Double-slot type strengthened pipe type heat exchanger

Abstract

The invention provides a double-slot type strengthened pipe type heat exchanger. By the adoption of the double-slot type strengthened pipe type heat exchanger, heat transfer can be enhanced greatly, and energy consumption is saved, so that heat transfer efficiency is improved effectively, and the heat exchange effect is good. The double-slot type strengthened pipe type heat exchanger comprises a shell. Pipe plates are mounted at the two ends of the shell. Baffle plates alternately arranged are arranged on the position, between the pipe plates, of the inner wall of the shell. The baffle plates are perpendicular to the shell in the length direction. Heat exchange pipes penetrate the baffle plates and are fixed to the pipe plates at the two ends in a turning square arrangement manner. An inlet communicating with the shell and a feeding opening communicating with the heat exchange pipes are formed in the upper wall of the outer portion of the shell. An outlet communicating with the shell and a discharging opening communicating with the heat exchange pipes are formed in the lower wall of the outer portion of the shell. Cross grain slots and spiral slots are formed in the peripheral face of the outer wall of each heat exchange pipe in a rolling manner and alternately distributed in the outer wall of each heat exchange pipe. Fins are manufactured on the outer wall of each heat exchange pipe. A spiral spring and a wave strip are inserted into each heat exchange pipe and arranged in each heat exchange pipe in a crossed manner.

Description

technical field [0001] The invention relates to a liquid material heat exchange device, in particular to a double-slot reinforced tube heat exchanger. Background technique [0002] In various industrial production processes, the degree of utilization of heat energy is directly related to the cost of the product and the benefit of the enterprise. The heat exchanger is the main equipment for recovering waste heat or waste heat and improving the utilization rate of heat energy. It is a widely used in oil refining and chemical production. A commonly used equipment, through which heat transfer can be carried out to meet the needs of chemical technology, and the heat transfer tube is the core component of the heat exchanger, its structure not only affects the heat transfer coefficient of the tube side, but also affects the shell side The heat transfer coefficient is low. The existing longitudinal flow heat exchanger uses a smooth round tube, which has low heat transfer efficiency,...
