Plane type heat exchanger

Abstract

The present invention relates to a plane type heat exchanger that has a simple structure and can be easily manufactured by substituting a rectangular plane type for a spiral cylindrical type of the structure of a heat exchange pipe according to the related art which is used for a heat exchanger using combustion gas that is heated by a burner and makes laminar flow. According to the present invention, the plane type heat exchanger having heat exchange pipes, through which heating water flows, and makes heat exchange by contacting with laminar-flow combustion gas, the plane type heat exchanger, includes: a plurality of heat exchange pipes that have a rectangular cross section with a larger width of a side, which contacts with the combustion gas, than the height, and are arranged at regular intervals in parallel with each other; inner plates where both ends of the heat exchange pipes are inserted to be fixed at regular intervals; and outer plates that are communicated with the heat exchange pipes through the inner plates and form spaces covering the outer surfaces of the inner plates.

Description

technical field [0001] The present invention relates to a planar heat exchanger, and more particularly, to a planar heat exchanger which has a simple structure and can be easily manufactured by using heat from a burner and generating a laminar flow ) of the gas heat exchanger, the spiral cylindrical structure of the heat exchange tubes of the prior art adopted in the heat exchanger is replaced with a rectangular planar structure. Background technique [0002] Generally, the heat exchanger used in a warm water heating boiler using fossil fuel is a pin-and-tube heat exchanger, which transfers the combustion heat of gas to the heat exchanger through heat transfer pins arranged around the surface of the heat exchange tube The fluid flowing inside the exchange tube. [0003] Devices for generating turbulent flow have been designed as pin-and-tube heat exchangers to improve heat exchange performance, and such devices are provided with heat transfer pins to increase heat exchange ...

AI Technical Summary

Problems solved by technology

[0011] However, the volume of the cylindrical heat exchanger in the prior art is large, and it should be made into a spiral shape and keep the space in the heat exchange tube 10 consistent, so its structural limitations are: it is difficult to manufacture, and Can only use cylindrical burners and not flat burners

[0012] In addition, when the cylindrical heat exchange tube 10 is fabricated in a spiral shape, the flat portion is deformed, making it difficult to flatten the surface.
