5. comparative example
Fig. 5 is the sectional view of the power house of comparative example, and Fig. 6 is the stereogram of the heat exchanger assemblies of comparative example, Fig. 5 and figure
6 correspond respectively to Fig. 2 and Fig. 3.As shown in figure 5, in the comparative example, the interval of first heat exchanger a and second heat exchanger b
G ratios b is small.In addition, as shown in fig. 6, the component for the guide member 53 not being equivalent in present embodiment, second heat exchanger
B is supported by bearing part c by first heat exchanger a.
At this point, when generating cooling wind in power house, in the hydraulic excavator often run under the more environment of dust
In the case of, due to being not intended to suck extraneous air from dusty earth's surface surface side, air entry d, e are generally located on dynamic
The top of power room.Moreover, in order to inhibit dust to flow into power house, air entry d, e will not be open too big.In addition, in order to discharge from
In the issuable gases of battery f of bottom setting, the left room of power house needs bigger front space g.Therefore, compared under
Wind speed is relatively slow in portion region and is easy disorderly situation, and the flowing of the cooling wind in the front space g with corresponding volume is being inhaled
Nearby wind speed is significantly faster by gas port d, e.
In a comparative example, due to not being equivalent to the component of guide member 53, as shown in figure 5, relative to heat exchange
The wind speed profile of the interarea of device assembly is uneven.Further, due to first heat exchanger a and second heat exchanger b interval g compared with
It is narrow, therefore back side of the cooling wind around the interarea of second heat exchanger b is hindered, cooling wind is difficult to contact first heat exchanger
The part opposite with second heat exchanger b in a interareas.Inventor hereins are based on the studies above, have rediscovered
There is a possibility that the cooling performance for being unable to give full play heat exchanger assemblies in the structure of analog example.
6. effect
(1) raising of cooling efficiency
When increasing the interval G of second heat exchanger 52 and first heat exchanger 51, second heat exchanger 52 is got over from fan 2
Far, the wind speed of the cooling wind 20 of contact second heat exchanger 52 is slower, but in the present embodiment by the way that guide member 53 is arranged,
The flowing of the cooling wind 20 in front space 17 is carried out in its inlet portion 53a to enable its flow into guide member 53 after throttling speedup.
At this point, inlet portion 53a position and size according to second heat exchanger 52 set, therefore the cooling wind 20 of speedup uniformly in contact with
The interarea of second heat exchanger 52 can effectively play the heat exchange performance of condenser 7 and fuel cooler 8, improve cooling
Efficiency.
Cooling wind 20 by second heat exchanger 52 is directed into the expansion section 53c of guide member 53, increases bore
The entirety of the interarea of contact first heat exchanger 51 afterwards.At this point, due between second heat exchanger 52 and first heat exchanger 51
The interval G separated is bigger than the thickness T1 of first heat exchanger 51, and enough spaces are ensured in the behind of second heat exchanger 52,
Therefore the cooling wind 20 after cooling second heat exchanger 52 can be such that cooling wind 20 has around the back side of second heat exchanger 52
The part opposite with second heat exchanger 52 in the interarea of effect ground contact first heat exchanger 51.Cooling wind 20 can as a result,
Uniformly in contact with the interarea of first heat exchanger 51, the heat exchange of charge air cooler 4, radiator 5 and oil cooler 6 is effectively played
Can, cooling efficiency can be improved.
(2) the manufacture simplification of heat exchanger assemblies
In the comparative example using first heat exchanger a bearing second heat exchangers b, in order to increase first heat exchanger a
Interval g between second heat exchanger b, it is necessary to extend bearing part c.In turn, if it is considered that ensure defined rigidity,
The width and thickness of bearing part c also have to then be increased, it is difficult to expand interval g.Unlike this, pass through in the present embodiment
Second heat exchanger 52 is supported using guide member 53, bearing part 18 can not be made, which to be easily manufactured enlargedly, ensures first
The heat exchanger assemblies 50 larger with the interval G of second heat exchanger 52 of heat exchanger 51.Guide member 53 itself can also lead to
It crosses and is easily and inexpensively manufactured by junction steel plates such as welding.
(3) inhibit the enlargement of heat exchanger assemblies
When the interval G deficiencies of second heat exchanger 52 and first heat exchanger 51, cooling wind 20 can not be around the second heat
The back side of exchanger 52, but inside narrow power house 115, interval G can be restricted.According to emulation as a result, it has been found that：
When increasing interval G, from three times of thickness T1 of first heat exchanger 51 or so, cooling wind 20 increases around effect.Separately
On the one hand, under the restriction of the interior layout of power house 115, seven times or so of T are the upper limits for the interval G that can ensure that.Therefore, lead to
The degree as 3 × T1≤G≤7 × T1 is crossed, the raising of heat exchange performance can be taken into account and inhibits the big of heat exchanger assemblies 50
The effect of type.
(4) other
If guide member 53 is made to be outer edge from inlet portion 53a to outlet side, flow path is in a linearly widened shape
The ratio of shape, the then cooling wind 20 that 53c is directed to lower section along expansion section is excessively increased, and may be decreased the wind of first heat exchanger 51
The uniformity of speed distribution.Unlike this, use in the present embodiment with expansion section 53c be boundary, so that guide member 53 is had
The structure of step difference, therefore the excessive guiding of cooling wind 20 can be inhibited, it can aid in the uniformity for improving wind speed profile.This
Outside, it due to the stage portion of the amount of the size T2 generated there are expansion section 53c, can avoid occurring with the installation space of battery 16 dry
It relates to, it can be ensured that battery 16 is easy to be laid out.
In addition, in present embodiment, it is induction type to make the position relationship of heat exchanger assemblies 50 and fan 2, thus with adopt
It is compared with the case where type air blast (forced ventilation) fan, makes the uniform aspect of wind speed profile advantageously.
