Fig. 4 is the stereogram of expression fan-cover structure, and Fig. 5 is side view cutaway drawing.As shown in Figure 4 and Figure 5, fan guard 31 has the cylindrical portion 32 of containing box internal fan 26 and is integrally formed in flange part 33 and stator blade 34 on the cylindrical portion 32.
According to said structure, do not compare with the situation that does not form flexure planes 36 at four angles of the boundary part of flange part 33 and cylindrical portion 32, can increase the air quantity of the air in the suction fan cover 31.
By forming flexure plane 36 on four angles that are limited to flange part 33 and the boundary part of cylindrical portion 32, can reduce the width dimensions of flange part 33 on depth direction.So, just can fully guarantee the amount of taking in of container C and increase air quantity.
According to said structure, because case built-in motor 46 is configured in the Air blowing side of fan guard 31, separate and the corresponding gap of the axial length of case built-in motor 46 between the stator blade 34 that therefore can make fan guard 31 and the evaporimeter 25, thus can be from stator blade 34 to evaporimeter 25 wide scopes blow out air.
Particularly, if the air sucking side configuration case built-in motor 46 at fan guard 31, and the stator blade 34 of fan guard 31 is separated with evaporimeter 25, and the height dimension that then installs also can increase case built-in motor 46 except this spacing distance axial length is so large.
Relative therewith, in the present embodiment, can adopt the structure of the height dimension of restraining device, and can efficient well to evaporimeter 25 blow out air.And, by at Air blowing side configuration case built-in motor 46, namely can utilize the air that blows out that case built-in motor 46 is cooled off.
-running action-
Freezer for container 10 entry into service by making compressor 21, case external fan 24 and box fan 26 startings.In the refrigerant loop of freezer for container 10, the ejection cold-producing medium of compressor 21 is sent to condenser 23.Cold-producing medium at these condenser 23 internal circulations carries out heat exchange with the case outer air of being sent here by case external fan 24.As a result, cold-producing medium is condensed to the heat release of case outer air.
By the cold-producing medium of condenser 23 condensations after expansion valve is depressurized, be sent to again evaporimeter 25.Air carries out heat exchange in the cold-producing medium of the internal circulation of this evaporimeter 25 and the case of being sent here by box fan 26.As a result, cold-producing medium air heat absorption and evaporating in the case, air is cooled in the case.Should illustrate, as shown in Figure 2, air accommodation space S1 outside the upper side inflow case of division board 48 passes through evaporimeter 25 in the case.And air returns in the case from the downside of division board 48 after evaporimeter 25 is cooled in this case.After being inhaled in the compressor 21, the cold-producing medium of evaporimeter 25 evaporations again compressed.
Fig. 6 is the curve map of the relation of expression static pressure and air quantity, and Fig. 7 is the curve map of the relation of expression static pressure and input power.In Fig. 6 and Fig. 7, be illustrated in the curve map that is provided with the situation of flexure plane 36 on four angles of flange part 33 and the boundary part of cylindrical portion 32 with solid line, dot the curve map of the situation that flexure plane 36 is not set.Should illustrate, in the present embodiment, the radius of curvature of flexure plane 36 is 30mm, but is not limited to this.
Under the condition as shown in Figure 6: static pressure 70.6[Pa when freezer for container 10 normal operation], the situation that is provided with flexure plane 36 at flange part 33 and four angles of the boundary part of cylindrical portion 32 is compared the air quantity increase with the situation that flexure plane 36 is not set.
Under the condition as shown in Figure 7: static pressure 70.6[Pa when freezer for container 10 normal operation], the situation that is provided with flexure plane 36 at flange part 33 and four angles of the boundary part of cylindrical portion 32 is compared input power with the situation that flexure plane 36 is not set and is slightly reduced.
Hence one can see that: compare with the situation that flexure plane 36 is not set, be provided with in the situation of flexure plane 36 at four angles of flange part 33 with the boundary part of cylindrical portion 32, can increase air quantity in the situation that do not increase input power.
The effect of-present embodiment-
As mentioned above, the freezer for container 10 related according to present embodiment, because the opening of the air sucking side of fan guard 31 forms in the shape of flange part 33 with four angle expansions of the boundary part of cylindrical portion 32, therefore do not compare with forming flexure plane 36, can increase the air quantity that is inhaled into the air in the fan guard 31.And, by forming flexure plane 36 on four angles that are limited to flange part 33 and the boundary part of cylindrical portion 32, can reduce the width dimensions of flange part 33 on depth direction.So, just can fully guarantee the amount of taking in of container and increase air quantity.
-industrial applicability-
In sum, because in the freezer for container that the utility model cools off in to container, can obtain can increase air quantity in the situation that box fan is maximized, and can improve the very high effect of this practicality of heat exchanger effectiveness, therefore exceedingly useful and have a higher industrial applicability.
