Abstract

The invention discloses a temperature difference flow monitoring device for a refrigerant of a hydrogen ejector of a fuel cell, which belongs to the field of fuel cells. A fuel cell hydrogen ejector refrigerant temperature difference flow monitoring device, comprising a support base, a support frame, an ejector body and a liquid cooling mechanism, the base is fixedly connected with an arc-shaped slot, and the ejector body is placed on the On the arc-shaped slot, the base is provided with a cooling slot, the cooling slot is connected with the liquid cooling mechanism, the support frame is slidably connected with a threaded rod, and the threaded rod is fixedly connected with an arc-shaped slot, The arc-shaped card seat is in contact with the ejector body, a rotating shaft is rotatably connected to the support frame, and a cooling fan is fixedly connected to the rotating shaft; The fixed safety effect is achieved, and the ejector is dissipated at the same time, the service life of the ejector is improved, and the aging time of the ejector is reduced.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a device for monitoring the temperature difference flow of refrigerants in a hydrogen ejector of a fuel cell. Background technique [0002] The ejector is a device that uses a high-speed high-energy flow (liquid flow, air flow or other material flow) to eject another low-speed low-energy flow. Through the mixing effect of the boundary, the ejected jet transfers the energy to the ejected jet; the mixing area formed by blending gradually expands and fills the entire mixing chamber, and after a period of mixing process, to the outlet of the mixing chamber, the flow becomes almost a uniform flow; usually behind There is also a diffuser in order to reduce the flow rate and increase the static pressure, and the ejection air flow can be subsonic or supersonic; the ejection nozzle can be in the center of the pipe or around the pipe. In a gas flow system (such as a high-speed wind tun...
