Detailed description of the invention
One of embodiment of Fig. 1 phase-change type heat exchange structure of the present invention
The another embodiment of Fig. 2 phase-change type heat exchange structure of the present invention
The structural schematic diagram of Fig. 3 battery group of the present invention
In figure, 1 heat exchange frame, 11 channels, plane made of 12 phase-change materials, 13 clads, 2 monocells,
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1, Figure 2, Fig. 3 is the specific embodiment of phase-change type heat exchange structure of the present invention, in the phase-change type heat exchange structure
In, a heat exchange frame 1 is all had, there are two plane, two planes to be used to be bonded with monocell face contact for heat exchange frame 1 tool,
To conduct heat to monocell.The channel 11 passed through for fluid media (medium) is opened up in frame 1, the channel is through entire heat exchange
The both ends of frame, the channel passed through for fluid media (medium) can be several, or one with battery cell contact surface phase
When a channel, for fluid medium channel through the both ends of heat exchange frame, at least one plane of the heat exchange frame is heat exchange material
Material or filling heat exchange material.
Above-mentioned phase-change type heat exchange structure, when being used to battery thermal management, when battery-heating power is smaller, fluid medium channel
Interior air or refrigerant can not flow, and the larger enthalpy for only relying on phase-change material absorbs the heat that battery generates, thus will
Battery temperature controls near transformation temperature.When battery-heating feed is larger, the air or refrigerant of fluid medium channel can be opened
Small flow is opened, is increased by the temperature of the heat absorption control battery of phase-change material, after the heat absorption of material to be phased reaches saturation enthalpy,
The flow circuit of air or refrigerant in fluid medium channel can take away the heat of battery generation, to reach energy-saving mesh
's.And when battery ambient environment temperature is lower, the heat that phase-change material is continued has the sky passed in battery and microchannel
Gas or refrigerant can extenuate the temperature-fall period of battery, play the purpose of certain auxiliary heating.
Specifically, phase-change type heat exchange structure, such as Fig. 1, the entirety for the frame that exchanges heat directly is made of phase-change material, in a timing
Air or refrigerant or coolant liquid in interior fluid medium channel do not flow the requirement that can satisfy battery heat dissipation yet.The heat exchange
When the connection type of frame and monocell, it is bonded in a plane of heat exchange frame or two plane patch double-sided adhesives with battery.It should
Kind heat exchange frame can be suppressed by inorganic phase-changing material, composite phase-change material etc..
It is second of embodiment of heat exchange frame, the main body for the frame that exchanges heat is by phase-change material and clad group such as Fig. 2
At clad is made from a material that be thermally conductive, and clad plays certain styling to phase-change material.The phase that this kind exchanges heat in frame
Becoming material can be organic phase change material.
In addition to aforesaid way, the frame that exchanges heat can also be directly made of rigid material, in heat exchange one of frame or
Phase-change material being coated or be bonded in two planes, phase-change material layers are made.
Specifically, heat exchange structure in battery pack with the connection type of monocell, can be according to monocell in battery pack
Arrangement is to determine, if heat exchange structure only carries out heat management to a monocell, then heat exchange structure can take monoplane to have phase transformation
The embodiment of material, as two planes of heat exchange structure are contacted with monocell, and it is equal to two monocells being in contact with it
It exchanges heat, then can take the embodiment such as Fig. 1 or Fig. 2, two planes all have phase-change material.
Further, the both ends of the microchannel of the heat exchange frame protrude from the edge for the monocell being in contact with it.
Wherein, exchange heat frame in phase-change material selection, can be selected according to the fusing point of different phase-change materials with meet
Heat exchange structure heat exchange demand.
Further, the thickness of the heat exchange frame, i.e. thickness between two planes, phase transformation in the frame that can exchange heat according to
Material and battery thermal discharge determine that the thickness for the frame that exchanges heat selects in 0.1mm~5mm.
Further, the phase-change material in the heat exchange frame, preferably insulating materials.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with scope of protection of the claims
Subject to.
