Modular non-water tank solar water heater

Abstract

The invention relates to a modular solar energy water heater without a water tank, which comprises vacuum glass insulation modules, wherein the vacuum glass insulation module is mainly composed of a glass vacuum pipe, a sealing pipe plug inserted in the mouth of the glass vacuum pipe, a water inlet pipe, a water outlet pipe and an electric heating pipe which penetrate through the sealing pipe plug, a pressure ring, an 'L'-shaped fastening seat, an elbow, a splicing head and polyurethane insulation blocks, the mouths of the water inlet pipe and the water outlet pipe extending out of the mouth of the sealing pipe plug are respectively connected with the elbow, and adjacent vacuum glass insulation modules are respectively spliced with a same splicing pipe via the splicing head. The modular solar energy water heater without a water tank utilizing a module splicing mode is convenient in mounting and maintenance, compact in structure, stable in sealing and fine safety property, can constantly provide hot water with stable temperature, can be perpendicularly and obliquely placed on the roof of a building, also can be mounted on a wall or be embedded in a wall of a building, is flexible in mounting, is convenient for forming a complete set with a building integrally, and is wide in application range.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a modular tankless solar water heater. Background technique [0002] Existing tankless solar water heaters use large-diameter glass vacuum tubes to form heat collectors that collect heat and store heat. The heat collection effect is better in the sun, and its volume is relatively smaller than that of traditional water heaters with water tanks. It can be integrated with buildings in multiple ways. supporting installation. However, in the existing water heaters without large-diameter glass vacuum tubes in the water tank, the glass vacuum tubes are heat collectors connected in series through "U" or "L" tubes at one time, which brings a lot of inconvenience to transportation and installation. Assembling at the installation site, the assembly is complicated and cumbersome, the sealing effect is not good, the maintenance is inconvenient, and there are potential safety hazards. In order to real...

Problems solved by technology

However, in the existing water heaters without large-diameter glass vacuum tubes in the water tank, the glass vacuum tubes are heat collectors connected in series through "U" or "L" tubes at one time, which brings a lot of inconvenience to transportation and installation. Assembled at the installation site, the assembly is complicated and cumbersome, the sealing effect is not good, the maintenance is inconvenient, and there are potential safety hazards

In order to realize the automatic control of water intake and discharge, the solar water heaters in the prior art are controlled by a water level detector or a water level probe placed in the water tank. Automatic control, concentrated function requirements, complex structure, high precision requirements, high cost, and inconvenient installation and maintenance
