Abstract: A heat module includes a heat receiving portion, a fluid channel, a fan, a radiator including heat dissipating fins and a radiator tube fluid channel, and a pump. The pump includes a stationary portion and a rotating portion. The rotating portion includes a rotor holder and a pump impeller. The pump further includes a casing, a pump fluid channel, a pump inlet, and a pump outlet. At least a portion of the rotor holder and at least a portion of the pump impeller are arranged to radially overlap with each other. The fluid channel includes a tube fluid channel. The tube fluid channel includes a pump inlet-side tube fluid channel, a pump outlet-side tube fluid channel, and a heat receiving portion tube fluid channel. No heat receiving portion tube fluid channel is arranged in the pump inlet-side tube fluid channel.
