Horizontal jacket water tank

Abstract

The invention discloses a horizontal jacket water tank, which comprises an outer shell (1), a medium circulation port and an inner lining jacket (2) for heat exchange, wherein the outer shell is provided with a medium pouring port (3) and a medium overflow port (4); the inner lining jacket (2) consists of an outer layer cylinder body and an inner layer cylinder body; the space in the inner liningjacket (2) serves as a heat exchange space; one end of the inner lining jacket (2) is fixedly welded with an expansion space (5); and a through hole (6) with a diameter of 6 mm is formed between the expansion space and the heat exchange space. As for the structure adopted by the horizontal jacket water tank, the damage caused by volume expansion of the medium does not directly act on the inner lining jacket to lighten the pressure on the inner lining jacket and eliminate potential safety hazards; and a liquid inlet of the medium enters the middle part of the inner lining jacket through a heat-conducting drainage tube to form a height difference with a liquid outlet so as to contribute to natural circulation and enhance the heat exchange effect of a water tank system.

Description

technical field

[0001] The invention relates to a water tank structure, in particular to a horizontal jacketed water tank. Background technique

[0002] With the popularity of solar water heaters, users have higher and higher requirements for the functions of water heaters. The structure of the solar water tank of the prior art generally includes a shell, water inlet and outlet pipes, a heat exchanger and an inner container. In addition to electric heating, this kind of water tank can also carry out medium circulation through the heat exchanger in the water tank, thereby improving the heat exchange effect of the water tank. At present, some heat exchangers adopt the structure of an inner tank jacket. The inner tank jacket is composed of an outer cylinder and an inner cylinder. The medium circulates between the outer cylinder and the inner cylinder, and the heat is transferred through heat conduction. Passed to the water in the liner. However, in the existing water tank wi...
