Abstract

A heating module for recreational vehicles (RVs), including a heat exchanger, a heating water inlet, a heating water outlet and a cold water inlet. The heat exchanger communicates with the heating water inlet. A side of the heat exchanger is provided with a fan to generate air flow, so as to carry the heat generated by the heat exchanger to an interior of the RV. The heating water inlet communicates with a water outlet of a water heater. The heating water outlet is connected with the heat exchanger, and a water pump is provided on a pipeline between the heating water outlet and the heat exchanger. The cold water inlet is configured to be connected with tap water or a water storage tank of the RV. A water flow sensor is provided on the cold water inlet.

Claims (13)

1 . A heating module for recreational vehicles, comprising:

a heat exchanger;

a heating water inlet of the heating module;

a heating water outlet of the heating module; and

a cold water inlet of the heating module;

wherein an inlet end of the heat exchanger communicates with the heating water inlet of the heating module; a side of the heat exchanger is provided with a fan; the fan is configured to generate an air flow to carry heat generated by the heat exchanger to an interior of a recreational vehicle; and the heating water inlet of the heating module communicates with a water outlet of a vehicle-mounted water heater;

the heating water outlet of the heating module communicates with an outlet end of the heat exchanger, and a water pump is provided on a pipeline between the heating water outlet of the heating module and the outlet end of the heat exchanger; and

the cold water inlet of the heating module is configured to communicate with a tap water source or a water storage tank of the recreational vehicle; the cold water inlet of the heating module communicates with the heating water outlet of the heating module; the heating water outlet of the heating module communicates with a water inlet of the vehicle-mounted water heater; and a water flow sensor is provided on the cold water inlet of the heating module.

2 . The heating module of claim 1 , further comprising:

a controller;

wherein the controller is electrically connected with the fan and the water pump; and the controller is also electrically connected with a temperature sensor in the recreational vehicle.

3 . The heating module of claim 1 , wherein a check valve is arranged on the heating water outlet of the heating module.

4 . The heating module of claim 1 , wherein a check valve is arranged on the cold water inlet of the heating module.
