Pipe-communicated double-partition-wall heat transfer heat exchanger and manufacturing process thereof

Abstract

The invention discloses a pipe-communicated double-partition-wall heat transfer heat exchanger and a manufacturing process thereof. The heat exchanger comprises two or more tap water heat absorbing outer pipes, wherein the tips of the tap water heat absorbing outer pipes are fixedly connected with tap water heat absorbing outer pipe sealing heads; heat supply pipes are arranged in the tap water heat absorbing outer pipes; the tap water heat absorbing outer pipes are communicated with each other through a tap water communicating pipe; the heat supply pipes are communicated with each other through a heat supply pipe communicating pipe; a hot air inlet and a hot air outlet are fixedly communicated with the inlet ends and the outer ends of the heat supply pipes respectively; and a tap water inlet and a tap water outlet are fixedly communicated with the inlet ends and the outlet ends of the tap water heat absorbing outer pipes respectively. The heat exchanger is characterized in that: tap water heat absorbing inner pipes are arranged in a part of or all of the heat supply pipes, and are communicated with the cavities of the tap water heat absorbing outer pipes. The heat exchanger has the advantages of simple structure, easiness for welding kneading edges, high pressure bearing, no water leakage and high heat exchange efficiency.

Description

Technical field [0001] This patent involves a heating heat exchanger that can be heated on the heating pipe network and can be exchanged for hot water bath, especially a stainless steel pipe connecting double wall heat exchanges and its manufacturing process. Background technique [0002] The patent number applied for on March 10, 2007 was 200720019175.2, the authorized announcement number was CN20102875Y, and the practical new type was called "Anti -Stam -proof Cingewers".The original patented technologies are mostly water storage heat exchange structures. The shell is large and the diameter is thick. The purpose of the memory is used to relieve the progress of the cold water with the hot water of the memory and extend the exchange time of the exchange.Practice has proven poor results. Bathing needs to be a little bit of cold water. It does not need to be cold in the middle of the way, but it is not satisfactory.During the bathing time, one person cannot export heat water above ...
