    Abstract: PURPOSE:To permit the home delivery system of cold reserving materials having a plurality of temperatures and eliminate the affection of a defrosting system to the other chambers reserving cold materials by a method wherein the chambers of the cold reserving materials can be switched between plus temperature zone and minus temperature zone for refrigerated materials and frozen materials while the minus temperature zone is switched to the plus temperature zone after the opening and closing operation of a door. CONSTITUTION:The selective switches 32, 33, 34 of 5 deg.C, 0 deg.C, -18 deg.C and indicating LEDs 35, 36, 37, corresponding to respective selective switches, are arranged on the front surface of respective heat insulating doors 7 while the selective switches and the indicating LEDs are incorporated into a temperature selective circuit, for setting the temperatures of respective compartments 5a, 5b, 5c at 5 deg.C, 0 deg.C, -18 deg.C, together with a door switch 14 also serviceable as a lamp. The opening and closing signal of the door switch 14, also serviceable as a lamp, is connected so as to be inputted into the LED 34 of 5 deg.C and an IC timer 38 to light the LED 35 of 5 deg.C at all times after opening an heat insulating door 7 while the operation of only the circuit of 5 deg.C of temperature control circuit can be effected by an output A.

    Abstract: PURPOSE:To hold constant temperature and prevent freezing by forming a chill accumulator in which chill accumulating agent is arranged and a heat accumulator in which heat accumulating agent is arranged in a box body forming a container, and introducing the heat of fusion of the chill accumulating agent or the heat accumulating agent in the box body according to outside air temperature. CONSTITUTION:When a power source is switched on, a compressor 12 is turned on elecrtricity at high outside air temperature (0 deg.C or higher), a heater 17 is selectively turned on electricity at low outside air temperature (-3 deg.C or lower), and chill accumulating agent 10 and heat accumulating agent 16 are accumulated to coagulate and fuse respectively. At this time a fan motor 18 is not turned on electricity by a relay 30 and chill and heat accumulation are efficiently performed in a chill accumulating chamber 5 and a heat accumulating chamber 6. After chill or heat accumulation is completed, a thermostat 25 or 26 is turned off and the completion is shown by a completing lamp of a body and the like. When chamber temperature is at 0 deg.C or higher by a thermostat 29, the fan motor 18 is operated and the chill in the chill accumulating chamber 5 is circulated and held at constant temperature. Reversely, when outside air temperature is at -3 deg.C or less, the heat accumulating agent 16 is fused by the heater 17, the fan motor 18 is operated and heat of the heat accumulating chamber 6 is introduced by sensing of the thermostat 29 even if chamber temperature is lowered in the condition that goods are carried in a chamber 2.

    Abstract: PURPOSE:To make it possible to increase the nuclear boiling effect of the titled heat pipe without applying any specific processing on the pipe by a method wherein a working liquid and magnetic metallic particles are sealed within the sealed heat pipe made of a non-magnetic material and the fins attached to the working liquid storage section of the heat receiving section of the heat pipe is made of a magnetic material. CONSTITUTION:The finned heat pipe 1 is formed of the non-magnetic metallic pipe 6 and a number of L-shaped plate fins 7 attached normally to the heat receiving section 4 and a coolant 8 of about 10 to 20% of the entire volume of the pipe 6 and a small amount of magnetic needle-like metallic particles are sealed with the pipe 6. Further, the lowermost plate fin 7' is made of a magnetic iron plate while the remaining fins 7 are made of a non-magnetic aluminum material. Consequently, the metallic particles 9 gather in the shape of a circle on the inner wall of the pipe 6 at position corresponding to a collar 7a' of the lowermost fin 7' and the nuclei of boiling generate in the coolant 8 at the metallic particle gathering position to thereby accelerate the rising of boiling and to improve the lower temperature characteristic of the pipe. Thus it is possible to increase the thermal efficiency of a solar heat collector or the like using the pipe.
