The air-to-water cooler is mainly used in various equipments that use a mixture of water, a mixture of refrigerant and water as a heat medium, and the purpose of cooling the high-temperature water passing through the heat exchanger is achieved by air-cooling.
Applications: Construction machinery engine, air compressor, industrial spraying equipment, new energy equipment, solar equipment, power equipment, marine equipment, wind power equipment, sewage treatment system, etc.

First, the proportion of low-yielding rubber farms is too high. At present, China's rubber park has less than 50 kilograms of old rubber yard per mu, and there are 1.95 million mu of land, and nearly 3 million mu of new rubber fields have not yet been cut. The privately-owned rubber garden has a low level of science and technology, the aging of varieties, and the tapping process is behind, and the potential for production has not been fully realized.
Second, the layout of natural rubber planting areas is irrational, and planting varieties are aging only. Although China had already introduced Brazil rubber trees as early as 1904, large-scale planting was after the founding of New China. In the rubber tree planting process, due to the lack of understanding of rubber tree growth, rubber production conditions, and planting environment at the beginning of the rubber plantation, rubber trees were frequently planted in the eastern part of Hainan where typhoons struck frequently, resulting in the unreasonable planting of rubber bases in Hainan and the uniqueness of rubber trees. Aging, slow promotion of good new varieties, and high grade standard rubber rely on imports for a long time, which is also a prominent contradiction between the structure of natural rubber products in China and market demand.
Third, the overall efficiency of the natural rubber industry is not high. The main products of the natural rubber industry are rubber and wood, and the by-products are seed oil. At present, the parties do not pay enough attention to the growth and accumulation of rubber trees. In Malaysia, 70%-80% of the wood used in the furniture industry is rubber wood. Malaysia exports about 2 billion US dollars worth of rubber wood furniture each year.
Fourth, rubber processing plants are small in scale and their product development capabilities are not strong. The rubber farming enterprises in China, regardless of the planting area of ​​rubber, have built their own rubber processing plants, with an annual output of more than 500,000 tons of dry glue, processed and produced by 324 processing plants. The average annual production capacity of processing plants is only 1,600 tons. . The processing capacity of rubber processing plants in the main producing countries of natural rubber in Southeast Asia is generally more than 10,000 tons. The small scale of the rubber processing plant causes high processing costs and poor product performance, and it is difficult for new technologies to be popularized.
Advantages: Strong corrosion resistance, compact structure, small footprint, and high degree of customization.various air-cooled drive modes, DC motor, AC motor, hydraulic motor, air motor, special explosion-proof motor, etc., better to choose the appropriate drive mode according to industrial environmental factors, without the help of external cooling medium, lower The hardware requirements can be used to cool the oil and ultimately ensure the benign operation of the equipment.
There are four major problems in China's natural rubber industry that restrict the rapid development of the industry.
