Embodiment Construction
[0013] Such as figure 1 , figure 2 As shown, the present invention includes a casing 1. The two ends of the casing 1 are equipped with tube plates. The inner wall of the casing 1 between the tube plates is provided with baffles arranged alternately, and the baffles are perpendicular to the length of the casing 1. , A number of heat exchange tubes 2 pass through the baffle, and are fixed on the tube plates at both ends in a square corner arrangement. The baffle includes an upper baffle 31, a lower baffle 32, an upper baffle 31, and a lower baffle. The baffle plates 32 are staggeredly arranged in the housing 1. One end of the upper baffle plate 31 is fixed to the upper wall in the housing 1, and the other end of the upper baffle plate 31 forms a circulation space with the inner and lower wall of the housing 1. One end of the plate 32 is fixed to the lower wall in the housing 1, and the other end of the lower baffle 32 forms a circulation room with the upper inner wall of the hou...

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 equipment, in particular to a double groove type enhanced tube heat exchanger. Background technique [0002] In various industrial production processes, the degree of heat utilization is directly related to the cost of the product and the benefit of the enterprise. Among them, the heat exchanger is the main equipment to recover waste heat or waste heat and improve the utilization rate of heat energy. It is currently widely used in oil refining and chemical production. This kind of commonly used equipment can transfer heat through this equipment to meet the needs of chemical processes. The heat transfer tube is the core element in the heat exchanger. Its structure not only affects the heat transfer coefficient of the tube side, but also affects the shell side. The existing longitudinal flow heat exchanger adopts a smooth round tube, which has low heat transfer efficiency, high energy consumption and un...
