Abstract
The invention discloses a hot-water exchanger, relating to a hot-water exchanger which exchanges heat by closed circulation of a water heater and external circulation of a client. The hot-water exchanger consists of a case, a combustion chamber arranged in the case, a combustor, a flue and a heat exchanging device arranged in the case; the flue is arranged on the side wall at one side of the case, the combustion chamber is provided with an erect clapboard, the lower part of the clapboard is provided with a plurality of through holes or through slots, the combustor is communicated with one chamber, the other chamber is communicated with the flue, and the heat exchanger is arranged between the other chamber and the flue; the water heater is connected with a heat exchanger, the water outlet of the water heater is connected with the internal circulation inlet of the heat exchanger, the water inlet of the water heater is connected with the internal circulation outlet of the heat exchanger, and the external circulation inlet and outlet of the heat exchanger is connected with an external circulation pipeline. In the invention, the structure that the former flue is arranged at the top of the case is changed, and the flue is arranged at the side of the case, thereby increasing the area for exchanging heat with the heat exchanger and further improving efficiency; and a dodge gate is arranged at the bottom of the flue, thereby being convenient for charging contamination and impurities.
Description
Technical field
The present invention relates to boiler technology, relate in particular to the hot-water exchanger that closing of a kind of hot water machine circulated and heat exchange is carried out in the outer circulation of user side.
Background technology
Domestic present employed atmospheric hot-water boiler is the vertical fire-tube type water heater for being made up of burner, combustion chamber, smoke pipe, boiler body, automatic water-supply and auto temperature controlled system mostly.Other country of the DIN board boiler and the world designs steam boiler and the hot-water boiler made and is horizontal fire tube boiler.Above-mentioned two kinds of designs are positive displacement, and promptly heated medium remains static in container, and heat transmission is that heated medium thermal conductivity factor under static state determines, thereby heat transfer rate is slow, and efficient is low.U.S.'s Cray is stepped on steam generator and has been changed above-mentioned design; It turns to a metal tube in the multilayer involute coil pipe that is serially connected; Flame after the fuel combustion and hot flue gas move outside metal tube; Heated medium flows in pipe, heated medium is absorbed heat at the volley, and enlarged heating surface area.But its weak point is that flame and the smoke movement distance after the burning is too short, at residing time in furnace very little, makes the heat energy after the conversion can not get fully absorbing, and the flue-gas temperature of discharging in the chimney is up to 350 ℃, and its heat energy utilization rate is low, and energy resource consumption is big.
Summary of the invention
The purpose of this invention is to provide a kind of sufficient combustion, heat exchanger effectiveness is high, and the hot-water exchanger of compact conformation.
Technical scheme of the present invention is: be made up of the combustion chamber of establishing in cabinet, the cabinet, burner, flue, the heat-exchange device that is arranged in the cabinet; Described flue is located on the sidewall of cabinet one side; Establish a upright dividing plate in the described combustion chamber, the lower partition is provided with some through holes or groove, and burner is communicated with one of them chamber; Another chamber is communicated with flue, and heat-exchange device is located between another chamber and the flue; Be connected with heat exchanger with hot water machine, the delivery port of hot water machine connects loop head in the heat exchanger, and the water inlet of hot water machine connects loop exit in the heat exchanger, and the outer circulation import and export of heat exchanger connects external circulation line.
Described heat exchanger is a plate type heat exchanger.
Flue of the present invention has changed the structure that in the past is arranged on the case top, is arranged on the case side, and this has increased the area that carries out heat exchange with interchanger, has further improved efficient; Owing in the flue carbon distribution, impurity are often arranged, the present invention is provided with dodge gate in the flue bottom, can make things convenient for the blowdown impurities removal, further improves the thermal efficiency; Pipeline between hot water machine and the plate type heat exchanger is short, and heat loss is little, can reach maximum temperature very soon during work, is in operation down at full capacity, has given full play to the thermal efficiency of " unit ".
Heating system absorbs the heat that " unit " sends through plate type heat exchanger, when the thermic load of heating system reduces, supplies water when reducing, and does not influence the operate as normal of " unit ", and the streamflow regime in the unit is a turbulent condition, can keep high heat transfer coefficient.After isolating with board-like parallel operation between heating system and " unit ", separately system can be independent of each other when heating system breaks down maintenance.Thereby the thermal efficiency that has guaranteed the hot water unit that we provided really reaches more than 90%.

The specific embodiment
Flue is located on the sidewall of hot water machine 1 cabinet one side, establishes a upright dividing plate in the combustion chamber, and the lower partition is provided with some through holes or groove, and burner is communicated with one of them chamber, and another chamber is communicated with flue, and heat-exchange device is located between another chamber and the flue; Be connected with heat exchanger 4 with hot water machine, the delivery port of hot water machine 2 connects loop head in the heat exchangers, and the water inlet 3 of hot water machine connects loop exit in the heat exchangers, and the outer circulation of heat exchanger is advanced, heat exchanger water inlet 5, heat exchanger delivery port 6 connect external circulation lines.Heat exchanger 4 is a plate type heat exchanger.
Claims (2)
1. hot-water exchanger is made up of the combustion chamber of establishing in cabinet, the cabinet, burner, flue, the heat-exchange device that is arranged in the cabinet, it is characterized in that; Described flue is located on the sidewall of cabinet one side; Establish a upright dividing plate in the described combustion chamber, the lower partition is provided with some through holes or groove, and burner is communicated with one of them chamber; Another chamber is communicated with flue, and heat-exchange device is located between another chamber and the flue; Be connected with heat exchanger with hot water machine, the delivery port of hot water machine connects loop head in the heat exchanger, and the water inlet of hot water machine connects loop exit in the heat exchanger, and the outer circulation import and export of heat exchanger connects external circulation line.
