It addition, also have the mode of other close contacts, between flattened medial heat exchanger tube portion and ptc heater, such as insert wedge shape inserted sheet。
Certain this utility model may be used without fastening structure, and described fastening structure makes close contact heat exchange between flat heat exchange tube portion and the ptc heater of flat fluid channel tube。Described fastening structure can adopt and run through bolt and nut, runs through bolt and passes sequentially through each flat fluid channel tube, and opposite side is tightened with respective nut。Or described fastening structure can adopt pressing plate, pressing plate is placed in both sides, flat heat exchange tube portion, run through bolt through after pressing plate with corresponding nut screwing clamping。It should be noted that for the liquid medium firing equipment described in this utility model, above-mentioned various retention mechanisms are optional, but are only used as available option。
Further, described liquid medium firing equipment is provided with inlet and liquid outlet。
Heat exchanging liquid used by this utility model liquid medium firing equipment preferably employs water base coolant, such as pure water or conventional anti-icing fluid, and wherein the host component of anti-icing fluid is 50% water of about 50% ethylene glycol+about。
Compared to prior art, the mode inserted soon preferably by snap joint between the adjacent import of this utility model (or outlet) end connects, and this connected mode is quick and tight, and can guarantee that ptc heater and fluid channel tube intimate contact heat transfer。So can avoid using the unnecessary special retention mechanisms such as push part。
The beneficial effects of the utility model are: product heat transfer efficiency of the present utility model is high, power density is big, compact conformation, volume are little, and cost is low, and assembles simple。
