Description
Technical Field
The utility model belongs to the technical field of power battery, specifically belong to a modular battery module submergence formula liquid cooling system of intercommunication each other.
Background
The development of electric automobiles is an important strategy for energy conservation and environmental protection. The lithium ion battery-based electric automobile has the advantages of zero emission, long endurance and the like, so that the new energy electric automobile taking the lithium battery as a power source is increased by 35% every year in China. However, lithium batteries are highly sensitive to temperature, and the optimal working temperature range is as follows: 15-35 ℃ and the temperature difference should be controlled within 5 ℃. When the temperature of the lithium battery is too high or too low, the life of the lithium battery is greatly affected. Therefore, the development of an efficient battery thermal management system is of great significance in practical application.
At present, the heat management modes of the power battery are mainly 4, namely air cooling type, liquid cooling type, phase change material cooling and refrigerant direct cooling. In the patent of "a power battery air cooling module" (patent No. CN201922045742.7), lenyi et al use air cooling to dissipate heat from a cylindrical battery module, which has the advantages of simple structure and low cost, but it is greatly affected by the ambient temperature and is difficult to dissipate heat from the battery module in hot seasons.
In the patent of 'liquid cooling system for battery pack of electric vehicle' (patent number: CN201921695885.6), by zhao yongan et al, the battery module is cooled by liquid, which has the advantage that the heat conductivity coefficient of the liquid is much higher than that of air, so as to achieve better heat dissipation effect. However, once the liquid cooling system leaks, the battery is in danger of short circuit, and certain potential safety hazards exist.
In the patent of 'a high-power lithium ion battery thermal management system' (patent number: CN201820855714.4), Dynasty utilizes a phase-change material cooling mode to dissipate heat of a battery, and has the advantages of simple structure and low energy consumption. However, the phase-change material has a low thermal conductivity and cannot absorb heat in time under the condition of high-rate discharge.
In the patent of 'a power battery system adopting a refrigerant direct cooling system' (patent number: CN201621061832.5), Sunshiqiang et al use refrigerant direct cooling to dissipate heat of a battery pack and have the advantages of omitting an intermediate heat exchange link and greatly improving heat exchange efficiency. However, the temperature equalization design of the evaporator is very difficult, and there is no effective way to achieve uniform temperature of each evaporating plate.
In view of the above-mentioned shortcomings of the conventional battery heat management, some research institutes have proposed the concept of immersion liquid cooling. For example, the patent of "sealed immersed battery pack based on fluorinated liquid and cooling system thereof" (patent No. 201822187949.3) by people of Tanksmart et al proposes that the whole battery module is arranged in a sealed box body, and the structure is simple and the energy density is high. But the power battery who uses on the existing market all is the modularization, and it is unrealistic to seal all batteries in unison in a box, consequently the utility model provides a modular battery module submergence formula liquid cooling system that communicates each other.

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. It is to be understood that such descriptions are merely illustrative of the features and advantages of the present invention and are not intended to limit the scope of the present invention as claimed.
The utility model discloses a modular battery module submergence formula liquid cooling system of intercommunication each other, include: battery module and cooling module.
Battery pack module package: the device comprises a battery 1, a box body 2, a box body upper cover plate 3, fins 4, a liquid phase communicating pipe 5, a gas phase communicating pipe 6 and a fluorinated liquid 8; wherein the battery 1 is positioned at the bottom of the box body 2; the fins 4 are arranged on the lower surface of the upper cover plate 3 of the box body and used for strengthening heat exchange; the liquid phase communicating pipe 5 is connected to the lower positions of the two sides of the box body 2, the gas phase communicating pipe 6 is connected to the upper positions of the two sides of the box body 2, and the liquid phase communicating pipe and the gas phase communicating pipe are respectively used for balancing the liquid level of the fluorinated liquid 8 and the vapor pressure of the fluorinated liquid in different battery modules; when the battery module starts to generate heat during working, the temperature rises gradually, the heat generated by the battery module is taken away by the filled fluorinated liquid, and when the temperature of the fluorinated liquid does not reach the boiling point, the fluorinated liquid absorbs the heat generated by the battery module by utilizing sensible heat; when the surface temperature of the battery module rises to be higher than the boiling point of the fluorinated liquid, the fluorinated liquid starts to boil, the fluorinated liquid steam generated by boiling is condensed on the surface of the fin 4, and the condensed heat is taken away by the cooling working medium in the cooling coil 7 positioned in the upper cover plate 3 of the box body.
The cooling module includes: the cooling coil 7, the compressor 9, the condenser 10 and the throttle valve 11 are used for circulating the refrigerant; the cooling coil 7, the compressor 9, the condenser 10 and the throttle valve 11 are connected in sequence through pipelines to form a ring. Fig. 1 is a schematic diagram of an immersion type liquid cooling system of interconnected modular battery modules, and in this example, 1 set of 6 batteries is taken as an example to explain the whole system. The battery 1 comprises a cylindrical battery, a square battery and a soft package battery. The box body 2 and the box body upper cover plate 3 are sealed by pressing a gasket, wherein the box body upper cover plate 3 is provided with a liquid filling pipe (not shown in the drawing) for vacuumizing the box body 2 and filling the fluorinated liquid.
The fluorinated liquid 8 is an insulating flame-retardant liquid and has a boiling point of 0-50 ℃ under 1 atmosphere, and in the example, HFE-7000 fluorinated liquid produced by a 3M formula is used, and has a boiling point of 34 ℃, so that the fluorinated liquid has good dielectric properties and excellent flame retardance. The cell should be fully or partially immersed in the fluorinated liquid, in this example the cell is fully immersed in the fluorinated liquid.
As shown in fig. 2, is an oblique view of the battery pack case. Wherein, fin 4 can increase the area of contact of cold source and fluorination liquid steam, improves the condensation rate of fluorination liquid steam. The fins used in this example were metal aluminum fins coated with a superhydrophobic coating on the outer surface, in this example a teflon coating, and after the surface had dried, the surface contact angle was measured to be greater than 150 degrees. Therefore, the fluorizated liquid is condensed in a bead-shaped manner on the surface of the fluorizated liquid, and the condensation heat transfer efficiency is greatly improved.
As shown in fig. 1, which is a front view of a battery box, a liquid phase communicating pipe 5 connects each battery box in series, and the fluorinated liquid can circulate inside the battery box, so that the liquid level height of the fluorinated liquid in each battery box is kept consistent by using the communicating vessel principle. In this example, the liquid phase communicating pipe 5 is a PVC transparent wire hose, and is connected to the tank by a strong metal clamp to achieve sealing. The gas phase communicating pipe 6 connects the battery boxes in series, and the fluorination liquid steam can circulate in the gas phase communicating pipe, so that the fluorination liquid steam pressure in each battery box is kept consistent, and the boiling point of the fluorination liquid in each box is kept consistent. In this example, the gas-phase communicating pipe 6 is a PVC transparent wire hose, and is connected to the tank by a strong metal clamp to achieve sealing.
As shown in fig. 1, the battery module pack: the device comprises a battery 1, a box body 2, a box body upper cover plate 3, fins 4, a liquid phase communicating pipe 5, a gas phase communicating pipe 6 and a fluorinated liquid 8. When the cell begins to operate, the cell will continue to generate heat, which will be absorbed by the filled fluorinated liquid. In the initial stage of the operation of the battery, the temperature of the fluorinated liquid does not reach the boiling point, and sensible heat is utilized to absorb heat generated by the battery during the operation. Along with the continuous progress of battery heat production, battery surface temperature reaches boiling point and boiling point more than gradually, and the liquid of fluoridizing begins the boiling, and the liquid steam of fluoridizing that the boiling produced condenses on the fin surface, and the heat that the condensation was given off is given external environment under the effect of cooling module.
As shown in fig. 1, the cooling module includes: cooling coil 7, compressor 9, condenser 10 and throttle valve 11. The working medium circulating in the cooling module is a refrigerant, and the refrigerant adopted in the example is R134 a. The refrigerant absorbs heat released by the condensation of the fluorinated liquid vapor on the surfaces of the fins 4 in the cooling coil 7 to be vaporized, and the vaporized refrigerant is compressed by the compressor 9 and liquefied in the condenser 10 to transfer the heat to the external environment. The liquefied refrigerant passes through the throttle valve 11 and then returns to the cooling coil 7, thereby completing the circulation of the refrigerant.
Because the temperature difference between different regions and different seasons in the same region is large, for example, the temperature of tropical regions is high all the year round, if no heat preservation and insulation measures are adopted, the fluorinated liquid in the box body is caused to boil explosively, and the heat dissipation is influenced. For this purpose, it is necessary to apply a thermal insulation layer on the outer surface of the case, and in this example, a thermal insulation aerogel (not shown in the drawings) is applied on the outer surface of the battery case. Meanwhile, in a severe cold area, the heat-insulating layer can effectively inhibit the temperature of the battery from being reduced, so that the cold start problem of parking in a short time is avoided, and the service life of the battery is prolonged.
To sum up, the utility model discloses a modular battery module submergence formula liquid cooling system of intercommunication each other. Each battery module is connected with the other battery module through a gas-liquid communicating pipe, so that the vapor pressure of the fluorinated liquid in different battery modules is equal, and the uniformity of the temperature among different battery monomers is ensured. The phase change of the liquid is fully utilized to carry out heat extraction and heat dissipation, so that the thermal resistance in the whole heat transfer process is reduced to the minimum, and the energy consumption of the system is greatly reduced.
The technical solutions and advantages of the present disclosure have been described in detail with reference to the specific examples, and it should be understood that the above description is only exemplary of the present disclosure, and is not intended to limit the present disclosure. The sizes and shapes of the various elements in the drawings are not to be considered as reflecting actual sizes and proportions, but are merely representative of the contents of the present example.
