Abstract
The utility model discloses a high-efficiency energy-saving heat exchanger, which is arranged above a combustion apparatus. The high-efficiency energy-saving heat exchanger is in a mutually circuitous parallel structure which can be provided with two row of mutually circuitous parallel water tubes which are arranged in parallel; a baffle plate which can make flue gas generated from the combustion apparatus flow circuitously and in parallel in the horizontal direction is arranged between every two water tubes which are arranged in parallel; a plurality of heat conducting fins can be arranged on the water tubes; the mutually circuitous parallel structure can be a mutually circuitous structure arranged in parallel. The high-efficiency energy-saving heat exchanger can effectively reduce the temperature of the flue gas and increase the heat efficiency.
Description
Technical field
The utility model relates to a kind of heat exchanger, particularly relates to a kind of high-efficiency and energy-saving heat exchanger.
Background technology
At present, generally the gas heat exchanger of Shi Yonging is arranged at the top of burner for water pipe being attached to vertical surrounding on the metallic plate, and useful up conducting strip connects the heat exchanger of the circuitous water pipe of parcel.Because the thermal source that burner sends is few with heat exchange area, particularly the centre that firepower is the strongest is few with the area of heat exchanger contact, and time of contact is short, and fully heat exchange causes the exhaust outlet temperature very high, and the thermal efficiency is low.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of high-efficiency and energy-saving heat exchanger, can reduce the smoke discharging temperature effectively, improves the thermal efficiency.
For solving the problems of the technologies described above, the utility model provides a kind of high-efficiency and energy-saving heat exchanger, is arranged on the top of burner, and this heat exchanger is mutually circuitous parallel structure.
Described mutually circuitous parallel construction is the mutually circuitous parallel water pipe that two rows are set up in parallel, and is provided with between every pair of water pipe that is set up in parallel and can makes flue gas that described burner the produces plate washer of circuitous PARALLEL FLOW in the horizontal direction.
Described water pipe is provided with some conducting strips.
Perhaps, the screen shape structure of described mutually circuitous parallel construction for making a circulation mutually to be arranged in parallel.
Described torch fuel is fuel gas or fuel oil.
In the embodiment of the present utility model, described heat exchanger is provided with the mutually circuitous parallel water pipe that two rows are set up in parallel, and between every pair of water pipe that is set up in parallel, be provided with plate washer, the PARALLEL FLOW so that the flue gas that described burner produces can make a circulation in the horizontal direction, be that flue is parallel with flue, this circuitous parallel construction of this heat exchanger helps the heat-exchange time of prolong smoke at the gas flue, increased the heat exchange area of flue gas and water greatly, effectively reduce the smoke discharging temperature, improved the thermal efficiency.Preferably, on described water pipe, be provided with some conducting strips, help the heat absorption of water pipe.
In another embodiment of the present utility model, the screen shape structure of described heat exchanger for making a circulation mutually to be arranged in parallel, this screen shape structure makes between flue and the flue, be parallel to each other between water channel and the water channel, equally, help the heat-exchange time of prolong smoke, increased the heat exchange area of flue gas and water, improved the thermal efficiency at the gas flue.
The high-efficiency and energy-saving heat exchanger that the utility model provides can reduce the smoke discharging temperature effectively, improves the thermal efficiency.
