Detailed Description

Reference will now be made in detail to embodiments of the present invention. Although the present invention has been illustrated and described with reference to these embodiments, it should be noted that the present invention is not limited to these embodiments. On the contrary, the invention is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the invention as defined by the appended claims.

The utility model provides a new energy automobile series connection heat reclamation device, as shown in figure 1, include through the cooling liquid main line series connection and form the radiating part of return circuit, a weighing sensor and a temperature sensor, the PTC heater, the driver's cabin heat exchanger, the driver's cabin fan, whole car radiator, a water pump, radiating part includes new energy automobile's the electricity system of driving, hydrogen fuel pile system, battery and PDU, adopt the cooling liquid to divide the pipeline to connect in parallel to collect and be connected to the cooling liquid main line between each radiating part, each cooling liquid divides the pipeline more with air area of contact, the radiating effect is better.

In addition, the cab heat exchanger is a plate heat exchanger, and the heat exchange plate is a corrugated heat exchange plate. The plate pack is firmly pressed in the frame and the support points on the corrugated heat exchanger plates keep the plates apart so that small channels are formed between the plates, liquid enters the channels through holes in one corner of the plate and the closing of the holes is changed so that liquid can pass from one channel to another. The gasket at the periphery of the plate and the periphery of the hole forms a channel boundary to prevent outward infiltration from mixing with the internal fluid stream.

The temperature sensor is electrically connected with the PTC heater through the PTC controller, an air conditioning fan of the cab is arranged behind the heat exchange plate of the cab heat exchanger, and a switch of the cab fan is electrically connected with the PTC controller. Here, the PTC controller is of type PT2259-S and the cab fan switch is the cab air conditioner hot air knob.

The hot air knob of the air conditioner of the cab is turned on, the fan of the cab works, the PTC controller reads the numerical value of the temperature sensor, when the temperature is lower than the set value, the PTC controller controls the PTC heater to be turned on, the cooling liquid is heated to the set value, and the PTC heater stops working; the heated cooling liquid flows to a cab heat exchanger through a cooling liquid main pipeline, after high-temperature cooling liquid flows into the heat exchange plate, air blown out by a cab fan exchanges heat with the cooling liquid, and the air absorbing heat released by the heat exchange plate is heated and then is sent into the vehicle through each air outlet by the fan; after the heat exchange plate provides heat required by heating of a cab, cooling liquid returns to a whole vehicle radiator through a cooling liquid main pipeline so as to achieve cyclic utilization of heat energy. In the whole process, the water pump and the heat dissipation part work to dissipate heat of the main drive system.

When the PTC controller reads that the value of the temperature sensor is equal to or higher than a set value, the PTC heater is kept closed, high-temperature cooling liquid flowing out of the heat dissipation component directly flows through the temperature sensor and the PTC heater to reach a heat exchange plate of the cab heat exchanger, air blown out by a cab fan exchanges heat with cold liquid, and the air is heated and then is sent into the vehicle through air outlets by the fan.

The cab fan is closed, the PTC controller controls the PTC heater to keep a closed state at the same time, the cooling liquid flows to all radiating parts from the whole vehicle radiator, sequentially flows through the temperature sensor, the PTC heater and the heat exchanger through the cooling liquid main pipeline, and finally returns to the whole vehicle radiator for circulation. The temperature sensor, the PTC heater and the cab heat exchanger do not work, and the heat dissipation loop is used as a heat dissipation loop of the whole vehicle heat dissipation system.

As above, while the invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limiting the invention itself. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
