Solar energy brazing laminating type heat exchanger

Abstract

The invention discloses a solar energy brazing laminating type heat exchanger which comprises main pieces and separation pieces, wherein each main piece is an aluminum plate, the front side of the main piece is separated to form two cavities including a left cavity and a right cavity, the lower ends of the two cavities are communicated with each other, two convex hulls, including a left convex hell and a right convex hull, are respectively arranged at the upper ends of the two cavities in a parallel mode, the left convex hull and the right convex hull are not communicated, a through hole is formed in the left convex hull, a side hole which is everted is formed in the right convex hull, the back faces of the two main pieces are contacted and are combined into a plate piece group, a plurality of plate piece groups are connected in series to form a group of serial spaces, hollows do not exist in the middle of the separation pieces, a plurality of the separation pieces are installed at the positions of a plurality of spaced main pieces in an alternate mode in the serial space, and a core body is formed by top-and-bottom cross laminating of two groups of the serial spaces. The solar energy brazing laminating type heat exchanger has the advantages of being good in heat transfer effect and high in whole strength, due to the fact that heat exchange is carried out outside a water storage device through a heat exchanger body, the solar energy brazing laminating type heat exchanger not only prevents water from being polluted, but also facilitates daily maintenance, repair and renewal, and saves a large amount of primary water stored in the water storage device and water for cleaning.

Description

technical field [0001] The invention relates to the technical field of heat exchange of solar water heaters, in particular to a solar brazed laminated heat exchanger. Background technique [0002] Solar water heater? It uses solar energy to convert heat energy to heat water from low temperature to high temperature to meet the needs of hot water in people's life and production. It mainly consists of heat collecting tubes, water storage devices (water tanks), and circulation tubes. A heater composed of roads and related accessories. It is one of the three major water heaters juxtaposed with gas water heaters and electric water heaters. [0003] Structurally, solar water heaters can be divided into: compact type and split type. Among them, the split type usually separates the heat collecting tube from the water storage device, and installs a built-in spiral heat exchanger in the water storage device. The heat fluid in the heat collecting tube passes through the heat exchanger...

AI Technical Summary

Problems solved by technology

[0004] Since the heat exchanger of the solar water heater is installed in the water storage device and is in direct contact with the water required by people, in order to prevent the rust of the heat exchanger from polluting the water, this type of heat exchanger is usually made of stainless steel or copper. , not only the product quality is heavy, the material cost is high, but also the pollution to the water body during the long-term use cannot be completely eliminated.

Also because the heat exchanger is installed in the water storage device, it is inconvenient when the heat exchanger needs to be maintained and repaired on a daily basis, and at the same time a large amount of original storage water and cleaning water of the water storage device will be wasted.
