实验用的五种不同植物油的组成如表4所示，可以发现棉籽油和棕榈油的棕榈酸

The composition of the five different vegetable oils used in the experiment is shown in Table 4. It can be found that the palmitic acid, oleic acid and linoleic acid of cottonseed oil and palm oil are relatively high, the soybean oil has more linoleic acid, and the peanut oil has oleic acid and linoleic acid. The oleic acid content is relatively high, but the palmitic acid content of soybean oil and peanut oil is low, especially the content of several fatty acids in cottonseed oil is relatively balanced, which is the same as the thermal conductivity of cottonseed oil at room temperature in Table 3 is the largest, in Figure 11 different vegetable oils The temperature of cottonseed oil in the temperature peak during milling is also the lowest, indicating that the vegetable oil with high thermal conductivity has a strong cooling capacity;

The composition of the five different vegetable oils used in the experiment, as shown in Table 4, can be found that the palmic acid, oleic acid and linoleic acid of cottonseed oil and palm oil are relatively high, soybean oil has more linoleic acid, peanut oil oil and linoleic acid content is relatively high, but soybean oil and peanuts The palmic acid content of oil is low, especially the fatty acid content of cottonseed oil is relatively balanced, which is the largest consistency with the thermal conductivity of cottonseed oil at room temperature in Table 3, and the temperature of cottonseed oil is the lowest in the temperature peak of different vegetable oil milling in Figure 11. It is shown that the vegetable oil with high thermal conductivity has a strong cooling capacity.

The composition of five different vegetable oils used in the experiment is shown in Table 4. It can be found that the contents of palmitic acid, oleic acid and linoleic acid in cottonseed oil and palm oil are relatively high. The linoleic acid content of soybean oil is more than that of peanut oil. However, the content of palmitic acid in soybean oil and peanut oil is low, especially the content of several fatty acids in cottonseed oil is more balanced, which is consistent with cottonseed at room temperature in Table 3 In FIG. 11, the temperature of cottonseed oil is the lowest among the peak temperatures of different vegetable oils milling, which indicates that vegetable oils with high thermal conductivity have strong cooling capacity;<br>
