Abstract

The present invention provides a manifold shell-and-tube heat exchanger, comprising an outer shell, wherein a hot fluid manifold layer, a cold fluid manifold layer and a heat exchange capillary force layer are arranged in the outer shell, wherein the heat exchange capillary force layer includes a hot fluid The capillary force layer and the cold fluid capillary force layer, the cold fluid manifold layer is attached to the cold fluid capillary force layer, the hot fluid manifold layer is attached to the hot fluid capillary force layer, and the hot fluid capillary force layer and the cold fluid capillary force layer are mutually Without communication, the hot fluid and the cold fluid exchange heat through the heat exchange capillary layer. The invention provides a manifold type micro-channel heat exchanger which can realize the heat exchange of cold and hot fluids. It can not only reduce the overall pressure loss, but also combine the advantages of the manifold impingement jet to enhance fluid disturbance and heat exchange. At the same time, it can ensure the uniform distribution of the fluid and the counterflow of the hot and cold fluids, and improve the heat exchange efficiency.

Description

technical field [0001] The invention relates to a heat exchanger technology, in particular to a heat pipe heat exchanger, which belongs to the field of heat pipes of F28d15 / 02. Background technique [0002] A heat exchanger is a device that exchanges heat between cold and hot fluids, also known as a heat exchanger. Heat exchangers are widely used in many fields. In fields such as electronics, petrochemicals, communications, aerospace, etc., due to their special working scenarios, there are special requirements for the size and weight of heat exchangers, and their heat transfer capabilities are required to be stronger. In 1981, some scholars proposed the use of microchannels for heat dissipation, which can not only reduce the volume of the heat exchanger but also greatly improve its heat exchange capacity by using the higher specific surface area of ​​the microchannel. However, although the heat exchange capacity is strong, the overall pressure loss is also high due to the ...
