The present invention relates to a thermal mat, and more particularly, to a working fluid transfer apparatus of a thermal mat for transferring a working fluid of the thermal mat.

In general, the heating mat is provided with a heating wire therein, so that the heating is easily provided by supplying power to the heating wire.

However, the electric field is generated by the heat generated by the heating wire installed as described above, and the electromagnetic field emits harmful electromagnetic waves (EMI), which is not good for objects or living things.

That is, since the human body and the heating wire are closest to each other by the weight of the user, it is well known that a large amount of harmful electromagnetic waves are directly induced to the human body and thus have a very detrimental effect.

In order to solve this problem, a thermal mat for heating and circulating a fluid containing oil or water has been proposed.

However, such a conventional thermal mat can be completely escaped from harmful electromagnetic waves by heating the working fluid separately and circulating it with the heating mat, but since the circulation pump for moving the working fluid must be installed separately, the part material cost and the production process cost This raises, the space utilization is lowered, that is, the volume of the thermal mat was unnecessarily large.

Therefore, the present invention has been made to solve the problems of the prior art as described above, by circulating the working fluid as a pressure roller instead of a pump to reduce the material cost and production process cost, that is, production cost and volume of the thermal mat It is an object of the present invention to provide a working fluid transfer device of a thermal mat so as to minimize it.
