Problems solved by technology
However, because they have more or less problems such as "low voltage, not suitable for excessive discharge, unfriendly environment, scarce raw materials, high price, high dependence on infrastructure, unsafe, and fewer cycles", although oxygen-metal batteries The above problems are overcome, but due to the incomplete conversion of chemical energy into electrical energy, the battery generates a lot of heat during work, which affects the work of the battery

The invention discloses an oxygen-metal battery rib plate heat dissipation structure based on electrolyte circulation. A main body of the rib plate heat dissipation structure is formed in a manner that an electrode is inserted into an enclosed or open battery case; a load is externally connected through a lead; a tank is filled with electrolyte, and is provided with a liquid outlet pipe and a liquid inlet pipe; and the liquid outlet pipe is connected with the liquid inlet pipe through an electrolyte circulator, thereby constructing a cycle. Rib plates are arranged inside the battery case, so that heat exchange with the electrolyte is facilitated. The rib plates are arranged outside the battery case, the liquid outlet pipe and the liquid inlet pipe, so that heat can be dissipated into the environment conveniently. Liquid convection is forced through the circulator, so that the uniform temperature field and concentration field of the electrolyte and full contact with the internal rib plates are ensured. The internal rib plates can be negative electrodes at the same time. Through adoption of the rib plate heat dissipation structure, the production of a large amount of heat during discharge of the oxygen-metal battery is avoided; the safety of the oxygen-metal battery is enhanced; and normal work of the oxygen-metal battery is ensured.
Description
technical field [0001] The invention relates to an oxygen-metal battery heat dissipation structure based on electrolyte circulation, and the main heat dissipation mode is rib plate heat dissipation. Oxygen-metal batteries are defined here more broadly, including air batteries. Background technique [0002] The emergence of batteries has greatly facilitated the power supply for outdoor operations. People have successively developed batteries such as lead storage batteries, nickel-metal hydride storage batteries, lithium-ion batteries, polymer lithium batteries, and fuel cells. However, because they have more or less problems such as "low voltage, not suitable for excessive discharge, unfriendly environment, scarce raw materials, high price, high dependence on infrastructure, unsafe, and fewer cycles", although oxygen-metal batteries The above problems are overcome, but due to incomplete conversion of chemical energy into electrical energy, the battery generates a large amoun...
