Abstract

The invention discloses a heat transfer device, which is arranged outside a hydrogen storage tank and includes an inner sleeve spaced apart from the hydrogen storage tank. The outer wall of the innersleeve is provided with a plurality of fins. An outer sleeve is disposed outside the fins. The invention also discloses a heating system using the heat transfer device. The heating system includes a fuel cell, the hydrogen storage tank, a hydrogen supply pipe, an air inlet pipe, a fuel cell exhaust gas pipe or a cooling system, and the heat transfer device. The heat transfer device is disposed atthe hydrogen storage tank to transfer heat and increase turbulence intensity, thereby improving the heat transfer efficiency. The heating system, on the one hand, helps to reduce system energy consumption and improve comprehensive energy utilization efficiency, and on the other hand, achieves effective control of the hydrogen desorption working temperature of the hydrogen storage tank, and realizes the utilization of the maximum effective hydrogen storage capacity of a hydrogen storage system.

Description

technical field [0001] The invention relates to a hydrogen fuel cell system and the technical field of metal hydride hydrogen storage, in particular to a heat exchange device and a heating system. Background technique [0002] The working principle of the fuel cell is to generate electricity through the electrochemical reaction of hydrogen and oxygen. The electrical efficiency of the fuel cell is about 50%, that is, a fuel cell system that generates a certain power will simultaneously generate waste heat with the same power. [0003] At present, the waste heat generated by the fuel cell is mainly discharged in three ways: 1) The fuel cell itself emits heat to the atmosphere in the form of thermal radiation, and the size of the radiated heat is related to the surface structure of the fuel cell, the operating temperature and the ambient temperature; 2) Hydrogen and oxygen react to form a part of the water that absorbs heat and is vaporized, taking away the heat of the stack; ...
