PROBLEM TO BE SOLVED: To provide a portable cooling device that enables sufficient cooling efficiency to be acquired even if it is downsized.SOLUTION: A portable cooling device 1 includes a compressor 104 for compressing a cooling medium, a condenser 105 for liquefying the compressed cooling medium, an evaporator 110 for evaporating the liquefied cooling medium and generating ice from cooling water by evaporation heat, an ice storage tank 108 for storing cooling water in which the evaporator 110 is disposed, and a circulation pump 113 for circulating the cooling water in the ice storage tank around a cooled object. The portable cooling device 1 may further include a temperature sensor 112 disposed below the evaporator 110, and a control part 101 for switching the operation of the compressor 104 from ON to OFF when it is determined that the temperature detected based on the output of the temperature sensor 112 is below a first threshold, and switching the operation of the compressor 104 from OFF to ON when it is determined that the temperature is above a second threshold higher than the first threshold.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】小型化しても十分な冷却効率が得られる可搬型冷却装置を提供する。【解決手段】可搬型冷却装置1は、冷媒を圧縮する圧縮機104と、圧縮された冷媒を液化する凝縮器105と、液化した冷媒を気化し、気化熱によって冷却水から氷を生成する蒸発器110と、冷却水を収容し、内部に蒸発器110が配置される蓄氷タンク108と、蓄氷タンクの冷却水を被冷却物の周りに循環させる循環ポンプ113と、を備える。また、可搬型冷却装置1は、蒸発器110の下方に配置された温度センサ112と、温度センサ112の出力に基づいて検知した温度が第1閾値を下回ったと判定した場合、圧縮機104の動作をONからOFFに切り替え、第1閾値より高い第2閾値を上回ったと判定した場合、圧縮機104の動作をOFFからONに切り替える制御部101と、をさらに備えていてもよい。【選択図】図2
