Description

An air energy water heater outer plate high efficiency heat exchanger water tank

technical field

The utility model relates to an air energy water heater device, in particular to an air energy water heater outer disk high-efficiency heat exchanger water tank.

Background technique

There are two main types of water tanks for existing air energy heat pump water heaters. One is a coil heat exchanger made of copper tubes wound into a spring shape, which is placed in the water tank and connected to the heat pump at both ends to form a circulating closed circuit system. One is to directly wrap the steel pipe around the outer surface of the water tank, and connect both ends with the heat pump to form a circulating closed-circuit system. The first structure, because the coil heat exchanger is in direct contact with water, the scale generated by hot water has a strong corrosion effect on it, making its service life very short. In the second structure, although the coil is not in direct contact with the water, because it conducts heat indirectly through the water tank wall, the contact area between the coil and the water tank wall determines the heat exchange effect, and this structure is a single-tube coil On the surface of the water tank, the contact area with the wall of the water tank is limited, which seriously affects the heat transfer effect.

Utility model content

The purpose of the utility model is to provide a high-efficiency heat exchanger water tank with an outer disk of an air energy water heater, which has a simple structure, a large contact area between the coil pipe and the wall of the water tank, good heat exchange effect, and enhanced the service life of the water tank.

In order to solve the existing problems of the background technology, the utility model adopts the following technical solutions:

A high-efficiency heat exchanger water tank for an outer disk of an air-energy water heater, including a water tank body, the inner wall of the water tank body is provided with a spiral annular groove, and a heat transfer medium coil with an outer diameter equivalent to the groove is arranged on the spiral annular groove , the inlet and outlet ends of the heat transfer medium coil are respectively provided with heat transfer medium coil joints, one side of the water tank body is provided with hot water pipe joints, and the lower end of one side of the water tank body is provided with cold water pipe joints. An insulating layer is provided between the inner wall and the outer wall of the box body.

The spiral lower end of the heat transfer medium coil is connected with a storage room, and the storage room is connected with a heat transfer medium coil joint, and the heat transfer medium coil joint protrudes from the lower end of the water tank inside the tank body.

The heat transfer medium coil is composed of 2 to 6 parallel metal tubes. The two ends of the metal tubes are connected together by the heat transfer medium coil joints and wound in the spiral groove of the water tank.

The inner surface of the water tank body is made into a spiral groove that is equivalent to the outer diameter of the heat transfer medium coil. The heat transfer medium coil is composed of 2 to 6 parallel metal tubes, and the two ends are respectively connected by the heat transfer medium coil joints. Collected together, wound in the spiral groove of the water tank, so that the single tube becomes a multi-tube, and embedded in the spiral groove, greatly improving the contact area with the water tank wall, the heat transfer medium coil joints are respectively connected through the The pipe is connected with the heat pump host to form a closed-circuit system, and the closed-circuit system is filled with heat transfer medium. When the heat pump starts to work, the compressor in the heat pump host continuously presses the heat transfer medium that has absorbed heat and vaporized in the evaporator into the heat transfer medium coil until the gas is compressed into liquid and releases heat. The flow valve flows into the evaporator to vaporize and absorb heat. So the heat is transferred to the water tank again and again.

Beneficial effects of the utility model: the utility model has a simple structure, a large contact area between the coil pipe and the wall of the water tank, good heat exchange effect, and enhanced service life of the water tank.
