Solar photovoltaic panel cooling device based on phase-change material

Technical Field

The utility model belongs to the technical field of cooling device, especially, relate to a solar photovoltaic board heat sink based on phase change material.

Background

The research and development quantity of solar photovoltaic panel cooling devices in the current market is small. The idea of the existing device is to stick a phase-change material cooling plate on the back plate of the solar photovoltaic panel, and the purpose of cooling the solar photovoltaic panel is achieved by absorbing heat through the phase-change material. The method is convenient and simple, low in material cost and easy to find, and has low requirements on installation operation technology and time, but the comprehensive effect is not good. The effect is unstable: because the solar power generation device is arranged in an open place outdoors, the solar power generation device is greatly influenced by weather environment, the pasting effect is greatly influenced by weather influences such as wind, water and the like, and unnecessary losses such as infirm pasting, uncontrolled pasting time and the like are easily caused; secondly, the cooling plate can not be detached: the problem that the cooling plate or the photovoltaic plate is difficult to repair can be caused by the fact that the cooling plate cannot be detached or is difficult to detach. In addition, in northern areas, the temperature is extremely low in winter, the phase-change material cooling plate is difficult to freeze, and once the solar photovoltaic panel is poor in effect under the low-temperature condition or the frozen cooling plate has adverse effects on the solar photovoltaic panel, the result is irreparable.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solar photovoltaic board heat sink based on phase change material, aim at promotes its generating efficiency through the operating temperature who reduces the solar photovoltaic board, and the dismantlement of the solar photovoltaic board of being convenient for simultaneously has avoided the cooling board because of the harmful effects that low temperature freezes to the photovoltaic board production.

In order to achieve the above object, the utility model adopts the following technical scheme:

a solar photovoltaic panel cooling device based on phase change materials comprises a main body frame matched with a solar photovoltaic panel and a cooling panel made of phase change materials, wherein slide rails are arranged on the inner sides of four corners of the main body frame, and a first bolt hole and a second bolt hole are formed beside each slide rail;

the solar photovoltaic panel and the cooling plate are both embedded into the main body frame, the cooling plate is located below the solar photovoltaic panel, the first bolt holes are used for fixing the solar photovoltaic panel, and the second bolt holes are used for fixing the cooling plate.

Further, the main body frame is a rectangular frame.

Furthermore, the main frame is four L-shaped structural bodies and is positioned at four corners of the solar photovoltaic panel.

Further, the main body frame is a metal frame.

Further, the slide rail is 4 or 8.

Compared with the prior art, the utility model discloses following technological effect has:

the utility model discloses a fix solar photovoltaic board and cooling board in main body frame, the cooling board is located the below of solar photovoltaic board, and the cooling board is made by phase change material, utilizes the heat retaining characteristics of phase change material to adsorb the heat of solar photovoltaic board, and the operation of cooling down is carried out automatically when solar photovoltaic board operating temperature reaches the predetermined temperature, makes the solar photovoltaic board maintain at the best temperature of work efficiency, does not consume other resources and acts on the year limit for a long time. Meanwhile, when the local area is in the north or is in a low-temperature condition, the design of the slide rail enables the solar photovoltaic panel and the cooling panel to be separated more conveniently, the negative influence of the low-temperature freezing cooling panel on the solar power generation panel is avoided, the failure rate of the solar photovoltaic panel caused by external conditions is reduced, the working efficiency and the use progress of the solar photovoltaic panel are effectively improved, the excellent industrial utilization potential is realized, and the problem that the traditional pasting method is not easy to separate is solved. The main frame type structure is adopted, so that the condition that the working efficiency is reduced due to dust deposition of a gap between the contact surfaces of the cooling plate and the photoelectric plate is effectively prevented.
