Abstract
The utility model relates to a heat exchanger including fins and pipelines. The heat exchanger also includes a box containing heat exchange medium. An annular pipeline is formed after one end of each pipeline penetrating through the box is connected with the other end of said pipeline disposed outside the box. The fins swell on the pipelines outside the box. The heat exchanger provided by the utility model has a characteristic of being high in heat exchange efficiency.
Description
Technical field
The utility model relates to a kind of heat exchanger.
Background technology
Heat exchanger is the most widely used a kind of heat transmission equipment in gas and liquid heat exchanger.The Hot water units that traditional heat pump heats, its heat exchange efficiency is lower.And while working, occur frosting situation under the environment temperature lower than 0 ℃, affected the normal work of unit, for a long time frosting causes the unit cannot hot water preparing.Mostly the method for conventional rack reply is to adopt the traffic direction of electric heated defrosting or reversion heat pump, and due under long low temperature environment, common electrically heated efficiency is low, and defrosting effect is poor; And the method for the traffic direction of the heat pump of taking to reverse, in the case of of short duration frosting, be feasible, but the unit working long hours under low temperature environment just there will be system inversion operation frequently, working life to unit has a great impact, and causes normally working.
Summary of the invention
For above-mentioned technical problem, main purpose of the present utility model is a kind of heat exchanger, the utlity model has the feature that heat exchange efficiency is high.
The technical scheme solving the problems of the technologies described above is as follows:
A kind of heat exchanger, comprise fin, pipeline, also comprise a casing, heat exchange medium is housed in casing, one end of pipeline is connected to form a circulating line, the part of fin swelling outside pipeline is positioned at casing with the other end being positioned at outside casing of pipeline from casing passes.Heat exchange medium in pipeline and casing carries out heat exchange, is conducive to accelerate the heat exchange of ducted heat exchange medium, and like this, the fin for swelling on pipeline, also can accelerate the heat exchange with air.Therefore, the utlity model has the feature that heat exchange efficiency is high.
Also comprise an electric heater unit, this electric heater unit comprises one or more heater strip, power supply and controller, and heater strip is together in series fin through fin successively, and the two ends of heater strip are connected with power supply, and power supply is connected with controller.When environment temperature is lower, by controller, switch on power, thereby make heater strip heating, fin is heated, to remove the frosting of fin surface, so that unit can normally be worked as early as possible, make the life-span of unit be guaranteed simultaneously.
Described controller comprises Temperature Detector, comparator, amplifier and relay, the output of Temperature Detector is connected with the input of comparator, the output of comparator is connected with amplifier, the output of amplifier is connected with the coil of relay, and the normally open contact of relay is connected in the loop that heater strip is connected with power supply.The environment temperature detecting by Temperature Detector is sent in comparator, compare with the temperature value of setting in comparator, if ambient temperature value is lower than setting value, comparator output heating signal, by amplifier, amplify rear drive relay, the coil of relay obtains electric, the normally open contact closure of relay, thereby power supply is heater strip power supply, to heat.If the temperature detecting is higher than the setting value in comparator, comparator can output signal not arrive amplifier, and the course of work of heating just can not occur yet.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
1 is fin, and 2 is pipeline, and 3 is casing, and 4 is heater strip, and 5 is power supply, and 6 is Temperature Detector, and 7 is comparator, and 8 is amplifier, and 9 is relay.
The specific embodiment
With reference to Fig. 1, a kind of heat exchanger of the present utility model, comprises fin 1, pipeline 2, also comprises a casing 3, and heat exchange medium is housed in casing.One end of pipeline 2 is connected to form a circulating line with the other end being positioned at outside casing of pipeline from casing passes, and fin 1 swelling is positioned at the part outside casing at pipeline 2.Also comprise an electric heater unit, this electric heater unit comprises one or more heater strip 4, power supply 5 and controller, and heater strip 4 is together in series fin through fin 1 successively, and the two ends of heater strip 4 are connected with power supply 5, and power supply is connected with controller.Described controller comprises Temperature Detector 6, comparator 7, amplifier 8 and relay 9, the output of Temperature Detector 6 is connected with the input of comparator 7, the output of comparator 7 is connected with amplifier 8, the output of amplifier 8 is connected with the coil of relay 9, and the normally open contact of relay 9 is connected in the loop that heater strip 4 is connected with power supply.
