3results about How to "Avoid affecting cooling efficiency" patented technology

The utility model provides a kind of dosing device for fouling marine organism prevention and treatment, dosing device includes medicine storage tank, first pipeline and dosing assembly, dosing assembly includes metering pump, safety valve and electric regulating valve, the medicine outlet of medicine storage tank is connected with first pipeline, second pipeline is installed on first pipeline, another end of second pipeline is installed with metering pump, the outlet of metering pump is connected with the import of electric regulating valve by third pipeline, the outlet of electric regulating valve is connected with dosing pipeline, third pipeline and first pipeline are communicated by fourth pipeline, safety pressure relief valve is installed on fourth pipeline.The dosing device can add antifouling marine organism's reagent to the seawater circulating system pipeline of power plant, nuclear power plant etc. using seawater as circulating cooling water, can effectively hinder marine organism to adhere in pipeline, avoid the insufficient supply of cooling water caused by the diameter reduction of seawater circulating system pipeline to affect cooling efficiency, and also can effectively avoid pipeline concrete deterioration and equipment corrosion.

The application discloses a kind of jet flow cold plate, machine case and electronic equipment, applied to heat dissipation field, jet flow cold plate includes: cold plate body is equipped with the cavity for placing fin component, inlet and outlet for cooling medium flow are equipped on cavity;Jet flow plate is installed in cavity, and cavity is divided into first cavity and second cavity, fin component is located inside second cavity, jet flow plate is equipped with several jet flow holes, to supply cooling medium jet flow from first cavity to second cavity;And, the included angle between the axial extension direction of jet flow hole and the surface of the bottom plate of fin component is acute angle.The jet flow cold plate provided in the application can effectively flush away the deposits between adjacent fins by forming a certain included angle between the jet flow hole and the bottom plate of the fin component, ensuring the smooth flow of the cooling medium and improving the heat dissipation reliability of the jet flow cold plate.

The utility model relates to machining center technical field especially relates to a kind of aluminium profile high-efficiency machining center based on multi-spindle structure, including machine body, the workbench is installed in machine body lower end, the four-axis tailstock is installed in workbench, the storage room is installed in machine body middle end, the discharge pipe for discharging cutting fluid is installed in storage room, auxiliary component for separating waste chip and cutting fluid and allowing cutting fluid to cool is provided in workbench.The waste chip and cutting fluid generated by the utility model cutting directly fall to workbench, and cutting fluid flows to communicating groove along inclined groove, due to the opening of inclined groove and communicating groove, increase cooling contact area, to improve the cooling efficiency of cutting fluid, and when cutting fluid flows to blocking inclined plate from communicating groove, to slow down the flow rate of cutting fluid, further improve the cooling efficiency of cutting fluid, until cutting fluid flows to collection box from discharge port to be collected, avoid the circulating use cutting fluid due to being in high temperature state, and affect the cooling efficiency.
