Pipe-communicating three-sleeve water storage secondary heating heat exchanger

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...

[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
