Heat exchanger for dual spiral well

Abstract

The invention belongs to ground source heat pump engineering system corollary equipment and relates to a heat exchanger for a dual spiral well. The heat exchanger is composed of a coiled pipe, keels and reinforcement ribs and is characterized in that the coiled pipe is made of a metal pipe or plastic pipe subjected to antiseptic treatment in a coiled manner and comprises an inner spiral coiled pipe body and an outer spiral coiled pipe body; each keel is made of a metal plate or strengthened plastic plate subjected to antiseptic treatment, a reinforcement rib assembly hole is reserved in the middle of each keel, coiled pipe fixing holes are reserved in the two sides of each keel, and limiting devices are assembled at the two ends of each keel; each reinforcement rib is an arc screw, external threads are reserved at the two ends of each reinforcement rib, and each reinforcement rib is matched with a fastening screw; the multiple keels are fastened together through the reinforcement ribs via the reinforcement rib assembly holes to form a cylinder shape, and the inner spiral coiled pipe body is assembled on the inner sides of the keels and regularly clamped in the coiled pipe fixing holes in the inner sides of the keels; the outer spiral coiled pipe body is assembled on the outer sides of the keels and regularly clamped in the coiled pipe fixing holes in the outer sides of the keels; and the inner spiral coiled pipe body and a lower end opening of the outer spiral coiled pipe body are connected together in a communicating manner, and the corresponding limiting devices are assembled at the two ends of each keel. The heat exchanger can be stably arranged under water in the well, temperature exchange of a heat conduction medium in the coiled pipe and underground well water is completed, the required basic temperature is provided for a heat pump, and the effect of energy saving is achieved.

Description

[0001] Technical field [0002] The invention belongs to the auxiliary equipment of the ground source heat pump engineering system. Background technique [0003] Now, the energy-saving effect of ground source heat pump is very obvious, and it has been more and more recognized. Buried exchange pipelines are generally used in ground source heat pump assembly projects, but this method takes up too much land and is generally not easy to repair, and it is a one-time project. For single-family villas, well-type heat exchange is more practical, so it is particularly necessary to develop simple and practical well-type heat exchangers accordingly. Contents of the invention [0004] Aiming at the above requirements, this double helix well heat exchanger is specially designed. [0005] The solution of the present invention is: a heat exchanger for a double helix well, which is composed of a coil, a keel, and a reinforcing rib. Pipe and outer spiral coil; the keel is made of anti-cor...
