The invention relates to a special-shaped capillary runner heat exchanger. The heat exchanger comprises a core body 1, an upper header connecting pipe flange arranged at the upper end of the core body and connected with a hot fluid inlet, a lower header connecting pipe flange arranged at the lower end of the core body and connected with a hot fluid outlet, and header connecting pipe flanges arranged on the left and right two sides of the core body and connected with cooling medium inlet and outlet pipelines by at least one; and the intake port area of the upper header connecting pipe flange is larger than the exhaust port area of the lower header connecting pipe flange. The special-shaped capillary runner heat exchanger is suitable for the working conditions of smaller size and weight of the heat exchanger according to the scene conditions: such as multiple working condition technical requirements of such system devices as ships, ocean platforms and fuel cell vehicle hydrogen refueling stations.
Description
Technical field [0001] The invention belongs to the field of heat exchange equipment, and in particular relates to a special-shaped capillary channel heat exchanger, which is used for gas liquefaction, heating, and cooling; liquid gasification, heating, cooling, and fractionation; chemical reactions and other process systems . Background technique [0002] At present, the above-mentioned fields, especially in the equipment system of large-scale high temperature, high pressure and large temperature difference heat exchange conditions, use shell and tube heat exchangers. After long-term development, the shell and tube heat exchanger technology has become mature, but due to its process and structure limitations Factors such as those may lead to problems, specifically: [0003] ①. In some major projects, the inner diameter (equivalent diameter) of the heat transfer tube of the shell-and-tube heat exchanger is larger, such as φ19mm, the tube wall is thicker, the thermal resistance incr...
