Efficient heat exchanger employing reinforced spiral pipe

Abstract

The invention relates to an efficient heat exchanger employing a reinforced spiral pipe. The efficient heat exchanger comprises an outer pipe, and an inner pipe arranged in the outer pipe in a sleeved manner, wherein the inner pipe comprises two end parts and a multi-head spiral section pipe body arranged between the two end parts; the two ends of the inner pipe serve as a first fluid inlet and a first fluid outlet; the two ends of the outer pipe serve as a second fluid inlet and a second fluid outlet; a first fluid channel is formed in the inner pipe; and a second fluid channel consisting of multiple wave-shaped encircling concave-convex spiral channels is formed between the outer pipe and the inner pipe, and uniformly surrounds the first fluid channel according to the spiral trajectory. As the multi-head spiral section pipe body of the inner pipe is machined to a structure formed by spirally extending wave-shaped encircling concave-convex strip curved surfaces according to the spiral trajectory, and the outer wall or the inner wall of the multi-head spiral section pipe body has fin structures, the heat transfer efficiency is improved, the efficient heat transfer coefficient of the multi-head spiral pipe body is stabilized and continued, the heat exchange area of the outer surface of the inner pipe is effectively and obviously increased, and the heat exchange capacity of the heat exchanger is effectively improved.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a reinforced spiral tube high-efficiency heat exchanger for water source / ground source and heat pump water heaters. Background technique [0002] A reinforced spiral tube high-efficiency heat exchanger has excellent heat exchange performance and is a general-purpose equipment widely used in refrigeration and air conditioning, chemical industry, power and other fields. The casing heat exchanger currently used in the market has a simple structure and is easy to process, but the heat exchange raw material consumption per unit area is large, the manufacturing cost is high, the heat exchange is insufficient, and the efficiency is not high. Therefore, the raw material consumption per unit area is effectively reduced. It has become a key technology in the manufacture of heat exchangers to increase the heat exchange area and efficiency. [0003] In addition, the heat exchanger is also a major c...
