Oil heating type laminating machine heating oil tank

Abstract

The invention relates to the technical field of photovoltaics, and discloses an oil heating type laminating machine heating oil tank, which comprises a heating oil tank. According to the oil heating type laminating machine heating oil tank, the heating oil tank is divided into a heating bin and a storage bin. Two rake tooth type crossed heat conduction oil pipe sets are arranged below the oil level in the heating bin. When the cooled heat conduction oil enters the heating bin of the heating oil tank, part of heat of the heated heat conduction oil can be absorbed through the heat conduction oilpipe; the temperature of the heat conduction oil after being absorbed can be reduced to the normal working temperature from the temperature higher than the working temperature of the laminating machine; the heat conduction oil is then extruded out of the heating bin by the entered low-temperature oil to enter the storage bin; and the low-temperature oil absorbing part of heat is preheated by thepart of heat before entering the heating bin, so that the subsequent heating duration is shortened, the efficiency is improved, the energy consumption is reduced, the temperature of the finally pumpedheat conduction oil is kept constant, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to an oil heating type laminator heating oil tank. Background technique [0002] The laminator is mainly used in the packaging process of solar cell modules. It presses materials such as EVA, solar cells, tempered glass and back film into a rigid whole under high temperature and vacuum conditions. The existing laminator There are two kinds of heating methods, one is circulating oil heating, and the other is electric heating. The traditional oil heating method is to insert the electric heating tube into the heating oil tank to reheat the cooled oil after circulation. Circulating heat conduction oil to realize heating of the laminator, but the existing traditional oil heating method always has the following problems: [0003] 1. The cooled oil inlet of the existing heating oil tank is directly connected to the oil tank, so that the cooled oil is mixed with the oil heated by the...

Problems solved by technology

[0003] 1. The cooled oil inlet of the existing heating oil tank is directly connected to the oil tank, so that the cooled oil is mixed with the oil heated by the electric heating tube in the oil tank, and the high temperature oil is used to neutralize the temperature of the low temperature oil , but this kind of mixing method will only produce a better mixing effect at the inlet of the oil pipe, but the oil temperature in other parts is still higher than the oil temperature required by the air compressor, and the mixing effect of high and low temperature oil is extremely poor. The oil temperature distribution is extremely uneven, but such uneven heat transfer oil is directly pumped to the air compressor to work, which will lead to extremely uneven working temperature of the pressure plate of the air compressor. If the temperature is too high, the temperature will be too high or If it is too low, it will have a great impact on the quality of the final product, resulting in that the product quality cannot be guaranteed to be consistent.

[0004] 2. The electric heating tubes in the existing heating oil tank are directly heated in contact with the heat transfer oil, and the heat transfer oil will dissolve air during the cooling cycle and when it is added to the oil tank, and the heat transfer oil will be oxidized during the heating process These products will adhere to the electric heating tube, which will reduce the heat conduction efficiency of the electric heating tube after a long time. At the same time, due to the helical structure of the electric heating tube, these adhered products are also extremely difficult to clean. Trouble, in severe cases, the electric heating tube will be burned, causing potential safety hazards
