Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a regenerative cooler box, which is mainly used for bed room cooling provided in a cabin of a long-distance truck, and can be used as outdoor equipment.

[0002]

[Prior art]

 As shown in FIGS. 6, 7 and 8, when the bed room 1 provided in the cabin of a long-distance truck is used for a nap in the summer, an existing car for cooling the cabin during traveling is used. The cooler (front air conditioner) 2 is turned on and the cool storage switch is turned on, and the refrigerant is intermittently opened and closed by the two solenoid valves 3a and 3b, so that the refrigerant flows into the car cooler 2 and the bed cooler-4. The bed is alternately flown to the side, cooling the inside of the cabin, freezing the cold storage material 5 on the bed-muku-ra-4 side, and providing the bed in the bed-muku-ra-4 with the engine stopped. By operating the fan 6, the air in the bed room 1 sucked through the suction port 7 is passed directly between the cold storage materials 5 to be cooled, and is blown from the outlet 8 into the bed room 1 for cooling. The existing car cooler-2 comprises a compressor 9, an evaporator 10, a condenser 11, a receiver 12, a constant pressure expansion valve 13 and the like.

[0003]

[Problems to be solved by the invention]

 In the prior art, the bed cooler 4 is connected to the existing car cooler 2 and the coolant is intermittently and alternately flowed to both sides to cool the cold storage material 5, so that the solenoid valves 3a, 3b, Improvement work for attaching the constant pressure expansion valve 13 and piping work for connecting the car cooler 2 and the bed muller 4 are required. The cooling efficiency is poor because air is directly blown for cooling, and high-humidity cool air is blown into the bed room.

[0004]

[Means for Solving the Problems] The housing is divided into a vertical upper chamber and a lower chamber, and a cold air discharge part of a heat pipe type heat exchanger (super heat conduction pipe) is arranged in a row facing the lower chamber. In addition, cooling fins are provided over the cool air discharge portion, a blower fan and a cool air blowout louver are provided, and the cool air absorbing portion of the heat pipe type heat exchanger is arranged in line with the upper chamber. A cool storage material (cool storage pack) is inserted between the cold air absorbing parts. The cool storage material is kept cool while the truck is running, and when the truck is stopped (when the engine is stopped) and where there is no commercial power supply, the on-board battery or Power is supplied to the blower fan in the lower chamber by blowing air at room temperature to the cold air discharge section of the heat pipe type heat exchanger, and the working fluid sealed in the heat pipe type heat exchanger is discharged. When evaporating, it absorbs latent heat of evaporation, and the upper chamber The heat moves at a high speed to the cold air absorbing section (low temperature section) where the cold air has been absorbed by the latent heat of fusion of the cold storage material. At this time, the working steam is condensed, the latent heat of evaporation is released, and the cooled working fluid is cooled. The cool air that returns to the cool air discharge section due to the phenomenon and exchanges heat in the cool air absorbing section is blown out from the cool air blowout louver into the truck bed room by the blower fan, and is cooled by repeating this cooling circulation cycle. Low battery power required only for the blower fan, which does not have to worry about going up, quiet and vibration-free, no exhaust gas from the engine is emitted, and the bed is cooled with extremely good thermal efficiency. The purpose is to be able to take a good night's nap and to be easy to use even outdoors because it is portable.

[Embodiment of the invention]

 FIG. 1 is a front view showing a cool storage cooler box according to the present invention, FIG. 2 is a left side view thereof, FIG. 3 is a sectional view taken along line AA in FIG. 1, and FIG. FIG. 4 is a cross-sectional view of B, mainly for bed room cooling provided in the cabin of a long-distance truck. As shown in FIGS. 3 and 4, the casing 14 is divided into a vertical upper chamber 15 and a lower chamber 16, and the (super heat conduction tube) cold air discharge section 17a of the heat pipe type heat exchanger 17 is connected to the lower chamber. The cooling fins 18 are arranged in multiple stages across the cold air discharging portion 17a, and a fan 19 for blowing air and a louver 20 for blowing cold air are provided in the lower chamber 16. The heat pipe type heat exchanger 17 contains a working fluid 17c. The cold air absorbing portion 17b of the heat pipe type heat exchanger 17 faces the upper chamber 15, and a cold storage material (cool storage pack) 21 packed with a liquid is inserted into the formed space so as to be able to be inserted and removed, and the truck runs. The cold storage material 21 is kept cool in the interior. A portable cold storage cooler box to which a handle 22 for carrying or a band (not shown) can be attached to an appropriate position of the housing 14 can be provided. A lid 23 is provided on the top of the housing 14 so as to be openable and closable. The housing 14 and the lid 23 are covered with a heat insulating material 24, and a power supply line 25 is connected to a cigarette lighter power supply or a battery box power supply. Reference numeral 26 denotes a fixing screw for the housing 14. Use the cold storage material frozen in a refrigerator (freezer) for 10 hours or more.

[0006]

[Effect of the invention]

 Due to the action of the cold storage material 21 cooled in the refrigerator (freezer), the engine is not started even when the truck is stopped, and the vehicle is quietly powered by weak electric power from the on-board battery or dry battery, without emitting exhaust gas and without thermal efficiency. Very good bed cooling can be performed. The on-board battery is used only with weak power, so there is no worry about the battery going up. Further, since the air is not directly blown to the cold storage material 21, the cool air is comfortable without moisture. Furthermore, it has versatility that can be used irrespective of the type of vehicle, and because it is portable, it can be easily used outdoors.
