Description
Technical Field
The invention relates to an integrated heat exchange structure of a battery module, and belongs to the technical field of battery heat management and heat transfer.
Background
High-temperature enhanced heat dissipation and low-temperature rapid heating are the key points of thermal management research of power batteries, wherein the enhanced heat transfer research of the batteries is the leading edge and the hot spot. At present, the research methods mainly comprise Phase Change Materials (PCM) based on a phase change process, heat conduction of a heat pipe and heat dissipation based on air cooling and liquid cooling. The phase change material PCM or heat pipe structure can obviously strengthen the heat conduction of the battery and realize temperature equalization. The latent heat of the PCM absorbs the heat generated by the battery, and the heat conducting performance of the PCM is improved by preparing the PCM or adding materials such as foam metal and graphite, but the PCM has the defects of leakage, insufficient latent heat and the like. The heat pipe has strong heat conduction capability and good temperature balance, common heat pipes comprise a gravity heat pipe, a sintering heat pipe, a pulsating heat pipe and the like, and the novel structure comprises a micro-channel heat pipe, a flat heat pipe, a loop heat pipe and the like. Air cooling and liquid cooling heat dissipation which take air or liquid as a cooling medium are two main ways for realizing heat dissipation of the commercial battery module at present. Air cooling is divided into a natural convection mode and a forced cooling mode, but the heat dissipation and temperature equalization effects are poor, particularly under the conditions of high-rate and high-power charging and discharging of a battery module. The liquid cooling is divided into direct cooling and indirect cooling, the direct cooling immerses the battery module in insulating liquid to realize heat transfer, and the indirect cooling realizes heat convection with the battery module through circulation of cooling liquid in the liquid cooling plate runner. Because the liquid convection heat transfer coefficient is higher than the gas convection heat transfer coefficient, the actual liquid cooling effect is better than air cooling, which has become the mainstream trend at present, but the temperature uniformity of the battery module is poorer in the liquid cooling heat dissipation mode. With the increase of the energy density of the battery and the requirement of high-rate charge and discharge of the battery, efficient heat dissipation is difficult to realize only by adopting a single heat dissipation mode, and particularly, severe heat generation under extreme conditions is dealt with. Research shows that more effective battery heat dissipation can be realized through the combination of heat pipe heat conduction and liquid cooling plate centralized heat dissipation, and the design of the heat exchange structure with centralized heat conduction and gradient heat dissipation can effectively reduce the working temperature of the battery and improve the temperature uniformity of the battery module.
At present, the structural design of heat pipe and liquid cooling technology combined heat dissipation is still in a research stage, the structural basis of numerous experiments and simulation is that a plurality of cylindrical heat pipes with fins generate heat to be led into a liquid cooling channel, the cylindrical heat pipes and the liquid cooling channel are independent parts and are combined through a one-way liquid cooling channel, the heat exchange between a heat pipe condensation section and cooling liquid is insufficient, the heat exchange of the condensation section is enhanced, the cooling flow needs to be increased, so that the volume of the liquid cooling channel is larger, the heat dissipation capacity of downstream liquid to the downstream heat pipe due to higher temperature is obviously lower than that of an upstream heat pipe, and the temperature.

The design that heat pipe condensation segment and cold plate integration formed fluid passage combines together heat pipe high efficiency heat conductivity ability and cold plate cooling capacity, realizes concentrating heat conduction and gradient heat transfer, not only can realize high-efficient heat dissipation, reduces battery operating temperature, can also promote the temperature uniformity of battery module.

Detailed Description
The structure and the specific implementation mode of the invention are further explained by combining the drawings as follows:
fig. 1 is a schematic diagram of an integrated heat exchange structure based on a battery module according to the present invention, the integrated heat exchange structure includes a cold plate 6 and at least one separated flat heat pipe, the cold plate is disposed below the battery module 1; each separated flat heat pipe is composed of a heat pipe evaporation section 2, a heat pipe bending section 4 and a heat pipe condensation section 5, the thickness of each separated flat heat pipe is as thin as millimeters, the materials are aluminum or copper, a liquid absorption core and a phase change medium are contained in each separated flat heat pipe, the working capacity of each separated flat heat pipe is not influenced by gravity or inclination of the heat pipe, and the separated flat heat pipe has the effects of heat exchange strengthening and flat plate temperature averaging under the microscale. The separated flat heat pipe can also be additionally provided with a heat insulation section between the evaporation section and the bending section so as to meet the long-distance heat conduction requirement of the battery module heat management system. The heat pipe evaporation section 2 is tightly attached to two sides of the battery module 1, and the heat pipe condensation section 5 is arranged inside the cold plate 6. One end of the heat pipe bending section 4 is connected with the heat pipe evaporation section 2 through a heat pipe connecting piece 3 so as to be convenient to disassemble and maintain, and the other end of the heat pipe bending section is fixedly connected with the heat pipe condensation section 5; the heat pipe bending section 4 is beneficial to flexible arrangement of the heat pipe and cold plate integrated structure, and the heat pipe condensation section is arranged inside the cold plate to form an integrated fluid channel 7, so that the size of the heat exchange system is reduced.
As shown in fig. 2, the cold plate is disposed below the battery module, the fluid channel therein is a micro channel, the thickness is millimeter, and fluid flow circulation is realized through the fluid inlet and outlet. When the battery module generates heat in the charging and discharging process, the phase change medium in the separated flat heat pipe is heated and evaporated in the evaporation section, flows through the bending section along the pipeline in the heat pipe and then reaches the condensation section, and transfers the heat to the cooling fluid in the cold plate when meeting the condensation junction to realize heat exchange, and the liquid after the exchange condensation is driven by the capillary force of the liquid absorption core to flow back to the evaporation section; the heat is finally carried away from the battery module by the cooling fluid, and the high-efficiency heat dissipation and temperature equalization effects are achieved.
The condensation section 5 of the heat pipe belongs to the internal structure of the cold plate (shown by a dotted line in fig. 2) and forms the main structure of the cold plate together with the fluid channel; the thin plane of the condensing section perpendicular to the thickness direction is a parallelogram, so that the characteristic that the included angle between the flow channel between the condensing sections of the adjacent heat pipes and the central line of the cold plate is inclined is formed, and the flow resistance of fluid in the flow channel of the cold plate is reduced; the cooling fluid circulates in the cold plate through the fluid inlet 7a, the fluid outlet 7 b.
Fig. 3a is a sectional view taken along line a-a of fig. 2, which shows the connection relationship between the evaporation section 2, the condensation section 5 and the bending section 4 of the heat pipe, and the structure relationship of the integrated fluid channel formed by the cold plate 6 and the condensation section 5 of the heat pipe.
Fig. 3B is a sectional view taken along line B-B of fig. 2, illustrating the internal configuration of the cold plate, and illustrating fluid flow within the fluid passageways of the cold plate. As can be seen from the figure, the fluid channel 7 in the cold plate is a dual-flow-direction vein-type flow channel, and the vein-type flow channel is formed by symmetrically arranging a plurality of heat pipe condensation sections on the center line of the length direction of the plane of the cold plate; the heat pipe condensation sections on the same side of the central line are uniformly arranged at intervals; fluid passages are formed between the adjacent heat pipe condensation sections and between the heat pipe condensation sections and the side wall surface of the cold plate. The thin plane of the heat pipe condensation section in the direction perpendicular to the thickness direction preferably adopts a parallelogram structure, so that the characteristic that the included angle between the flow channel between the adjacent heat pipe condensation sections and the central line of the cold plate is inclined is formed, and the flowing resistance of the fluid in the flow channel of the cold plate is reduced. The cooling fluid of the cold plate may be a single phase gas, a single phase coolant, or a two phase fluid. The fluid flows in from the fluid inlets 7a on both sides of the symmetry line in two directions respectively, is branched and converged in the flow channel, and performs flow heat exchange with the wall surface of the condensation section of the heat pipe under the microscale to dissipate the heat of the condensation section of the heat pipe, and the fluid carrying the heat flows out from the fluid outlet 7b after the temperature of the fluid rises; the fluid flow directions of the two sides of the central line of the cold plate are symmetrically opposite, so that the condition that the temperatures of the condensation sections of the heat pipes at different positions in the cold plate are inconsistent is avoided, and the integral temperature equalizing effect of the cold plate is realized.
Fig. 4 is a schematic structural diagram of a fluid channel with micro spoilers and micro grooves, the fluid channel 7 in the cold plate is a micro channel, and the micro spoilers 8 and the micro grooves 9 can be arranged at intervals in the fluid channel, or both the micro spoilers and the micro grooves can be arranged at intervals in the fluid channel, so as to destroy a wall surface thermal boundary layer when the fluid and the condensation section of the heat pipe perform convective heat transfer, and disturb the flow, thereby realizing the effect of heat transfer enhancement.
