The evaporation branch heat pipe 42 is provided with fins for accelerating heat dissipation. When the hot air after cooling the battery passes through the evaporation branch heat pipe 42, the liquid working medium in the evaporation branch heat pipe evaporates, and the steam flows to the condensing device 44 through the outlet heat pipe 43. The condensing unit 44 is disposed at the top and above the inlet heat pipe and is coupled to an external cooling system. In the condensing device 44, the gaseous working medium is condensed and changed into liquid working medium again, heat is transferred to an external cooling system, then the liquid working medium flows back to the inlet heat pipe by gravity or the action of the micro circulation pump, and is distributed to the evaporation branch heat pipe by the inlet heat pipe, and enters the next circulation. Preferably, the inner surface of the heat pipe assembly can be provided with a liquid suction core, so that the reflux stability of the liquid working medium is further ensured, and the liquid suction core is one or a combination of a plurality of sintered powder, a wire mesh, foam metal, a nano coating and a micro groove.
The following details this energy storage heat pipe air conditioner, specifically, this energy storage heat pipe air conditioner includes confined shell 1, and the inside of shell 1 has 2 independent installation battery package's cavity, all installs the cylinder battery in the battery cluster 2 in each battery package, forms the passageway of air reflux between 2 independent installation battery packages, and in other embodiments, the battery is not limited to the cylinder battery. The same applies to square cells. The following section of this patent describes a cylindrical battery arrangement.
The back of the corresponding battery compartment of the shell 1 is provided with a heat pipe evaporator assembly 4, the heat pipe evaporator assembly 4 is vertically arranged, and a heated part of the heat pipe evaporator assembly 4 is arranged on the back of the battery pack. The baffle 3 is used for enabling wind to pass through the heat pipe evaporator as much as possible, and enhancing heat exchange. The coolant inlet is connected with the micro-circulation pump 47, and the coolant outlet is connected with the cooling system. The cooling system can be arranged at the back of the energy storage station or outside the energy storage station according to the actual application scene, and the cooling system is higher than the micro circulating pump 47.
As shown in fig. 3 and 4, the energy storage station battery is composed of 2 battery packs, and the total of the 2 battery packs is 36 battery clusters 2, but is not limited to 36 battery clusters. The single battery cluster 2 is composed of a plurality of batteries, a shell, a fan 22, an air inlet and the like, and the battery form in the battery cluster 2 is not limited to a cylindrical battery in the patent, and is also applicable to a blade battery. Each battery cluster 2 has two fans 22 for creating a through-flow air duct while ensuring that the through-flow air duct cannot be created due to failure of a single fan 22. The cold air from the air inlet is heated by the battery cluster 2, and then radiates heat to the external space under the action of the fan 22, and the hot air conducts the heat to the heat pipe evaporator to become cold air, and flows back to the air inlet, so that the cold air circularly flows. The closed battery cluster 2 structure prevents hot air generated by the battery clusters 2 from flowing between the battery clusters 2, and is beneficial to heat dissipation.
In the embodiment shown in fig. 5, after the working medium is returned from the outlet heat pipe 43 to the condensing device 44, the working medium is cooled by the condensing device 44 and then optionally returned from the liquid return main 45 or the liquid return bypass 46 to the inlet heat pipe, and the selection method is as follows.
Specifically, the heat pipe evaporator assembly 4 further includes a micro circulation pump 47, the micro circulation pump 47 is disposed on the working medium liquid return main circuit 45 of the heat pipe evaporator assembly 4, the liquid return main circuit 45 of the heat pipe evaporator assembly 4 further includes a liquid return bypass 46 connected in parallel with the liquid return main circuit 45, and the micro circulation pump 47 is disposed on the liquid return main circuit 45; when the temperature of the battery in the battery pack is higher than the threshold value, the micro circulation pump 47 is started and the circulation of the working medium is accelerated.
The battery pack is internally provided with a temperature sensing component and a temperature control system, the temperature sensing component is used for detecting the temperature of the battery in the battery pack, and the temperature sensing component and the micro circulating pump 47 are both in signal connection with the temperature control system. When the temperature of the battery in the battery pack rises to a set value, the temperature control system gives an instruction to the micro circulating pump 47, the micro circulating pump 47 is started, and at the moment, the working medium returns to the inlet heat pipe 41 from the liquid return main path 45, so that the circulation speed of the working medium is increased, and the heat dissipation is accelerated; when the temperature of the battery in the battery pack is lower than the threshold value, the micro circulating pump 47 is started to be closed, and the working medium returns to the heated part of the heat pipe evaporator assembly 4 through the liquid return bypass 46.
The micro circulation pump 47 is a fluorine pump or a two-phase flow pump. The connection between the micro circulation pump 47 and the cooling system outlet and inlet heat pipes is by heat pipe connection. When the heat dissipation capacity of the battery is small and the temperature is low, namely, the temperature of the battery in the battery pack is lower than the threshold value, the working medium can flow back to the inlet heat pipe 41 through the liquid return bypass 46. When the heat dissipation capacity of the battery is large and the temperature is high, the temperature of the battery in the battery pack is higher than the threshold value, the micro circulating pump 47 is started, working medium returns to the inlet heat pipe 41 from the liquid return main circuit 45, the circulation speed of the coolant is accelerated, and the heat dissipation capacity is accelerated.
In the heat pipe evaporator assembly 4, the working medium entering from the inlet heat pipe 41 is quickly vaporized into steam, the steam enters the outlet heat pipe 43 through the heat exchange enhancement of the branch heat pipe 42 and flows into the cooling system, the cooling system condenses and releases heat and then is changed back into liquid again, before the liquid returns to the inlet of the micro circulating pump 47 under the action of gravity, whether the liquid flows back to the inlet heat pipe 41 under the action of the micro circulating pump 47 or the natural gravity according to the temperature of air in the battery pack is selected under the action of the temperature control system, and the liquid enters the next cycle.
The condensing device 44 is combined with an external cooling system, and the condensing device 44 of the heat pipe evaporator assembly is used for condensing gaseous working medium inside the heat pipe, and the combination of the condensing device 44 and the external cooling system specifically comprises the following three forms. An extended embodiment of the cooling system is described in detail below by way of examples.
Example 1
As shown in fig. 6, in the first embodiment of the cooling system of the present application, the condensing device 44 is a gas-gas indirect heat exchanger, where the fan 22 is disposed, and the heat pipe working medium is cooled by air cooling.
In this embodiment, only the heat pipe evaporator assembly is used as the heat exchanger and the fan 22 as the basic heat dissipation mode, and the heat pipe air conditioner has a better heat dissipation effect under this working condition.
Example 2
In this embodiment, the energy storage heat pipe air conditioner in embodiment 1 is used as a basis, and the cooling system in this embodiment cools the working medium inside the heat pipe in a liquid cooling manner, thereby adopting a cooling tower manner.
As shown in fig. 7, the condensing unit 44 acts as a gas-liquid indirect heat exchanger, and the cooling system further includes an external cooling tower. The cooling tower is used for taking away part of heat by means of circulation of chilled water in the heat exchanger. In this embodiment, the cooling tower is connected to the heat exchanger through the chilled water inlet line and the chilled water outlet line, i.e., chilled water is introduced into the heat exchanger. After passing through the heat exchanger, the heat of the heat pipe working medium is transferred to circulating chilled water, the chilled water carries the heat to a cooling tower, and the cooling tower dissipates the heat to the external environment in a natural air cooling mode so as to fully utilize a natural cold source.
Example 3
In areas with hotter climate, the natural cold source is utilized very limited, and the embodiment is improved on the basis of the embodiment 2.
As shown in fig. 8, a refrigeration system is provided in this embodiment. The condensing device is a water-cooled plate and still serves as a gas-liquid indirect heat exchanger. After the working medium in the heat pipe passes through the heat exchanger, heat is transferred to chilled water. Finally, heat is dissipated to the outside environment by the refrigeration system. The refrigeration system can reduce the temperature of chilled water to a specific temperature, which can be lower than ambient temperature, to achieve rapid heat dissipation.
In the above three embodiments, the sensing components are disposed in the battery pack, and are used for detecting the temperature of the battery in the battery pack, and when the temperature of the battery rises to a set value, the micro-circulation pump is turned on, so as to promote the reflux of the working medium of the heat pipe, and at the same time, accelerate the circulation speed of the cooling medium (air in embodiment 1 and chilled water in embodiments 2 and 3) at the cooling system end. Otherwise, the working medium in the heat pipe flows back to the inlet heat pipe through the bypass 46 by gravity.
The foregoing is merely exemplary of the present application, and those skilled in the art can make many variations in the specific embodiments and application scope according to the spirit of the present application, as long as the variations do not depart from the spirit of the application.
