Problems solved by technology

If the gap between the baffle plate and the inner wall of the heat exchanger shell is too large, the leakage will be serious, the fluid will be short-circuited, the heat transfer efficiency will decrease, the energy consumption will increase, and it will easily cause vibration; When cleaning, the heat exchanger tube bundle cannot be easily pulled out of the shell or put into

Abstract

The invention discloses a shape memory alloy baffle heat exchanger. The heat exchanger comprises a barrel body, pipe boxes, baffles and a heat exchange pipe bundle. The pipe boxes are arranged on the two sides or one side of the barrel body. The upper baffles are attached to the top of the barrel body, the lower baffles are attached to the bottom of the barrel body, and the upper baffles and the lower baffles are arranged at intervals. The heat exchange pipe bundle is connected in connecting holes of the baffles in a penetrating mode. In addition, structural parameters and a preparation method for the shape memory alloy in the heat exchanger are provided.

Description

technical field [0001] The invention relates to a baffle heat exchanger, in particular to a shape memory alloy baffle heat exchanger and a method for preparing the shape memory alloy baffle. Background technique [0002] A heat exchanger is an energy-saving device that realizes heat transfer between materials, also known as a heat exchanger. It is widely used in industrial sectors such as chemical industry, petroleum, power and atomic energy. Its main function is to ensure the specific temperature required by the process for the medium, and it is also one of the main equipment to improve energy utilization. The floating head heat exchanger is the most widely used heat exchanger at present. One end of the heat exchanger tube sheet is fixed to the shell, and the tube sheet at one end can float freely in the shell. The floating head end is designed as a detachable structure, so that the tube bundle can be easily inserted or withdrawn from the shell, which is convenient for c...
