Abstract
The utility model relates to a heat exchanger for a gas water heater, which comprises a thick heat exchanging pipe and a thin heat exchanging pipe which is covered by the thick heat exchanging pipe, wherein, a water inlet and a water outlet of the thick heat exchanging pipe are connected with a loop of a heating hot water system; a water inlet of the thin heat exchanging pipe is connected with a cold water inlet pipe, and a water outlet of the thin heat exchanging pipe is connected with a bath hot water pipeline; the cold water input from the water inlet of the thick heat exchanging pipe or heating returning water is directly heated into high temperature hot water in the thick heat exchanging pipe to the heating system; in the process of high temperature hot water flowing in the thick heat exchanging pipe, the cold water in the pipe bundle of the bath thin heat exchanging indirectly heats the cold water to the low temperature hot water in the bath equipment. The utility model has the advantage of energy saving, and the inner wall of the utility model is not easy to form fur.
Description
The utility model belongs to gas heater accessory field, particularly relates to a kind of heat exchanger of gas heater.
Public gas heater heat exchanger is made up of a heat exchanger tube and the fin that is enclosed within on the heat exchanger tube, and an end of heat exchanger tube is a cold water inlet, and the other end is a hot water outlet, and this heat exchanger can only be exported a kind of hot water of temperature.
The purpose of this utility model provides a kind of heat exchanger, and it can export the hot water of two kinds of temperature simultaneously to two systems.
To achieve these goals, the utility model has adopted following scheme:
A kind of gas heater heat exchanger, comprise heat exchanger tube, be enclosed within the fin on the heat exchanger tube, water inlet and delivery port are arranged on the heat exchanger tube, it is characterized in that: every group of heat exchanger tube comprises a thick heat exchanger tube and by the thin heat exchanger tube of its containing, the water inlet of thick heat exchanger tube is connected with the loop of delivery port with the heating hot water pipe, the water inlet of thin heat exchanger tube stretches out from the end of thick heat exchanger tube and links to each other with cold water inlet, thin heat exchanger tube delivery port stretches out from the end of thick heat exchanger tube and is connected with the bath hot water pipeline, two water routes are arranged in the heat exchanger, and two water routes in thick heat exchanger tube and the thin heat exchanger tube are individual flow separately.
The quantity of described heat exchanger tube is two groups or more, and two groups of thick heat exchanger tubes put stator at both ends, connects with the extra heavy pipe bypass pipe in the end between the thick heat exchanger tube, and thin heat exchanger tube is tube bank, connects with thin bypass pipe between the tube bank.
Operation principle of the present utility model is: directly be heated to be high-temperature-hot-water from the cold water or the heating backwater of thick heat exchanger tube water inlet input in thick heat exchanger tube, lead to the heating hot water pipeline from the delivery port output of extra heavy pipe then.Cold water flows into thin heat exchanger tube tube bank from thin heat exchanger tube water inlet, high-temperature-hot-water in the thick heat exchanger tube is in flow process, tube wall by thin heat exchanger tube tube bank, with the cold water indirect in the thin heat exchanger tube, but temperature is lower than the hot water in the thick heat exchanger tube, and the hot water in the thin then heat exchanger tube tube bank flows out from thin heat exchanger tube outlet and leads to Bathing apparatus.
The utility model has the advantages that: same heat exchanger can be simultaneously to the hot water of two kinds of temperature of two system's output, and high-temperature-hot-water is imported the heating heat dissipation equipment, low-temperature water heating input bath apparatus, and heat-energy losses is little, energy savings.Flame directly heats thick heat exchanger tube, and thin heat exchanger tube is not directly by flame heat, and inwall is less scaling.
Below in conjunction with accompanying drawing the utility model is done further detailed description:
Fig. 1 is a structure scheme of installation of the present utility model;
Fig. 2 is the sleeve structure schematic diagram of thick heat exchanger tube of the present utility model and thin heat exchanger tube tube bank.
The heat exchanger schematic diagram that Fig. 3 finishes for assembling.
As shown in Figure 1, preferred forms of the present utility model is made up of two groups of heat exchanger tubes, and every group of heat exchanger tube comprises a thick heat exchanger tube 1 and restrained 5 by the thin heat exchanger tube of its containing.Two thick heat exchanger tubes put stator 3 at both ends, be with tens of fins 2 on the thick heat exchange pipe external surface, and fin 2 is for being equally spaced, and all fins 2 are parallel with stator 3.Connect with thick bypass pipe 6 in the end between the thick heat exchanger tube, connect with thin bypass pipe 7 between the tube bank.The water inlet 9 of thick heat exchanger tube is connected with the loop of delivery port 91 with the heating hot water pipe, the water inlet 8 of thin heat exchanger tube stretches out from the end of thick heat exchanger tube and links to each other with cold water inlet, and thin heat exchanger tube delivery port 81 stretches out from the end of thick heat exchanger tube and is connected with the bath hot water pipeline.The bypass pipe 7 of the water inlet 9 of thick heat exchanger tube and delivery port 91 and thin heat-exchanging tube bundle is at an end of heat exchanger, and the bypass pipe 6 of the water inlet 8 of thin heat exchanger tube and delivery port 81 and thick heat exchanger tube is at the other end of heat exchanger.
To be that a tubule is folding form thin heat-exchanging tube bundle 5 shown in Figure 2.
The heat exchanger that Fig. 3 finishes for assembling, there are tens of fins in the outer surface branch of thick heat exchanger tube.
The heat exchanger tube of this heat exchanger can have many groups, and quantity is decided according to the water capacity of gas heater, and heat exchanger tube and fin are copper.
