Embodiment Construction
[0027] Such as Figure 1-3 As shown, the shell-and-tube heat exchanger with special-shaped channel without baffles according to the embodiment of the present invention includes a cylinder body 1 and a heat exchange tube 2. The cylinder body 1 is a hollow structure penetrating in the axial direction, and the entire space in the cylinder body 1 is There is no baffle to block the flow area 4, so that the medium in the cylinder 1 has no baffles and detours when flowing, and realizes the uniform flow of the medium in the cylinder 1 outside the heat exchange tube 2, eliminating the traditional stagnation zone 5.
[0028] A number of evenly distributed heat exchange tubes 2 are arranged in the cylinder body 1, so that the medium outside the heat exchange tubes 2 can completely realize the flow along the special-shaped channel in the axial direction, which strengthens the disturbance and turbulence, and facilitates the realization of countercurrent or downstream flow. Better heat con...

The invention relates to a shell and tube heat exchanger with a special shaped channel but without a baffle plate, substantially comprising a cylindrical shell and a heat exchange pipe inside the cylindrical shell, the cylindrical shell is a hollow structure which runs along the axial direction, the whole space inside the cylindrical shell is a flow area which is not blocked by the baffle plate; a plurality of evenly distributed heat exchange pipes are arranged in the cylindrical shell, the heat exchange pipes exist in the inner wall of the cylindrical shell in varying forms; a medium inside the cylindrical shell evenly flows along the axial direction; the media inside and outside the heat exchange pipes flow downstream or upstream. The invention has the effects of novel structure design, simple structure, convenient manufacturing, thus reducing costs in manufacturing, maintenance and use; the design of the structure without the baffle plate changes the flow direction of media inside and outside the heat exchange pipes, strengthens perturbation, intensifies turbulent current, completely realizes direct flow and counter flow, improves thermal transmission efficiency, strengthens heat exchange effect and improves product performance, thus meeting development demands of the market and contributing to popularization of the product.
Description
technical field [0001] The invention relates to a shell-and-tube heat exchanger, in particular to a shell-and-tube heat exchanger with special-shaped channels without baffles, which can be widely used in electric power, petroleum, chemical industry, environmental protection, pharmacy, air-conditioning and other fields. Background technique [0002] Taking shell-and-tube heat exchangers mainly used in air-conditioning dry evaporators as an example, the current shell-and-tube heat exchangers for air-conditioning are divided into different types of heat exchangers according to their structure: different heat exchanger tube fins, different number of processes, straight tube , U-shaped tubes, etc., the baffles have upper and lower openings, left and right openings, spiral openings, and different forms of uniform distributors. Although the performance of shell-and-tube heat exchangers of these structures has been improved to varying degrees through some improvements, there are sti...
