Abstract
The utility model relates to a runner frost crack prevention device which comprises a runner main body; the runner main body installed with a water-proof elastic material; and when the water in the runner expands under low temperature, the enlarged volume of the runner main body presses the elastic material to contract, thus avoiding the tube from breaking due to the expansion, and protecting the runner. The runner frost crack prevention device has simple structure, good protective effect and low manufacturing cost. The utility model also discloses a heat exchanger with the runner frost crack prevention device, comprising a main body which is internally provided with a water channel, wherein the water channel is provided with the water-proof elastic material and further provided with an inner groove; the opening of the inner groove is communicated with the water channel; the water-proof elastic material is arranged in the inner groove; and the design ensures the sectional area of water flow of the runner to the uttermost.
Description
Technical field
The utility model relates to the anti-bursting by freezing device of a kind of runner and has the heat exchanger of this anti-bursting by freezing device.
Background technique
In the bigger place of climatic change, as northern China, winter, temperature was lower, thereby the fluid in the pipeline freezes easily pipeline is burst, it mainly is that pipeline is incubated heating that existing freezing prevention tubing splits measure, makes the current can freezing expansion, but the cost that this mode consumed is bigger.In addition, pipeline can be occurred on the water pipe of some cold and warm exchanger equally by the phenomenon of bursting by freezing, causes equipment to be damaged.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of anti-bursting by freezing device of runner simple in structure, that cost is low and a kind of heat exchanger with the anti-bursting by freezing device of runner.
The technological scheme that the utility model adopted is:
A kind of runner is prevented the bursting by freezing device, comprises the runner main body, and described runner main body is equipped with the water-proof elastic material.
Further improvement of the utility model, described water-proof elastic material are annular and the internal surface of being close to the runner main body.
The invention also discloses a kind of heat exchanger with the anti-bursting by freezing device of runner, comprise main body, be provided with flow channel in the main body, described flow channel is provided with the water-proof elastic material.
Further improvement of the utility model, described water-proof elastic material is located at the inwall of flow channel.
Further improvement of the utility model, described flow channel is provided with inner groovy, and the opening of inner groovy is communicated with flow channel, and the water-proof elastic material is loaded in the inner groovy.
The beneficial effects of the utility model are: the design is equipped with elastic material in water flow passage; when the water in the runner during at low-temperature expansion; the volume compressing elastic material of its increase; elastic material is shunk, effectively held the volume that increased of water when expanding, thereby avoided body to be burst; protected fluid line; the utility model is simple in structure, protect effective, low cost of manufacture.The design also can be applicable in the heat exchanger; can effectively protect equally heat exchanger not by; the water-proof elastic material removes the inwall that can be located at flow channel; also can on flow channel, be provided with opening inner groovy inwardly; the water-proof elastic material is loaded in the inner groovy; not only easy for installation, and guaranteed that to greatest extent the water flow section of runner is long-pending.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
