Embodiment
Referring to Fig. 1 and Fig. 3, the utility model comprises heater 1, recycle pump 2, joiner 3, this joiner 3 has three interfaces, one is heat eliminating medium inlet 31, another is outlet 32, another is a floss hole 33, and described outlet 32 is connected with the inlet 11 of heater 1 by pipeline 4, and the outlet 12 of this heater 1 is connected with the inlet 21 of recycle pump 2; On the floss hole 33 of described joiner 3, escape cock 34 is arranged; In the outlet 22 of described recycle pump 2, one-way valve 23 is arranged.
The utility model also is provided with control gear, comprise controller 51, two temperature transducers 52 and 53, temperature transducer is separately positioned in the described joiner 3 and in the heater 1, its signal end is connected with the corresponding end of controller 51, and the power supply of the power supply of heater 1 and recycle pump 2 connects with the corresponding control end of described controller 51 respectively; On described controller 51, also be connected with warning sound communication device Y.
The inlet 31 of joiner 3 of the present utility model and the outlet 22 of recycle pump 2 are connected with inlet with the floss hole of motor car engine heat eliminating medium case respectively, make heat eliminating medium form the circulation loop of envelope valve.
Referring to Fig. 2, heater 1 of the present utility model comprises shell 13, cap 14, electric heating element R, insulation end shield 15, the end sealing of shell 13, the other end has open ports, at its closed end described outlet 12 is arranged, its open ports and close connection of cap 14 liquid can adopt to be threaded and to add seal ring.Electric heating element R is positioned at shell 13, and its end passes cap 14 and is rotary with tenminal block, and the interface 16 of described inlet 11 and temperature transducer 53 is arranged on the cap 14, is with isolated junction cover 15 outside this cap 14.
Referring to Fig. 4, this embodiment of the utility model control gear has adopted three temperature sensitive relay TJ1-TJ3, and wherein TJ1 and TJ2 all place on the joiner 3, and TJ1 is as the low-temperature warning switch, and is connected with power supply E with sound communication device Y series connection back; TJ2 is as the temperature control switch, is connected with power supply E with the coil series connection back of the control relay J1 of electric heating element R.Above-mentioned TJ3 is arranged in the heater 1, connects as the overtemperature prote switch and with the coil of protective relay J2, and its power supply is supplied with after transformer B step-down and rectifier bridge Q rectification by civil power AC220V.Be connected with AC220V with electric heating element R series connection back after the contact series connection of J1 and J2, the power supply of recycle pump 2 is in parallel with electric heating element R again.
