Abstract
The utility model relates to a heat exchanger with anti-freezing function, which comprises a combustion chamber, heat exchange fins and a heat exchanger water pipe, and is characterized in that the heat exchanger water pipe is at least communicated with a section of anti-freezing pipe, and the tail end of the anti-freezing pipe is sealed; the extending direction of the tail end of the anti-freezing pipe is upward. The anti-freezing pipe of the utility model is provided with one or more sections of anti-freezing pipes on the water pipe of the heat exchanger, when the indoor temperature is lower than 0 ℃, the anti-freezing pipes provide an extension space for the volume expansion of ice, and the water pipe of the heat exchanger can be effectively protected from frost cracking; the utility model discloses simple structure even structurally improves at current gas heater, and it is also very convenient to implement, and the experiment proves that be applicable to current most gas heater, and the range of application is wide, and is with low costs, and the prospect is better.
Description
[technical field]
The present invention relates to the gas heater field, especially relate to the heat exchanger of gas heater.
[background technology]
In modern society, the use of gas heater is subjected to users' welcome deeply, brings great convenience for people's bath water, heating water etc.Yet, in the winter of northern China, the temperature in overwhelming majority area is in one long period, all be in below 0 ℃, though it is indoor that gas heater generally is installed in, but its blast pipe is in communication with the outside, and outdoor cold air usually makes indoor gas and hot water actuator temperature reach below 0 ℃, makes water pipe from freezing crack wherein.Though relief valve all is installed on the gas heater; but must allow the user close preceding gate valve; unload relief valve; the venting wherein water in the water pipe just can play antifreeze effect; and the user usually can forget the operation of this protectiveness; cause the bursting by freezing of water pipe in the gas heater, make troubles and lose, also bring loss to manufacturer to user life.
Antifreezing measures in this respect generally adopt the electrical heating antifreezing system at present, promptly electric heating tube is installed at some position of water pipe in gas heater, and this measure can be played antifreezing effect, but its cost height, power consumption is many, and just can not bring into play its antifreeze function when taking place to have a power failure.
[summary of the invention]
The present invention has overcome the deficiencies in the prior art, and a kind of simple in structure, easy to implement, cost is low, resistance to frost is good heat exchanger is provided.
In order to solve the technical problem of above-mentioned existence, the present invention adopts following technical proposal:
A kind of heat exchanger with antifreeze function comprises combustion chamber, heat exchanger fin, heat exchanger water pipe, it is characterized in that the heat exchanger water pipe is communicated with the anti-frozen pipe of a joint, the end seal of anti-frozen pipe at least;
The terminal direction of extension of aforesaid anti-frozen pipe is for making progress;
Aforesaid anti-frozen pipe is two joints, and anti-frozen pipe is communicated with the welding of heat exchanger water pipe;
Also be provided with arm on the aforesaid anti-frozen pipe, the arm end seal.
The present invention compared with prior art has following advantage: anti-frozen pipe of the present invention is to be provided with a joint or the anti-frozen pipe of more piece on the heat exchanger water pipe, when indoor temperature is lower than 0 ℃, anti-frozen pipe provides extending space for the volumetric expansion of ice, can effectively protect the heat exchanger water pipe to avoid bursting by freezing; The present invention is simple in structure, even improve on existing gas heater structure, implements also very convenient, the experiment proved that to be applicable to existing most gas heater, and applied range, cost is low, and prospect is better.
[description of drawings]
Fig. 1 is the front schematic view of structure of the present invention;
Fig. 2 is the side schematic view of structure of the present invention.
[specific embodiment]
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
See Fig. 1,2, a kind of heat exchanger with antifreeze function comprises combustion chamber 1, heat exchanger fin 2, heat exchanger water pipe 3, and the heat exchanger water pipe is communicated with the anti-frozen pipe 4 of a joint, the end seal of anti-frozen pipe at least.
Anti-frozen pipe end be sealing state, is not full of water in the anti-frozen pipe, and the inside accommodates air, can utilize and prevent the air pressure that exists in the frozen pipe, and the water heater of prevention duty, current are the least possible to enter anti-frozen pipe; When the water in the heat exchanger water pipe freezed, the cavity that is full of air in the anti-frozen pipe can be used as the extending space because of icing volumetric expansion.
Anti-frozen pipe can be two joint or more pieces, and anti-frozen pipe is communicated with the welding of heat exchanger water pipe; More piece is prevented frozen pipe, and more anti-expansion space is arranged.Can also be provided with arm on the anti-frozen pipe, arm end seal (not shown), a plurality of arms have more anti-expansion space.Anti-frozen pipe can be arranged on the top of heat exchanger, also can be arranged on the bottom of heat exchanger.
The terminal direction of extension of anti-frozen pipe 4 is for making progress.The terminal direction of extension of described anti-frozen pipe is the top of structure, and when making water heater in working order, current are the least possible to enter anti-frozen pipe.
