Abstract

The invention provides a rapid heat exchange device based on heat conduction and medium phase change, and the device comprises at least one heat exchange assembly which comprises a hydrogen heat exchange part, an air heat exchange part and an integrated device shell; the hydrogen heat exchange part is arranged in the integration device shell in the first direction, the air heat exchange part is arranged in the integration device shell in the second direction, and the first direction intersects with the second direction. The hydrogen heat exchange part is located above the air heat exchange part, high-temperature gas subjected to heat exchange by the air heat exchange part ascends to exchange heat with low-temperature hydrogen of the hydrogen heat exchange part above, low-temperature gas subjected to heat exchange by the hydrogen heat exchange part descends based on gravity and then exchanges heat with the air heat exchange part below again, and the high-temperature air is cooled through reciprocating circulation; and the low-temperature hydrogen is heated to realize rapid heat exchange. The integration level of the whole machine is effectively improved; the cooling liquid capacity in the thermal management system is reduced, the response speed of system temperature control is increased, and the robustness of the thermal management system is improved.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a device for fast heat exchange based on heat conduction and medium phase transition. Background technique [0002] With the increasing problems of energy and environmental pollution, new energy vehicles, as a substitute for traditional fuel vehicles, are receiving more and more attention. Among them, electric vehicles powered by lithium-ion batteries have become the Research hotspots for manufacturers and scientific research institutions. Similar to traditional engines, lithium-ion power batteries will emit heat during operation. If there is no suitable thermal management solution, thermal runaway will easily occur, causing the power battery to catch fire, burn or even explode, thus affecting the personal safety of drivers and passengers. serious threat. In the electric vehicle models currently on sale, the heat dissipation of the power battery mainly relies on ...
