Description

A vacuum insulation heat pipe solar water heater

technical field

The utility model relates to a vacuum heat preservation heat pipe type solar water heater.

Background technique

In the prior art, the manufacture of the heat collecting tube of the vacuum heat collecting tube solar water heater requires dozens of processes, and the connection of the heat collecting tube and the water storage tank requires complex seals, resulting in complex processes, increased costs, and low thermal efficiency. Seasons are also prone to frost cracks.

Utility model content

The purpose of the utility model is to solve the above-mentioned problems against the deficiencies of the prior art, and provide a vacuum heat-insulating heat pipe solar water heater with high heating efficiency, simple process and low cost.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a vacuum heat-insulation heat pipe solar water heater, including a flat heat pipe heat collector heat exchanger, a water storage tank, a vacuum insulation layer and an insulation layer; The heat exchanger includes a heat collection part outside the water storage tank and a heat exchange part inside the water storage tank; the vacuum insulation layer is arranged on the light-facing surface of the heat collection part; the insulation layer is arranged on the heat collection part Backlit face and water tank exterior.

The water storage tank of the utility model is provided with fins for increasing the heat dissipation area of the flat heat pipe heat collector heat exchanger, and the flat heat pipe heat collector heat exchanger is connected to the fins.

The flat heat pipe heat collecting heat exchanger described in the utility model is a hollow body sealed by two layers of metal plates, with two mesh supports sandwiched in the middle of the hollow body, and a heat medium is added in the hollow body and vacuumized.

The flat heat pipe heat collector and the water storage tank described in the utility model have an integrated structure.

The insulation layer described in the utility model is a foam plastic layer.

The vacuum insulation layer described in the utility model is a glass plate and a mesh support. The mesh support is arranged between the glass plate and the flat heat pipe heat collector and heat exchanger, and between the glass plate and the flat heat pipe heat collector. Seal and vacuum.

The light-facing surface of the heat pipe heat collector heat exchanger described in the utility model is coated with a black coating.

Compared with the prior art, the utility model has the following advantages:

1. Due to the use of the heat pipe effect, the thermal efficiency is dozens of times that of the vacuum tube water heater.

2. Since the water is not directly heated by the vacuum tube, the water is placed in an insulated water storage tank for indirect heating, which solves the problem of antifreeze very well.

3. The plate type heat pipe collector heat exchanger is welded by ordinary metal plates, the process is simple, and the cost is extremely low.

The technical solutions of the present utility model will be further described in detail through the drawings and embodiments below.
