[0002] Traditional display cabinet heating shelves are generally heated by attaching a layer of electric heating wire under the sheet metal shelf. This method does not allow for uniform surface temperature and large temperature fluctuations. The heating wire is frequently disconnected, consuming more electricity, and may pose electrical safety risks such as leakage. Utility Model Content

[0003] The utility model aims at the deficiencies existing in the prior art and provides a display cabinet heating layer plate which can improve heating uniformity, has a certain energy storage function and completely eliminates electrical safety risks such as leakage.

[0009] When the display cabinet heating layer plate of the utility model is working, the heat-conducting medium is retained from the inlet, flows out from the outlet, and circulates in the layer plate, so that the entire layer plate can be evenly heated; at the same time, the heat-conducting medium plays a role of energy storage, and when its temperature reaches the set temperature, the heat supply side cuts off the supply, and the heat stored in the heat-conducting layer plate itself can extend the cut-off time, thereby achieving the purpose of energy saving.

[0010] As an optional solution of the technical solution of the utility model, at least one group of heating coils is provided in the hollow chamber;

[0011] The two end ports of the heating coil are respectively connected to the heat transfer medium inlet and the heat transfer medium outlet.

[0012] The display cabinet heating shelf of this solution includes a closed shell, in which a heat transfer medium coil pipeline is arranged, and the closed shell is filled with liquid heat transfer medium. When working, the heat transfer medium circulates from the built-in coil, and the liquid heat transfer medium in the shell is heated by the coil. After the heat transfer medium becomes hot, the entire shelf is evenly heated.

[0013] As an optional solution of the technical solution of the utility model, the heat-conducting medium inlet and the heat-conducting medium outlet are connected with a heating device and a medium circulation mechanism.

[0014] As an optional solution of the technical solution of the utility model, the heat-conducting medium is gas, and the medium circulation mechanism is a circulation fan.

[0015] As an optional solution of the technical solution of the utility model, the heat-conducting medium is liquid, and the medium circulation mechanism is a circulation pump.

[0016] As an optional solution of the technical solution of the utility model, reinforcing ribs or spacer strips are provided in the hollow cavity.

[0017] The beneficial effects of the utility model are:

[0018] (1) The display cabinet heating layer of the utility model adopts a heat-conducting medium to directly heat the layer, replacing the traditional electric heating wire heating method, and there is no electrical safety risk such as leakage;

[0019] (2) The layer plate is a closed hollow structure filled with heat-conducting medium, which has a certain heat storage and energy storage function and can reduce the temperature fluctuation of the layer plate;

[0020] (3) The heat is transferred from the external heater device to the layer plate through the flow of the heat-conducting medium, thereby continuously heating the layer plate; the heat-conducting medium directly contacts and exchanges heat with the layer plate, the contact heat transfer area is large, and the heat transfer efficiency is high.
