NOVELTY - The module (100) has a covering structure (120) including a gap between a block wall and a side wall to form a zigzag air channel. An electric equipment set (130) i.e. battery pack, is placed in a containing space (110a) of a housing (110). A fan (140) provides air flow. A ventilator (110c) is formed on the housing or structure. Air flows into the space through the channel and another ventilator (110b), and flows out through the former ventilator or flows into the space through the former ventilator and flows out through the latter ventilator and the channel.    USE - Car electric equipment case module for encasing an electric equipment set i.e. battery pack, of an electric vehicle i.e. car. Can also be used for encasing a controller set for propelling an automotive electronic device i.e. automotive motor.    ADVANTAGE - The covering structure covers the ventilator, so that the air flows into or flows out of the housing through the channel and the ventilator for heat dissipation, where the housing can be protected from external moisture or dust entering into the housing through the ventilator by covering the ventilator with the covering structure, so that the electric equipment set is less likely to be in contact with a foreign material, thus avoiding damage or ineffectiveness of the electric equipment set. The covering structure achieves water-proof and dust-proof protection to avoid the need for configuring a wind-guiding cover to move air intake and air exhaust to a set of positions that are less likely to be affected by external moisture or dust, thus economizing a configuration space of an entire structure of the module. The block wall extends from a set of peripheries of a casing and surrounds the housing to cover the latter ventilator and allows the channel to surround and extend from the casing, thus increasing total cross-sectional area of the channel, and hence improving air circulation efficiency of the module. The module has a set of honey-comb shaped openings formed in the covering structure, such that heat-dissipating air can flow through the openings, thus enhancing water-proof and dust-proof protection of the electric equipment set.
