Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Such as figure 1 and figure 2 As shown, a double-channel energy storage heat exchanger includes a shell-and-tube heat exchanger. The shell-and-tube heat exchanger includes a shell 13 with a number of baffles 5 inside, and is arranged through flange connection. In the tube box 6 at the upper and lower ends of the housing 13, a number of heat exchange tubes 12 arranged in the housing 13 and communicated with the tube box 6 at the upper and lower ends are provided. The plate 2 is used to divide the heat exchange tube into an inlet section and an outlet section. The fluid flows from the tube box connecting pipe 1 of the upper tube box 6 through the inlet section, and turns back in the lower tube box 6 to flow into the inlet and outlet sections to complete the tube flow. The partition plate 5 is welded in the shell 13, and is use...

Abstract

The invention discloses an energy-storage heat exchanger with double flow channels. The heat exchanger comprises a pipe-shell heat exchanger body, the pipe-shell heat exchanger body is provided with ashell body, pipe boxes and a plurality of heat exchange pipes, wherein the shell body is internally provided with a plurality of baffling partition plates, the pipe boxes are arranged at the upper end and the lower end of the shell body through flanges, and the plurality of heat exchange pipes are arranged in the shell body in an array mode and communicate with the pipe boxes at the upper end andthe lower end of the shell body; and the heat exchange pipes are sleeved with annular sleeve pipes, and gaps between the inner holes of the annular sleeve pipes and the outer walls of the heat exchange pipes are hermetically filled with phase change materials. Compared with a traditional pipe-shell heat exchanger body, the energy-storage heat exchanger has the higher energy storage capacity, andthe problem that energy is distributed unevenly in time can be effectively solved; compared with the design of a single-flow channel energy storage heat exchanger, the design of the double flow channels has the more flexible operability, and the double flow channels can meet the requirements that the system performs energy storage and heat release operation at the same time; and the heat exchangeris suitable for the fields of industrial waste heat recovery, solar heat storage, heat pump water heaters combining peak valley electricity heating and the like.

Description

technical field [0001] The invention relates to a double-channel energy storage heat exchanger, which is used for heat energy storage and reuse, and belongs to the field of energy conservation and environmental protection. technical background [0002] In recent decades, with the continuous growth of the economy, the consumption of resources has been increasing, and energy conservation and environmental protection have also been paid more and more attention. Higher requirements are put forward for the improvement of energy utilization rate and the application of renewable energy. Therefore, the development of energy storage devices has received widespread attention. The energy storage device can solve the problem of uneven energy distribution in time, and balance the situation that the energy is inconsistent with the user's demand. Therefore, it is urgent to design and develop an energy storage system with strong stability, high utilization rate and high heat storage densi...
