Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic energy storage, and in particular relates to a photovoltaic energy storage heat dissipation device. Background Art

[0002] In the context of the current global energy structure transformation, photovoltaic power generation, as a clean and renewable energy form, has received widespread attention and application. Energy storage refers to the process of storing energy through a medium or device and releasing it when needed. The energy storage device of a photovoltaic power station will emit a lot of heat when working.

[0003] The Chinese utility model patent currently announced as CN218217292U discloses a heat dissipation device for a photovoltaic power station energy storage device, which is provided with a heat dissipation frame. An accelerated discharge movement mechanism is provided in the middle of both sides of the inner cavity of the heat dissipation frame. An electric fan is movably installed in the middle of the upper end of the inner cavity of the heat dissipation frame. A temperature controller is movably installed on the right side of the middle of the upper end of the heat dissipation frame. The above-mentioned arrangement can prevent the energy storage mechanism from malfunctioning and the failure to timely discover problems that may cause malfunctions or even safety accidents.

[0004] This patent only uses an electric fan to inject cold air from the outside into the energy storage box, and takes away the external heat through the gas flow. However, the energy storage box is composed of several battery packs, and the contact surfaces of the several battery packs are not easily affected by the gas flow, resulting in poor heat dissipation efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a photovoltaic energy storage heat dissipation device, which solves the problem of an existing heat dissipation device of a photovoltaic power station energy storage device, which only injects external cold air into the energy storage box through an electric fan and takes away the external heat through gas flow. However, the energy storage box is composed of a plurality of battery packs, and the contact surfaces of the plurality of battery packs are not easily affected by the gas flow, resulting in poor heat dissipation efficiency.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a photovoltaic energy storage and heat dissipation device, comprising an energy storage box, wherein a plurality of energy storage battery packs are arranged evenly inside the energy storage box, and a water cooling mechanism is provided between the plurality of energy storage battery packs;

[0007] The water cooling mechanism includes a heat transfer plate, a serpentine cooling pipe, a water inlet pipe, a water outlet pipe, an output pipe, a recovery pipe, a water pump and a water tank. There are several heat transfer plates, and several of the heat transfer plates are fixedly arranged between several energy storage battery packs. The shrink heat transfer plate is hollow. The serpentine cooling pipe is arranged inside the heat transfer plate, the water inlet pipe is fixedly arranged at one end of the serpentine cooling pipe, the water outlet pipe is fixedly arranged at the other end of the serpentine cooling pipe, the output pipe is arranged at one end of the water inlet pipe, the recovery pipe is arranged at one end of the water outlet pipe, the water pump is arranged on the output pipe, and the water tank is fixedly arranged on a side wall of the energy storage tank. The output pipe and the recovery pipe both extend to the interior of the water tank.

[0008] The above technical solution is adopted, by setting an energy storage box, an energy storage battery pack and a water cooling mechanism. When in use, the energy storage box can first be installed and fixed to the energy storage battery pack. When the temperature inside the energy storage box is too high, the water cooling mechanism is turned on to cool the energy storage battery pack through the water cooling mechanism, wherein the water cooling mechanism includes a heat transfer plate, a serpentine cooling pipe, a water inlet pipe, a water outlet pipe, an output pipe, a recovery pipe, a water pump and a water tank. When in use, first add coolant to the water tank, and then fix several heat transfer plates between several energy storage battery packs. The heat transfer plates are hollow and can install and fix the serpentine cooling pipe. When the temperature of the energy storage battery pack is too high, the water pump is turned on to release the coolant in the water tank through the output pipe and the inlet pipe. The water pipe is injected into the serpentine cooling tube, and then the heat transfer plate transfers the heat in the energy storage battery pack to the inside of the heat transfer plate, and then exchanges heat with the coolant in the serpentine cooling tube, which can dissipate heat for the energy storage box. The serpentine cooling tube is arranged in a serpentine shape, which can increase the time the coolant flows in the serpentine cooling tube, thereby increasing the time of heat exchange of the coolant, thereby improving the heat dissipation efficiency. Since the heat transfer plate is arranged between the energy storage battery packs, it can avoid the poor heat dissipation effect of the contact surface of the energy storage battery pack. After the coolant flows through the serpentine cooling tube, the coolant continues to be injected, and the new coolant squeezes the coolant after heat exchange into the water tank through the outlet pipe and the recovery pipe, achieving the effect of reuse.

[0009] Furthermore: a sealing cover is provided at the upper end of the energy storage box, the sealing cover is fixedly connected to the energy storage box by bolts, a cooling fan is provided at the upper end of the sealing cover, and the output end of the cooling fan extends to the interior of the sealing cover.

[0010] By adopting the above technical solution, a sealing cover and a cooling fan are provided. When in use, the sealing cover can seal the energy storage box to prevent external impurities from entering the energy storage box, and then the cooling fan can inject cold air into the energy storage box to dissipate heat from the energy storage box.

[0011] Furthermore: a temperature sensor is provided on the inner wall of the energy storage box, and a controller is provided on the outer wall of the energy storage box, and the controller is electrically connected to the temperature sensor.

[0012] By adopting the above technical solution, by setting a temperature sensor and a controller, when in use, the temperature sensor can monitor the temperature inside the energy storage box. When the temperature inside the energy storage box is low, heat is dissipated only by the cooling fan. When the temperature inside the energy storage box is too high, the energy storage box is cooled by the coolant, and then the controller can display the temperature inside the energy storage box.

[0013] Furthermore: a through opening is provided on the side wall of the energy storage box, a mounting plate is fixedly provided inside the through opening, and heat dissipation holes are provided on the mounting plate, and the heat dissipation holes are multiple and evenly arranged.

[0014] By adopting the above technical solution, by providing a through-hole, a mounting plate and a heat dissipation hole, when in use, the through-hole can first provide an installation environment for the mounting plate, and then the heat dissipation hole is provided on the mounting plate. When the cooling fan injects cold air into the energy storage box, it can squeeze the hot air inside the energy storage box and discharge the hot air through the heat dissipation hole.

[0015] Furthermore: a hanging ring is fixed on the upper surface of the sealing cover, and the number of the hanging rings is two and they are symmetrically arranged.

[0016] By adopting the above technical solution and providing a lifting ring, the lifting ring can provide a fulcrum for fixing and removing the sealing cover during use, thereby facilitating the movement of the sealing cover.

[0017] Furthermore: a condenser is provided on the recovery pipe.

[0018] By adopting the above technical solution and setting up a condenser, the cooling effect of the coolant will be reduced after the coolant undergoes heat exchange. At this time, the coolant flowing through the condenser can further restore the cooling effect of the coolant.

[0019] Furthermore: the bottom of the energy storage box is fixedly connected with a support column, the number of the support columns is four and they are symmetrically arranged, and the lower surface of the support column is provided with an anti-slip pad.

[0020] By adopting the above technical solution, by setting support columns and anti-slip pads, when in use, the support columns can first support and fix the energy storage box, thereby increasing the ground clearance of the energy storage box, and then the anti-slip pads can increase the friction between the support columns and the ground, thereby further increasing the friction of the energy storage box.

[0021] Furthermore: a filter plate is detachably provided inside the sealing cover.

[0022] By adopting the above technical solution and setting a filter plate, when the cooling fan injects cold air into the energy storage box, the cold air will first pass through the filter plate, which can prevent impurities in the outside world from entering the interior of the energy storage box.

[0023] In summary, the present invention has the following beneficial effects:

[0024] By setting up a water cooling mechanism, first, coolant is added to the water tank, and then several heat transfer plates are fixed between several energy storage battery packs. The heat transfer plates are hollow and can be used to install and fix the serpentine cooling tubes. When the temperature of the energy storage battery pack is too high, the water pump is turned on to inject the coolant in the water tank into the serpentine cooling tubes through the output pipe and the water inlet pipe. The heat transfer plate then transfers the heat in the energy storage battery pack to the inside of the heat transfer plate, and then exchanges heat with the coolant in the serpentine cooling tubes, which can dissipate heat for the energy storage box. The serpentine cooling tubes are serpentine in shape, which can increase the time the coolant flows in the serpentine cooling tubes, thereby increasing the time the coolant heat exchanges, thereby improving the heat dissipation efficiency. Since the heat transfer plates are arranged between the energy storage battery packs, the poor heat dissipation effect of the contact surface of the energy storage battery pack can be avoided. After the coolant flows through the serpentine cooling tubes, coolant continues to be injected. The new coolant squeezes the coolant after heat exchange into the water tank through the outlet pipe and the recovery pipe, thereby achieving the effect of reuse.

[0025] By setting up a sealing cover and a cooling fan, when in use, the sealing cover can seal the energy storage box to prevent external impurities from entering the energy storage box, and then the cooling fan can inject cold air into the energy storage box to dissipate heat from the energy storage box.

[0026] Based on the above improvements, the overall technical effect achieved by this device is that the heat transfer plate can contact the two side walls of the energy storage battery pack, and then heat exchange is carried out through the coolant, avoiding the situation where the contact surface heat dissipation effect of some energy storage battery packs is not ideal.
