Abstract
Description
Technical Field
[0001] The utility model belongs to the field of fuel cell vehicles and relates to a waste heat recovery device for a fuel cell vehicle, in particular to a waste heat recovery device for an air-cooled fuel cell sightseeing vehicle. Background Art
[0002] Sightseeing buses are vehicles set up in tourist attractions for the convenience of tourists. Sightseeing buses are widely used in hotels, scenic spots, house viewing, factories, airports, railway stations, bus stations, docks, stadiums, parks and other places. Due to the special functions of the vehicle, sightseeing buses are usually not completely enclosed or incompletely enclosed.
[0003] When sightseeing buses are running in autumn and winter, the low temperature will reduce the riding comfort because the carriage cannot be closed or is not closed tightly. Most existing technical solutions do not have seat heating in sightseeing buses, or use electric heating, which cannot provide this comfort function, because the use of electric heating will seriously affect the endurance and attendance rate. Air-cooled fuel cells are often used as the power source of sightseeing buses. When working, they will generate heat that is about 40% of the fuel consumption. If the heat can be recovered to heat the passenger seats, the heat energy can be effectively utilized to improve the riding comfort. Utility Model Content
[0004] The utility model provides a waste heat recovery device for an air-cooled fuel cell sightseeing vehicle, aiming to improve the riding comfort of the air-cooled fuel cell sightseeing vehicle in autumn and winter without increasing energy consumption.
[0005] The purpose of the utility model is achieved by at least one of the following technical solutions.
[0006] A waste heat recovery device for an air-cooled fuel cell sightseeing vehicle, wherein an air-cooled fuel cell, a cooling fan, a waste heat recovery heat exchanger and a heat exchanger are arranged at the bottom of the sightseeing vehicle body; a cooling fan is arranged on one side of the air-cooled fuel cell, and a waste heat recovery heat exchanger is arranged on the other side of the cooling fan; the waste heat recovery heat exchanger is connected to the heat exchanger through a pipeline.
[0007] Further preferably, the heat exchanger is located at the bottom of the vehicle seat.
[0008] Further preferably, a water pump is provided on the pipeline between the waste heat recovery heat exchanger and the heat exchanger.
[0009] Further preferably, the heat exchanger under each seat is connected in series with the waste heat recovery heat exchanger.
[0010] Further preferably, the waste heat recovery heat exchanger is a finned heat exchanger.
[0011] The utility model is not limited to sightseeing vehicles, but includes other land vehicles that use air-cooled fuel cells as power or auxiliary power generation.
[0012] Compared with the prior art, the advantages of the present invention are:
[0013] The utility model improves the internal structure of the sightseeing car and uses only very little additional power, that is, the power of the circulating water pump, to achieve the seat heating function of the sightseeing car, thereby saving energy, reducing emissions, lowering costs and increasing efficiency.
[0014] The utility model improves the riding comfort of the air-cooled fuel cell sightseeing vehicle in autumn and winter without increasing energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

The air-cooled fuel cell 1, the cooling fan 2 and the waste heat recovery heat exchanger 3 are arranged in the front, middle and rear parts of the air flow, respectively, and are a heat generating device, a component driving the air flow, and a heat exchange component. The air flow direction is as shown in FIG. Figure 1The arrow in the middle points to the direction. In this embodiment, the waste heat recovery heat exchanger adopts a finned heat exchanger. The waste heat recovery heat exchanger 3 is connected to the heat exchanger 5 located at the bottom of the vehicle seat 6 through a pipeline. Specifically, Figure 2 As shown, in this embodiment, the air-cooled fuel cell 1 generates heat during use, which is dissipated by the cooling fan 2, and the hot air is blown into the waste heat recovery heat exchanger 3, and the waste heat is absorbed to heat the liquid water in the waste heat recovery heat exchanger 3; at the same time, a circulating water circuit is arranged at the lower part of the seat 6, and is connected to the waste heat recovery heat exchanger (fin heat exchanger) through a silicone hose to realize the waste heat utilization.
