Example 1:
in order to better illustrate the present invention, the present embodiment provides a new energy vehicle having a thermal management system according to the present invention. Specifically, the method comprises the following steps:
as shown in fig. 1, in the thermal management system of the embodiment, a battery compartment 2 and an air conditioning system 1 are thermally coupled together, one or more battery boxes 22 are arranged in the battery compartment 2, one or more battery units 221 are arranged in the battery boxes 22, a first heat exchanger 23 is arranged in a cavity of the battery compartment 2, and multi-stage cooling is formed among the air conditioning system 1, the battery compartment 2 and the heat exchanger.
As shown in fig. 1, the cooling medium first obtains cooling capacity from the evaporator of the air conditioning system 1, and then is sent to each battery box 22 in the battery compartment 2, and the cooling medium cools the battery unit 221 of the battery box 22 in the battery box 22 by using the cooling capacity obtained from the air conditioning system 1, and then enters the heat exchanger in the battery compartment 2 to absorb heat in the battery compartment, and finally leaves the battery compartment 2. This realizes stepwise utilization of energy and stepwise cooling of the battery unit 221, the battery box 22, and the battery compartment 2 by the cooling medium. Preferably, the cooling medium directly enters the battery box 22 in the battery compartment 2 from outside the battery compartment, and the battery unit 221 in the battery box is formed with a cooling medium channel to absorb heat generated by the battery unit 221, so that not only the space is reduced, but also the heat exchange effect is improved.
Preferably, the thermal management system is also provided with a sensor and a controller 3; the sensors include a temperature sensor 222 arranged in the battery box 22 and a temperature and humidity sensor 21 in the battery compartment 2, and the controller 3 controls the cooling capacity of the cooling medium obtained from the air conditioning system 1 and the use of the drying device 4 according to the temperature in the battery box 22 and the temperature and humidity in the battery compartment 2.
The cooling medium of the present invention may be air, inert gas (such as nitrogen, carbon dioxide, etc.) or refrigerant (insulation performance meets the standard), and preferably, the cooling medium used in this embodiment is carbon dioxide. In order to ensure the safety and the flexibility, a closed cooling medium circulating system is formed among the air conditioning system 1, the battery compartment 2 and the heat exchanger, and the cooling medium returns to the air conditioning system 1 after flowing out of the battery compartment 2, so that the cyclic utilization of the cooling medium is realized.
In the actual working process, the air conditioning system 1 and the battery unit 221 work simultaneously, and carbon dioxide sent by the air conditioning system 1 enters the battery box 22 to exchange heat with the battery unit 221 in the battery box. A temperature sensor 222 and a temperature and humidity sensor 21 are respectively arranged in each battery box 22 and each battery cabin 2, so as to monitor the temperature and the humidity in real time and feed back the temperature and the humidity to the controller 3, and the controller 3 adjusts the temperature and the humidity of the cooling medium output by the air conditioning system 1. If the temperature in the battery compartment 2 is high and the humidity is high, condensed water is easily formed on the surface of the cold battery box 22, which endangers the safety of the battery, so that the cooling medium discharged from the battery box 22 can continuously absorb heat in the battery compartment 2 through the first heat exchanger 23, and then returns to the air conditioning system 1 after flowing out of the battery compartment 2.
Further preferably, a drying device 4 for drying the cooling medium is connected between the air conditioning system 1 and the battery box 22. Before carbon dioxide enters into battery box 22, earlier through drying device 4 to improve coolant's quality, avoid appearing the condensate water among the heat transfer system and then influence electric safety, be favorable to keeping the dryness factor and the cleanliness in battery box 22, thereby promote system stability.
It is further preferable that the battery compartment 2 and the battery box 22 as well as the heat exchange flow channel and the heat exchange tube are internally provided with a thermal insulation material to prevent the cooling amount in the cooling medium channel from leaking and prevent the external water vapor from entering the battery unit 221, thereby ensuring the safety performance of the battery. And if the heat preservation and moisture insulation effect of the battery box 22 is good enough, the heat exchange process of the first heat exchanger 23 and the cooling medium in the battery box 2 can be omitted, namely, the carbon dioxide discharged from the battery box 22 directly returns to the air conditioning system 1, but in order to further improve the effective cooling of the battery box 2 and the battery box 22 in the battery box 2 by the heat management system, the heat exchanger is preferably arranged in the battery box cavity 2.
It is also further preferable that a cavity is formed in the bulkhead of the battery compartment 2 as a heat exchange flow path for absorbing heat in the battery compartment, thereby constituting the second heat exchanger. The second heat exchanger can replace the first heat exchanger 23, or a primary heat exchange can be further added on the basis of the first heat exchanger 23, that is, after the cooling medium comes out of the first heat exchanger 23, the cooling medium can also be not directly sent back to the air conditioning system 1, but enters the second heat exchanger in the cabin wall of the battery cabin 2 to continuously absorb heat and then returns to the air conditioning system 1. Therefore, the multiple effects of heat preservation, moisture insulation and energy conservation can be improved.
In summary, the thermal management system of the new energy vehicle provided by the embodiment takes carbon dioxide as a cooling medium (certainly, carbon dioxide is not limited, and other inert gases are also available), so that heat exchange in the power battery box of the vehicle is enhanced, temperature in the battery box and the temperature in the battery cabin can be kept constant to the greatest extent, and the cycle life of the power battery is prolonged; meanwhile, the energy efficiency of the heat management system is improved by utilizing the principle of energy step, and the energy efficiency of the whole vehicle is further improved.
The invention is not only limited to new energy vehicles, but also can be used in other occasions with power batteries and air conditioning systems, such as low-temperature environment combining power batteries and central air conditioning systems.
Example 2:
in this embodiment, the cooling medium is air. As shown in fig. 2, compared to example 1 in which carbon dioxide is used as a refrigerant, the air conditioning system 1, the battery compartment 2, and the heat exchanger of example 2 in which air is used as a cooling medium form open cooling therebetween. The air is vented directly to the atmosphere after exiting the battery compartment 2.
The rest is the same as example 1.
