Abstract

The utility model relates to a radiating heat-exchanger with internal coil-pipe, comprising a U-shaped communicating pipe 1, a heat absorption straight tube 3, a heat absorption fin 4, an inlet and outlet water pipe 6 and a pressing block 7. The connection mode and mounting position between the former parts and the casing are the same with the existing heat exchanger of various domestic gas water-heater sold in market. The utility model has the technical proposal that the copper tube 2 coiled the shell of the heat exchanger tightly are completely changed to the coiling on the inner wall of the tank shell; so the radiant heat produced by the burner can be directly absorbed by the copper tube to achieve the purposes of saving energy, economizing copper material and enhancing the heat efficiency.

Description

Radiating heat-exchanger with internal coil-pipe

The utility model relates to a kind of heat exchanger that is used for domestic gas instantaneous water heater.

At present, heat exchanger in the domestic gas instantaneous water heater of the domestic various trades mark has a common ground to be that coiling has 2-4 circle copper pipe on the tank shell lateral wall, make copper pipe can not directly absorb the radiant heat that burner produces like this, cause the thermal efficiency low, waste energy.

The purpose of this utility model is to provide a kind of can directly absorb photothermal heat exchanger.

Order of the present utility model is to realize like this, that is: this inner coil pipe radiant type heat exchanger, comprise " U " type communicating pipe, heat absorption straight tube, absorb fin, tank shell, water inlet pipe and water outlet pipe and briquetting, its key is that on the tank shell madial wall, between heat absorption fin and burner, coiling is connected with 2-4 circle copper tube.So just, be that copper tube directly absorbs all over the radiant heat that burner is produced, thereby greatly improve its thermal efficiency, reach energy-saving and cost-reducing purpose, and do not hinder rigidity in tank shell.

The utility model detects through the contrast of Chongqing City's gas appliance quality monitoring measuring station and shows, before being unkitted this heat exchanger, the thermal efficiency of certain water heater only is 81.4%, on changing the outfit on this water heater behind the utility model, the thermal efficiency just reaches more than 87.5%, and its carbon monoxide content only is 0.0174%, and hot water output has also improved 1.8%, in addition because tank shell inwall coiling copper tube consumes the copper material much less than it in outer wall coiling institute, so can save a large amount of copper materials.

Concrete structure of the present utility model is provided by the following drawings.

Fig. 1 is a general structure schematic diagram of the present utility model;

Fig. 2 is Figure 1A-A cutaway view;

Fig. 3 is Fig. 2 B-B cutaway view;

Fig. 4 is Fig. 2 C-C cutaway view.

Below with reference to accompanying drawing concrete structure of the present utility model is further described.

Referring to Fig. 1-4, the utility model inner coil pipe radiant type heat exchanger, comprise " U " type communicating pipe 1, heat absorption straight tube 3, heat absorption fin 4, water inlet pipe and water outlet pipe 6, briquetting 7, their installation sites on tank shell 5 and identical with the heat exchanger of present commercially available various domestic gas instantaneous water heaters with the connecting mode of tank shell, its key is the former outer copper tube 2 of heat exchanger tank shell that tightly is coiled in is all changed on the tank shell madial wall and coiling, and according to the varying in size of water heater aquifer yield, coiling 2-4 circle.

Claims

1, a kind of inner coil pipe radiant type heat exchanger, comprise " U " type communicating pipe, heat absorption straight tube, heat absorption fin, tank shell, water inlet pipe and water outlet pipe and briquetting, it is characterized in that on the tank shell madial wall between heat absorption fin and burner, coiling is connected with 2-4 circle copper tube.
