Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.
Shown in Fig. 1 and Fig. 2, according to embodiments of the invention, cylinder block comprises cylinder head, and cylinder head is provided with cylinder-bore 1, interval trough 2 and screw mounting hole 4, interval trough 2 is positioned in the cylinder head plane 3 of cylinder block, and between cylinder-bore 1 and screw mounting hole 4.
Interval trough 2 is arranged between cylinder-bore 1 and screw mounting hole 4, the heat-dissipating distance of the high-temperature gas in cylinder-bore 1 is shortened, can dispel the heat, accelerate the radiating efficiency of high-temperature gas in cylinder-bore 1, improve the radiating effect of cylinder block from interval trough 2.In compressor operation, the lubricant oil that oil outlet on crankshaft crank throws away can be splashed in interval trough 2, and flow in interval trough 2, thus take away heat unnecessary in cylinder, reduce sucking the heating of refrigeration agent and reducing the temperature of swell refrigeration agent, thus improve the heat dispersion of cylinder block further.Screw mounting hole 4 and cylinder-bore 1 structure can be separated by interval trough 2, make when being fixed on cylinder head by the screw of cylinder head, can not produce distortion, ensure that the circularity of cylinder-bore 1 to cylinder-bore 1, avoid piston and the stuck situation of cylinder-bore 1.
Interval trough 2 winding in cylinder-bore 1 periphery, can and cylinder-bore 1 between circumferentially there is good heat transfer effect, thus ensure radiating effect to the high-temperature gas in cylinder-bore 1.
In conjunction with shown in Figure 1, in the present embodiment, interval trough 2 extends to the opposite side relative with this side from the side of cylinder head plane 3, ensure that lubricant oil can flow to opposite side from the side of cylinder head plane 3, and in the process of flowing, take away the heat of the high-temperature gas in cylinder-bore 1, thus reduce sucking the heating of refrigeration agent and reducing the temperature of swell refrigeration agent.
Specifically, in the present embodiment, it is symmetrical along the central plane of cylinder-bore 1 that interval trough 2 comprises the first groove 5 and the second groove 6, first groove 5 and the second groove 6, and the first groove 5 all extends to the opposite side relative with this side from the side of cylinder head plane 3 with the second groove 6.First groove 5 and the second groove 6 dispel the heat to the high-temperature gas in cylinder-bore 1 from the both sides of cylinder-bore 1 simultaneously, can accelerate the efficiency that interval trough 2 takes away the high-temperature gas heat in cylinder-bore 1, improve the integral heat sink effect of cylinder block.In addition, the first groove 5 and the second groove 6 are symmetrical arranged, and the heat transmission in interval trough 2 pairs of cylinder-bore 1 also can be made more even, ensure the uniform heat distribution of the high-temperature gas in cylinder-bore 1.
The minimum separable of the first groove 5 and the second groove 6 is positioned at the edge of cylinder head plane 3, and the minimum separable of the first groove 5 and the second groove 6 is between 8 to 20mm, both avoided the first groove 5 and the second groove 6 hypotelorism and affected the structural strength of cylinder head, also having avoided the first groove 5 and the second groove 6 hypertelorism and the radiating effect affected the high-temperature gas in cylinder-bore 1.
In one drawing in unshowned embodiment, the import of interval trough 2 and opening are positioned at the same side of cylinder head plane 3, after lubricant oil enters interval trough 2, from inlet around cylinder-bore 1 week, then flow out from opening, in the process of flowing, take away the heat of the high-temperature gas in cylinder-bore 1.
Interval trough 2 comprises winding at the medial arc section 7 of cylinder-bore 1 periphery and the edge arcuate segment 8 being positioned at medial arc section 7 two ends, and edge arcuate segment 8 extends to the edge of cylinder head plane 3.Medial arc section 7 is concentric with cylinder-bore 1, and the minimum separable between the inwall of the madial wall of interval trough 2 and cylinder-bore 1 is between 3 to 7mm.Medial arc section 7 is concentric with cylinder-bore 1, can ensure that medial arc section 7 can take away the heat of the high-temperature gas in cylinder-bore 1 more equably.Minimum separable between the madial wall of interval trough 2 and the inwall of cylinder-bore 1, between 3 to 7mm, can ensure that interval trough 2 can the radiating efficiency of larger raising cylinder-bore 1, can not affect the structure stability of cylinder-bore 1 simultaneously.
The width of interval trough 2 is 2 to 5mm, can ensure that interval trough 2 has enough spacing and holds enough lubricant oil, thus make lubricant oil efficient can take away more greatly heat in cylinder-bore 1 in flow process, simultaneously interval trough 2 also can be avoided wide and cause lubricant oil cannot in interval trough 2 smooth outflow, affect the mobility of lubricant oil, and then affect the efficiency that the heat in cylinder-bore 1 taken away by lubricant oil.
Preferably, the degree of depth of interval trough 2 is less than or equal to the half of cylinder-bore 1 degree of depth, and the lubricant oil in guarantee interval trough 2 to the heat diffusion area of the inwall of cylinder-bore 1, thus improves the heat dispersion of cylinder block.
According to embodiments of the invention, piston compressor comprises cylinder block, and this piston compressor is above-mentioned piston compressor.
Certainly, be more than the preferred embodiment of the present invention.It should be pointed out that for those skilled in the art, under the prerequisite not departing from its general principles, can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
