Embodiment Construction
[0014] Hereinafter, the present invention will be described in more detail with examples in conjunction with the accompanying drawings:
[0015] Combine Figure 1~3 , The present invention includes a chip 1 in an eccentric dispenser, a heat sink 2, a water inlet 3, a water outlet 4, a smooth arc surface 5, a parallel plate 6, and a jet hole 7.
[0016] The two ends of the heat sink 2 are composed of a water inlet 3 and a water outlet 4, and the water inlet 3 and the water outlet 4 are arranged on the same side of the heat sink 2.
[0017] The arc curved surface 5 is respectively tangent to the parallel plate 6 and the inner wall of the radiator, and is smoothly connected.
[0018] The parallel plates 6 are vertically distributed at equal distances, and the horizontal distances between the two ends of the parallel plates 6 and the inner wall of the heat sink 2 are equal.
[0019] On the parallel plate 6 and the arc curved surface 5, the adjacent horizontal distribution distance is equal...

The invention aims at providing an injection allocator control unit with a heat sink. The injection allocator control unit comprises an injection allocator shell, the heat sink and a chip; a groove is formed in the injection allocator shell; the heat sink is arranged in the groove; the chip is fixedly arranged on the heat sink; the heat sink comprises a heat sink shell; a water inlet and a water outlet are respectively formed in the front end and the rear end of the heat sink shell; parallel plates are evenly arranged in the heat sink shell in the front and rear direction; one end of each of the parallel plates is connected with a circular arc camber; each circular arc camber is tangential to one of the side walls in the left-right direction of the heat sink shell; the parallel plates, the circular arc cambers and the side walls of the heat sink shell form a Chinese character ji-shaped passage; two ends of the Chinese character ji-shaped passage are respectively communicated with the water inlet and the water outlet. According to the injection allocator control unit provided by the invention, turbulent flow cannot be generated in fluid, and an extremely thin thermal boundary layer can be generated on a bottom plate of the heat sink by the laminar flow of the fluid, so heat transferred by the chip is taken away better, the working temperature of the chip is lowered, and the reliability of the chip is enhanced.
Description
Technical field [0001] The invention relates to a petroleum refining device. Background technique [0002] With the ever-increasing demand for petroleum energy, oil reserves in oil fields are becoming less and less. In order to improve oil recovery, polymer flooding technology has become more and more popular in oil extraction. The key content of this polymer flooding oil recovery is the layered measurement and adjustment technology, which plays a huge role in improving oil recovery. [0003] In polymer injection well stratified oil recovery technology, eccentric injector is its key equipment, and its performance directly determines the effect of polymer flooding. The electronically controlled continuously adjustable eccentric dispenser, the control chip is designed in the dispenser, the chip is in a small enclosed space, continuous work will generate a lot of Joule heat, if too much heat can not be discharged, then the more The higher temperature will greatly reduce the service...
