Problems solved by technology

[0002] At present, in the field of domestic heating conversion water heaters (collectively referred to as heat exchangers) in circulation in the market, the technical characteristics of the heat exchangers are generally a cold water large pipe sleeve heating small pipe channel water storage structure. The short-term thermal efficiency is low, the cold medium is heated slowly by a heating pipe channel, and the heat conduction time is long. When the hot water stored in the heat exchanger is used up, there will be rounds of reheating, and it is necessary to wait for the heating time, which cannot meet the needs of the bathing process. The water consumption, its shortcoming can not flow out hot water continuously to solve the problem of water for bathing, therefore, there are defects in the prior art

Embodiment 1

[0037] 1. In the present invention, the tube is connected to the three-tube water storage secondary heating heat exchanger, such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 15 , Figure 16 As shown, the two ends of the plurality of cold water pipes 1 press the pipe wall on the arc surface to form a plane platform 10, and then set and press the shell tube flange hole 12 on the plane platform 10 successively; the shell tube flange hole 12 faces on the flat plate The outer flanging opening is a straight wall and a flat opening, which is the shell tube valgus hole 16; the shell tube valgus hole 16 is connected to the mouth of the adjacent cold water pipe 1 shell tube valgus hole 16, and the hole is directly welded to connect multiple branches The cold water pipe 1 is an integral cold medium channel, which is combined into a counterflow or mixed flow structure of cold fluid. The cold water pipes 1 that do not need openings at one end of t...

Embodiment 2

[0048] Such as image 3 , Figure 10 As shown, the heating pipe 11 arranged in the lumen of the cold water pipe 1 side is a thick pipe, and the diameter is selected to be 51-63 mm, and the straight diameter of the other heating pipes is 32-38 mm. The straight diameter of the pipe 23 is 19-25mm; the thick heating pipe 11 in the inner cavity of the cold water pipe 1 is combined with the straight pipe of the heating communication pipe or the elbow pipe of the heating communication pipe. The heating pipe is convenient to directly pass through the 8mm thin tube and the 6m long cold water heat-absorbing pipe 3 is convenient to insert and connect; when the heat exchanger is installed vertically, the thick heating pipe has a large air capacity, and the gas entering the heat exchanger from the pipe network is not easy to block the hot fluid channel , does not affect the heating fluid circulation or the advantages of convenient exhaust through the exhaust valve; in the prior art, the v...

Embodiment 3

[0053] Such as Figure 5 , Figure 6 , Figure 10 As shown, one port of the cold water heat-absorbing pipe 3 is welded and fixedly connected with the cold water pipe connecting hole 14 on one end wall of the heating pipe 11 to communicate with the lumen of the cold water pipe 1, and the other end is airtightly welded and fixedly connected to the other end wall of the heating pipe to connect the cold water outlet pipe The joint is airtightly connected with the wall of the cold water pipe 1 to form a cold medium flow channel; or the cold water pipe welding hole 14 is punched on the heating pipe blocking plate 4, and the cold water on the two ports of the cold water heat-absorbing pipe 3 and the heating pipe blocking plate 4 The pipe welding hole is welded and fixedly connected. One port communicates with the inner cavity of the cold water pipe 1, and the other port communicates with the cold water outlet pipe joint 7, the pipe wall of the cold water pipe 1 or the shell pipe hea...

Abstract

The invention discloses a pipe-communicating three-sleeve water storage secondary heating heat exchanger. A plurality of cold water pipes are connected and communicate in a sealed manner. At least oneheating pipe is arranged in pipe cavities of the plurality of cold water pipes, and the plurality of heating pipes are connected and communicate with one another ni a sealed manner. A cold water heatabsorption pipe is arranged in a pipe cavity of at least one heating pipe. The cold water heat absorption pipe inserted into the pipe cavity of the heating pipe is fixedly connected and communicate with the inner cavity of the corresponding cold water pipe in a sealed manner to form a three-sleeve cold medium secondary continuous heating fast channel. A shell pipe end socket blocking plate is fixedly connected with and blocks the port part of each cold water pipe in a sealed manner. A cold water inlet pipe connector, a cold water outlet pipe connector, a warm air inlet pipe connector and a warm air outlet pipe connector are fixedly connected to each cold water pipe or each shell pipe end socket blocking plate in a sealed manner. The heat exchanger is compact and simple in process structure, the flowing path of a pipe-communicating three-sleeve secondary heating changing cold medium channel is lengthened, the flowing speed of a cold medium is limited, the heating residence time of coldfluid is prolonged in the cavities of the cold water pipes, exchange hot water of the heat exchanger continuously flows out, and the bathing requirements of users are met.

Description

technical field [0001] The invention relates to the field of heating and ventilating technology, and uses a domestic heating heat source to exchange hot water for a household heating conversion water heater, in particular to a secondary heating of water stored in a three-pipe tube connected by stainless steel, low-carbon steel, or copper or aluminum tubes Heat Exchanger. Background technique [0002] At present, in the field of domestic heating conversion water heaters (collectively referred to as heat exchangers) in the market, the technical characteristics of the heat exchangers are generally the cold water large pipe sleeve heating small pipe channel water storage structure. The short-term thermal efficiency is low, the cold medium is heated slowly by a heating pipe channel, and the heat conduction time is long. When the hot water stored in the heat exchanger is used up, there will be rounds of reheating, and it is necessary to wait for the heating time, which cannot meet...
