Abstract

The utility model relates to a multi-segment volume-type heat exchanger, which comprises a casing, an air inlet, an air outlet and a heat exchanging room, wherein the bottom of the heat exchanging room is formed by heating surfaces, a siphon tube is arranged in the heat exchanging room, the top end of the heat exchanging room is provided with a flue gas discharge channel, the heat exchanging room is divided into a plurality of segments, and siphon tubes in the multiple segments of heat exchanging rooms are distributed in a crossing way, and the siphon tubes in each segment of heat exchanging rooms are distributed in a crossing way. The multi-segment volume-type heat exchanger utilizes smoke gas hot pipes which are arranged in a crossing way and a ring-shaped channel on the upper segment of the heat exchanger to reversely burn for many times, which prolongs heat exchanging time, leads heat of smoke gas to be forcedly absorbed by an indoor air medium layer, has sufficient heat exchanging and high heat utilization ratio, and saves production cost.

Description

Multisection displacement type heat exchanger

Technical field

The utility model relates to a kind of heat exchanger, is specifically related to a kind of multisection displacement type heat exchanger.

Background technology

The application of heat exchanger is very extensive, the cooling of automobile, industrial equipment or heat, heat exchange domestic hot water device, heating heat-exchange, heat radiation etc., particularly northern most of Weather Of Area is essential when cold, for example: resident's heating, the heating of manufacturer, retail shop and classroom and dormitory, and breeding, the chamber heating of plantation booth or the like.Present heat exchanger is of a great variety, utilizes heat energy such as electric energy, natural gas, and liquefied gas, coal gas, biogas, straw, solar energy, underground cold energy and coal or the like carry out heat exchange heating with aqueous medium or air dielectric.

Present stage, the most common high temperature heat aqueous medium heat exchanger also has volume of boiler type heat exchanger except pipe group plate heat exchanger, it mainly is made of the pipe group that is interspersed, many fins are set around the pipe group, the flowing velocity of these fins meeting limit air in the process of heat exchange, prolong the running time of air in heat exchanger, reach the purpose of sufficient heat exchange.But the shape of the fin that is provided with around this pipe group plate heat exchanger is straight chip, the effect of the fin limit air flow speed of this shape is also not obvious, air is also shorter the running time in heat exchanger, can not realize sufficient heat exchange, and, waste a large amount of heat energy with aqueous medium as the exchange media of heat energy, caused great energy waste.These traditional heat exchangers heat exchange efficiencies are all lower, generally all about 80～85%.

Summary of the invention

The purpose of this utility model is to provide a kind of multisection displacement type heat exchanger, and it has solved, and heat exchange is insufficient in the background technology, heat exchange efficiency is lower and the technical problem of energy waste.

Technical solution of the present utility model is:

A kind of multisection displacement type heat exchanger comprises housing 1, air inlet 2, gas outlet 3 and Heat Room 4, and the bottom of described Heat Room 4 is made of heating surface 6, is provided with siphon pipe 5 in the described Heat Room 4, and described Heat Room 4 tops are provided with waste gas passing away 8,

Its special character is: described Heat Room 4 is divided into multistage, is interspersed between the siphon pipe 5 in the multistage Heat Room 4; Be interspersed between the siphon pipe 5 in every section Heat Room 4.Be staggered flue gas heat pipe and heat exchanger epimere circular passage is repeatedly counter burns of utilization prolongs hot-fluid swap time, and the reverse compulsory room air medium of flue gas heat is absorbed layer by layer.

Be provided with cavity 7 between the above-mentioned multistage Heat Room 4, the end face of this cavity 7 and bottom surface constitute the heating surface 6 of buffering hot-fluid.Buffering heating, the slow burning prolong hot-fluid swap time and increase exchange area.

Above-mentioned described housing 1 comprises shell 11, inner casing 13 and is arranged at 12 between shell 11, the inner casing 13.Heat-insulation layer 12 is made of multilayer silicate composite heat-insulating coating and polyurethane integral foam layer.

The utility model modern design, simple in structure, heat exchange is abundant, and heat energy utilization rate height provides cost savings.
