Cooler capable of preventing row tubes from being fractured and based on energy conservation law

Abstract

The invention discloses a cooler capable of preventing row tubes from being fractured and based on an energy conservation law. The cooler structurally comprises a water collecting groove plate, a control panel, a cooler body and a gas pretreatment device; and the left side of the gas pretreatment device is connected to the upper end of the right side of the interior of the cooler body in a nestedmode. According to the cooler capable of preventing the row tubes from being fractured and based on the energy conservation law, the cooler has the effect of being capable of releasing high-temperature energy in the gas extruding process when cooling gas with the large workshop temperature difference through cooperation of a dynamic vortex disk and a static vortex disk, then the gas is subjected to turbulence treatment through a spring, a lower end plate and an upper end plate, thus the flowing speed of the gas is decreased, and gas molecular motion is weakened; and according to the energy conservation law, internal energy of the gas is reduced, mechanical energy of the gas is increased, thus the high-temperature gas is pre-cooled, the high-temperature gas is effectively prevented from making contact with a heat exchange tube directly, and thus the row tubes in the cooler are prevented from being fractured.

Description

technical field [0001] The invention is a tube rupture prevention cooler based on the law of energy conservation, which belongs to the field of air conditioning and refrigeration. Background technique [0002] The cooler is a type of air-conditioning heat exchange equipment used to cool the fluid, usually using water or air as the coolant to remove heat, and the cooler is generally divided into a vertical tube cooler and a horizontal tube cooler. In hot processing workshops, horizontal tube coolers are often used to replace and cool the gas. [0003] However, the horizontal tube coolers on the market use expansion and welding between the condensing tubes and the tube sheet. In the processing workshop, the inlet gas temperature can be as high as 50 or 60 degrees Celsius, and the cooling water temperature inside the cooler is at Below 30 degrees Celsius, the temperature difference is large, and because the thermal expansion coefficient of the heat exchange tube and the shell ...

[0003] However, the horizontal tube coolers on the market use expansion and welding between the condensing tubes and the tube sheet. In the processing workshop, the inlet gas temperature can be as high as 50 or 60 degrees Celsius, and the cooling water temperature inside the cooler is at Below 30 degrees Celsius, the temperature difference is large, and because the thermal expansion coefficient of the heat exchange tube and the shell is different, coupled with the large temperature difference stress, it is easy to drive the heat exchange tube to become thinner, and the thinned place will crack after a long time, resulting in the tube Leakage is prone to occur, causing nitrogen in the air to enter the circulating water in the cooler to produce dilute nitric acid, which will corrode the carbon steel shell and composite tube sheet, thereby accelerating the rupture of the tubes
