[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0033] like Figs. 1-3 As shown, this utility model discloses a thermal management system for charging piles. The thermal management system includes: a radiator, which includes several heat exchange channels 1 disposed on electrical components 2 inside the charging pile, and heat exchange liquid flowing through the heat exchange channels 1. The heat exchange channels 1 are integrated channels; a filter assembly, which is disposed at the inlet of the heat exchange channels 1; and a detection assembly, which includes several humidity sensors 4 disposed on the heat exchange channels 1.
[0034] The thermal management system of this utility model includes a radiator, which comprises several heat exchange channels 1 installed on the electrical components 2 inside the charging pile. Heat exchange fluid flows through the heat exchange channels 1, and the flow of the heat exchange fluid dissipates excess heat generated by the operation of the electrical components 2, thus cooling the charging pile. The heat exchange channels 1 are integrated channels, meaning they only have two joints at both ends. This reduces the number of joints in the heat exchange channels 1, lowers the risk of heat exchange fluid leakage during operation, and reduces the maintenance cost of the thermal management system. A filter assembly at the inlet of the heat exchange channels 1 filters the heat exchange fluid flowing into the channels, trapping any impurities at the inlet and reducing the risk of blockage due to impurity accumulation, which could reduce the cooling effect of the charging pile. Operators can determine whether a leak has occurred in the heat exchange channels 1 by observing the humidity sensor 4 on each channel, allowing for timely repair or replacement, further reducing the maintenance cost of the thermal management system and ensuring its heat exchange performance. In short, this utility model achieves good cooling performance for the charging pile while reducing the operating and maintenance costs of the thermal management system, thus lowering overall cooling costs.
[0035] The electric element 2 mentioned in the present application refers to the electric element 2 in the charging pile that generates heat. The heat exchange channel 1 is essentially a shell in which heat exchange liquid flows. According to the working condition, the heat exchange liquid can flow in the heat exchange channel 1 through its own gas-liquid change or under the action of a pump or the like. For example, when the electric element 2 generates less heat, the boiling point of the heat exchange liquid is lower than the heat generation temperature of the electric element 2. The inlet and outlet of the heat exchange channel 1 are arranged from top to bottom. The upper part of the heat exchange channel 1 extends out of the charging pile, and the part of the heat exchange channel 1 extending out of the charging pile is provided with heat dissipation fins. In this way, when the electric element 2 is not running, i.e. does not generate heat, the heat exchange liquid is in a liquid state and is located in the lower part of the heat exchange channel 1. When the heat generated by the electric element 2 is higher than the boiling point of the heat exchange liquid, the heat exchange liquid changes from a liquid state to a gaseous state and rises to the top of the heat exchange channel 1. The heat is dissipated to the outside through the heat dissipation fins, and a fan can also be arranged towards the heat dissipation fins to quickly remove the heat dissipated by the heat exchange gas through the heat dissipation fins (the heat exchange gas refers to the gaseous heat exchange liquid), so that the heat exchange gas is quickly cooled. After the heat exchange gas is cooled, it changes from a gaseous state to a liquid state and then falls to the bottom of the heat exchange channel 1 under the action of gravity. At this time, the heat exchange liquid realizes the flow in the heat exchange channel 1 through the change between the gas phase and the liquid phase. When the electric element 2 generates more heat, the shell is connected to the storage tank through the liquid inlet pipe and the liquid return pipe. The storage tank stores heat exchange liquid that can remove the heat generated by the electric element 2. The liquid inlet pipe or the liquid return pipe is provided with a delivery pump to realize the circulation of the heat exchange liquid between the heat exchange channel 1 and the storage tank. The storage tank can be a cooling tower to quickly cool the heated heat exchange liquid, or the storage tank is connected to a refrigeration device, such as a compression refrigeration machine including a compressor, a condenser, an expansion valve and an evaporator. The refrigeration device is a prior art and will not be described here. The heat exchange liquid can be water or other liquid that can remove the heat generated by the electric element 2.
[0036] The heat management system in the present application is arranged to avoid the electric element 2 in the charging pile to ensure the heat dissipation effect of the charging pile without affecting the normal operation of the charging pile.
[0037] The shell of the heat exchange channel 1 has good thermal conductivity, so that the heat generated by the electrical element 2 is smoothly transmitted to the heat exchange liquid in the heat exchange channel 1. Alternatively, a heat-conducting layer can also be provided between the shell of the heat exchange channel 1 and the electrical element 2 to ensure effective transmission of the heat generated by the electrical element 2. The heat-conducting layer can be a structure such as heat-conducting glue that has good thermal conductivity. The integrated channel refers to a channel that is integrally formed, rather than a channel that is formed by connecting several channels together. This reduces the number of channel joints and reduces the risk of leakage of the heat exchange channel 1. However, the structure of the integrated heat exchange channel 1 is fixed, and the flow rate, path, etc. are difficult to adjust, which makes it difficult to optimize the heat exchange efficiency under different working conditions, and even forms a flow dead zone. Therefore, the utility model improves the turbulence of the heat exchange liquid and reduces the flow components of the heat exchange liquid by setting the turbulence assembly and the circular arc transition area at the corner, thereby improving the heat exchange efficiency and reducing the formation of flow dead zones.
[0038] The filter assembly can be a plurality of filter screens 3 arranged at the inlet. The filter holes of the filter screens 3 need to be large enough to effectively retain impurities in the heat exchange liquid and not hinder the effective components in the heat exchange liquid from entering the heat exchange channel 1. In order to reduce the weakening of the flow rate of the heat exchange liquid by the filter screens 3 and reduce the power consumption of the delivery pump, the utility model sequentially and intermittently arranges a plurality of filter screens 3 at the inlet along the flow direction of the heat exchange liquid. The pore size of the filter holes of the filter screens 3 gradually decreases along the flow direction of the heat exchange liquid. For example, when a first filter screen, a second filter screen and a third filter screen are sequentially arranged along the flow direction of the heat exchange liquid, the pore size of the first filter screen is larger than that of the second filter screen, and the pore size of the second filter screen is larger than that of the third filter screen. This makes the heat exchange liquid pass through the filter screens 3 step by step, so that the flow rate of the heat exchange liquid decreases less, reducing the problem that the heat exchange liquid directly passes through the filter screen 3 with small filter holes and severely reduces the flow rate of the heat exchange liquid, thereby reducing the problem of increasing the power consumption of the delivery pump to ensure the flow rate of the heat exchange liquid. The filter screens 3 and the heat exchange channel 1 can be detachably connected, so as to realize quick replacement of the filter screens 3. The filter screens 3 and the heat exchange channel 1 can be clamped or bolted.
[0039] And, the humidity sensor 4, the alarm in the utility model are all connected with the controller signal, the controller is used for starting the alarm when the humidity sensor 4 detects the leakage amount of heat exchange channel 1 reaches the set value;The alarm can be specifically acoustic and light alarm, when the humidity sensor 4 detects the leakage amount of heat exchange channel 1 reaches the set value, i.e. set leakage amount, the humidity sensor 4 will signal feedback to the controller, the controller starts the alarm, and reminds the operator to replace heat exchange channel 1 in time. However, since heat exchange channel 1 is connected with electrical element 2 at least one side, and if the humidity sensor 4 is arranged on the side connected with electrical element 2, the heat dissipation area of electrical element 2 and heat exchange channel 1 will be reduced, so the present application is provided with an isolation layer outside heat exchange channel 1, the isolation layer includes the heat conduction area 6 and the water storage area 5 arranged at intervals, the heat exchange liquid that may leak in heat exchange channel 1 is stored in the water storage area 5, to prevent the heat exchange liquid leaked in heat exchange channel 1 from causing electrical accident, the heat generated by electrical element 2 is ensured to be smoothly conducted to the heat exchange liquid in heat exchange channel 1 through the heat conduction area 6, and is taken away by the heat exchange liquid;The heat conduction area 6 and the water storage area 5 are independently arranged, and specifically can be separated by a partition plate, so as to prevent the water in the water storage area 5 from affecting the heat conduction performance of the heat conduction area 6;The water storage area 5 can be specifically a plurality of cavities, and the heat conduction area 6 can be specifically a heat-conducting adhesive or other material with heat conduction performance.
[0040] And / or, heat exchange channel 1 has a corner, and an arc transition area is arranged at the corner, so that the sharp change of the shape of heat exchange channel 1 is reduced, so that the heat exchange liquid can flow more smoothly in heat exchange channel 1, thereby reducing the problem that the flow rate of the heat exchange liquid is greatly reduced due to sharp change of direction, and ensuring the flow rate of the heat exchange liquid and the heat dissipation effect of the heat management system;And / or, heat exchange channel 1 includes a first channel and a second channel arranged in sequence along the flow direction of the heat exchange liquid and connected, the first channel and the second channel are gradually changing diameter channels, and the diameter of the first channel is greater than that of the second channel;The first channel and the second channel make the flow cross section of the heat exchange liquid gradually smaller, thereby improving the flow rate of the heat exchange liquid, so that the heat exchange liquid can timely take away the heat generated by electrical element 2, and ensure the heat dissipation effect of the heat management system.
[0041] And / or, a liquid inlet pipe is arranged at the inlet of heat exchange channel 1, and a liquid return pipe is arranged at the outlet of heat exchange channel 1, the first included angle between the liquid inlet pipe and heat exchange channel 1 and the second included angle between the liquid return pipe and heat exchange channel 1 are both less than 90°, through the above liquid inlet pipe and liquid return pipe, the problem that the flow rate of the heat exchange liquid is reduced due to sudden change of flow direction when the heat exchange liquid enters and leaves heat exchange channel 1 is reduced, so that the heat exchange liquid can pass through heat exchange channel 1 at a higher flow rate, and timely take away the heat generated by electrical element 2.
[0042] The heat management system further comprises a turbulence assembly arranged in the heat exchange channel 1, the turbulence assembly comprising a plurality of baffles 7 and / or turbulence columns 8 and / or turbulence grooves arranged in the heat exchange channel 1. Further, a plurality of baffles 7 are arranged in the heat exchange channel 1 along the flow direction of the heat exchange liquid, all the baffles 7 and the heat exchange channel 1 form flow channels for the flow of the heat exchange liquid, a plurality of turbulence columns 8 and a plurality of turbulence grooves are arranged in the flow channels, the turbulence columns 8 and the turbulence grooves are arranged in a staggered manner, and the turbulence columns 8 and the turbulence grooves can be arranged on the same side of the shell or on opposite sides of the shell. The baffles 7 prolong the flow path of the heat exchange channel 1 from the inlet to the outlet, prolong the contact time of the heat exchange liquid and the electrical components 2, so that the heat exchange liquid can fully take away the heat generated by the electrical components 2, the turbulence grooves and the turbulence columns 8 enhance the disturbance of the heat exchange liquid and accelerate the turbulent state of the heat exchange liquid, thereby improving the basic efficiency of the heat exchange liquid and the electrical components 2 and improving the heat dissipation efficiency of the heat management system.
[0043] Alternatively, the turbulence assembly can not have the above structure, in which case the turbulence assembly comprises a turbulence plate arranged in the heat exchange channel 1, the turbulence plate is arranged along the flow direction of the heat exchange liquid, a plurality of through holes are arranged on the turbulence plate, and the turbulence plate is equivalent to a perforated metal plate. This increases the degree of disorder of the heat exchange liquid in the heat exchange channel 1, so that the heat exchange liquid flows in the irregular flow channels formed between the turbulence plate and the heat exchange channel 1 and is in a state of continuous splitting and merging, thereby improving the heat dissipation efficiency of the heat management system. The turbulence plate can be arranged in the heat exchange channel 1 by bolts, and there is a gap between the turbulence plate and the heat exchange channel 1.
[0044] Alternatively, the turbulence assembly comprises an oscillation member, the oscillation member applies a first force to the heat exchange liquid in the heat exchange channel 1, the first force causes the heat exchange liquid to oscillate; the oscillation member has various forms of arrangement: for example, the heat exchange channel 1 is an elastic heat exchange channel 1, the oscillation member comprises a vibration motor connected in transmission with the heat exchange channel 1, the vibration motor can be started periodically, the vibration motor drives the heat exchange channel 1 to vibrate, so that the heat exchange liquid oscillates in the heat exchange channel 1, destroys the boundary layer between the heat exchange liquid and the heat exchange channel 1, thereby significantly improving the heat transfer capacity of the heat exchange channel 1; and a buffer layer is arranged between the heat exchange channel 1 and the electrical element 2, the buffer capacity of the electrical element 2 is improved through the buffer layer, preventing the vibration motor from causing damage to the electrical element 2, the buffer layer can be a damping pad made of damping material such as polyurethane; alternatively, the oscillation member comprises a plurality of impellers 9 arranged in the heat exchange channel 1, the impellers 9 can be fixed in the heat exchange channel 1 through a support, the support and the heat exchange channel 1 have a large enough gap, so that the support does not greatly hinder the flow of the heat exchange liquid, the axial direction of the impeller 9 is parallel to the axial direction of the heat exchange channel 1, the impeller 9 can be driven to rotate by the heat exchange liquid, or can also be driven to rotate by a driving device such as a rotary motor; when the impeller 9 is driven to rotate by the heat exchange liquid, the heat exchange liquid generates self-excited oscillation pulse jet flow when passing through the impeller 9, thereby strengthening the heat exchange efficiency. When the impeller 9 rotates, there is a difference in flow rate of the heat exchange liquid before and after the impeller 9. This periodic change in flow rate causes the heat exchange liquid to generate pulse pressure waves and vortices. The pressure waves propagate in the heat exchange channel 1, thereby inducing periodic oscillation of the heat exchange liquid. The vortices can improve the heat exchange efficiency between the heat exchange liquid and the electrical element 2, reduce flow dead zones, and avoid heat accumulation. The periodic pressure fluctuations generated by the impeller 9 can prevent particles and sediments in the fluid from accumulating in the pipeline. The periodic flow changes cause the particles to move constantly, reducing the risk of clogging and deposition.
[0045] The heat exchange channel 1 is arranged in a vertical direction, and the inlet and outlet of the heat exchange channel 1 are arranged from top to bottom. This allows the heat exchange liquid to flow along the heat exchange channel 1 under the action of gravity, thereby reducing the energy consumption of the delivery pump.
[0046] The heat exchange channel 1 comprises a first channel group and a second channel group arranged in sequence along the flow direction of the heat exchange liquid and connected in communication. The first channel group and the second channel group each comprise a plurality of first channels arranged in parallel. The series connection of the first channel group and the second channel group allows the heat exchange liquid in the first channel group and the second channel group to have a high flow rate. The parallel arrangement of the first channels reduces the pressure loss in the first channels, improves the flow of the heat exchange liquid, and improves the heat dissipation efficiency of the heat management system.
[0047] And / or, the heat exchange channel 1 comprises alternating hydrophilic layer 10 and hydrophobic layer 11, the hydrophilic layer 10 and the hydrophobic layer 11 can be alternately arranged along the axial and / or ring direction of the heat exchange channel 1, when the hydrophilic layer 10 and the hydrophobic layer 11 are alternately arranged along the axial direction of the heat exchange channel 1, the hydrophilic layer 10 promotes the uniform spreading of the heat exchange liquid, increases the heat exchange surface area, and improves the heat exchange efficiency; the hydrophobic layer 11 reduces the flow resistance, reduces the adhesion of the heat exchange liquid, reduces the pressure loss, improves the flow rate, and the alternating arrangement of the hydrophilic layer 10 and the hydrophobic layer 11 makes the heat exchange liquid form microcirculation locally, promotes fluid disturbance, increases turbulence, and enhances heat exchange; when the hydrophilic layer 10 and the hydrophobic layer 11 are alternately arranged along the ring direction of the heat exchange channel 1, the hydrophilic layer 10 makes the heat exchange liquid uniformly cover, improves the local heat exchange efficiency, the hydrophobic layer 11 reduces the viscous effect, reduces the flow resistance, improves the flow rate of the heat exchange liquid, and the heat exchange liquid forms stratified flow, which helps to reduce the dead zone and improve the uniformity of heat exchange. The hydrophilic layer 10 can be an oxidized metal coating or a nano-hydrophilic coating such as graphene; the hydrophobic layer 11 can be a PTFE coating, i.e. a fluorinated polymer coating such as polytetrafluoroethylene coating, or a silane coating.
