Abstract: In order to improve the efficiency of solidification and melting of a heat storage material in a heat storage material unit, a heat storage material covered with a coating material is accommodated in a metal accommodating container having a high thermal conductivity, and the heat storage material unit is embedded in a thermal insulation panel in such a way that the accommodating container is exposed inside a merchandise accommodating compartment, thereby enabling a surface of the heat storage material that is embedded in the thermal insulation panel also to exhibit an action equivalent to that if the accommodating container is exposed in the merchandise accommodating compartment as a heat transfer element, thereby improving the efficiency of solidification (heat storage) and melting (heat dissipation) of the heat storage material.

Abstract: The disclosure discloses a mobile photoelectric detection and identification system for low, slow and small targets. The optical detection subsystem and the photoelectric parallel processing and identification subsystem are arranged on the servo subsystem, and the servo subsystem is carried on an installation platform of a vehicle. The optical detection subsystem is configured to collect multi-wavelength band optical information from the target and the background. The co-processing module of various wavelength bands is configured to perform single-frame detection and identification of the target from the image information of the corresponding wavelength band. The information processing main control module is configured to use JPEG image compression, track association and multi-frame combining methods to perform a multi-frame detection and identification on the target. The servo subsystem is configured to complete target tracking according to the multi-frame detection and identification results.

Abstract: A vending machine includes: an in-storage heat exchanger installed in an airtight heat-insulated commodity storage inside a vending machine body and configured to exchange heat between a refrigerant passing through a refrigerant flow path of the in-storage heat exchanger and inside air that is air inside the commodity storage, through a fin member; and an out-storage heat exchanger installed outside the commodity storage inside the vending machine body and configured to exchange heat between a refrigerant passing through a refrigerant flow path of the out-storage heat exchanger and outside air that is air surrounding and outside the commodity storage, through a fin member. The fin member of the in-storage heat exchanger includes louvers configured to cause the inside air passing through the airflow path to generate a meandering flow. The fin member of the out-storage heat exchanger has no louvers.
