Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower cooling equipment, in particular to an antifreeze device for a cooling tower cooling coil. Background Art

[0002] With the continuous development of industrial production, cooling towers, as important cooling equipment, have been widely used in various fields. However, in winter or low temperature environments, the water in the cooling coils of cooling towers is prone to freezing, causing pipe ruptures and equipment damage, seriously affecting production safety. Therefore, designing an antifreeze device for the cooling coils of cooling towers is of great significance to ensure the normal operation of cooling towers.

[0003] The patent application number is 201821425280.0, which discloses an antifreeze device for a cooling tower cooling coil, including an air supply device and an electric heating device. The air supply device includes a fan and an air supply duct. The electric heating device consists of a shell, an end cover, an electric heater, a heating tube and an adjustable voltage power supply. The left end of the shell is open, and the right end of the shell is provided with an air inlet channel connected to the interior of the shell. The left end of the end cover is provided with an air outlet channel connected to the interior of the shell. The end cover is detachably mounted on the left end of the shell. The electric heater is arranged on the outer wall of the end cover, and the heating tube is installed on the inner wall of the end cover.

[0004] The antifreeze device of the cooling coil of the cooling tower dries the cooling coil at high temperature so that the cooling coil is in a dry state when not in use, and will not ice or freeze in a low temperature environment, thereby effectively protecting the cooling coil. However, there are still areas that can be improved. For example, when the hot air of the device passes through the cooling coil, the heat is constantly dissipated. It takes a long time to completely dry the entire cooling coil, and the heat loss is large, resulting in low heating efficiency and high economic consumption, which cannot meet current needs.
