Quench tank cooler (heat exchanger)

　　 Quench tank cooler (heat exchanger) For oil cooling, there are tubular, plate, spiral plate, compound wave umbrella and air-cooled; for water cooling, there are tower.

　　Hot oil and cooling water staggered through adjacent channels, through the corrugated plate for heat exchange, forming a two-dimensional heat transfer surface exchanger, can be made into a large heat exchange surface.

　　2. In the tubular cooler, a plurality of small-diameter pure copper pipes or steel pipes are arranged in the steel cylindrical shell along the axial direction. Cooling water flows through the tubes and hot oil flows out of the tubes and is guided by baffles. Tortuous flow, tubular oil cooler, GLC series, GLL series, GLL-I series, series (vertical), applicable medium for N10 ~ N460 industrial lubricating oil, temperature not higher than 100 ℃, cooling water temperature not higher than 30 ℃. GLC series. Especially suitable for small flow cooling.

　　3. Spiral plate cooler, its structure is made of two parallel steel plates rolled to form a channel, and the two media flow in reverse in their respective channels. The heat exchange circuit is long and has a high heat exchange coefficient.

　　4. compound wave umbrella cooler, its plates are made of 1Cr18Ni9Ti steel plate, and the heat exchange coefficient of the cooler is 348W/(m2 & middot;℃), the cooling effect is general and the price is relatively high.

　　5. Air-cooled cooler, which is composed of fin tubes composed of heat exchange fin tube bundles and axial fan. The oil flowing in the tube is cooled by forced ventilation with a fan. The finned tubes can be made of aluminum, copper, steel or stainless steel and brazed or rolled to expand the tube to connect the sub-manifold. Air flows through the fin tube by a fan blast or suction. It should be used where there is a lack of cooling water source or where the ambient air temperature is at least 6~10 ℃ lower than the oil temperature. This has the advantage that the possibility of oil leakage 1 water is eliminated. The disadvantage is that the fan noise is large, the oil pump (such as gear pump) with large head is required, and the cost is high. The heat exchange coefficient of this cooler is 46W/(m2 & middot;℃).
