The invention provides a heat exchanger, and relates to the technical field of hot exchange devices. The hot exchanger comprises a cold fluid channel and a hot fluid channel. A stop part is arranged in the cold fluid channel and located in the fluid flowing direction in the cold fluid channel so that turbulent flow can be generated in the cold fluid channel. A stop part is also arranged in the hot fluid channel and located in the fluid flowing direction in the hot fluid channel so that turbulent flow can be generated in the hot fluid channel. A certain pressure is commonly set in the hot exchanger, cold fluid and hot fluid flow in the cold fluid channel and the hot fluid channel correspondingly, the stop parts change the fluid flowing direction, the fluid is prone to forming turbulent flow, and when the fluid flows in the form of turbulent flow, hot dissipation is conducted mainly in a turbulent flow manner, and the hot transmission efficiency is improved. Meanwhile, fluid is in turbulent flow, and the pressure drop losses of the fluid in the hot exchanger are low.
Description
technical field [0001] The invention relates to the technical field of heat exchange devices, in particular to a heat exchanger. Background technique [0002] Heat exchangers are generally used to remove heat from or add heat to a fluid or gas. One of the main design purposes of the heat exchanger is to improve the heat exchange efficiency. At the same time, a certain pressure is required to promote the flow of fluid in the heat exchanger, so a pump or other fluid pressure equipment will be applied in the heat exchanger to make the fluid pass smoothly. [0003] In the prior art, the flow form of the fluid in the inner cavity of the heat exchanger is mainly laminar flow, and the heat exchange efficiency is poor; or the surface area of the heat transfer element is increased in the heat exchanger to improve the thermal efficiency of the heat exchanger, but More pressure drop loss. Contents of the invention [0004] The purpose of the present invention is to provide a hea...
