1. A flow guiding and heat dissipating type dry block temperature calibrator comprising:
a housing;
a furnace body disposed in the housing;
at least one air flow generating device disposed in the housing and at a periphery of the furnace body, wherein an air flow generated by the air flow generating device is blown toward a handle of a device to be tested that is inserted into the furnace body; and
a cooling fan disposed in the housing and below the furnace body, wherein
the air flow generating device comprises:
one or more gas passages arranged on the periphery of the furnace body and communicated with the cooling fan or other gas sources, the gas passage being provided at a bottom end thereof with an air inlet for entering of the air flow, and at a top end thereof with an air outlet for flowing of the air flow to the handle of the device to be tested, and
at least one of a flow guiding fan, an air pump and a blower provided inside the gas passage; and
the gas passage is a rectangular parallelepiped cylinder enclosed by a control board and a control board bracket for installing the control board, wherein the control board bracket is of a rectangular groove structure, a side opening of which is partially covered by the control board, and wherein a mounting plate is provided at an air outlet of the rectangular parallelepiped cylinder, the flow guiding fan is mechanically fixed below the mounting plate, and the mounting plate is provided with an opening corresponding to the position of the flow guiding fan.
