow collecting chamber, and a liquid distribution channel are formed insidethe liquid distribution pipeline assembly. The liquid distribution channel is used for communicating the liquid distribution chamber with the flow collecting chamber, and enables fluid in the liquiddistribution chamber to flow into a flat pipe chamber through the flow collecting chamber. At least one blocking element is arranged in the flow collecting chamber. The blocking elements divide the flow collecting chamber into a plurality of flow collecting chambers, and each of the flow collecting chambers corresponds to multiple flat pipes. According to the invention, the flow collecting chamberis divided into a plurality of flow collecting chambers which are spaced from one another through the blocking elements, so that the phenomenon of secondary mixed flow or turbulent flow of fluid in different areas in the flow collecting chamber is eliminated, and mutual interference between the fluid at different positions in the flow collecting chamber is prevented; therefore, the problem of non-uniform flow velocity when the fluid flows to the liquid using device from different positions in the flow collecting chamber is solved, each flow collecting chamber can uniformly collect the fluid from the liquid distributing chamber and uniformly supply the fluid to the liquid using device, and the uniformity of liquid distribution of the fluid by the liquid distributing pipeline assembly is improved.

Description

technical field [0001] The invention relates to the technical field of fluid control, in particular to a liquid distribution pipeline assembly and a heat exchange device. Background technique [0002] The liquid distribution pipeline assembly is a device that divides the concentrated inflow of fluid to form multiple fluid branches. It can transport the fluids of multiple branches to the liquid device respectively. There are liquid separation chambers for receiving fluids inside. The collecting chamber for connecting the liquid-using device, and the liquid-distributing channel for connecting the liquid-distributing chamber and the collecting chamber. The liquid separation effect of the existing liquid distribution pipeline components is not ideal.

Problems solved by technology

The liquid separation effect of the existing liquid distribution pipeline components is not ideal. After the fluid enters the manifold through the liquid separation channel from the liquid separation chamber, mixed flow will occur in the manifold, and the fluids located in different areas in the manifold Mixed with each other, so its flow trajectory is chaotic and disorderly, resulting in uneven flow velocity of the fluid in the manifold; in addition, because the fluid will be resisted by the inner wall of the liquid separation chamber, the flow velocity of the fluid in the liquid separation chamber will change, so it cannot be guaranteed The uniformity of the amount of liquid that the fluid enters into the manifold from different areas in the liquid separation chamber

The above factors lead to the inability of the fluid to enter the liquid device uniformly from all areas in the manifold, which reduces the uniformity of liquid distribution of the liquid distribution pipeline components, making it difficult to achieve uniform flow distribution, which in turn affects the operating effect of the liquid device
