The type of the electromagnetic water valve 171 of this embodiment may be ZBS-DN8-10, and the stainless steel material can prevent corrosion, which is specifically selected according to the actual use requirement, and this embodiment is not specifically limited.
In another embodiment, referring to fig. 3, taking the first heat-conducting plate 13 as an example, the heat pipe may be disposed in the middle of the cavity structure 100, so that the cavity structures 100 at both ends of the first heat-conducting plate 13 can provide buffering and converging functions for the coolant volatile liquid.
In one embodiment, referring to fig. 1, a heat dissipation fin 121 is further disposed on a side of the second liquid cooling plate 12 away from the first liquid cooling plate 11, the heat dissipation fin 121 can be in direct contact with air outside the single battery 200, a contact area between the temperature control device 1 and the air outside the single battery 200 can be increased, heat exchange efficiency between air in an external environment and the temperature control device 1 is enhanced, and thus a heat exchange effect is improved.
Referring to fig. 5, the embodiment of the present invention further provides a battery module 2, which includes a housing 21, a single battery 200, and the temperature control device 1, wherein the temperature control device 1 is connected to the single battery 200 and is disposed inside the housing 21, and the bottom of the temperature control device 1 is in direct contact with the bottom of the housing 21. The temperature control device 1 in this embodiment may have the same structure and achieve the same effect as the temperature control device 1 in the above embodiment, and details are not repeated in this embodiment.
In particular, referring to fig. 6, the second liquid cooling plate 12 may be integrated into the housing 21, so as to simplify the structure of the battery module 2, further reduce the size, and improve the heat exchange efficiency between the temperature control device 1 and the housing 21.
With further reference to fig. 6, the lower surface of the casing 21 may be provided with heat dissipation fins 121, since the bottom of the temperature control device 1 directly contacts with the bottom of the casing 21, the heat exchange efficiency between the air of the external environment and the temperature control device 1 can be enhanced, thereby improving the heat exchange effect.
In addition, referring to fig. 7, the embodiment of the present invention further provides a vehicle 3, which includes a vehicle body 31, and the battery module 2, where the battery module 2 is disposed at the bottom of the vehicle body 31. The temperature control device 1 and the battery module 2 in this embodiment have the same structure and achieve the same effect as the temperature control device 1 and the battery module 2 in the above embodiments, and the description thereof is omitted.
Preferably, the lower surface of the housing 21 of the battery module 2 may be provided with heat dissipation fins 121, and the heat dissipation fins 121 can directly exchange heat with the air outside the single battery 200, and can also enhance the heat exchange efficiency between the air in the external environment and the temperature control device 1, thereby improving the heat exchange effect. Generally, the more the vehicle 3 travels and the more the consumed electric energy is, the more the heat dissipated by the unit battery 200 due to the conversion loss is, but since the heat dissipation fins 121 can contact the air flowing outside the vehicle body 31 rapidly, the heat dissipated by the unit battery 200 can be transferred to the air outside the vehicle body 31 rapidly after being transferred to the heat dissipation fins 121, so that the heat dissipation rate of the vehicle 3 is proportional to the traveling speed within a certain range.
In particular, during the operation of the vehicle 3, the temperature of the single battery 200 is continuously increased, and when the temperature of the single battery 200 is low, the heat dissipated by the single battery 200 can be absorbed by using the heat conduction layer 18 made of the phase change material and the first liquid cooling plate 11, so that the heat dissipation requirement of the single battery 200 can be met. However, when the temperature of the single battery 200 reaches a certain critical point, the heat dissipation requirement of the single battery 200 is not satisfied by the heat conduction layer 18 and the first liquid cooling plate 11, and therefore, the second liquid cooling plate 12 capable of exchanging heat with the air of the external environment can be accessed to provide further heat dissipation.
