Abstract
The utility model discloses an external heat exchanger for a water heater. Two spiral grooves matching with heat conducting pipes are respectively arranged on the inner barrel wall and at the bottom of a water tank, and the heat conducting pipes are embedded into the grooves of the inner barrel wall and the bottom of the water tank, thereby the external heat exchanger greatly enlarges contact areaamong the heat conducting pipes and the inner barrel wall of the water tank, effectively improves heat exchange efficiency and shortens time for heating domestic water.
Description
Technical field
The utility model relates to a kind of heat exchanger, relates in particular to a kind of external heat exchanger that is used for water heater.
Background technology
Common on the market water heater external heat exchanger, be on the water tank inner barrel wall, to twine heat pipe, the liquid that the temperature that flowing inside the heat pipe is higher or the working media of gas, the water of heat bucket the inside in the higher heat pipe of temperature is delivered to the lower water tank of temperature, thereby water heating with bucket the inside in the water tank, but the inner barrel wall of its water tank is level and smooth, makes that the contact area of water tank inner barrel wall and heat pipe is less, and heat exchanger effectiveness is lower.The utility model has effectively solved above deficiency, on the water tank inner barrel wall, respectively be provided with a spiral groove that is complementary with heat pipe with the bottom, heat pipe is embedded in the groove of water tank inner barrel wall and bottom, increased the contact area of heat pipe and water tank inner barrel wall greatly, improve the efficient of heat exchange effectively, shortened the time of heating domestic water.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of external heat exchanger that is used for water heater, on the water tank inner barrel wall, respectively be provided with a spiral groove that is complementary with heat pipe with the bottom, heat pipe is embedded in the groove of water tank inner barrel wall and bottom, increased the contact area of heat pipe and water tank inner barrel wall greatly, improve the efficient of heat exchange effectively, shortened the time of heating domestic water.
The utility model is achieved in that the utility model comprises: bucket, heat pipe, inner barrel wall groove, heat conductive silica gel, heat-insulation layer, tank shell in the hot-water outlet, water tank, advance cold water outlet; Tank shell inside is bucket in the water tank, be heat-insulation layer between the bucket in tank shell and the water tank, twining heat pipe on water tank inner barrel wall and the bottom, heat pipe is embedded in the groove of water tank inner barrel wall and bottom, is heat conductive silica gel between the groove of heat pipe and water tank inner barrel wall and bottom; Domestic water is equipped with in the bucket the inside in the water tank, and the top of bucket has the hot-water outlet in water tank, and the bottom of bucket has into cold water outlet in water tank.The liquid that the temperature that flowing inside the heat pipe is higher or the working media of gas, after the advancing cold water outlet and enter cold water of bucket in the water tank, heat is delivered to the domestic water of bucket the inside in the lower water tank of temperature from the higher heat pipe of temperature through the heat conductive silica gel between heat pipe and the inner barrel wall groove, the lower domestic water of temperature is through overheated transmission, temperature raises, the higher life of temperature is flowed out with hot water hot-water outlet of bucket in the water tank, uses for daily life.
The utility model is simple in structure, increases the contact area of heat pipe and water tank inner barrel wall greatly, has improved the efficient of heat exchange effectively, has shortened the time of heating domestic water.
Description of drawings
Fig. 1 is the schematic diagram that twines heat pipe on the utility model inner barrel wall.
Fig. 2 is the utility model generalized section.
Fig. 3 is a bucket concave surface enlarged drawing in the water tank.
Among the figure: 1, hot-water outlet, 2, bucket in the water tank, 3, heat pipe, 4, the inner barrel wall groove, 5, heat conductive silica gel, 6, heat-insulation layer, 7, tank shell, 8, advance cold water outlet.
The specific embodiment
As Fig. 2, shown in Figure 3, present embodiment comprises: bucket 2, heat pipe 3, inner barrel wall groove 4, heat conductive silica gel 5, heat-insulation layer 6, tank shell 7 in the hot-water outlet 1, water tank, advance cold water outlet 8.Wherein tank shell 7 inside are buckets 2 in the water tank, are heat-insulation layers 6 between the bucket 2 in tank shell 7 and the water tank, are twining heat pipe 3 on the water tank inner barrel wall, and heat pipe 3 is embedded in the water tank inner barrel wall groove 4, is heat conductive silica gel 5 between heat pipe 3 and the water tank inner barrel wall groove 4; Domestic water is equipped with in bucket 2 the insides in the water tank, and 2 tops of bucket have hot-water outlet 1 in water tank, and the bottom of bucket has into cold water outlet 8 in water tank.The higher gas working dielectric of temperature is flowing in heat pipe 3 the insides, after the advancing cold water outlet 8 and enter cold water of bucket 2 in the water tank, heat is delivered to the domestic water of bucket 2 the insides in the lower water tank of temperature from the higher heat pipe 3 of temperature through the heat conductive silica gel 5 between heat pipe 3 and the inner barrel wall groove 4, the lower domestic water of temperature is through overheated transmission, temperature raises, the higher life of temperature is flowed out with hot water hot-water outlet 1 of bucket 2 in the water tank, uses for daily life.
Claims (2)
