Abstract

The invention provides a manifold shell-and-tube heat exchanger which comprises a shell, a hot fluid manifold layer, a cold fluid manifold layer and a heat exchange capillary force layer are arranged in the shell, the heat exchange capillary force layer comprises a hot fluid capillary force layer and a cold fluid capillary force layer, and 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, the hot fluid capillary force layer and the cold fluid capillary force layer do not communicate with each other, and hot fluid and cold fluid exchange heat through the heat exchange capillary force layer. The invention provides a manifold type micro-channel heat exchanger capable of realizing heat exchange of cold and hot fluids. The overall pressure loss can be reduced, the advantages of manifold impact jet flow can be achieved, and fluid disturbance and heat exchange are enhanced. Meanwhile, uniform distribution of fluid and reverse flow of cold and hot fluid can be guaranteed, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to a heat exchanger technology, in particular to a heat pipe heat exchanger, which belongs to the heat pipe field of F28d15 / 02. Background technique [0002] A heat exchanger is a device that exchanges heat between hot and cold fluids, also known as a heat exchanger. Heat exchangers are widely used in many fields. In fields such as electronics, petrochemicals, communications, aerospace and other fields, due to their special working scenarios, there are special requirements for the size and weight of the heat exchanger, and it is required to have a stronger heat exchange capacity. 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 increase its heat transfer capacity by using the higher specific surface area of ​​the microchannels. However, although its heat exchange capacity is strong, the overall pressure loss of the microcha...
