Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Examples

A novel heat exchanger comprises an enclosing frame 1, wherein the enclosing frame 1 is a hollow cuboid. In the production process of the enclosure frame 1, the enclosure frame 1 can be obtained by bending and welding a whole stainless steel plate through a bending machine. Lifting lugs 6 are arranged at each top corner of the enclosure frame 1, and the lifting lugs 6 are used for fixing the heat exchanger in a gas water heater. The water tank is provided with 5 water tanks 4, wherein the top water tank 4 on one side is connected with a water outlet 2, and the bottom water tank 5 on the other side is connected with a water inlet 2. The water tank 4 is a concave water tank manufactured by stamping, wherein the opening of the water tank 4 is welded on the side wall of the enclosure frame 1 in a sealing manner, so that welding spots of the water tank 4 can not directly contact with flame inside the enclosure frame 1, and the durability of the water tank is improved. The enclosure frame 1 is provided with a plurality of layers of heat conduction pipes 8, and the installation mode of each layer of heat conduction pipe 8 tends to be dense from top to bottom. The heat conducting pipe 8 passes through the middle of the enclosure frame 1 and is communicated with the corresponding water tanks 4 at two sides. Besides the pipeline ports of the water outlet 2 and the water inlet 3 which are connected to the water tank 4, the pipeline ports of more than or equal to 2 heat conduction pipes 8 are also connected to the water tank 4, and all the water tanks 4 are communicated through the heat conduction pipes 8, so that water entering from the water inlet 3 can be discharged from the water outlet 2 after being heated.

In this embodiment, referring to fig. 2, three rows of heat pipes 8 are installed in the enclosure frame 1 from top to bottom, wherein the heat pipe 8 at the topmost layer is installed sparsely, so that the topmost layer directly contacts the hot fluid generated by the gas fire exhaust, and the hot fluid directly exchanges heat with the liquid in the heat pipe 8. Then, because the top is closed, the hot fluid moves from top to bottom, and after the hot fluid exchanges heat with the middle-layer heat-conducting pipe 8, the residual hot fluid is mainly flue gas, and the flue gas exchanges heat with the lowest-layer heat-conducting pipe 8. It should be noted that the lowermost duct 8 is sufficiently dense to facilitate heat exchange with the flue gases.

The lower part of the enclosure frame 1 is provided with a flue gas outlet 7, and the flue gas outlet 7 is provided with a diversion trench. The flue gas is discharged from the flue gas outlet after heat exchange is carried out on the intensive heat conduction pipe 8 at the lowermost layer. In the process of heat exchange of the heat conduction pipe 8, the generated condensed water flows downwards under the action of gravity and drops onto the diversion trench, so that the reduction of the heat efficiency of the heat exchanger caused by the circulation evaporation of the condensed water is avoided.

In this embodiment, the heat pipe 8 is a copper heat pipe with an oval cross section, and when it is installed, the long axis of the oval is installed horizontally, and compared with the conventional round pipe, the oval shape has a stronger barrier to fluid in the vertical direction, and the gas staying time beside the oval pipe is longer under the same hot gas flow, so the oval pipe has higher thermal efficiency.

The heat conducting fins 5 are arranged on the heat conducting pipes 8, the heat conducting fins 5 are metal sheets welded on the heat conducting pipes 8, and materials the same as the heat conducting pipes 8 are adopted for facilitating the welding process in production. The heat conductive sheet 5 can further improve the heat exchange rate of the heat conductive pipes 8.

The use principle is as follows: when the water heater is used, water to be heated is filled through the bottom water inlet 3, the water passes through the water tank 4 and the heat conduction pipe 8, and is discharged from the water outlet 2 at the top after heat is absorbed, hot fluid generated by gas fire is discharged from top to bottom, and finally only residual flue gas is discharged from the bottom flue gas outlet 7, and condensed water generated when the heat exchange is carried out with the heat conduction pipe is also discharged from the diversion trench.

It should be noted that all the parts of the new heat exchanger are made of stainless steel material, which allows the overall cost to be effectively controlled.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
