Technical problem to be solved by the invention
In the cooling device proposed in patent document 1, since the condenser is disposed in a horizontal posture in an upper region of the evaporation unit, it is necessary to secure a sufficient size in the front-rear direction as a space for disposing the condenser. Therefore, the size in the front-rear direction becomes large, resulting in an increase in the size of the entire apparatus.
The present invention has been made in view of the above circumstances, and an object thereof is to provide a cooling device that can achieve a reduction in size of the entire device.
Technical scheme for solving technical problem
In order to achieve the above object, a cooling device of the present invention includes: a cooling unit including an evaporator that evaporates a supplied refrigerant to cool a fluid passing through the periphery, a compressor that sucks and compresses the refrigerant evaporated by the evaporator, and a condenser that condenses the refrigerant compressed by the compressor; and an evaporation unit having an evaporation pan for storing dew condensation water generated by the cooling unit and an evaporation/absorption material standing on the evaporation pan and absorbing the dew condensation water by capillary action, wherein the condenser is provided in a standing posture in which a length in a front-rear direction is shorter than a horizontal posture, the evaporation/absorption material standing on a rear side of the condenser, and the cooling unit includes an air blowing fan horizontally provided to close an upper opening of an air tunnel provided on the rear side of the evaporation/absorption material and blowing air so that the air having passed through the condenser passes through the evaporation/absorption material, passes through an inside of the air tunnel, and is sent upward from the upper opening.
In the cooling device of the present invention, the evaporation/absorption material is configured such that a corrugated wave-shaped sheet member is interposed between flat plate-shaped sheet members spaced apart in parallel to each other when viewed from the front.
In the cooling device of the present invention, the plurality of air blowing fans are arranged side by side in the left-right direction, and the air tunnel includes wall members provided apart from each other in the left-right direction in correspondence with the air blowing fans.
Effects of the invention
According to the present invention, since the condenser is provided in a standing posture in which the length in the front-rear direction is shorter than that in a horizontal posture, and the blower fan blows air so that the air having passed through the condenser passes through the evaporation absorption material, passes through the interior of the air tunnel, and is sent upward from the upper opening, the blower fan is horizontally provided so as to close the upper opening of the air tunnel provided on the rear side of the evaporation absorption material standing on the rear side of the condenser, the size in the front-rear direction can be reduced as compared with the case where the condenser is provided in a horizontal posture as in the related art, and the entire device can be downsized. Further, since the air passing through the condenser from the front to the rear is sent out upward from the upper surface opening of the wind tunnel by the air sending fan, there is an effect that the air sent out from the upper surface opening can be suppressed from passing through the condenser by the action of the air sending fan.

Hereinafter, preferred embodiments of the cooling device of the present invention will be described in detail with reference to the drawings.
Fig. 1 is a sectional side view schematically showing the internal structure of a display case to which a cooling apparatus according to an embodiment of the present invention is applied. The display case illustrated herein includes a case main body 10.
The case main body 10 is a heat insulating case having an opening (hereinafter, also referred to as a front surface opening) 10a on a front surface. The housing main body 10 defines a storage chamber 11 therein, and is provided with an air circulation device 20 and a cooling device 30.
The storage chamber 11 is a chamber defined to face the front opening 10a, and a plurality of (five in the illustrated example) commodity racks 12 are arranged in a vertical direction. The commodity shelf 12 is a member for placing commodities, respectively.
A bottom tray 13 is provided at the bottom of the storage chamber 11. The bottom tray 13 is a member for placing commodities, as in the commodity rack 12.
Further, a suction port 14 is formed at a front lower portion of the storage chamber 11, and a discharge port 15 is formed at a front upper portion of the storage chamber 11.
The suction port 14 is an opening for sucking air inside the storage chamber 11, and extends in the left-right direction of the storage chamber 11. The air outlet 15 is an opening for blowing air into the storage chamber 11. The air outlet 15 extends in the left-right direction of the storage chamber 11. Although not clearly shown in the drawings, a flow rectification member having a honeycomb structure is appropriately attached to the air outlet 15.
The air circulation device 20 includes an air passage 20a and a circulation fan 20 b. Air flow path 20a is a flow path of air from suction port 14 to discharge port 15.
The air flow path 20a is configured to communicate with each other: a lower air passage 21 communicating with the suction port 14 and located outside the storage compartment 11 and below the storage compartment 11; a back-side air duct 22, the back-side air duct 22 being located outside the storage compartment 11 and on the back side of the storage compartment 11; a storage box 23, the storage box 23 being located outside the storage chamber 11 and above the storage chamber 11; and an upper air flow path 24, the upper air flow path 24 being located outside the storage compartment 11 and above the storage compartment 11 and communicating with the air outlet 15.
The circulation fan 20b is a member that circulates air by being driven, and is provided at a predetermined position in the lower air passage 21. In the present embodiment, the circulation fan 20b is provided at a predetermined position in the lower air flow passage 21, but in the present invention, the position at which the circulation fan 20b is disposed is not particularly limited, and may be provided at any position as long as the function of the circulation fan 20b described below can be exerted.
In the air circulation device 20, the air inside the storage chamber 11 is sucked through the suction port 14 by driving the circulation fan 20b, the sucked air is sent out to the air outlet 15 so as to pass through the air flow path 20a, and the air is blown out into the storage chamber 11 through the air outlet 15, thereby circulating the air between the inside and the outside of the storage chamber 11.
Fig. 2 is a perspective view showing cooling device 30 shown in fig. 1. As also shown in fig. 2 above, the cooling device 30 includes a cooling unit 30a and an evaporation unit 30 b.
The cooling unit 30a is configured by connecting an evaporator 31, a compressor 32, a condenser 33, and an expansion mechanism 34 in this order by a refrigerant line 35. The evaporator 31 is provided inside the storage box 23, and cools air passing through the inside of the storage box 23 by evaporating the supplied refrigerant. The refrigerant evaporated by the evaporator 31 is sucked and compressed by driving the compressor 32.
The condenser 33 is provided in a standing posture in front of the top wall portion of the main cabinet. As shown in fig. 3, in the condenser 33, flat refrigerant passage tubes 33a in which a plurality of refrigerant passages are arranged in parallel are provided so as to extend in the vertical direction while meandering in the horizontal direction, an inlet-side header 33b is connected to the inlet side of the refrigerant passage tubes 33a, and an outlet-side header 33c is connected to the outlet side of the refrigerant passage tubes 33 a. Corrugated fin members 33d are thermally connected between horizontally extending portions of the refrigerant passage tubes 33 a. A refrigerant line 35 connected to the outlet side of the compressor 32 is connected to the inlet-side header 33b, and a refrigerant line 35 connected to the expansion mechanism 34 is connected to the outlet-side header 33 c. The condenser 33 causes heat exchange between the refrigerant compressed by the compressor 32 and passing through the refrigerant flow path and the air passing through the surroundings, thereby condensing the refrigerant.
That is, the condenser 33 can be installed in a standing posture in which the refrigerant compressed by the compressor 32 flows in the vertical direction while meandering in the left-right direction, and in a shorter length in the front-rear direction than in a lying posture in which the refrigerant compressed by the compressor 32 flows in the front-rear direction while meandering in the left-right direction.
The expansion mechanism 34 adiabatically expands the refrigerant condensed by the condenser 33 to a low-temperature and low-pressure state, and supplies the refrigerant to the evaporator 31.
As shown in fig. 4, the evaporation unit 30b is provided on the rear side of the condenser 33 and on the front side of the storage box 23, and includes an evaporation pan 36 and an evaporation/absorption material 37.
The evaporation pan 36 is a member for storing dew condensation water generated by the cooling unit 30a (evaporator 31) by a not-shown tank.
The evaporation/absorption material 37 is provided in plural (two in the illustrated example) and has a rectangular shape. The evaporation absorbing materials 37 are erected on the evaporation pan 36 at the rear side of the condenser 33 so as to be arranged in the left-right direction. The evaporation/absorption material 37 is formed by processing filter paper, and more specifically, as shown in fig. 5, a corrugated sheet member 372 having a corrugated shape is sandwiched between flat plate-shaped flat sheet members 371 that are separated in the left-right direction so as to be parallel to each other when viewed from the front. The evaporation/absorption material 37 absorbs the dew condensation water stored in the evaporation pan 36 by capillary action so that the dew condensation water is absorbed by the flat sheet member 371 and dispersed to the corrugated sheet member 372.
An air tunnel 40 is provided in the region above the evaporation pan 36 and behind the evaporation/absorption member 37. As shown in fig. 6, the wind tunnel 40 includes: a pair of left and right side walls 41; a rear wall 42 connecting rear ends of the side walls 41 to each other; an upper wall 43 connecting upper ends of the side walls 41 to each other and also connecting an upper end of the rear wall 42; and a base wall 44 disposed opposite the upper wall 43. That is, the wind tunnel 40 has a rectangular shape with an open front surface. The front end portion of the side wall 41 extends forward beyond the upper wall 43 and the base wall 44, and covers both side regions of the evaporation/absorption material 37.
A rectangular upper opening 43a is formed over substantially the entire area of the upper wall 43 of the wind tunnel 40, and a plurality of (four in the illustrated example) air blowing fans 45 are horizontally arranged in the left-right direction so as to close the upper opening 43 a. The blower fan 45 sends out the air passing through the air tunnel 40 toward the upper side of the upper opening 43a when driven. In the present embodiment, the air blowing amount of the two blower fans 45 on the center side is adjusted to be larger than the air blowing amount of the blower fans 45 on the left and right sides.
A plurality of (three in the illustrated example) wall members 46 are provided on the base wall 44 of the wind tunnel 40. The wall members 46 are provided on the base wall 44 so as to be spaced apart from each other in the left-right direction so as to extend upward from portions facing portions between the adjacent air blowing fans 45. That is, the wall members 46 are provided apart from each other in the left-right direction corresponding to the blower fan 45.
In the display case configured as described above, the circulation fan 20b is driven to suck air in the storage compartment 11 through the suction port 14, and the air passes through the lower air passage 21 and the rear air passage 22 and enters the storage box 23. The air that has entered the storage box 23 passes through the upper air passage 24, reaches the air outlet 15, and is blown out from the air outlet 15. The air blown out from the air outlet 15 flows toward the air inlet 14 while passing through the front end of each of the commodity racks 12, thereby forming an air curtain.
In the cooling device 30, the compressor 32 is driven, whereby the refrigerant compressed by the compressor 32 is condensed by the condenser 33 and reaches the expansion mechanism 34. The refrigerant sent to the expansion mechanism 34 is sent to the evaporator 31 while being thermally insulated and expanded, and exchanges heat with the air passing through the housing box 23 and evaporates when passing through the refrigerant flow path of the evaporator 31. The evaporated refrigerant is drawn by the compressor 32 to circulate.
By driving the compressor 32 in this manner to cool the air passing through the storage box 23, the cooled air is blown out from the air outlet 15, and as a result, the internal air of the storage chamber 11 is cooled and the commodities mounted on the commodity mounting rack 12 are cooled.
Further, dew condensation water is generated in the evaporator 31 by driving the compressor 32, and the generated dew condensation water is supplied to the evaporation pan 36 through the groove and stored in the evaporation pan 36.
In the cooling device 30, the blower fan 45 is driven to cause the air outside the casing body 10 to pass through the condenser 33 from the front to the rear, and then to pass through the evaporation/absorption material 37. Thus, the air having passed through the evaporation/absorption member 37 reaches the inside of the air tunnel 40, passes through between the side wall 41 and the wall member 46, or passes through between the wall members 46, and is sent out to the upper side of the upper opening 43 a.
As described above, according to the cooling device 30 of the embodiment of the present invention, the condenser 33 is provided in the standing posture in which the length in the front-rear direction is shorter than that in the horizontal posture, the blower fan 45 blows air so that the air having passed through the condenser 33 passes through the evaporation absorbing material 37, passes through the inside of the air tunnel 40, and is sent upward from the upper opening 43a, the blower fan 45 is horizontally provided so as to close the upper opening 43a of the air tunnel 40, and the air tunnel 40 is provided on the rear side of the condenser 33 and stands behind the evaporation absorbing material 37 of the evaporation pan 36, so that the size in the front-rear direction can be reduced as compared with the conventional condenser provided in the horizontal posture, and the entire device can be downsized. Further, since the air blower fan 45 sends out the air having passed through the condenser 33 from the front to the rear, toward the upper side of the upper opening 43a of the wind tunnel 40, the air sent out from the upper opening 43a can be prevented from passing through the condenser 33 by the action of the air blower fan 45.
According to the cooling device 30, since the evaporation/absorption member 37 is configured such that the corrugated sheet member 372 is sandwiched between the flat plate-shaped flat sheet members 371 which are spaced apart in the left-right direction so as to be parallel to each other when viewed from the front, the contact area with the air blown by the air blowing fan 45 can be increased, and the air blowing amount can be sufficiently secured by passing the air through the gap between the flat sheet member 371 and the corrugated sheet member 372. Therefore, dew condensation water can be evaporated well. Since the air passing through the evaporation/absorption material 37 is the air passing through the condenser 33, the air having a temperature increased by the condenser 33 and a relative humidity decreased passes through the evaporation/absorption material 37, and the dew condensation water can be evaporated well.
According to the cooling device 30, since the wall members 46 are provided on the base wall 44 constituting the air tunnel 40 so as to be spaced apart from each other in the left-right direction in correspondence with the air blowing fans 45, the air in the air tunnel 40 is caused to pass between the side walls 41 and the wall members 46 or between the wall members 46 by driving the air blowing fans 45, and the wall members 46 function as flow regulating members for guiding the air, whereby occurrence of turbulence caused by interference between the air passing by driving the air blowing fans 45 can be suppressed.
According to the cooling device 30, since the air blowing amounts of the two blower fans 45 on the center side are adjusted to be larger than the air blowing amounts of the blower fans 45 on the left and right sides, the air that has passed through the evaporation and absorption material 37 and reached the inside of the wind tunnel 40 can be blown well.
While the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications can be made.
Although in the above-described embodiment, the evaporation absorbing material 37 is configured such that the corrugated wave-shaped sheet member 372 is sandwiched between the flat plate-shaped flat sheet members 371 that are separated in the left-right direction so as to be parallel to each other, in the present invention, as shown in fig. 7, the evaporation absorbing material 37 ' may be configured such that the corrugated wave-shaped sheet member 372 ' is sandwiched between the flat plate-shaped flat sheet members 371 ' that are separated in the up-down direction so as to be parallel to each other when viewed from the front. Thus, the evaporation/absorption material 37 ' can absorb dew condensation water by capillary action, and the amount of air blown can be sufficiently ensured by passing air through the gap between the flat sheet member 371 ' and the corrugated sheet member 372 '.
In the above embodiment, the cooling device 30 applied to the showcase has been described, but the present invention is not limited to the showcase and may be applied to a vending machine or the like.
In the above embodiment, the evaporation/absorption material 37 is configured such that the corrugated wave-shaped sheet member 372 is sandwiched between the flat plate-shaped sheet members 371 which are spaced apart in the vertical direction so as to be parallel to each other when viewed from the front.
