5. comparative example
Fig. 5 is the sectional view of the power house of comparative example, and Fig. 6 is the heat exchanger assemblies of comparative example
Axonometric chart, Fig. 5 and Fig. 6 corresponds respectively to Fig. 2 and Fig. 3.As it is shown in figure 5, compare at this
In example, the interval g of the first heat exchanger a and the second heat exchanger b is less than b.Additionally, such as
Shown in Fig. 6, be not equivalent to the parts of guide member 53 in present embodiment, the second heat
Exchanger b is supported by the first heat exchanger a by supporting parts c.
Now, when producing cooling wind in power house, often transporting in the environment of dust is more
In the case of the hydraulic excavator of row, owing to being not intended to from the ground surface side stirred up a cloud of dust sucks
Portion's air, therefore air entry d, e is generally located on the top of power house.And, in order to suppress
Dust flow into power house, air entry d, e will not opening the biggest.Additionally, in order to discharge from the end of at
The issuable gas of battery f that portion is arranged, the left room of power house needs bigger front space g.
Therefore, compared to the situation that wind speed in lower area is relatively slow and the most disorderly, there is corresponding appearance
Near air entry d, e, wind speed is the most faster in the flowing of the cooling wind in long-pending front space g.
In a comparative example, owing to not being equivalent to the parts of guide member 53, therefore such as Fig. 5 institute
Show, uneven relative to the wind speed profile of the interarea of heat exchanger assemblies.Further, due to
The interval g of one heat exchanger a and the second heat exchanger b is narrower, therefore hinder cooling wind around
To the rear side of the interarea of the second heat exchanger b, cooling wind is difficult to contact the first heat exchanger a
The part relative for heat exchanger b with second in interarea.Inventor herein are based on above-mentioned
Research, has rediscovered existence in the structure of analog example and cannot give full play to heat exchanger
The probability of the cooling performance of assembly.
6. effect
(1) raising of cooling effectiveness
When increasing the interval G of the second heat exchanger 52 and the first heat exchanger 51, the second heat
Exchanger 52 from fan 2 more away from, contact the wind speed of cooling wind 20 of the second heat exchanger 52 more
Slowly, but in the present embodiment by arranging guide member 53, at its inlet portion 53a to front sky
Between the flowing of cooling wind 20 in 17 carry out throttling and enable its flow into guide member 53 after speedup.
Now, position and the size of inlet portion 53a set according to the second heat exchanger 52, therefore speedup
Cooling wind 20 uniformly in contact with the interarea of the second heat exchanger 52, it is possible to effectively play cold
Condenser 7 and the heat exchange performance of fuel cooler 8, improve cooling effectiveness.
Cooling wind 20 through the second heat exchanger 52 is directed into the expansion section of guide member 53
53c, contacts the entirety of the interarea of the first heat exchanger 51 after increasing bore.Now, due to
The spaced apart interval G of the second heat exchanger 52 and the first heat exchanger 51 is than the first heat exchange
The thickness T1 of device 51 is big, ensure that enough spaces in the behind of the second heat exchanger 52, because of
This cools down the rear side around the second heat exchanger 52 of the cooling wind 20 after the second heat exchanger 52,
Cooling wind 20 can be made effectively to contact handing over the second heat in the interarea of the first heat exchanger 51
The part that parallel operation 52 is relative.Thus, cooling wind 20 can be uniformly in contact with the first heat exchanger
The interarea of 51, plays charge air cooler 4, radiator 5 and the heat exchange of oil cooler 6 effectively
Can, it is possible to increase cooling effectiveness.
(2) the manufacture simplification of heat exchanger assemblies
Support in the comparative example of the second heat exchanger b, in order to increase utilizing the first heat exchanger a
Interval g between big first heat exchanger a and the second heat exchanger b, it is necessary to extend supporting parts
c.And then, if it is considered that to guarantee the rigidity of regulation, then also have to increase supporting parts c
Width and thickness, it is difficult to expand interval g.Unlike this, in the present embodiment by utilizing
Guide member 53 supports the second heat exchanger 52, it is possible to do not make supporting parts 18 hold with maximizing
Change places and manufacture the heat bigger for interval G guaranteeing the first heat exchanger 51 and the second heat exchanger 52
Exchanger assembly 50.Guide member 53 self also is able to by being come easily by junction steel plates such as welding
And be manufactured inexpensively.
(3) maximization of heat exchanger assemblies is suppressed
When the interval G deficiency of the second heat exchanger 52 and the first heat exchanger 51, cool down wind
20 cannot be around the rear side of the second heat exchanger 52, but inside narrow power house 115,
Interval G can be restricted.According to emulation found that: when increase interval G time, from first
About three times of the thickness T1 of heat exchanger 51 are risen, and the effect of walking around of cooling wind 20 increases.Separately
On the one hand, under the restriction of the interior layout of power house 115, about seven times of T can ensure that
The upper limit of interval G.Therefore, by becoming the degree of 3 × T1≤G≤7 × T1, it is possible to take into account
The raising of heat exchange performance and the effect of the maximization of suppression heat exchanger assemblies 50.
(4) other
If making guide member 53 is the outer edge from inlet portion 53a to outlet side, stream is one
The shape expanded point-blank, then be directed to the ratio mistake of the cooling wind 20 of lower section along expansion section 53c
Degree increases, and may reduce the uniformity of the wind speed profile of the first heat exchanger 51.Unlike this,
Use in the present embodiment and be boundary with expansion section 53c, make guide member 53 have step difference
Structure, therefore, it is possible to the excessive guiding of suppression cooling wind 20, it is possible to be favorably improved wind speed and divide
The uniformity of cloth.Additionally, due to there is the stage portion of the amount of size T2 that expansion section 53c produces,
It can be avoided that interfere with the installation space of battery 16, it can be ensured that battery 16 is prone to layout.
Additionally, in present embodiment, the heat exchanger assemblies 50 is made with the position relationship of fan 2 to be
Induction type, therefore compared with the situation using type air blast (forced ventilation) fan, makes wind speed
The aspect being evenly distributed is advantageously.
