Embodiments of the present disclosure provide a battery heating system, a battery assembly and an electric vehicle. The battery heating system includes: a battery group having a positive terminal and a negative terminal; a switch having a first end connected with the positive terminal; a large-current discharge module, and a controller connected to the switch and configured to control the switch according to a temperature of the battery group. A first end of the large-current discharge module is connected to a second end of the switch, and a second end of the large-current discharge module is connected to the negative terminal. When the switch is turned on, the battery group discharges via the large-current discharge module and the battery group is heated due to an internal resistance thereof.

A cooling device includes an electrode unit which is arranged in a space between adjacent radiation fins and which is electrically insulated from the radiation fins, and a power supply source which applies a voltage between a heat radiation structure and the electrode unit. The cooling device is further provided with an insulation resistance detection unit which calculates an insulation resistance between the heat radiation structure and the electrode unit, and a comparison unit which compares the insulation resistance calculated by the insulation resistance detection unit with a predetermined threshold, wherein, as a result of the comparison of the calculated insulation resistance and the predetermined threshold by the comparison unit, when the calculated insulation resistance is lower than the predetermined threshold, the cooling device is adapted to judge that the radiation fins have clogged.

A knockdown heat dissipation unit includes at least one combination body and multiple heat pipes. The combination body has two opposite connection sections. The heat pipes are respectively connected with the connection sections of the combination body to form a large area of thermal contact face. According to the structural design of the knockdown heat dissipation unit, the number of the heat pipes can be increased or reduced according to the heat dissipation requirement of a user. Also, the number of the heat pipes can be flexibly adjusted according to the size of a heat source to enhance the heat dissipation effect.

The present disclosure provides, among other things, a radiator system, its components, as well as methods of mounting and/or installing thereof. Provided components include radiating fins arranged around a water pipe to form a core assembly. The radiating fins may include a collar and/or reflare and are spaced in the core assembly to permit airflow through the system. The core assembly may be mounted by support elements on hangers from a back plate which is wall mountable. The support elements may create space for airflow between the core assembly and a front casing and/or the back panel. Provided systems, components and methods are useful in commercial and residential baseboard radiators.

A pallet cover suitable for use in covering at least a portion of a payload on a pallet and a kit for use in making the pallet cover. In one embodiment, the pallet cover includes a top wall, a front wall, a rear wall, a left side wall, and a right side wall, wherein the walls are detachably joined to one another. Each of the top wall, the front wall, the rear wall, the left side wall, and the right side wall includes a first fabric sheet and a second fabric sheet, the first and second fabric sheets being joined together to form a plurality of pockets. Each pocket may removably receive a temperature-control member containing a phase-change material. At least one of the top wall, the front wall, the rear wall, the left side wall and the right side wall includes a plurality of detachably joined portions.

An air conditioning case includes a first partition wall that receives a condensed water generated by an evaporator, and the first partition wall is disposed above an overlapped portion of a heater core and between the evaporator and the heater core. Therefore, the first partition wall can prevent the condensed water dropped from the evaporator from being applied directly to the heater core. As a result, in a structure in which at least a portion of the heater core overlaps with the evaporator from below, the condensed water of the evaporator is less likely to be applied to the heater core.
