Abstract
The utility model relates to a loader part, in particular to a hydraulic oil cylinder of a loader hydraulic system. The hydraulic oil cylinder is a loader hydraulic oil cylinder with a cooling device. The loader hydraulic oil cylinder comprises an oil cylinder body, wherein a cooling sheet is arranged on the side of the oil cylinder body and provided with fins; the fins and the cooling sheet are made of aluminum alloy and have an integrated structure; radiating pipes penetrate through the fins; and heat conduction liquid is closed in the radiating pipes. The hydraulic oil cylinder has the advantages that temperature can be effectively and quickly reduced, service life is prolonged, and performance is improved.
Description
Technical field
The utility model relates to the loader parts, particularly relates to the hydraulic jack of loader hydraulic system.
Background technique
The oil hydraulic cylinder inside of loader hydraulic system is hydraulic oil, and the place that hydraulic oil converges is provided with hydraulic jack, in the process of using; What hydraulic oil was frequent compressing into or extruding, and has higher temperature, influences the performance and the working life of hydraulic oil; In the prior art, hydraulic jack does not have cooling unit, can only lean on natural cooling; Rate of cooling is slow, has influenced its usability.
Summary of the invention
The purpose of the utility model is exactly to above-mentioned shortcoming, and a kind of effectively fast cooling is provided, and improves the loader hydraulic jack of performance---have the loader hydraulic jack of cooling unit.
The technological scheme of the utility model is achieved in that the loader hydraulic jack with cooling unit; Comprise the oil cylinder body; It is characterized in that: described oil cylinder body sidepiece is provided with cooling fin, and described cooling fin has fin, and fin and cooling fin are the integrative-structures that aluminum alloy is processed.
Say that further described fin inside is interspersed with heat dissipating pipe, airtight in the heat dissipating pipe have a heat transfer oil.
The beneficial effect of the utility model is: such oil hydraulic cylinder has effectively fast cooling, and then increases the service life, improves the advantage of performance.
Description of drawings
Fig. 1 is the cross section structure schematic representation of the oil hydraulic cylinder of the utility model loader hydraulic system.
Wherein: 1, cylinder body 2, cooling fin 3, fin 4, heat dissipating pipe.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
As shown in Figure 1: as to have the loader hydraulic jack of cooling unit, comprise oil cylinder body 1, it is characterized in that: described oil cylinder body 1 sidepiece is provided with cooling fin 2, and described cooling fin 2 has fin 3, and fin 3 is integrative-structures that aluminum alloy is processed with cooling fin 2.
Say that further described fin 3 inside are interspersed with heat dissipating pipe 4, airtight in the heat dissipating pipe 4 have a heat transfer oil.
Claims (2)
