Hot-pressing conversion rigid flat pipe and battery thermal management device

Abstract

The invention relates to a hot-pressing conversion rigid flat pipe and a battery thermal management device. The hot-pressing conversion rigid flat pipe is used for thermal management of a heat generation component and is provided with a heating end and a cooling end, wherein an enclosed circulation loop is arranged in the hot-pressing conversion rigid flat pipe, the heating end and the cooling end communicate with each other by a connection passage, the enclosed circulation loop is filled with a heat conduction medium, a liquid heat conduction medium of the heating end generates a hot-pressing conversion heat transfer effect due to heating of the heat generation component and flows to the cooling end through the connection passage, heat generated during working of the heat generation component is rapidly transmitted to a condenser in contact with a wall surface of the cooling end and is dispersed, the liquid heat conduction medium flows to the heating end again, so that the hot-pressing heat transfer effect is continuously maintained by such circulation, and thermal management of the heat generation component is achieved. The hot-pressing conversion rigid flat pipe is faster in heat transfer and more rapid in response than an ordinary heat pipe.

Description

technical field [0001] The invention belongs to the technical field of battery heat management, and in particular relates to a heat-pressure conversion rigid flat tube and a battery heat management device. Background technique [0002] With the increase of battery power density, the problem of battery heating becomes more and more prominent. Among them, the optimal working temperature environment of lithium batteries is 20-35°C, but the temperature will continue to rise due to continuous charging and discharging during the working process, so a thermal management device is required to keep the battery within a temperature range suitable for efficient work . Air-cooled battery cooling systems and liquid-cooled battery cooling systems are common battery thermal management devices. The air-cooled battery heat dissipation system manages the temperature of the working battery by introducing cooling wind at the same temperature as the environment to blow across the surface of th...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the heat dissipation capacity of the existing air-cooled battery heat dissipation system is relatively low, while the liquid-cooled battery heat dissipation system requires a special pump drive, tight sealing and complicated pipeline design, and its cost is relatively high. For the defects of heat transfer lag of batteries with large heat generation, a heat-pressure conversion rigid flat tube and battery thermal management device are provided, which have stronger temperature control capabilities, faster heat transfer, and better use methods than existing air-cooled and liquid-cooled technologies.
