Technical Field

[0001] The utility model belongs to the technical field of photovoltaic energy storage inverters, and more specifically, relates to a heat dissipation bracket structure for a photovoltaic energy storage inverter. Background Art

[0002] When a photovoltaic energy storage inverter is operating, it generates heat and needs to be cooled in time to prevent the internal temperature from being too high, which may cause the electronic components to burn out. Generally, heat dissipation fins are provided on the side of its shell for heat dissipation to reduce the internal temperature, and its back is connected to a fixed bracket. However, the side area is small, and the back is connected to the fixed bracket, so the back cannot be used for heat dissipation. This results in poor heat dissipation efficiency and a relatively high surface temperature. Therefore, how to make full use of the back of the photovoltaic energy storage inverter for heat dissipation is a technical problem that those skilled in the art urgently need to solve. Summary of the Utility Model

The heat conduction sheet is laid flat on the back of the photovoltaic energy storage inverter shell, and a plurality of heat dissipation fins are connected to the back of the heat conduction sheet in parallel and at intervals; a groove is provided in the middle of the first purlin, and a plurality of through holes are provided through both sides. The edges of the heat dissipation fins are inserted into the groove, and the second bolt passes through the through hole and the edge of the heat dissipation fin.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] In addition, the technical features involved in the various implementation manners of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] The heat dissipation bracket for a photovoltaic energy storage inverter in the preferred embodiment of the present utility model is as shown in Figures 1 to 4 A heat dissipation bracket for a photovoltaic energy storage inverter includes a first purlin, a radiator, a first bolt, a second bolt and a photovoltaic energy storage inverter housing; the radiator includes a heat conducting sheet and a plurality of heat sink fins, the first bolt passes through the heat conducting sheet and is connected to the photovoltaic energy storage inverter housing, the heat conducting sheet is laid flat on the back of the photovoltaic energy storage inverter housing, and the plurality of heat sink fins are connected to the back of the heat conducting sheet in parallel and at intervals; a groove is provided in the middle of the first purlin, and a plurality of through holes are provided through both sides, the edges of the heat sink fins are inserted into the groove, and the second bolt passes through the through holes and the edges of the heat sink fins.

[0027] The heat dissipation bracket of the photovoltaic energy storage inverter of the present utility model is provided with a groove in the middle of the first purlin, and a number of through holes are provided through both sides. The edge of the heat sink is inserted into the groove, and the second bolt passes through the through hole and the edge of the heat sink. The first purlin is connected to the radiator, the radiator is connected to the back of the photovoltaic energy storage inverter housing, and the first purlin is connected to fixed objects such as walls. It can not only support the photovoltaic energy storage inverter, but also increase the heat dissipation area of the photovoltaic energy storage inverter. By connecting the heat conduction sheet to the back of the photovoltaic energy storage inverter, the back of the photovoltaic energy storage inverter is fully utilized for heat dissipation. The heat dissipation efficiency is improved. The connection structure of the first purlin and the radiator by the second bolt forms the main structure of the heat dissipation bracket. The present utility model is not limited thereto, and other structures that can connect the first purlin and the radiator are also applicable to the present utility model, such as welding, plugging, and clamping.

[0028] In order to install the photovoltaic energy storage inverter more flexibly and diversely, the present utility model is further configured such that a second purlin is connected to the back of the first purlin through a beam clamp, and the first purlin is perpendicular to the second purlin. The first purlin is connected to the wall through the second purlin, which improves the degree of freedom and enables more flexible and diverse connection to the wall. Different types of instruments and equipment can be mounted on the first purlin and the second purlin at the same time. It is more convenient to install and build. The beam clamps in the prior art are also applicable to the application of the present utility model.

[0029] The present utility model is further configured such that the second purlin is a C-shaped steel. C-shaped steel is widely used and is detachably connected together when used in combination with beam clamps and the first purlin.

[0030] Close to the natural air flow, the heat dissipation efficiency is low. In order to improve the heat dissipation efficiency, the present utility model is further configured such that a fan is provided between adjacent heat sinks. The fan operates to promote air flow, accelerate the removal of heat from the heat sink, prevent heat accumulation, effectively improve the heat dissipation efficiency, and reduce the temperature of the photovoltaic energy storage inverter.

[0031] In order to prevent the heat sink from crushing the fan, the present utility model is further configured such that an elastic foam is provided between the edge of the fan and the adjacent heat sink. Under the action of external force, the elastic foam is easily deformed and immediately returns to its original state after the external force is removed, which can well buffer the force of the heat sink on the fan. Prevent the heat sink from being deformed by thermal expansion and contraction and crushing the fan. Preferably, the air outlet of the fan is in the same longitudinal direction as the adjacent heat sink. An air flow channel is formed between adjacent heat sinks and flows from one end of the heat sink to the other end.

[0032] To prevent the fan from being deformed and melted due to the high temperature of the heat sink, the present utility model is further configured such that the fan is disposed at the bottom of the heat sink. As the air is conveyed by the fan, it flows from the bottom to the top of the heat sink. The heat sink transfers heat to the air, and the air temperature rises. The air temperature at the bottom of the heat sink is lower than that at the top. By disposing the fan at the bottom of the heat sink, the heat transferred from the air to the fan is also lower, avoiding the risk of high-temperature deformation and melting.

[0033] To improve the heat dissipation efficiency, the present utility model is further configured such that a heat-conducting paste is applied between the heat-conducting sheet and the back surface of the photovoltaic energy storage inverter housing. The heat-conducting paste eliminates the gap between the heat-conducting sheet and the back surface of the photovoltaic energy storage inverter housing. Heat is transferred sequentially through the back surface of the photovoltaic energy storage inverter housing, the heat-conducting paste, the heat-conducting sheet, the heat sink, and the air. The heat-conducting paste accelerates the transfer of heat to the heat-conducting sheet, improving the heat conduction coefficient and facilitating the improvement of the heat dissipation efficiency.

[0034] To improve the heat dissipation efficiency, the present utility model is further configured such that the heat-conducting sheet has the same shape as the back surface of the photovoltaic energy storage inverter housing, and the heat-conducting sheet overlaps the back surface of the photovoltaic energy storage inverter housing. Preferably, the heat-conducting sheet and the heat sink are made of aluminum alloy material, which not only has a fast heat conduction speed but also has high structural strength and can stably support the photovoltaic energy storage inverter.

[0035] It is easy for those skilled in the art to understand that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
