液压油冷却器

性能要求:流量: 6L/min 进口油温: 85°C 出口油温: 50°C 空气温度: 45°C air flow: approx 1100m³/h oil Density @ 15°C: 0.92g/cm³ oil viscosity @ 40°C: 13,5mm²/s specific heat capacity: approx 1.7kJ/kg*K Dimensions: Width: 250mm Hight: 480mm Depth: 200mm。 Passenger: Hydraulic oil cooler performance requirements: flow: 6L / min inlet oil temperature: 85 ° C outlet oil temperature: 50 ° C air temperature: 45 ° C air flow: approx 1100m³ / h oil Density @ 15 ° C: 0.92g / cm³ oil viscosity @ 40 ° C: 13,5mm² / s specific heat capacity: approx. 1.7kJ / kg * K Dimensions: Width: 250mm Hight: 480mm Depth: 200mm.

Customer: Based on the above parameters, which cooler is more suitable?

Technique: Can't do 50 ℃. It is possible to achieve 45 + 10 = 55 ℃, which is safe.

Guest: In addition to the oil temperature cooling temperature can not reach, other parameters? Can accept 55 ℃ oil temperature.

Technique: To find out whether it is a DC or AC fan, I calculated that the core of the cooler can be sized according to the conditions. ...

Technique: The heat dissipation calculation manual is out and sent to the mailbox.

Customer: Is there a drawing for this?

Technology: No, it is only for heat dissipation calculation. The size of the radiator core has been determined. The installation space cannot meet customer requirements. There are two sizes exceeding: 250x200, because of the air volume of 1160m3 / h, at least ∮300 diameter fans are used.

Guest: For the cooler I talked about a few days ago, the customer said that they need 3 fans as shown above, DC 24V. The width of the cooler is 255mm.

Technology: Is 255 the maximum installation space size?

Guest: I will check and send you again later.

Passenger: width: 250, height: 480, thickness: 200. Final assembly dimensions.

Technique: OK, I will arrange the final assembly drawing in the past two days, and then let the relevant personnel quote you.

Customer: Taxes can be quoted as 1, 50, 1000. Our first year was 1,000 units and the second year was 2,000 units.

是立起来(480是高度)安装的吗? Technique: Oh, is the hydraulic oil cooler installed upright (480 height)?

Guest: Yes.

Technique: The drawings you show me are tube-fin type, large in volume and cooler than the plate-fin air-cooled equipment.

Customer: That's right, the effect is not ideal.
