Rib type heat exchanger

Abstract

The invention relates to a rib type heat exchanger which is mainly used in a gas water heater, a water tank of an internal combustion engine, and an evaporator and a condenser of an air conditioner. The rib type heat exchanger comprises an inlet pipe and an outlet pipe, and is characterized by also comprising a long flat pipe, a heat exchange rib, an inner wall supporting rib, an inlet oblate transition joint and an outlet oblate transition joint, wherein the heat exchange rib and the inner wall supporting rib are directly formed by punching on the inner wall and outer wall of the long flat pipe; the inlet pipe and the outlet pipe are respectively connected with two ends of the long flat pipe; and the long flat pipe which is rolled into an elliptical or round columnar spiral body, the inlet pipe and the outlet pipe form an integral heat exchanger. By adopting the structure, the invention has the advantages that heat exchange is directly and simultaneously carried out by the heat exchange rib group and the pipe walls, the heat exchange mode is more direct and has a larger area, the concerned length of the pipes is longer, the efficiency is higher, the requirement for water pressure is lower, scale can not be generated on the inner walls, simultaneously, the processing technique is easier, and the cost is lower.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a ribbed heat exchanger. It is mainly used in heat exchangers of gas water heaters, condensers of air conditioners, evaporators of air conditioners, water tanks of internal combustion engines, etc., which can improve heat exchange efficiency and save energy. Background technique [0002] Traditional heat exchangers such as heat exchangers of gas water heaters, condensers of air conditioners, evaporators of air conditioners, and water tanks of internal combustion engines are heat-exchanged by heat-exchange fins, that is, the heat-exchange fins transfer the temperature to the tubes, and the tubes then transfer the heat to the tubes. The heat is transferred to the heat exchange medium in the tube; or conversely, the heat exchange medium transfers the temperature through the tube to the heat exchange fins, and then the heat exchange fins dissipate heat. This heat exchanger has the problem of very...

AI Technical Summary

Problems solved by technology

[0004]1. The heat exchange area of ​​the heat exchange medium (relative to the heating area and the volume of the heat exchange medium) is too small, resulting in very low heat exchange efficiency and wasting energy

[0005]2. The tube is heated by heat exchange fins, and the tube transfers heat to the heat exchange medium, or vice versa. The tube, the tube transfers heat to the heat exchange fins, and then the heat exchange fins dissipate heat. The heat resistance between the fins and the tube is large and the efficiency is low.

[0006]3. The fluid resistance of the tube is relatively small

[0008]5. The fins are thin and non-rigid, and the deformation of the fins during handling or cleaning will make the ventilation poor and reduce the efficiency
