Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of charging and battery replacing cabinet, and particularly relates to a battery compartment heating air duct structure for a battery replacing cabinet and the battery replacing cabinet. BACKGROUND

[0002] Since the charging efficiency of the battery is very low under low temperature, and even cannot be charged, a heating air duct is usually arranged in the battery replacing cabinet to heat the battery replacing cabinet under cold weather. However, the existing heating air duct usually has one horizontal main air duct, and then communicates with a plurality of vertical air ducts, such as the utility model patent CN 212765825 U discloses a charging and battery replacing cabinet. However, the problem is that since the hot air is lighter, it will float upwards, and since the ground temperature is lower than the air temperature in cold weather, the temperature of the battery compartment of the battery replacing cabinet closer to the bottom is lower, and needs more heating; this results in that the battery compartment at the bottom which needs more heating gets less heating energy, and the battery compartment at the upper part which needs less heating gets more heating energy, which leads to the waste of energy, and therefore needs to be improved. In addition, the existing battery replacing cabinet heats all the battery compartments, but there are usually empty battery compartments in the battery replacing cabinet, and heating them also leads to the waste of resources.

[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the utility model embodiment will be clearly and completely described below in conjunction with the drawings. The embodiments of the application are described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the application, and cannot be understood as limiting the application.

[0020] Embodiment 1

[0021] As Figures 1-3As shown in one kind for battery swap cabinet battery compartment heating air duct structure, including vertical total air duct 1, heating fan 2, communication port 3, horizontal air duct 4, auxiliary air duct 41, air inlet 42, battery compartment 5, ventilation port 51, bolt 52, spring 53, partition 54, through slot 55, baffle 7 and air control port 71.

[0022] Wherein, total air duct 1 vertical setting, total air duct 1 bottom communication has heating fan 2 and from bottom to top in turn through the communication port 3 has several horizontal air duct 4, horizontal air duct 4 is communicated in the same row battery compartment 5 respectively, wherein, total air duct 1 is installed with several baffle 7, baffle 7 and total air duct 1 inner wall between the air control port 71 is formed, air control port 71 from bottom to top in turn smaller;Baffle 7 is between the two adjacent communication port 3.

[0023] In this way, by the setting of baffle 7, control the size of communication port 3, so that most of the hot air into the bottom of horizontal air duct 4 connected battery compartment, so that the whole battery compartment heating is more uniform, thereby saving energy.
